The putty has an advantage: it doesn’t shrink in hardening.

Regular JB Weld does not shrink either.

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...

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.

So on average..its fairly safe to increase the voltage as long as i turn down the amps??

Re-read his post. What he's telling you isn't that simple.

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. Sometimes it is fun to fix something just to see if you can. Also, you could use it as a spare if you get a new one anyway and it is one tiny bit less bit of j...

This isn't an issue where ignoring it in hopes that it will go away is going to work. wturber may want to just give the guy a pass ... I don't know enough about what he posted to have an opinion on his posts. But if they were anything like the PMs from him that I saw others post, I'd be very judgme...

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.

I am old. Any one here play with Cox .049? Model rockets, Control Line Planes, RC Planes. Still got my gas RC planes in the attic. I had a Golden Bee .049 with integral fuel tank. I built a balsa wood and silk screened Aeronca with U-control. Flew it once and it crashed badly. That was the beginnin...

You need to set traps to catch bike thieves, and after you caught a few in your neighborhood, you should be able to keep a bike safe for a while. Are you suggesting involved traps with "bait" bikes (like "bait" cars) or do you have something less elaborate in mind? Setting thieves traps is another ...

Are you suggesting involved traps with "bait" bikes (like "bait" cars) or do you have something less elaborate in mind? I guess if you leave them in the traps, that would send a clear message to the other thieves? trap.jpg I'm guessing that kind of trap is not legal in most municipalities. Not that...

Not a big fan of the 555 timing options either, sounds slow and lazy for my purposes. you can make them flash faster tahn you can even see is flashing, if you like. look them up and you'll see. it's a cheap and versatile chip and simple to use. just that it's completely diy and will be something yo...

If saving money is the goal, #1 rule is, only buy what you can afford, as in paying cash. If there are other higher priorities, then forget about trying to "justify" it with abstract economic BS, just get what you want and enjoy the ride. I agree 100% with both main points and would add that this i...

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.

Maybe post a picture of your situation and perhaps someone will have a good idea for you. I agree with Amberwolf on the JB Weld. I've done testing with JB Weld and some other toughened epoxies (West System's G/Flex and a Brampton epoxy for golf shafts) in a fashion similar to the Dr Bass video. The ...

I like rear hubs , but not for Hills / Mountains . From a legal standpoint it would be safer to build a high powered hub motor based bike if you want to go over 20 mph and still not have to register the bike. The OP was talking about building a 5kw bike. Others here seem to think that hub motors wi...

From a legal standpoint it would be safer to build a high powered hub motor based bike if you want to go over 20 mph and still not have to register the bike. Montana has some interesting laws in that currently a moped with 2 hp that doesn't go faster than 30 mph does not have to be registered while ...

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.

You seemed to not have noticed that the "G" is capitalized. No. I ignored it because it isn't relevant. That is a compound word for which the rules of capitalizing have been broken to make the two component words more obvious. But regardless, you seem to want to ignore the other point about religio...

The holidays are over and nothing has been done that wasn't already tried before without success. Religion is strictly prohibited on the forum, that means including a religious (or sacrilegious depending upon your viewpoint) reference in every post is verboten. That means the forum name ElectricGod...

If you opt for something like I suggested above, I'd look for a sinewave controller. Standard square wave controllers make a kind of "grinding" noise at low frequencies (RPMs) that might be annoying on a hike. It is no big deal on my ebike since I only operate at the low RPMs for a short time as I s...

Just to follow on regarding simply running a motor at lower power, I ran the following simulations: https://www.ebikes.ca/tools/simulator.html?motor=MMAC12T&hp=0&mass=45&grade=10&throt=60&axis=mph&motor_b=M2706_SA&mass_b=45&hp_b=0&throt_b=45&grade_b=10&bopen=true&batt=B4823_AC&batt_b=B4823_AC The fi...

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.

I was hoping there was a motor that was specific made for something like a cart or wheelbarrow that would work with the bigger wheel. Looks like I will have to go with a chain drive set up. Thanks again for the input and information. There are all in one 16" wheels that might work for a "wheelbarro...

I've never had notable relief from CBD, ibuprofen, etc. Almost every anti inflammatory will prevent natural cartilage repair and growth ( look up PGE2 and the COX2 pathway ), so ideally you don't want that.. it's like repeatedly throwing new tires on a car that's got a severe alignment problem. CBD...
