Yes that does make sense.
I like the geared hub motor illustration also. If I were to get one for my chain drives would it give me lower gears for steep hills. Currie has the special wheel I paid $120 for and is already geared for 13.5 mph at 500 watts and 320 rpm@24V.
The 24" cargo bike is geared for 16.5 mph at 500 watts 1,500 rpm@24V.
Basically I don't have any use for a geared hub at this time but maybe if I go with a chain drive for the HaroV3 I will be looking for 40+ mph gearing so the top gear in a geared hub will be for 40 to 43 mph and 2,000 to 2,500 watts so if the geared hub can downshift to say 32 mph and 22 mph for the steep and steeper hills with the 2,000 to 2,500 watts then it would be worth having a geared hub with a shifter.
Please let me know. It would need to be a rear drive only not a dual motor so I would need the 2,700 watt Imperial electric motor and a 100 amp 48 volt brush controller and that could be a problem unless I get one with the pot. I really wanted a thumb throttle for that kind of power though. Anything OVER 36 volts and 750 watts I prefer a thumb throttle over a pot.
The pot. is great for pedal assist as you can set it for 10 to 15 mph and pedal if you have a pedal chain that is.
I am looking for pedal gears and derailleurs for all my e bikes except the dual motor bike. It is impossible for pedal with that set up.
I would need to remove the 80 tooth from the freewheel replace the 24 volt 500 watt motor with a 36V 800 watt motor like is on the front and 56 tooth spoke sprocket. The reason is the 24V motor on there now is 2,500 rpm @ 24 volts and the 36V motor is 1,834 rpm @ 24 volts and geared for about 20 mph at 500 watts with the 56 tooth.
It is why I am leaving the dual motor set up as is because it works and is great up hills at 24 volts. I do not need to run it at 36 volts as the Currie will do 28 mph with 48 volts or 6S LiPo. This is why I have come to a standstill concerning a new build. That and lack of $$$$$. Also lack of a brush controller good for 3 kilowatts and 100 amps.
The only build I can do for 40 mph and a thumb throttle is a dual motor set up with a 1,000 watt motor front and rear hooked to a single thumb throttle. I have one 48 volt 1,000 watt Chinese controller compatible with a three wire thumb throttle. I will need to order two motors , one controller and two 65 tooth spoke sprockets. That will cost too much $$$$$$$ Thanks.

Still looking for a dirt bike frame for the FX project. I was supposed to get welding equipment to try and copy the death bike but that did not happen either.
Maybe next year.
I could use the grinder on the wrench to reinforce the dropouts but chrome is slippery and not sure it would work but could grind it so it wont slip. I need a complete wrench set both SAE and metric anyway then use the extra ones I got and put one on the outside axle as well with the clamps also so it will be the same as expensive torque arms. What do you think. If it is workable I can probably do it within the next couple of days. Two wrench sets is cheaper than two torque arms and then I got complete sets of wrenches.
Please let me know.
I also have thick steel pieces and could make something stronger than standard torque arms with the grinder I think. I will have to see. Thanks.
