Re: GNG mid drive *sometimes* does not respond to throttle?

It was one of the kelly reps that suggested the 12v input thing for the halls. Maybe there is also a setting about what voltage hall signal input to expect.

Re: GNG mid drive *sometimes* does not respond to throttle?

No need, that was perfectly clear. I've changed it over to the 12v wire and it happens less often and when it does it seems to recover more easily, will keep investigating... Thanks very much for your help! Really, would be lost without it. Maybe it will happen a tiny bit less often when the bike i...

Re: GNG mid drive *sometimes* does not respond to throttle?

If I manually move it backwards it does indeed start working again. This isn't the controller from the gng website, I wanted something smaller to fit the frame better (and potentially be quieter) and thought this might do the trick, perhaps not such a good idea in hindsight. I've looked over the di...

Re: GNG mid drive *sometimes* does not respond to throttle?

If you spin the motor freewheel backwards by hand (it will also spin the motor), and try to throttle again, does it start working again? If so it is hall related fault, it is known cyclone and kelly controllers don't really like each other (well the cyclone motor/halls are just really bad noise wise...

Re: CYC X1 PRO new build

This is not correct. The controller is not power-limited; lower volts will not get you more battery amps. Current is limited to 90A within the input voltage range. At 90A, 52V = 4680W, 72V = 6480W, subject to thermal cutback. Adding battery is also the single most effective thing you can do to impr...

Yeah you're probably right - Chances are, if you make the perfect looking suspension before you ride it, it won't ride perfect and you will have to make a new one anyway.

Re: Seeking advice for commuter e-bike setup

I had an urban commute, 13mi each way, didn't charge at work, 1.8kwh battery was comfortable, cycled it between 75% and 30% each day. Average speed 20mph. 0 pedaling. At 20mph, pedaling along would only get you about 33-50% extra range.

Re: EM3EV Hard Case Battery Issue

If the battery is rattling inside the case stop whatever you are doing and fix that problem!!! It WILL damage the cell overtime and WILL become a fire hazard!!!!!!!

After you fixed that you can think of a better mount.

Yeah, that's the vague plan. It's expensive because the welder only has 1 PCB with everything direct soldered to it so the only way to fix it is to replace the whole board :roll: .

Re: Custom frame for the Cyclone Coaxial motor

I would change that pedal freewheel, it usually goes bad pretty quickly (locks up). Even DNP from aliexpress is a step up (not a big one). 600$ to repair it sounds like robbery, I would get a quote from another welder repair shop. If that is also expensive, I would sell the welder for parts on ebay ...
