My 1964 Sears Allstate is needing a hub motor. With virtually no suspension or brakes I am not looking to break any speed records. My target is 40mph cruising, 45 max..
The problem I'm facing is motor rpm. The 16 inch wheels, which I want to keep, will require a 625 rpm motor (if i did the math right). I am not finding this. The closest match I've found is a qsmotor 3000w 205 50h v3. This motor will spin fast enough, but is way more motor than I want to put in the bike. I'm thinking a 2000w motor will be sufficient, if I can find one that will rev high enough.
I looked into putting a 1000w motor in each wheel. Again I ran into the rpm problem. I guess the motors I am looking at are used with larger wheels and lower speed goals.
You guys have bailed me out in the past. Any ideas will be appreciated.
Attached is a picture of the bike as I bought it. For $325 it came with a title and a Hodaka Wombat engine graphed in. I'm weak and couldn't say no.
