There was an earlier thread on asking about motors to fit a particular bike. My question is finding a bike to fit a particular motor. I have a BMC V2-T hub motor on a 20" front wheel with a 36V battery pack. It is the perfect motor for my application - it has no drag, and climbs the hills I need to climb, and has a perfectly adequate top speed of about 15mph.
I want to find a bike with a decent gear range (a good 7 or 8 speed), that I can mount the motor, and swap out the crankset with my 115mm Isis crank (why a short crank is another story). I want to keep the price down. Weight is not a concern. A strong steel fork is required.
My first thought was getting a used kids bike and getting a long seat post and stem (not as easy as it sounds). This is still an option, but a folder is already set up for adults (I'm 5'9") and might have a longer wheelbase than a kids bike. So I am looking around for a folder that would work. Giant Expressway I, Downtube Nova, and Citizen Miami look good on paper.
I would like to hear what you think about my approach.
