Re: eGO Scooter Conversion

Comparing the two pictures, I am asking myself, why most "modernisations" of old vehicles (not only this one, also motorbikes etc) go towards less usability in "every day situations": No luggage rack, no mudguards, no lights... Many times, it's because those are the parts that g...

Re: Desire Expert regarding rims/tire sizes - explanation

Thanks Chalo, So, are you saying that a typical 26" Fat 4" wide bicycle tire will have a 524 bead seat (or something close to that?). No. Only 559mm. The inside diameter may be 524mm, and the outside diameter may be 573. But because the bead seat is a feature down inside the rim channel, ...

Re: Cleaning inside of motors

I'd use rubbing alcohol on a soft cloth. If it doesn't need cleaning, it's fine to leave it alone. I would not remove the stator unless there were a good reason to do so. It's easy to hurt the hub motor or yourself while getting the stator out and back in.

Re: Convert from DISC brake to RIM brake

Why do you need spacers to get the disc rotor aligned? Are they on the axle, the caliper, or the rotor? Rim brakes are also subject to alignment issues when the wheel is installed. If you are having difficulty getting the wheel to set up consistently every time you install it, then that's the proble...

Re: Very Impressed by fast motor winding with gear reduction vs. Slow motor Winding without gear reduction

Brakes are better at braking than non-brakes. You're bending over backwards to do things sub-optimally.

I argue that flatted axle torque retention as used in almost every Chinese made hub motor is unsuitable for regen braking. It barely works for non-reversing torque transfer.

Re: Looking for a better controller

The chances of the pin outs for the motor phase and hall sensor matching up between controllers of different brands are probably small. With the usual jumble of separate plugs, that's absolutely true. But so far, every 9 pin motor plug I've tried has worked without modification. At least Bafang, KT...

That's how freewheels have always worked. They do the job just fine when used as directed. If you need to do something very different than that, then you probably shouldn't be limiting yourself to bicycle parts.

Re: Very Impressed by fast motor winding with gear reduction vs. Slow motor Winding without gear reduction

If your route starts on a hill, with the battery fully charged, then that's the only time you'll have an issue, due to overcharging, not overcurrent. He'll have an issue when the axle nuts loosen, or the torque arms wallow out, and the axle spins. At that point it'll be new motor and new frame time.

Re: Very Impressed by fast motor winding with gear reduction vs. Slow motor Winding without gear reduction

So let's say I wanted a peak Regen of 2000 watts (for heavy weight on steep hill) that means I would need a 2000 wh battery if looking for 1C Regen charge rate. You could stick your foot in the spokes for braking, too. But it works better if you use your feet to push pedals, your motor to propel th...

Re: eGO Scooter Conversion

That's cool. I have thought about doing that to an eGo belonging to a friend of mine. Not only does it give you a better and more efficient motor, but it frees up a lot of space inside the chassis for different batteries and/or robust onboard charging.

I'm curious what your battery solution was.
