Special Project: The dual motor Catrike
Posted by David Elderton on 2017 Jul 27th
At Electrafest 2017 Vancouver. Justin from Grin testing the Dual Grin motor Catrike. Looks like there might eventually be a kit for this, possibly with quick release front motors! This trike as an absolute rocket, and very efficient. Dual hub motors are actually more efficient that a single it turns out. Even when pushed hard up steep hills at 50-60 km/h the motors stay below 55 degrees C. Easily out accelerates a 7 kW hub motor mountain bike. Dual Grin PhaseRunner controllers at 72 volts, 35 amps each
