Control and drives
DC series exited motor
Curtis controller 72V 500A
curtis potbox for accelerator pedal
Monitoring instruments
BMS123 battery cell monitoring system

Driving
Helmet mandatory.Preferably on cross country race track or grass. Not for asphalt use because of the design of rear axle - no differential. The car cannot turn without one rear wheel slipping. Like in kart racing. Otherwise if there would be a differential the wehicle would spin one wheel on start and acceleration would suffer.
Maintenance
Brake pads
Suspension parts
Chain lubrication
every year check motor brush wear
Battery capacity check
