Re: DIY vs. Commercial: How/ Why(not)?

You simply are not going to see the garbage that abounds in the bike lane. And you are going to get flats. When you spoke about bad eyes, I just thought you meant reading glasses. I'm assuming you still see a person, but slower, if this person steps in your path you can do something about it. At 30...

If there aren't penalties strong enough to act as a reliable deterrent then why bother creating the law?
Sure. Ask Singapore. That's the way they see it.

Plenty of jurisdictions DIY is banned altogether.

I bet that becomes more common if the frequency of such casualties continues to increase.
Is the frequency increasing? Where are the numbers on that?

Re: dynamo on a bike

This had been done some 10 years ago by an ES member who had built a velomobile. Still, if pedal input is important, better make it efficient. Every energy conversion does result in a loss.

Re: Legal classification of my custom build - Quadricycle? ATV? Wheelchair? All?

Hey all. I have built a custom vehicle that doesn't really fit into one legal category. I'm looking for help finding the laws regarding this. It is a pure electric full suspension vehicle with a perm 132. It is very fast but we've installed a speed dial so we can dial the power back. I think this w...

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.

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.

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.
