Good luck with your project. The E&C 150/300A recommendation is safe if you ride reasonably. After careful vernier caliper...

Evwan- the producer of that video, who is now I've heard deceased, was knowledgeable but known for being highly opinionated. My...

This topic is more interesting than I'd initially assessed. Accurately securing two bearings on a shaft in fixed housings/end caps in an...

Very astute observations as usual amberwolf. It's a not-great manufacturer shortcut. I suppose a stronger wave washer would be an...

This disassembled motor may be of interest to some. 2 days ago I noticed some .100 inch of axial end play in the shaft, which didn't...

Good observations by reneclaus11 in post #100. These inexpensive motors are under appreciated for basic single stage chain drive...

If these get to the $6 range for a hundred cells by next year I'll probably sell the 100 lightly used Samsung 50s I recently bought and...

Ok, watched the video, so it's already been done. I've done a lot of TIG, and am surprised that significant grease and oil didn't get...

I'd need to see the actual assembly in question, but this sounds like an idea I'd avoid. Welded parts must be scrupulously clean, you...

Finished. I now have #30 bearing units on 2 of my bikes, and no plans to build any more. Or more bikes at this point, as 5 is enough I...

As promised, working away at another unit with the heavier #30 bearing. The raw stock is pictured, and I bought an inexpensive single...

Voot- great that you have CNC. You'll keep us posted if you start building then. mx- thanks, that's about what I figured. It seemed...

I used recycled cells for my first pack build, and the results were fine, but I'll never hassle with that again. Way too much labor, and...

Thanks :). The white bike is light, compact, precise bmx handling, but no suspension. Max 42mph. The green OCC Stingray is...

VooteleAer- looks like a tall order to dive into a motor build like that unless you have CNC equipment. Even then daunting as a DIY...
