I just finished building an electric gokart for my wee one. Unfortunately I lost some pictures of the chassis/steering building. The donor was an Invacare Electra. These can be picked up pretty cheap on ebay.
RWD Transaxle ftw
Steering - pillow block bearing and a steering column & UJ from a Daewoo Musso.
Initial testing with all the electrics just strapped down, I was using the hand control arm for forward/reverse. At this point all the electrics were at the back. I later moved them to the front which meant extending the wires to the motor. This leaves the back clear for a boot and tow bar for a future trailer. Well you've got to be able to load up random rocks, sand & earth and move them to somewhere else, haven't you?
The scooter controls were housed in this plasic casing
I took this to bits and made a ply dashboard
I simply cut down the hand speed control arm and mounted it under the floor
Poking through
One of the connectors into the 'brain' was borked. A previous owner had tried to solder a new connection in but just melted everything. This was causing the scooter to randomly cut out, back when it was being used as a mobility scooter.
A motherboard connector cut down slotted in perfectly
Cable run underneath to the motor
IVA ready
Electrics tidied up and charging port sorted. The wheels are cheap pneumatic ebay jobbies (£20 for 4) and they have about a 30% larger circumference than the scooter wheels, so it goes a bit faster. The front hubs are just box steel with an M12 bolt welded through, the wheel then slides the bolt and it's tightened up. The rear wheels I had to change the PCD to match the scooters, as the scooter used keyed aluminium wheels (so I couldn't just weld the cheap steel wheels in place)
Ready to hit the road!*
