Re: cute Q100 casette width

A 9-speed (or 8- or 10- speed) freewheel will screw on to the threads of a threaded hub. But they're wider than the hub is designed to accommodate, by about 4mm. So you would have to add spacers to the axle to make extra room, and then the hub becomes wider than your bike's frame, and the rim doesn'...

Re: Forget ebikes. E-unicycles are where it's at!!!!

I just got one that does 40+ MPH. Almost 2kWh battery. Ridiculous range, silent. Only bad thing is no suspension. But it kicks ass. Consider that this might be a pass/fail test, where the method of passing is to say, "no, thank you". And where the method of failing is to get fed through a tube.

Re: recommendation for DD hub motor for 20" wheel

Increases in shipping costs, pressure on the Chinese supply chain, and the zealous devaluation of US currency, mean the same things that cost $150 a few months ago are going to cost more now. Get used to it.

If you're really tall, or your bike's wheels are really small, then you can hang bags from the handlebars. But it's still better to use a basket.

Re: cute Q100 casette width

Alright, so the recommendation is to go for the q100h. Noted. Then I shall see if I can find a 8or 9-speed shifter so I can use that motor with a screw type casette :) "Screw type cassette" isn't a cassette, it's a freewheel. Freewheel hubs are spaced for 7-speed, which is narrower than 8/9/10. So ...

Re: Motor noise issue

Is the chain too tight? That might or might not be a source of weird noise, but it's destructive to the freewheel even if it isn't noisy.

Hi Does anyone know if the q100 will take a 10 speed casette? 8, 9, and 10-speed cassettes are all the same width and fit on the same freehub bodies. As motomech said, there's no good reason to prefer 10-speed over 9 or 8. It doesn't take very many 10-speed replacement chains and cassettes to excee...

Re: Thoughts? Ebike ticketed/conviction upheld (Canada)

That is not helpful, ELI5 Idaho law says that bikes can treat red lights as stop signs (stop, then proceed when clear) and stop signs as yield signs (no requirement to stop if there is no cross traffic). A few other localities in the country have adopted some version of this practice. https://www.o...

Heh. If I had a FLBS the rim would be there. What we have is bike shops a 30 minute drive away, who are backed up for weeks and charge an arm and a leg for any real work.
I doubt they'd charge you much to tell you what size wheel you have. There wouldn't be a charge for that at my shop.

Re: 1500w.. Minimum ah?

Check the controller. If it's really a 1500W wheel, then I guess we have to assume it puts out at least 30A. In that case, you can get there with a battery that can handle a sustained 32A output or 30A at 52V, though a higher limit would be better. That’s input power. Most motors are rated by nomin...

That's not true. He or she weighs 100 lbs. You can get a 36V pack on eBay for like $100. One of my buddies recently bought a 36V 16Ah pack for $140 shipped, from a US seller. That's a much bigger pack than a 100 pound person with a 250W bike needs.

Don't sand them until right before you weld them. At that point, whatever rust preventives you use won't impair the welds.

Trikes don't do well on cambered surfaces, at all. That includes the curb lane on a lot of streets. If you want to turn, at speed, towards the uphill side of the camber, the trike wants you on your head. Granny trikes become terrifying at about 15 mph, and most tadpole trikes at about 20 mph (if the...

It's all about the gearing. Even that MY1020 would have been peppy with enough reduction. You have to be realistic about speed, though. If you reckon what your maximum motor output power is, and how fast you can physically go with that much power, that implies a certain gear ratio for highest top sp...

Re: Schwinn Electric Bike Controller

That T06P controller is underpowered for your bike. You'll want to keep current (amps) the same as before, so you don't lose performance. So if you increase the voltage, you're looking for a 350-400W controller, not 250W. The motor will be fine with even more current than before, but the battery may...
