That's a great use for those cheap e-bike kits on eBay and AliExpress. The motors are fairly torque-y. I wonder if the motor would be any good for a band saw? Or to drive a variable speed air compressor? I would love to have speed control on my big compressor. On-and-off pressure switch to maintain 150 PSI in the tank just so it can be regulated down at 100 PSI is completely stupid. This motor would be way too small for that particular compressor but maybe a different one.
