With regard to twisting torque, probably a better term, I’ve read several accounts of mid drive Bafang motors want to rotate if not mounted upside down on a Bacchetta and mated with a robust torque arm attached to the boom. I guess if the motor doesn’t want to rotate, why do you have a torque arm the size of a Texas mounted to the frame?

With regard to taking off the rear wheel, I’ve had the rear wheel off multiple times this summer for various reasons. I built the bike up from a frame, so I certainly Know how to disassemble it. There is no magic to removing a rear ebike wheel. You disconnect the motor cable. Release the torque arm from the chain stay. Use a box wrench to loosen the axle bolts and pull out the wheel. There are a couple spacers that you have to put in the right place and line up, but the nice thing about a Bacchetta is you just invert the bike on the grass and it stands up on the top of the seat back and handlebars so it is easy to remove the rear wheel. I guess I don’t understand why removing the rear hub motor wheel to change a flat would be any more difficult or time consuming than changing a regular bicycle wheel by myself.

I purchased my hub kit from ebikeling online because they are based in a Chicago and it is easy to reach the owner for answering questions. But again, I’m not going to suggest what motor you go with. I just wanted to refute the statement that a rear hub motor can have a bad effect on bike handling. My system below. Note that my bike has no chain or gears, but the kit comes with the typical cassette, etc like most ebike kits do. With regard to range, I said 20 to 25 mph range, but that’s probably more like 15 to 25 range across the use of a full discharge period. But I also don’t have to climb major hills. But that range is with throttle only.

Note that the purpose of this build is for getting around a winter retirement resort replacing the need for a golf cart that most seniors use or a second car. I don’t need to mix regular road cycling with riding this ebike for exercise. I have a very fast Carbon Aero that I ride a 100 plus miles a week with cycling groups. I have a regular e assist bike, but I found I was primarily using the throttle and didn’t like the seat comfort, so I built the electric bent in the photo. I have pedal power to the front wheel but it is single speed, so I can only pedal to 7 mph. The rear wheel would be no more difficult to remove with a chain and cassette. If you have your handlebars filled with gadgets that don’t allow you to flip over your bike, that is unfortunate. Flipping the bike has nothing to do with a rear hub motor wheel. You still have to change a regular rear wheel flat and being able to flip the bike makes changing a flat a whole lot easier.
