My motorcycle uses an Alltrax 300 amp programmable "AXE" controller.

It is the 24-48V model. When I bought it, I was really split on if I should get the 24-48 or the 48-72V model. 48V has been good, but 72 would be even more fun.

300 amps has been plenty for me.

My cycle is designed for a 45 mph top speed, and uses about a 5 to 1 gear ratio (chain and sprockets) with an Etek motor. I could go with a faster (more amperage required) gear ratio, but that would also hurt acceleration, and I don't think the Etek would love it.

For something like a series wound motor to a driveshaft, higher voltage and amperage controller is probably a good idea.
