Hello. I'm working with a group of 8 kids at the school I teach at to build a HW for the next season. Lots of progress so far, but I'm struggling to know what drive motors to buy. We designed for NPC T64 motors, but with only £400 left they're out of the question. I've been looking at the electric bike motors below. They look cheap and pretty sketchy, but do you think they may work? 450W and 450RPM with 10" wheels, I made it just over 13mph. If they don't work could you make some suggestions??

Thanks in advance. Dan
