Re: Gonna get a used model S

There's no getting around it: cars are for chumps. They are one of the principal tools by which ordinary people are deprived of their ability to build financial equity or personal freedom. And then they use this tool that was already being used to beat them down, to beat other people down with. It's...

Re: IT'S ALIVE...... BBS02HD!!

I actually broke 3 spokes on my rear wheel but not sure the constant stress on that wheel from acceleration caused them to snap but its ben replaced. Chronic spoke breakages are almost always the result of spokes not being properly stress-relieved at the time the wheel was built. There's pretty muc...

Re: Pedals coring out mounts

Don't know what you need exactly, but really cheap MTBs can come with steel square taper cranks. Terrible chain rings on them though. Might work temporarily, till you figure out a better steel crank. I have gotten cranks like that (plastic clad steel) to see if they're good for anything. (They were...

Re: Yamaha FZR-8000 Genesis

If you compare torque it makes more sense, I'm putting a motor with ~280nm of torque in a bike that originally had a maximum of 262nm in first gear(102nm on the motor and that's at 8500rpm). That's a decent point. The all-up weight is probably more like a literbike than something in its HP class, t...

Re: Yamaha FZR-8000 Genesis

Awesome, you can squeeze a "reliable" 40hp from a motor rated for 10.7hp... but you put it in a 145hp (stock) chassis?

Re: Yamaha FZR-8000 Genesis

8000W is almost 11hp. Why start with a bike that had 145hp? I know it's a cool bike, but that's like putting a golf cart motor in a Formula One car.

Re: Car replacement E-bike that fits me

Given that those are toe clips, not heel straps, do be conscious of the possibility of crippling yourself by running over your own legs. It's probably more likely than the battery fires that have us all spooked.

If there's no rear brake, you can use a smaller diameter wheel with a fatter tire.

First, lose some weight. You are way too fat. It's easy, eat fewer calories than you expend while meeting bare nutritional requirements.

Re: old motors inefficient?

There is little to cause inefficiency in a hub motor other than perhaps holes in the winding insulation. My first suspect would be the controller. Or a change in your tendency to run at max speed and full throttle.

Why not power them with an inductor? One one the fork around the axle, Non rotating. The other around the axle , almost touching the first coil.
Now that's clever.

The mount is one of those things that a lathe would be best at. No offense to CNC frosting bags.

Also, what is the best way to connect the lights on a rotating wheel to the main battery? It's called a slip ring.

Re: Pedals coring out mounts

Pedal threads all tend to be pretty short, because the thread length in cranks tends to be pretty short. Threaded interfaces between like materials (e.g. steel pedal spindle in a steel crank) carry pretty much the entire thread tension on the first three turns of full thread. That changes when one o...

How long is the strip you have? If it's long, you may be able to get a resistance reading out of it with a good multimeter. Measure its length, then measure its resistance.
