As picture above but with off road tyres.
My plan is to take a stock 48v brushless scooter and swap out or improve the drivetrain to make it a little faster but not too power hungry around 2700w, I will be using lipo cells at 20s 84v 16ah for a 1.3kw hour pack so should be good for around 30miles or a hour of blasting about up the mountain.
The parts I have so far are :-
Bidirectional shunt 120v 300A
44tooth sprocket for 4-1 gearing from 5-1
Stock motor will be rewound by myself to drop the kV
Sunwin 48-72v 1500w controller 18fet, 100v caps, the shunt is set to 58A and has bridgeable pads to set it for 84v and 4.6w max I've changed the connectors to a Xt90 (battery) and Mt60(Motor) jst (halls) I know there are more capable connectors but these are compact and more than capable of my design needs.

Battery normal 4.2v lipo cells,16s is the goal I want with a fairly eco motor to get a large distance i can travel but still good speed and light enough to carry up steps etc.
