Hop-Up Scooter LEDGEND Elete 1 Year Old

06/16/2011 11:08 PM

I Just Got A Near New Elete Scooter... 24 V. "2 12V.Deep Cycle" But Way to slow! How can i get it to do at least 2X Faster? (Now about 3 M.P.H.) My Old Rascle, would run circles around it! And goes 30x Farther on 1 Charge!

Maybe your Legend Elite scooter needs batteries 3x as large in terms of usable current and 30x in amp-hour capacity, plus a motor of 3x present torque and geared 2x as fast. Or something like that. Why replace the old Rascal?

Why Replace the old Rascle? I Parked it behind a car that came out of their drive way, with-out seeing it there. the Steering is Bad, after I Fixed it the best I Could!

On the battery Inprovement... I've been thinking of putting a Car Battery in with 1,000 C.C.A. Ive been told that the Deep Cycle will last longer, and the car bat. won't give any more power. But, I still want to try it. I Believe Adding 2 More Same Kind, Bat's,... Will make it last longer with-out any speed increese.

Bert, you can not get any more speed out of this scooter by putting "car batteries" in it, and you will damn sure not get any more range of use out of it, so don't waste your time or money. This scooter is designed to run off of a pair of 12V deep-cycle batteries. AGM or Gel batteries are the preferred, but marine non-sealed batteries will work if you want to go through the weekly checks on fluid, etc. AGM's are cheaper than Gel, and will work well with the scooter, but not as long of a useful life. Also, when they go out, they go out fast, instead of a slow death by the Gel batteries.

The batteries you have in it are probably shot, and need to be replaced. This is the case with most used scooter or power-chair purchases...see sulfating, etc. from storage and lack of use.

You can use a hand-held programmer to insure that the controller is set to 100% output in order to provide maximum speed. These are available through the dealer. If it is set at max speed, then the only way to get more speed, on the cheap, is to customize the scooter with much bigger tires, and cutting the shroud away to accommodate same.

The regenerative braking system is not a "governor" or speed-limiter at all, ever. The speed is governed by the controller, period. The brakes only go into a braking mode when the scooter is in motion and the throttle lever is let off, or if the scooter is on an incline where the top speed is noticed by the controller, and auto-braking is activated so that you won't roll down a steep incline at 40 mph.

If you still want hop it up, then you will have to go with a 4-pole motor instead of 2-pole, and find one that will match up with the transaxle assembly. Good luck with that.

In short, if you want a fast mobility scooter, better to but one that is designed to go 8+mph from the get-go.

THANK YOU...{ Hapy Fathers Day Week End...} I have another Elete... But the controler is Dead, I've been told. It's older and may be tough to get replacement parts for. ( My Rascle use to run circles around it.) But the Rascle has Smaller Tires...

Which makes me wonder if the bigger tires may slow the motor more than the smaller tires, at more rate than the advantage the circumfrance is. ( I'm sure the motors are different too.) [ SAME BATTERIES!] Gell. The one with the bad Controler, will be my Experamental Scoot. I'm thinking of Dirrect wireing... With a REASTATE for throttle...

I Know--- "Keep all Gas Cans Away"!!!

If I Wired it up as 36 Volts, would that be any help? ( 3 Batteries)

Definitely don't do this. A rheostat used as a throttle will reduce efficiency but will also disable safety features.

Be aware that scooter batteries can explode if shorted with a dropped tool, you can get burned, etc. so don't do the tests mentioned below unless you are qualified.

Your scooter should do almost 6 mph, and almost certainly did when brand new. After you have charged the batteries overnight, let the scoot sit for about 5 hours, and then measure battery voltage, individually. If either is less that 12.6 volts, then one or both batteries are shot.


The dramatically reduced range suggests the the batteries are shot as well.


If the batteries are both 12.6-12.7 volts (after being off charge for several hours) then the controller is malfunctioning (or you have not set the maximum speed correctly).


About 4 months of sitting around unused is enough to sulfate many batteries, making them useless. But don't jump to conclusions: test. With all reputable brands of scooters the tire sizes, gear ratios, etc are engineered in, so the gear ratio is changed to yield the design top speed, as required.


Controllers on modern scooters are all pretty similar, (and all are fairly efficient -- over 90%) So typically, reputable scooters perform about the same. If yours is really only going 3 mpg (typical pedestrian walking speed) and has only 4 mile range, your unit is malfunctioning, and in need of repair, not modification.

Putting larger drive tires on the scooter will not slow it down. The motor shaft rpm is constant, regardless of the tire size. Because Larger diameter tires cover more distance at a constant rpm than smaller tires. You will not have the acceleration that you have with the smaller tires, but the high-end speed will increase.

Do not increase the voltage to the controller. It is at a maximum amperage level now, and bumping the voltage up will fry your entire system. Do not use a rheostat to control the amperage. You will lose the automatic braking system and other safety features built-in to the controller.

Zap makes a sit-down three-wheel scooter that goes for about $700.00 if you are looking for speed and distance and can manage to control the braking manually. These are 36vdc systems and use a GB motor in the front drive for propulsion.

Here's one of many sites that sells them. http://urbanscooters.com/cgi-bin/urbanscooters/Zappy_3_Pro_Jr.html

Note that they are lacking in suspension of any kind, so urban drivers pay heed to cracks and dips in sidewalks/streets, railroad tracks etc.

Bert, which one do you have?

This model Legend scooter has a listed top speed of 5.75 mph. This is interesting: as a speed governor it uses regenerative braking, controlled by a processor. If this is the one you have, it looks like it will be difficult to "Hop it up". But you should be able to get more than three miles per hour out of it. The manual also says the range should be about 16 miles... will your Rascal really go 480 miles on a charge?

The "3" Wheeler... 5.75 M.P.H.? It is real close to wakling speed. I cross the intersection about the same as the pedestrens. My Rascle would be accress the street. while the ped's would be 1/2 way. I have been told to slow it down in markets, when it is safe to move at full speed!

If you put a chainring, a set of crankarms and pedals on that thing, you could easily triple the speed while putting no more drain on the existing battery.

I've cross the entire country twice with a similarly configured vehicle, except mine didn't have the motor nor battery - and I often got over 5 times that speed, once even got 20x it! (yes, 60+mph on a bicycle)

I remember a long time ago the bicycle record was 106 m.p.h. ( between railroad tracks) with 20' wind guards "making a vacuum" By a train in front.
