The putty has an advantage: it doesn’t shrink in hardening.
Regular JB Weld does not shrink either.

Re: gorilla glue epoxy/hall sensor

JBweld is good, but not any JBweld. High heat is the one you need. Any other brand of epoxy will do, as long as it is spec high heat. 3M #2214 and JBweld High Heat are best and easy to source. Regular JB Weld has pretty much the same temperature limit - 550 degrees F. It may even be slightly better...

Re: What makes a good commuter?

I'm surprised that you aren't closer to the times I estimated. I guess you probably have more traffic signals and stop signs than I have. I can average about 3.5 minutes per mile pretty easily on a pretty ordinary ebike.

But regardless, I think you'll continue to enjoy the routine. I still do.

Hi..I see black residue on a large yellow componant, not a capacitor though. Not sure if its worth fixing though. Snap a photo and post it.

True. But so far, Tesla batteries have been lasting 300,000 to 500,000 miles, so not a big difference there.
And may soon be lasting even longer.

If saving money is the goal, #1 rule is, only buy what you can afford, as in paying cash.

Re: 5v source on Kunteng controller

Also keep in mind that it is can be handy to have a nice, robust, 1-2 amp 5v power supply on your ebike to charge your phone and/or certain battery powered accessories such as lights. So the small investment (less than $20) might have benefits beyond your immediate need/concern.

I don't think I've ever felt grief as deeply as when we lost our Yorkie-poo, Sparkle, unexpectedly due to a coyote attack. I think it was the unexpectedness and helplessness that came with the loss that made it so bad. It still hurts to think back on it.

I'm so sorry that you lost your friend.

Re: Electric hiking cart hub motor

Right. The only point in using a smaller integrated wheel would be if you are OK using that smaller wheel. Some of them take rather wide wheels that could be run at lower PSI to better deal with off road irregularities. But the small wheel would be a problem if if had to deal with large obstacles.
