Re: Tempted to lick my 50 volt battery

Pretty much. Part of your tongue would become lifeless and cooked, not indifferent to frostbite. It would rot or fall off, taking you out in the process.

I second the ear to ear idea, less painful as ears have much higher resistance and we don't know what will happen.

Re: EEB upgrade to coaxial swingarm @48v???

I did some research and my battery is good for 100a continuous draw so using the 80a controller should be about 4300w on a full charge. It looks like the drive side has a 32 tooth front and 43 tooth rear. I am assuming there is some reduction built into these motors? If it turns a similar speed as ...

Too bad that site doesn't ship outside Europe. They could probably sell more parts.

Re: Stop-a-flat tubes

Sealant has been invented, no point in putting heavier stuff that something long enough will still poke through. I have impossibly thin tires with some Slime sealant in them and I go not only off road but off trail too. Sealant doing it's job perfectly.

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.

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...

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...
