The first dry dirt testing and what an awesome result..

The throttle curves and software settings were worked out and the results are in: 

Possibly the fastest electric off-road motorcycle on the planet!

This off road application demands peak currents that are twice that of the BMW peak current (because of the 10x voltage difference).  

The general design is scalable to any cell size and cell count to accommodate different motors/controllers, current and storage capacity.  

Two fresh CRF250R bikes…
