Got the heavy duty bearing, I'm my previous china girl build I learned the hard way about overstressing the bearing, went through like 3. I actually have seen this video seems nice, I really am trying to simplify the transmission want the least amount of gears to have to deal with shifting through. Probably not too ideal since I live on a mountain it's down the hill to the store but back up the hill home, really don't wanna pedal uphill. I guess what I'm hoping for is minimal gears with a wide range, which I'm sure is asking for too muchI like to include in that math a range between engine and crankset that matches close enough 60rpm cadence to mid-motor RPM.
I enjoy boosting speed. My test up the most challenging street hill so far was the only hill I HAVE to help. Even then, I'd boost it above mid rpm, rest a bit while it slowly sagged, do it again, and it did well, I did too.
Its alwayz good to keep Plan B in shape. Case you run out of battery, or gas, done both recently, yeah I was dumb. But tough too.
