Interesting. I had a Black and Decker 48v. mower that has to be, lord, 15-20 years old. I felt really green about it when cordless electric was new... I changed the sla's once, and they were really reliable and powerful in that application. When I changed the batteries, I shorted out the bms. Leaving me with a lesson learned by literal fire, that we don't mess with battery shorts. In spite of that, and primitive wiring post battery change, things kept chugging along...

That motor was really substantial. It would cut through dense grass for an hour when the batteries were new. I'm sure that a smarter brain than mine could make a rad commuter out of that idle mower. I didn't want the expense of another battery change.

It can't be that great a leap. If my wheel was turning with similar torque to the mower blade, I'm in at least 6th heaven, and I get back 6 sq. ft. of my garage...oh, wait the surplus bike frame, too...Could it be possible to park a car in my garage? I just peed myself with joy.

My electric gokart/tractor uses an old electric mower motor. Very powerful brushed motors. The mower motors I have would be difficult to use in a bike, they are very long, but they would be suitable for a trike.
