Re: Bikes compatible with Bafang BBS02 motor

BTW how many BBSxx kits have you sold? Sold? None. Installed? More than I can recall. Never had to turn one away because it wouldn't fit. Also, I've worked on more different bike brands and models than would ever make it onto your hypothetical list. Skykomish? Hujsak? Jupiter Beat? Texas Rangerette...

Re: Bikes compatible with Bafang BBS02 motor

WTF do you insist on making it difficult. It's not difficult! Bafang has made it as easy as they can, and most bikes work fine. But trying to sort by brand and model is insane. You look for a normal threaded BB shell and a down tube that slopes up instead of doing style-driven monkey business. That...

Re: Bikes compatible with Bafang BBS02 motor

Dude. There are a jillion friggin' bikes out there at any given time, and the same model from the same brand can change substantially from one model year to the next. There is no way you or anybody else is going to make a list of will-do or won't-do models. You can only figure out what features will...

Any cell that you have to use massively parallel to get what you need, is silly kid stuff. You don't have Tesla's process control or their manufacturing robots. 1P is the best P.

By hobby cells Chalo is referring to smaller RC (hobby cells) lithium polymer pouch cells NOT 1865s or 2170s. 18650s are absolutely hobby cells. You can get hobby welders and hobby cell holders for them, fer cripes' sake. Building batteries with them constitutes a hobby in itself. By EV cells, I me...

Re: Any reason to not go Straight for a 14s, 52v pack for my first battery?

As for why I was looking at them so hard? Because they're $5 each, Chalo uses them in his bike powering a leafbike motor, The ones I'm using are not 5Ah, but 25Ah (original rating). They're also rated for 300A discharge, which I'm not asking them to do. EV cells are a different game than hobby cell...

Re: New "TSDZ2 Torque Sensor Central Motor"

Do y'all drive a car or a real motorcycle? If so, does it have a power interlock with the brakes? If not, how do you possibly manage it? Yes, it's called a clutch. If you don't engage it (for a manual/stick shift) when braking to a stop the engine will stall - which is analogous to stripping the bl...

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.

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...

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.

Leaf motor is a great choice because he can get 11t w...
