. Depends if you want regenerative braking, What motor to go for...

Could avoid using a gearbox perhaps... drive each wheel with its own motor

The Curtis controllers are quite programmable and you can define torque curve etc. A nice battery monitoring system would be on the cards to!
He has broken a driveshaft previously but not surprised with the torque it looks like it's putting out!
Really... i just want to be able to park at the front of Ikea to charge up lol
