Thanks d8veh, that was what I suspected going of ampage, motor size and reports.
I am looking at modifying one of my trikes into an offroader as I have an entire mountain of fire trails a short distance away but as I cant pedal with any force, I was going to fit a crank motor to it but it would need at least the power of the Tonaro even if I can get the gear inches into single digits, the trails are very steep.
