Smells like boondoggle to me. Like some recent engineering graduates haven't kept their eye on the ball of benefits needing to outweigh costs. "Free energy" isn't free if it bankrupts you getting to where you can use it.

BBSHD power through an 11t sprocket seems like a terrible mistake. Those things barely work with muscle power, and only do the job because they're called upon so infrequently. There are reasons that bikes with chains were ridden competitively for 100 years before people forgot engineering...

Cool, that's the best price I've seen yet. Thanks for the tip.

I'm saying that because the threaded axle end has the sole job of applying a constant tension preload, 14mm doesn't do that better than 10mm or 9.5mm. It's the stack of stuff from locknut to locknut (or shoulder to shoulder if the axle is monolithic) that matters for strength and stiffness. If...

Cool, thanks. I think I can find what I need with that information.

I didn't think you understand what the bike's axle stud does. The stack diameter matters; the axle stud is just a fastener. If you don't get that, you're way over your depth.

My work was just donated this motor taken off a piece of Aventon garbage. I can't even test it unless I come up with an adapter cable (or worse, amputate the plug and tease out all the wires). Google Lens is no help at all in this case. Does anybody here know what to call this ten pin plug...

Wow, can you even pedal that? My knees would strongly disagree with that wide a block of nonsense where they need to be.

Find out the continuous discharge rating for each of the batteries you're considering. I try to limit my maximum discharge current (dictated by the controller) to less than half of that rating, for the health and longevity of the battery. I also charge up to 85% and refrain from discharging...

Bosch is a trap for fools. Tongsheng is underengineered junk. Pick your poison, or decline poison.

Have you made a battery before, from cells that weren't fished out of the garbage? There might be safe ways to do what you're suggesting, but a n00b isn't going to nail it on the first try. If you must try this kind of salvage, I suggest starting with a solar charged led driveway light or...

Well they're using a 9 speed chain, so they left all the durability on the table. And they're using, from the look of it, an 8-9-10 speed freehub, which means they're giving away all the wheel strength benefits of narrowing the gear cluster and improving wheel dish. I think it's a gesture in...

That's okay, they more than make up for it by being soul-crushingly slow on uphills.

I ruthlessly delete switched brake levers on any e-bike I set up. Why in the world would I use something whose single function is to keep my bike from working? Also, why does a sub-1hp bike need this "safety feature" when nobody's grossly overpowered motorcycle or pickup truck kills the...

Nah, just submerge the whole bike in hot wax. If it's such a miracle on the chain, surely it's equally marvelous for all the bike's other moving parts, and will make the thing last forever.
