Hi, facinating forum!
I've been thinking for a while about making a bike with a motor to help with my daily commute which is about 15 miles. I'd like something which could get over 30mph if it could be achived.
I was thinking of using an Ampflow A28-400 DC motor (for its low rpm circa. 5000rpm) fixed to the downtube of a hardtail, mated to a flexible driveshaft that turns a bevel gear mounted where the rear brake rotor would usually be on your standard MTB.
The thing is, I'm no electronics expert (although keen to learn) and I see that the majority of 30mph plus e-bikes on here are running quite high voltage. The Ampflow motor isn't recommended to overvolted as far as I've read and that would limit me to 24 volts. With this type of set up would I have any chance of achieving my goals?
Also, is a motor controller strictly necessary with this type of motor? Or could it just be wired up in an on/off configuration directly from the batteries? (please be kind when answering this one!)
Any help much appreciated!
