There's no way that charger can work on a normal ebike battery with a BMS. When any cell goes below 2.5v, the BMS shuts off the charge port, so no clever charger can get anything through it. If your battery won't charge, the first thing you do is measure the voltages on the charger jack and the...

Another possibility for the bike spontaneously starting up is that you have a fault on your wiring somewhere, in particular, the throttle signal wire. Iit can also happen when the throttle stop is broken. You only get zero throttle when the low magnet is positioned exactly next to the hall...

I had something similar with one of my first electric bikes 10 years ago. I can't remember all the details, but it goes something like this. There is a run-on after you stop pedalling when using the pedal sensor - maybe 2 or 3 seconds. The throttle and brakes over-ride this run-on, but it's like...

Show us a photo of the bike. How heavy are you?

It's dead easy if you go by the measured voltages. You must use the cell-pack ground for your black probe, not the first pin or wire, then put your red probe on each sense wire in turn. 0v goes to B0 if it has one Approx 4v goes to B1 8v to B2 etc. and 56v goes to B14 .

2.4v means that the BMS has shut off. You have to find out why by measuring the voltages on the sense wire connector. Do it when the BMS has shut off, not after charging. When we have the results, we should have a good idea where the problem lies. The voltage reduction from 54.6v to 53.8v could...

Remember though, it's really tricky to diagnose faults and problems if you use the waterproof connectors. I always use the controllers without them.

How much range can you get out of it now before you have to recharge. I bet it beats that guy's range monster whatever it was ?

It might be better to ask your question again in a different way, explaining what you want. AFAICS every question you asked has been answered. Some of us are very knowledgable about electric bikes, but we're not FMRs.

Try pedalling backwards to see if the pedal sensor works in reverse. If it does, you need to flip the magnet disc. The arrow on it should point in the wrong direction when you put it on the left side of the bike.

When you have the wheel off the bike, you turn the wheel backwards and it intermittently locks, in most cases it's because you didn't insulate the bullets on the end of the cable. Try it again, but making sure that they can't touch each other or anything else before judging what's wrong. If...

That doesn't hold for a geared motor when you rotate it forward because there's a one way clutch, but can explain why the motor locks when turned backwards.

Things only get hot when you use high power and low pedal speed. As long as you keep your cadence up, you'll be OK, so make sure that your bottom gear is low enough to keep the pedals spinning when you climb steep hills, and don't be lazy with your gear-shifting. Use all the gears as you...

Don't you know how to use Google?

You must do that speed test. It will show you what's limiting the speed. Until you know what it is, you can't improve anything.

You're learning all the time, though. it's not at all tricky once you understand it all. The battery is good for at least 20 amps. Your present controller is 15 amps, so you can get 30% more torque, but that won't improve the speed unless the results of your speed test show otherwise. It's now...

You'd need a battery that can give at least 25 amps and a 22 amp controller to see a significant difference.

No need to take the wheel off. The cause is not in the motor. It's an electrical problem caused when the timing of the pulses from the controller don't match the motor, which gives the effect like it's being repeatedly hit with a hammer. Check that the motor connector is pushed in all the way...

It's amazing how many new members of this forum join, then post only positive things straight into the 50 Cycles threads, then disappear for ever after.

You need to do the voltage test first with the full and empty battery because you might still be limited by the controller. Which cell-pack did you buy so that we can assess how hard you can push it?
