3 speed pocket bike

[jamessparkman]

I have a Chinese pocket bike and Im quite impressed with its power and speed but i want to go a little bit faster and thought of putting gears on it. My plan was to get on old mountain bike use the derailleur and add 2 more gears. i have no idea if it would work just putting it out there for any suggestions.

good luck killing yourself.. the pinion would spin to fast for a derailer to connect it to a sprocket quickly enough.. i wouldnt trust it..

Hey you can always try but I think you'd snap the derailer from the torque of a pocket bike engine. Keep in mind power wise even a stock cag engine will do about 2500watts of power vs a human on a pedal push bike who can push about 200w - 400w constant i belive. It'd be suprised if it didn't snap.

and the chain on a pb is shorter and not made for any type of flex so it be worried about snapping the chain

yer good idear but if that chain snaps or comes off wile going that fast, it will catch on to the back gear and then you will swerve out of control happened to me to day only lucky me i was only going 10- 15 kmp/h i slammed on the brakes i think it was a rock i could of ended up in the you know what,

da thing i can't spell +

i guess you could hack in a motard gearbox. that would probably be as close as youd get
