My dad got his left leg practically blown off in the Big One and what's left doesn't work very well. And a buddy who travels with me on occasion has had a lung transplant. Funny, all three of us seem to be quite mobile on our 2-wheel electric scooters. What I can't understand is why there are dickheads in this world who, apparently failing at minding their own business properly, seem to feel the need to mind everyone elses' business. Never have figured that one out. John

IMHO, it is a non-starter, an overly complex solution to a problem that either does not exist or is solved by much simpler and cheaper solutions. It is too big, too heavy, too complex and too complicated. Plus by virtue of using an active gyro-based servo loop to maintain balance, it is inherently fail-dangerous. Anything that interrupts normal operation - be it a processor crash or simply a loose wire or battery opening up - will cause the device to lose balance and eject the passenger - that is, unless the passenger is skilled at unicycle riding :-) As I noted in another post, there is a wide variety of high quality electric scooters already on the market that do everything the Segway will do but without the cost or complexity. As you noted, the electric scooter can solve a number of urban problems that massive public dollars have so far failed to address. Urban traffic congestion and pollution are just two. For folks like me who live in a downtown area, the scooter takes care of 90% of my transportation. The only time I crank my car is to go across town, to go out of town or to make a restaurant delivery. And I'm building a powered trailer for my scooter to address most of that last requirement. I'm probably more hard core than most folks because I travel by scooter in all weather except hard rain, including cold. An example is my daily commute to the bank to make the restaurant deposit. It is one mile round trip. My scooter uses 2 amp-hours, 48 watt-hours, to do the commute. I require no parking spaces and occupy no roadway. I use sidewalks and alleys and even traveling at a pedestrial-compatible 5 mph, I almost always beat cars over the same route. The energy cost for that trip is 0.18 cents. My vehicle cost $179. I get about 1000 miles to an 8 dollar tire. I'll replace the $75 batteries after probably 2500 miles. That's cheap transportation and is fun as heck to boot. Even if you live too far away from work to commute on the scooter, it can still be useful. One way is, as you noted, commuting from the rail station. Another is to carry the scooter in your car trunk and use it to either commute from a satellite parking lot out of the city core or to run your lunch time errands. I could have used such a setup when I was commuting from the Atlanta 'burbs to my high-rise in the Lenox area. Just about everywhere I needed to go for lunch was within a couple of miles of my office. I hated to crank up my car just to drive a couple of miles. Inconvenient, wasted a lot of time and was hard on the engine. All this is happening on the left coast and in certain northeastern cities. There the scooter culture is booming. And unlike the bleatings of the anti-destination leaguers, scooters and pedestrians happily coexist. Unfortunately there are too many people in this world like Tom J who see these things as toys and who hate to see folks enjoy themselves. Laws and lawsuits will be necessary to move these folks out of the way. A perfect example was a couple of weeks ago over the Thanksgiving weekend. we went to the Daytona Turkey Rod Run at the speedway. Doreen had a cast on her foot. We both had handicapped placards on our scooters and yet we were not allowed in the speedway by security. After a couple of hours of working our way up through the hierarchy, I had a heated discussion with the show promoter. He said that our scooters "didn't look like assist devices" and that he was not going to allow such toys in the show. I pointed out that the ADA required reasonable accommodations. No go. Soooo. We're interviewing lawyers for the ADA suit. If the Segway does anything, it will be to raise the awareness of the general public to electric scooters and other personal mobility devices. Most of the commercial folks on the scooter mailing list have noticed huge increases in web site traffic since the hype peaked. If sales and political change follows, the Segway will be worth the hype. BTW, there is an active mailing list on yahoo. It's the zappy list, originally started for the zappy electric scooter but now embracing all sorts of electric personal transportation. John

Date: Wed, 05 Dec 2001 05:55:37 -0500 Well, it's too big, too heavy, too complicated, too expensive and too much a power hog but other than that, it's cute. I've been involved in the electric scooter world for quite some time (I have 5 currently, not the geezer scooters but high performance 2 wheel jobbies.) and I was so underwhelmed by this thing that words fail me. The limiting factor with any electric scooter is energy storage (batteries) and nothing this whiz kid can do with electronics can fix that. What is gadget will do is waste a lot of precious energy gyro balancing that thing. Energy that is not available for travel. And when the batteries finally puke, well, hope you love pushing the thing. A conventional scooter (or electric assist bicycle) can be kicked or pedaled back to home. One of the best scooters on the market is the Currie Phat Flyer SE. It weighs about 40 lbs, folds up, has a range of about 12 miles (not exaggerated mileage like the IT), can have its range doubled with a battery option and handles like a dream. It will run slowly enough to walk beside and yet do up to 20 mph. There is an optional seat and basket if you like. Cost is about $399 on sale, list is about $500. I've put over 500 miles on my Currie in the last 6 months. I recommend an online dealer, http://www.powerassist.com, located in Warner Robbins, Ga. Larry's a cool guy and nice to deal with. Another good one if you want three wheels but don't want a geezer scooter is the City Shuttle. Not as fast as the Flyer but more stable. It has a unique feature in that the rear wheels are spring mounted to the chassis which allows the chassis to lean into a turn. For half of what this IT thing is SUPPOSED to cost if he ever actually makes any, one can have an eGo, a street-legal licensable electric moped. 20 mph speed, 20+ mile range (verified independently on a dyno), comfortable seating and large wheels. My scooters have changed my life, particularly when RVing. I no longer have to worry about parking right next to the shower house in the RV park. I can park anywhere and just scoot there. And when we go shopping, I can hop on the scooter and hit all the stores in a mall without having to walk, something I can't do much of because of my knees. At the racetrack I can actually move around and see things again. Wifey has one so we can travel together. I fabricated a little bracket that mounts on the MH bumper and can hold up to 3 scooter (if a guest is along). I live in downtown Cleveland so I do most of my running around on the scooter. I seldom buy gas for my car more often than once every 6 weeks or so. Deano wrote: > > Have my fellow RV'ers checked out the new IT (Segway) motorized > "Human Transporter"?

Don, I'd normally ignore idiots like you - your comments demonstrate you don't know anything about PEVs, something that obviously didn't keep you from posting - but this gives me an opportunity to define usefulness. It is generally regarded (note for idiots: by those who use and sell 'em and who get together to talk about 'em) that a range of 12 miles on level ground is the threshold for usability. This provides a 6 mile radius plus sufficient reserve to handle hills on shorter trips. The holy grail is generally considered to be sufficient energy to go 20 miles at 20 mph on level ground. With available battery and motor technology, we're not quite there yet but we're close. Most folks find that a trip of much more than 10 miles at a time becomes quite tedious on a stand-up vehicle with little or no suspension. Which brings up the next parameter. It is generally thought that a scooter should weigh 40 lbs or less. This is because most people can lift 40 lbs up over door thresholds, steps and car trunks and the like. Heavier scooters are out there (My Badsey Hot Scoot weighs about 60 lbs, for example) but they are niche products. Given the above parameters, the final factor is cost. The market has said that it wants a scooter that costs less than $400. Recently a large Currie distributor went bankrupt and their large inventory was dumped on the market. Various on-line dealers experimented with different prices and packages, ranging from about $175 to $400. The $175 scooters lept off the shelves. The $250 scooters sold only a bit slower. The knee of the curve seems to be around the $400 mark. Certainly there are more expensive scooters that sell - Badsey makes a hotrod unit that sells for $3000 - but the bread'n'butter sales are in the $400 and under range.

The price is quite high for what you get. Currie stripped off the front brake, the nifty folding handlebar and the aluminum deck in that model. Unfortunately it is geared the same as their regular model, the Phat Flyer, which means that it has almost no hill-climbing ability. With a little shopping the regular Phat Flyer can be had for that price or less. I suggest contacting Larry at http://www.powerassist.com as a start. Back in the fall a major distributor went bankrupt and a whole bunch of 2001 Phat Flyers got tossed on the market. They were selling for $175 or less for awhile - I bought 4 of 'em. I'm still seeing prices in the ~$250 range. Retail is about $500. IMHO, the Phat Flyer and Phat Flyer SE (slightly larger frame tubes and slightly stronger motor) are the best scooters in the sub $1000 market segment. I find the scooter to adequately handle even my 295 lb weight. If Larry can't help you, simply search the web for Phat Flyer. Many other dealers out there. Unfortunately currie has not updated their web site in years so it will be of no help. John, scooter nut

So get your facts together. OK, let's talk facts. You're peddling a cheap chinese knockoff just like half the sleezebag flea market dealers in the world are doing right now, the chinese having literally flooded the market with the things. Seems like every other dealer along the "thousand mile yard sale" on Hwy 127 last weekend had those things on display. Most aren't silly enough to slap an "extreme" label on the product. I'm sure you can con some folks who don't know much about scooters into buying this tripe but you won't get away with it here. Facts: You're claiming to have a blazing 350 watt motor on the thing. Wow. Unfortunately for you, I've had one of these scooters in my very well equipped lab, a lab that includes a motor dynamometer. I've had a couple of those motors on the dyno and on my bench disassembled. Your blazing 350 watt motor really is blazing, as over 200 of those watts go up in heat, with only about 100 watts make it to the output shaft. Until I tested one of those motors I didn't know that a motor could be designed with such inefficiency! Then let's talk about the batteries. Of the several scooters I've examined, none had the same brand, all strange chinese no-names. In common, all had high internal impedance. (If you don't know what a battery impedance meter is you should learn, being the high, upstanding scooter dealer you claim to be and all.) None could sustain even a 30 amp discharge rate for more than a few seconds. Even conventional non-high-discharge-rated gelled electrolyte batteries made by reputable companies in the 17AH rating class can do that for many times longer. A true high discharge rated battery like the Hawker Genesis series can sustain over 80 amps continuous and do so until fully discharged. Perhaps we should discuss the controller. A tiny epoxy potted box (probably they're ashamed of the electronic design) about the size of a cigarette pack and wired with 14 gauge wire, as is the rest of the circuit. About as much energy is expended heating the wiring as driving the motor. The controller would output a mighty 15 amps into a locked rotor motor. Wow. My Badsey scooter controller, with a 1 kw nominal motor will peak at over 300 amps. That kind of current is necessary to accelerate an adult up a moderate hill. To compound the under-powered controller woes, it has an intolerable over 3/4 second delay built in to the throttle. Turns smooth riding into a guessing game. Forget blipping the throttle so those mighty 350 watts can ease the front end over a bump. For anyone unfortunate to have bought one of these things, the delay can be removed by removing a capacitor after digging out some epoxy. I can post a photo if anyone is interested. Then we could talk about the "charge meter" LED bar graph that is purported to show battery charge. Unfortunately, because of the tiny wiring, the voltage drop is so high that the gauge drops to 1 or 2 bars when the throttle is opened even on fresh batteries. >Oh yeah! how is your Currie scooter site going? Sorry Bud. No Currie web site. I'm in the BBQ and neon business, along with a little engineering consulting on the side. I am, however, an e-scooter enthusiast. The Currie is simply the best sub-$500 scooter on the market. For $499 retail, one can get real suspension on both ends, a >1kw motor, quality batteries and a US manufacturer (the frames are made in Thailand, the motors in the US by MAC, a defense supplier.) If someone wants a 3 wheel scooter but doesn't want the bulk, clumsiness or expense of a handicap scooter, I recommend the City Shuttle. It has a 750 watt motor, quality batteries in a removable pack and is articulated so that it leans into turns like a 2-wheeler. Unfortunately the chinese have knocked off this one too, equipping it with this same 250 or 350 watt motor (depending on whose lie you believe) plus crap for build quality and the same crap batteries. The real City Shuttle is built in Taiwan, has an aluminum frame instead of the steel of the knockoff, has a regenerative braking motor controller and weighs only about 40 lbs with the battery pack removed - light enough to lift into a car trunk. A key indication of a chinese knockoff is that the battery pack is not removable. The real Shuttle should retail in the $900 range. If you'd like for me to go on I can. I can post a spreadsheet to my web site that will allow anyone to use simple physics to compute how much power it takes to propel a given mass to a given speed. This spreadsheet will show your speed claims to be a flat-out lie. I could also post some numbers I have generated by my radar gun to back up the spreadsheet calcs. I could also write about the brakes on your scooter. How the backing plate and cable are so flexible that they must be adjusted to drag before any appreciable braking force can be generated. And how the scooter has no front brake, a serious safety hazard since over 90% of the braking on a 2 wheel vehicle is done by the front brake. Or I could write about the tipsy handling of this thing, caused by all the vehicle mass being above the axle centerlines. Having the floorboard that high defeats one of the major features of an e-scooter - being able to step on and off and to put a foot down in comfort and without having to bend the knees very much. Bad knees are a feature of the older types you're trying to peddle to, after all. I suppose I could write a little article about my personal Currie, equipped with dual 1kw brushless DC motors and 2 parallel battery sets. That's what it takes to propel my 285 lbs plus a 60 lb scooter to 18 mph AND be able to climb moderate grades. And the 8" disc brake up front, necessary to provide enough braking force to bring the front wheel to the threshold of lockup in a panic stop. Your Play, Burk, AKA spammer. What other facts would you like to discuss? ---- FWIW to anyone else reading this, I recently bought my 78 year old mom a City Shuttle and she loves it! She covered several miles along the Hwy 127 1000 mile yard sale last weekend, something that would have been impossible otherwise. We'd park at some convenient place and then scooter to all the booths within a couple of miles of the MH. I could probably have sold a hundred of either scooter had I been in the business.

However, considering that you can probably run faster than these things will go on any sort of grade, dragging your feet would probably do. My Badsey has no front brake, something I've flamed them about fairly severely. Given that it can do 50+ with the governor bypassed, that is a serious omission. John

Sam's has a low power Schwinn labeled Currie for under $200. It has a 500 watt motor. Adequate for gentle grades and normal size people. For larger people, the high end F18 the ticket. You may have to replace the wheels with cast aluminum mags from http://www.evdeals.com. Good place to buy the Currie. Scott's an honest guy. For the person who wants the ultimate, http://www.gobigscooters.com/ The 400 amp one is simply awesome. I'm on the waiting list for one. For three wheel scooters, the City Shuttle is the best. This is one that the chinese have knocked off so one must be careful. The real city Shuttle is made in Tawain, has an aluminum frame, has a 1 hp motor, has a lift-out battery tray, has regenerative braking and has a funnel shaped headlight. The price will be in the $800 range. The knockoffs have as small as 200 watt motors, non-lift out batteries, no regenerative braking and a steel frame. The headlight is somewhat bullet shaped. Here's a photo of my knockoff Shuttle and my latest project, a tiny trailer:
This is set up for car show tramping, with the large external battery and the trailer. I bought the knockoff because I intended on redesigning several aspects. I sold my TIG outfit recently and so needed the steel construction for weldibility. I've rebuilt the drivetrain with a high power motor and controller, more powerful than the real City Shuttle, and Hawker batteries (accept nothing less). I can either leave the external battery where it is or carry it on the trailer. I built this trailer last night and am waiting on the paint to dry. When it does I'll mount some of that perforated angle on each side for the bungee cords to attach to. I'll also apply anti-skid tape to the surface. This trailer was built using two 8 ft sticks of that perf angle, a sheet of thin plywood, a pair of cart wheels from Northern Tools, a 1/2" aluminum axle and a 1/2" steel tubing tongue with a clevis hitch on the end. Everything except the wheels came from Lowe's. The front of the trailer where the tongue attaches contains a piece of case hardened angle that serves as a torsion spring. The tongue tubing is also case-hardened. If case hardening isn't available then use a somewhat larger diameter tube. The wheels are held on with hairpin clips. The trailer can be disassembled in minutes into a very compact stack that will fit in any trunk or compartment. One word of warning. There has been a flood of very cheap chinese scooters hit the market in the last year. Everyone from Flying J to the pawn shops are selling them. That spammer who hits this group every so often sells them. They are absolute junk. The motor is as small as 200 watts and generates mostly heat. The controller can't drive the motor to full power. The wiring is 14 and 16 ga wire. The SLAs are junk that will barely survive 50 cycles at the high discharge rate a scooter requires. The wheels are very thin cast aluminum and break easily. You might want to spend some time on the evdeals website. Scott actually dyno tests every scooter he can get his hands on. He demonstrates the chicom version of specsmanship, eg, lying. He carries a nice line of products including the Curries. Feel free to ask any other questions. For me the electric scooter is my day in and day out transportation. I live in the back of my restaurant and am within a couple of miles of most places I need to go. I only use the car for out of town trips and when it's raining. I have put hundreds of miles on my scooters and so know what the weak points are. I'm not one of those blinded by green light, wild-eyed econazis so I won't hype EV BS. LEVs have their places in the scheme of things but they won't replace fuel-driven vehicles any time soon, if ever. John

However some thoughts. A 600 watt motor will not maintain 17 mph on a significant grade with a 200 lb rider. I have a spreadsheet that I can calculate the exact data but I know from experience about this. I have a total of 1000 watts of power on my Currie using very efficient brushless DC motors. I can maintain about 12 mph on a 4% grade. I weight 285 lbs so I'm larger than most folks. Give it a couple more MPH for someone in the 200-250 lb range. I do not like cog belt drives. Cog belts don't last long when exposed to road dirt and gravel. One of the common complaints is that a gravel under the belt will pop it off. My Badsey (junk) uses a cog belt and I have that problem fairly frequently. Like my Badsey, this scooter's rear sprocket is almost the same diameter as the tire, placing it down in the dirt, so to speak. Chain drives make a tiny bit more noise but last forever. The motor mount really sucks. The entire motor mass is cantilevered off the front flange. Badsey made the same foolish design mistake. The badsey flange breaks off on the first good bump. This motor's flange is steel instead of aluminum but all that means is it'll take awhile longer to fatigue. This scooter is worse than the Badsey because the motor is mounted on the swingarm and is subjected to wheel shock. This bad design has made for a nice aftermarket for folks like me and Scott at EVdeals.com to make better motor mounts. Here's Scott's: http://tinyurl.com/wfp9 From the photos I can't really tell whether such a mount could be made for this scooter. I can't rationalize the claimed weight with the battery capacity. If it really does weigh only 68 lbs, then the rest of the scooter has to be VERY light indeed. I think the range claim is a bit extravagant. With the claimed battery capacity and speed I don't think it will do it. That range probably is possible if the speed is held down to the most efficient, usually around 10 mph. I hate drum brakes. Bicycle disc brakes are so cheap and work so well that I just can't see the justification. The price is IMHO, bordering on outrageous. I don't like plastic/fiberglass bodies. They fairly quickly get scuffed and add little functionality. On the positive side: Nice looking Nice wheels. The look somewhat stronger than the ones we're using on Curries. Good tires - the Kendas are what I use. Free wheeling - extends range by not forcing the motor to turn when coasting. Lift-out battery pack. Very nice. Keylock. Helps cut down on the theft potential. Here's a dealer with a good reputation that provides some good info on the scooter: http://www.nycewheels.com/vesx600elsc.html Here is Scott's dyno test of that scooter: http://www.evdeals.com/DynoData.htm/VegoSX600.htm I personally would not buy another scooter with a belt drive and I'd shy away from drum brakes and polymer bodies for the above reasons. And I'd not pay that much money for low speed scooter. My standards are fairly high, since I know what I can do with available components. This looks to be a competent scooter but it is overpriced, IMHO. I still think the Currie line is the best bang for the buck in the sub-$600 range. John

The rule of thumb used in e-bicycle circles is the average human can make a half HP on a long term basis.

That's a hard number to quote because I make battery arrangements according to what I'm doing. I only use the 3 wheeler when I'm forced to. Some car shows won't allow in 2 wheel scooters even with a handicap placards. They MUST allow in the 3 wheelers so that's what I take. The three wheeler does have the advantage of allowing you to just step off and not have to put down a kick stand. I much prefer the Currie. Much more maneuverable and powerful and can pull the same trailer. I need to get up a picture of my Currie. I've added a second motor and a second battery pack. At 10 mph I can get perhaps 15 miles out of this setup on level ground. Wide open (currently geared for 18 mph and good hill climbing) perhaps 8. Lots of starting and stopping, such as at shows, much less. > >I go to Oshkosh every summer for the Experimental Aircraft Association >convention and airshow, and this place is huge (if you have any interest at >all in aviation, *go*!

Yeah, I really want to go to the Fly In. Maybe next year. For large events like that where you'll be stopping and starting frequently and idling along at walking speed, you have to make some provisions for extra power. In my case, that is a combination of removable battery packs, extra batteries, a quick charger and portable generator. The extra battery is appropriate for when you'll be traveling a moderate distance from your SBO (scooter base of operations :-) and you know there will be no shore power available. removable packs are for when you can branch out from your SBO in a daisy pattern, returning to change packs as needed. You can recharge the packs with your generator or shore power. You can carry an extra removable pack just in case. For long distances where it is unlikely you can get back to the SBO or find shore power, a cordless battery charger is appropriate. There are two approaches. One involves a quick charger and the smallest conventional generator you can find, carried on the trailer. My solution was to buy one of those tiny little 2-stroke chicom 300 watt inverter generators that Harbor Freight was selling last year. The whole thing weighs under 12 lbs. I removed the inverter and rewound the stator to generate about 30 volts at full throttle. It'll do 10 amps at that voltage which will charge a set of 17 ah batteries in about 2 hours. Or top 'em off in a few minutes. Or supply cruise power indefinitely. I also HIGHLY recommend a quick charger. Soneil makes a very good, if a bit expensive, switchmode quick charger. The charger is smart so you can charge at up to about 1.5C if the weather isn't too hot. The charger is physically very small. When you're in a place with widespread power availability, such as a fairground or expo center, you can stop frequently, plug in and top off while looking at things in the area. That's the way I do the Georgia state fair each year. The fairgrounds are almost a mile and a half long. I can go all day running back and forth and another half mile back to the RV using the quick charger. There are 120vac outlets everywhere. This also works in cities and is known in scooterdom as "leeching". Outlets installed for illuminated signs and the like are great leech locations. Easy to leech at Wallyworld and the like by pushing the scooter inside, asking the door guard to keep an eye on it and plugging it in where they charge the handicap scooters. A couple of years ago the subject of leeching ethics came up on a mailing list. It quickly devolved into the sort of "discussion" that pollutes this group. I did some measurements and computations and found that it take about 3 cents' worth of electricity to completely charge my Currie's batteries at the local rate. I just can't get cranked over that. I do try to buy something from wherever I leech but that's about it. One other comment. The 3 three wheel scooter is superior to geezer scooters in most applications where the rider can walk and has balance, even if only a little. It is cheaper, lighter (my Shuttle weighs about 40 lbs with the pack out), much more nimble (the Shuttle leans in turns) and much faster than the heavily regulated geezer scooters. My mom, who has emphasema, has a Shuttle. She's not capable of walking much more than to the mailbox and back. She enthusiastically rides her Shuttle. The extra speed (about 18mph at her weight) really makes a difference even when traveling the short distance between the parking lot and a store. I had a hard time convincing her that spending $400 out of pocket was a better solution than insurance paid geezer scooter she almost bought. Now she'd never go back. John

The market hasn't yet hit a critical mass so the dealers and even manufacturers are tiny, hang on by threads and come and go all the time. the story I got on the Shuttle from a dealer in the midwest was that the major importer had quit importing the real shuttle because of the cost. I have heard that someone else picked it up but I haven't looked too hard to find the info. I'm going to try to run into a major dealer while in Daytona this year. he had a boatload of real Shuttles last year. Maybe he'll have some this year or will know where to get them. I'm giving very serious thought about putting together a retrofit kit that will bring the knockoffs up to the standard of the original. This would include a more powerful motor and controller and some sort of removable battery pack. That would bring the cost back up about that of the real Shuttle but it would be worth it for people who actually use their scooters. John

Hi Harry, I've been using electric scooters for in-town commuting for >5 years now. I own several and have owned several more. This is my current one: http://www.gobigscooters.com/spec400.htm This is the biggest and baddest electric scooter out there right now. It is also the only one I've had that could reliably handle my weight (265 now, 130 lbs more a couple of years ago) I have done a few things to make it even more powerful. Better wiring and a more powerful controller, to name two. I've had this scooter for about 3 years and have put several thousand miles on it without any significant problems. I carry this one in my motorhome by simply wheelie'ing the front wheel into the door and then lifting the back end up. It fits perfectly. It will recharge either from the generator or my inverter. In the class scooter that the Zappy falls into, about the best one out there is the Currie/Schwinn F18. http://www.gobigscooters.com/spec400.htm Currie developed the design and licensed it to Schwinn. Sam's Club sells a down-powered version of the Schwinn that is a good value. The motor is a little weak for use in hilly terrain but it is useful for getting around an RV park or shopping center. Another good one in that class is the Great White http://www.evdeals.com/GreatWhite.htm Not as sophisticated as the F18 but not as costly either. The best in class and also the most expensive is the GoPed ESR750ex. This is a sharp looking and running scooter. It has enough range and power to be useful and yet can be lifted by one person. http://www.evdeals.com/ESR-750.htm Let me say here that the minimum power for an adult-ridden scooter is about 750 watts. The chinese junk in the 350 watt and lower class is just that - junk. A step up to street legal is the class of scooters roughly based on bicycle parts. Probably the best is this one: http://www.evdeals.com/e-GO.htm The eGo is very highly rated by everyone I know who has one. While street legal, I'd consider that status only for keeping the cops off yer tail. I would NOT go out and road warrior against the cars. The scooter just isn't fast enough. Handy for neighborhood roads and on bike lanes where permitted. The next step up are the Vespa-like Escooters. I'm not familiar enough with that class to advise. I rode a Currie Phat Flyer for several years and several thousand miles. A superb little scooter. The only problems I had related to my weight, which was far in excess of the scooter's rating. When I got the GoBig, I'd upgraded the Flyer to mag wheels, dual batteries, dual motors and disk brakes. Pretty much to the quality and features of the F18 out of the box. It was and is a surprisingly fast and nimble little scooter. Scott at evdeals.com is a good guy to buy from. Ornery and sometimes snippy but always honest. A rare commodity in the scooter biz, unfortunately. Oh yeah, I'd not take anything Zappy offered even if it were free. John

Not really. Mom's geezer scooter cost about $1200 from Sam's Club. A good 2 wheeled scooter will run $500 or more. The geezer scooters have many flaws. One is that many are limited to 5 mph. Easy enough to fix on hers by reprogramming the electronic controller. There is usually a large delay in the throttle response, again fixed by reprogramming. The small tires and low ground clearance catch on all sorts of outdoors obstacles. And, of course, they're clumsy. BTW, the only way Medicare or insurance will pay for a scooter is if the patient is incapable of moving INSIDE HIS HOUSE without assistance. If the patient can stand up on his hind hooves and walk, even with a walker, then he isn't eligible for government or insurance assistance. I spent a lot of time investigating this. At mom's insistence, I even talked to a couple of those outfits who advertise so heavily. The approach was the same, they'd refer her to one of a list of docs who would certify her as immobile. In other words, FRAUD. Regardless of whether the patient does it on his own or has the assistance of one of these scooter promoters, if one isn't practically bed-ridden, getting some doc to say so is fraud. All I would have had to do was say the word and to have hauled Mom to one of their patsy docs to get Medicaid to pay. I chose to investigate carefully and picked out a reasonably priced scooter with wheels large enough to be useful outdoors. She had tried one of the inexpensive 3 wheeled scooters and could not balance it adequately. > >The bans here are general cross-the-board rules that affects everyone >even though the stated goals was to "avoid problems caused by >irresponsible riding by minors" or some such verbage.

Imagine the horror of the 4 year old class at the local motocross track. They're actually racing against each other, usually with a parent running along side. Don't you agree that it's none of the government's business how a parent raises her kid? These knee-jerk bans happened in a lot of places, promoted, unfortunately by that Kamen guy who invented the Segway. He put enough money into the effort that he got laws passed in almost all states giving the Segway favorable treatment at the expense of all others. We (a loose alliance of scooter users on the Internet) have had pretty good success in getting these laws and rules overturned either by the political process or via the courts. The ADA is a powerful law to use against them if you have a handicap. There are some silly restrictions on Electronic personal assistive mobility devices (EPAMDs), what the ADA calls geezer scooters. These can mostly be worked around. But the big hammer is the "reasonable accommodation" provision. One can beat the petty fascists over the head with that one. Within very broad boundaries, the handicapped person can specify what reasonable accommodations he need. In my case, my blown knees qualify me under the Act. My reasonable accommodation is to use my electric scooter for personal transportation. I backed down the Georgia park service in a direct confrontation over the use of my scooter in state parks. They didn't want the lawsuit that I threatened. In another instance at the Daytona Speedway, they allegedly would not let in 2 wheeled scooters (though I photographed dozens in use inside the track) so I dashed out and got a set of training wheels from the nearby Toys R Us and mounted them so as not to touch the ground. After a very tense standoff with the head of security and with my finger on the speed-dial on my cellphone to my lawyer, they backed off. This one was especially offensive because my wife was in a foot cast and obviously handicapped and yet he told her she'd just have to walk. If I'd had a tape recorder, I'd have sued them till their balls turned blue! There has been no problem here in Cleveland. There are only a few scooters in town and we ride them conservatively. I've been stopped a couple of times but only because the cop wanted to find out more about my scooter and try it out and because he recognized my restaurant shirt :-) Pretty much anyone with age-related problems is protected under ADA. All it takes is some hard pushin' and shovin' to get the petty fascist bureaucrats out of the way. I'm hoping that one of the handicapped advocates will push a class action lawsuit against some state or city government that will set the precedent for the rest of us. I'm one of those folks who doesn't want anything from the government other than to be left alone. This is a perfect example of where leaving me alone works perfectly. John

Comments, links to schematics, or suggestions are >welcome! My experience with many years of working with electric scooters and bikes of various sizes is that regen isn't worth the effort and cost. It basically doesn't have any material effect. The vehicle/rider is too light to store much energy plus very little time is spent braking vs coasting or accelerating. A brushed motor is particularly bad because the brush timing is wrong for generating. Much of the energy is dissipated as heat in the motor because the brushes are shorting commutator bars that have voltage between them. Commutation should occur at the neutral field point when the voltage between the bars under the brush is zero. You will get much better results with an over-run clutch that free-wheels when the motor isn't powered. This lets the motor and gearbox (if present) stop turning, removing that drag. That's the approach Currie and then Schwinn take. John
