Re: Cyclone motor cutting out, just low battery, or something else?

It is normal and the low voltage cutoff setting can be adjusted with the bluetooth app. The way it works is setting it to 55v will have it cutoff power when the battery reaches 55.9v. If you set it too low your battery bms might do the low voltage cutoff, but they typcially need a charge to reset o...

Re: GNG X1-pro 3000w

Power = torque * rpm You want low torque for drivetrain longevity, but high rpm to correct for it and deliver plenty of power. So 11/53 or even 12/53 with a 32t on the bike chain side instead of the default (bcd 104) 42t front would be ideal. You would still get the desired wheel torque by choosing ...

Can you share a bit about your 150a setup? I have a 4kw motor too, curious how it handles it.
i'm curious too.. I thought the 4k motor was rated for 45a
Those numbers are made up... The motor core is 30% wider.

Its easy. Only 4 bolts on output shaft side. Then take gearbox out and take out lock rings on gears.

Re: GNG X1-pro 3000w

I would indeed like to have 2 (or 3) gears but I was not aware if the chain itself was up to it. I thought maybe it was to stiff to have it not run in a straight line but this won't be the case? The two gears would be as close as possible without any interference, so the chain would only need to fl...

Re: Sur-Ron - New Mid drive Bike

How much price difference there is between BAC-4000 and BAC-8000? Also, would BAC-4000 be enough for 8 KW power and to reach 100 km/h? Also, I'm not sure about the fit, since the length of the BAC-8000 seems to suggest that it can't fit very well. You can go 100kph with 5-6kw. Torque wouldn't be gr...

Why are you so worried about what can you outrun and what not? Is it a track race bike or a drag strip exclusive bike?

You would have to switch in and out when riding and slowing down, which sounds like a hassle anyway.

Re: Sur-Ron - New Mid drive Bike

Most of the expensive forks are air sprung, which supposedly are not as good as coil but are lighter and probably more expensive. We really don't have many options right now at all for quality coil forks in 26". Most coils are only offered in 27.5" now. Have you seen the guy who put fox 40s on? It ...

Re: Sur-Ron - New Mid drive Bike

If you use it as supermoto, and everything else is equal, go coil, it requires less maintenance and more supple, better against road buzz.

Re: Saved by thumb throttle

Don't forget the new crank arm. There's nothing you can do for the one that fell off. For what it's worth, you can feel the crank wiggling for a while before it goes off on its own. But if it wiggled around much, you'll still need to replace it. Purple Loctite is the low strength kind. When mine ca...

Re: Proper Middrive Shifting technique?

Depending on the rpm of your drivetrain, the motor and chain might have enough inertia to complete a shift while off the throttle.

When shifting under power, just hold the throttle to a lower rpm than whatever speed you are going, that way the whole system is freewheeling and not under stress.
