Can someone guide me. I live on a remote place and no one has 24 inch rims. My ebike is a Giant DH comp with a rear hub in a 24inch wheel. I want the change the front one to a 24inch. It needs a 20mm hub. My fork is the stock Manitou that came with the bike. I can buy the wheel and spoke on...

You need a better bike and a better battery. Buy a downhill bike off Kijiji Build a 72v 14ah battery Install your motor and controller Ride between 45-65km/h for 20 km Recharge

I am running my BPM code 11 at 20s 25amp with no problem at all.

Here's the correct wiring diagram, Leo sent me.

Received and installed greentime 72v 45a 15fet controller today. There were no instructions or diagram with the controller so thanks for this thread without it I would still be trying a bunch of combinations. Tried it on my em3ev dd motor and was really surprise! I've hit 70kph (43mph) without...
