they go 30mph. Rob the one problem with those is the dia of the electric motors they use (they used 2 different versions) does not really match with anything one the market as of today. So if the motor turns out to be fried you have to do some modifying of the cradle that it fits in.
The electric system is very crude, throttle goes to a simple of/on/on switch 12v slow speed, 24v high speed. If you do some searching around there is some info where guys that are all about electric power have done conversions to them with updated electrics and motors.
There used to be a forum for them, a guy in Mass has a ton of them and bought up a bunch of there parts from old dealers etc.. but it all sort of faded away. You can still find wiring schematics and manuals online for them though I believe.
The bikes themselves are basically modified gemini's and a lot of the parts transferred over even off some of the Toyoco and Puma bikes too.
I had one, bought another off here and had the seller in CA send me everything but the frame as his chrome was better than mine etc.. had Kenny restuff the seat etc... but ended up chickening out on building it
hmy: Thats the only mini bike I ever lost money on:doah:
