Homemade light trial mid drive outrunner

Post by lefortbron » Mar 07 2020 8:05am

Hi

I am going to present my build, low speed high torque
Low center of gravity. Removable battery. No seat, not "catching the eye" design

Work is on progress, i have to weld footholds and some minor things.

I made tests with 24S battery 80A controller 200A phase, works good, a wheeling machine. Top speed around 40kmh without flux weakening.

I'm using a 9C motor RH212 Kv=10, i modify it with hollow axle. I have a torque arm linking the stator with the frame.

Work is still in progress, but I've already rode it.

This looks very well thought out lefortbron and a very functional Nd effective build. Nice work so far.

Cheers
Tyler
