That's close to the initial idea i had with the mentioned motor (Aliexpress).
The problem with the motor you linked is that its gear reduced RPM is about 700, and it will be difficult to get the wheel speed you're looking for with a single stage of external reduction.

Re: Is buying a used Brooks saddle a good idea?

I'm looking at a 5303 but has a 48v controller with 4110 fets so sounds like a 72 v controller ?
5303 is a fast wind; it works much better with a lower voltage but lots of phase amps.

Re: Special 6-seater bike build

Looks to me like there's a gap between the frame and the wheel that could be used to fit a 48t (or whatever appropriate size) sprocket. Instead of a spacer, there could be a keyed carrier for a chainring. Yes, but then you would have to move the chainrings and chain to the outside of the frame. May...

There are plenty of options for Hailong, Polly, and probably other frame mounted hard case batteries that have a speed controller in the base rail. Topbikekit has a bunch of them.

Re: Special 6-seater bike build

The model is 1500W, freewheel rear version is probably best for what you're doing (because you can mount a sprocket on either the disc brake side or the freewheel side). But if you look at the picture, the freewheel is mounted on the axle inside the frame about 3 or 4 inches from the wheel. The whe...

If you only have two motors, well... you're going to need at least two wheels. I don't see the need to conjoin these twins.

Re: Special 6-seater bike build

Its easier and cheaper to limit power then it is to make more, higher power. I was going to say Leaf 1500w hub motor if you want two motors, or a single qs 3000w hub motor If all he wants is sub-5 mph, power isn't really the issue. It's gearing. Leaf motor is a great choice because he can get 11t w...

No, there is no list. Given the number of bikes available, that's like asking "is there a list of people who look good in these pants?" If your bike has a threaded bottom bracket shell and a straight down tube that slopes upward towards the fork, then it's overwhelmingly likely a BBS02 or ...

You don’t need brake sensors with a torque assist bike What's your rationale for that statement?
