    high rpm motor jerk/stutter

    The controller is probably going out of sync at high rpm.

    No help here

    Your question wasn’t insignificant, it just didn’t provide any information whatsoever for anybody to answer. Try this: We have an old Chinese e-bike and are replacing the controller with a (type the make and model of the new controller and post a decent photo showing the controller and all of...

    Electric Pallet Jack - can I power this with an E-bike battery

    I think the op should reconsider the idea of using a donkey.

    Help selling my bike

    The op lives in Oklahoma. That is a very lenient state for this kind of vehicle, so I’m sure it will be in high demand as a commuter. A decent pair of grippy soled boots should help to bring the stopping distance down. The luminous green paint on the motor casing is especially appealing. And...

    Need help for Ebike axle please

    The thread on the axle has stripped and it needs torque arms. If you fit a decent torque arm either side and maybe a couple of spacer washers, together with a pair of new nuts, you should be able to tighten up on undamaged threads. You need to look at the other side to see what condition that...

    Motor ebike FSA HM 1.O

    If you can’t change the speed limit using the FSA system app, then they have probably locked it so there’s nothing you can do.

    Mineral oil inside hub motor

    That’s a long thread and difficult to wade through. I oil cooled a Bafang SWX02 motor rated at 500 watts and have run it for well over 1000 miles at over 1500 watts and it’s holding up well. I used around 75ml of ATF. It doesn’t need much oil. I have also fitted a temperature sensor inside...

    PHASE and Hall Sensors

    I found this chart which only goes up to 1500 watts, and it doesn’t state whether the cable is ptfe or not. Realistically you can only go so big otherwise the wires won’t fit into the motor. I reckon that 10swg ptfe coated wire will do the job and good quality XT150 connectors should also...

    PHASE and Hall Sensors

    You can use house alarm cable for hall sensors because they only carry small signal currents. Phase wiring size is dependant upon the motor phase current which is dependant upon the motor, controller and battery specifications. So nobody can answer that question without knowing what motor...

    Stealth Bomber - Error 07 - Help !

    Is this a real Stealth Bomber or a kit bike? One of the things you can do is a hall sensor test. Here is a good explanation of how to do the test without opening the motor: https://ebikes.ca/documents/HallSensorTestingFinal.pdf

    Started My First Electric Conversion Project - Problems with Votol Controller

    You may get a better response if you create a new thread stating that you have a Votol controller. I don’t know very much about them, so I can’t help, but I do understand what you are trying to accomplish with this build, using these components.

    Started My First Electric Conversion Project - Problems with Votol Controller

    Here is a top of the range Razor that has been modified. It still has a small back wheel and a large rear sprocket.

    Started My First Electric Conversion Project - Problems with Votol Controller

    It looks like a pit bike motor to me like this one: https://www.amazon.com/dp/B0D3LSS5QK/?tag=mopedarmy-20 In which case it does indeed have 3 pole pairs. The motor has very low torque and operates at very high rpm, so it relies upon low gearing. That’s why it has a tiny front sprocket and the...

    Trump is against everyone having an electric car

    Yep and these third world self taught mechanics are also getting quite good at building electric vehicles from stuff they find laying about in scrap yards.

    Over tightened M14 axel bolt

    If you are having to tighten the wheel nuts that tight to stop the wheel wobbling then your problem could be worn motor bearings. And if you have stripped the threads on the axle then you may as well buy a new motor mounted in a wheel. Here is a link to Voillamart Uk. But you can probably fInd...

    When I was in India I met a fella who was building a complete car from scratch out of scrap metal using an arc welder and a ball peen hammer.

    Gio Ultron controller help?

    This is your controller. It looks very similar to a Votol. It’s probably locked, so you need to consider replacing the controller with an unlocked one, get a compatible display, do some rewiring to get the ancillaries and new display to work, then configure the new controller so it works...

    Kill Switch-Brake cutoff switch

    If you have a BBSHD then the kill switch can be wired across pins 4 and 8 on the brake switch socket in parallel with one of the brake switches. So either the kill switch stops the motor or either brake switch.

    Kill Switch-Brake cutoff switch

    Here is a thread describing how to wire up the BBS brake cut out and more importantly how not to do it. If you get it wrong you will blow your controller. Note from above, some brake switches are 2 wire and some are 3 wire. The BBS has a 3 pin socket (yellow) so be careful if you have a 2 pin...

    Kill Switch-Brake cutoff switch

    Some controllers only have a high brake input. Some controllers only have a low brake input. Some controllers have both high and low brake inputs, although you will only use one or the other. High brake usually needs a 12 volt signal into the controller to cut the motor. Low brake needs a 0v...
