Handlebar and motor connection
On our KnightKrawler, the window motors and both wheels are attached to a two 3/4 thich aluminum motormounts which are attached to the standing platform which has the battery box pop rivited to it and the handlebar mounting tube is attached to the battery box.
The question about the PVC throttle mechanism ...the throttle and turning twist grip control is done by slipping a second tube over the handle bar tube and containing it with a press fitted third section of tube. a bit of the handlebar tube is left sticking out to allow for precise control. when your hand is part on and partly off the twist tube you can more accurately control the input while you are trying to keep your balance. Of course if you have a dynamicaly balanced system that works well this will be less of an issue.
The potentiometer has a wheel attached with an "O"ring to touch
the twist tube....it doesn't touch directly though, it needs additional traction and we use bicycle grip tape to give a spongey
positive reaction to the pot. If you slip the potentiometer for any reason you will lose balance. You need to be sure that the pot is free to slip in cases of overturning or you will break the pot.
When it is all working right and the rider is experienced it is hard to tell that there is no gyro!
Need pictures?
