The reason I am not able to mount the motor on the rear is the same problem as mounting on the front left side drive. The motor is too large! It hangs over too much on the left side, so the left side pedal will make my foot hit the motor. The only place to mount it is aft of the rear triangle in front of the drive wheel. So I will have to make the rear extension several inches longer, at least 5 inches.
Mounting on the front has the same problem. I would need custom brackets to hold the motor out away from the crank. So maybe later when I get a round-tuit I can actually build something.
If any one wants to use this motor for a cargo bike, they should just start with a long-tail bike that has room behind the seat post. Back far enough or up high enough to clear the left foot.
I wish I could start over from scratch, I would start with the Bafang BBSHD or what ever it is, that can draw up to 2000w.
Yes I do want to build the most heavy-duty cycletruck that has ever been built (except for 'staton-inc'). My neighbor built this heavy-duty velomobile frame, but he did not build a way to haul cargo on it. But he had the right idea about how to build a really strong frame.
I also think that a rim pulley could work good if I were to build epoxy teeth for a timing belt. Not that it would be easy. And yes a timing belt may not be strong enough, I have not looked at how strong they are. So a chain maybe the most affordable.
Gates belts are so expensive I think they my not last long enough for the price??
But if my wheel brakes because the gear reduction is so low that the wheel just cannot handle the abuse, I will have to rebuild it in a much stronger way. And yes a lager sprocket may be easier, but only if I can find a wide enough hub to make it all fit correctly. I won't fix it till it brakes, but I gotta know where to start if it does.
What are the “parameter settings on the programmable controller” that you use?
This motor spitz out too much power, how can I tame it with the controller??
I was about to buy the battery pack but they are out of the one I want. Only 13.5Ah because I finally calculated that I need only half of that even at an 80% charge. 8 Mile round trip maximum at 30Wh per mile= approximately 140wh needed. 648Wh – 20%=518wh but I keep getting the crazy feeling that I should buy more.
11.5ah x 52v=598wh -20%=478.4wh or 13.5 x 52702 -20%= 561.6wh No point in tempting fate by giving it more power.
