I've used torque washers without torque arms. I've been riding on mountain bike trails and have had no problems. I think torque arms are probably OK with a 250W motor.

Gave up. Made my own mounting.

I've been given a bottle battery by someone who no longer has the bike. I haven't got the mounting plate and although there are plenty of bottle battery mounts on ebay for example, they are different to this one. The battery has to be swung in from the side, so the top is a bit lopsided. It is...

Sounds convincing, (and comprehensive) thanks!

I've been given an 18650 36V bottle battery by someone who no longer has the bike. I've taken the casing off to check it and was surprised to see that there appear to be two empty spaces for cells, so was concerned someone might have removed the cells leading to an unbalanced battery.* There...

I've got a mountain bike with aluminium front forks and a 250W motor. The motor shaft has a 4mm long, 12mm diameter step with 10mm flats for Bafang-style torque washers. However I have read elsewhere that on aluminium forks the washer can force apart the dropouts so I should use a torque arm...

I didn't mention the controller because it wasn't relevant to my question which was: "Some of this is probably for a pedelec sensor, there might be something spare for the alternative of a throttle. I don't think pedelec sensor control is very safe so would prefer a throttle if I can adapt this...

You've made some good points about this, but since I have the display it isn't a problem. I've done that, but unfortunately it's potted (it's encased in a lump of epoxy resin or similar). It might just need a simple 5V pulse which could be supplied reasonably easily by However it is looking...

Unfortunately there are hundreds with different wiring. I'm hoping there are some common colours which someone will recognise. If all else fails I will try it without the unknown wires - and if that doesn't work open it and hope someone can work it out from the components on the PCBoard.

I have a controller from a crashed bicycle. The battery, motor and display cables are obvious, as are the two small connectors for lights. There is one remaining cable which was ripped out of the bottom bracket with red/black/grey/brown wires ending in a small white plug plus green and yellow...

I have a controller marked LSW669-16 X100-7011-816 and CE:G3M20211-1592-16 on which the battery, motor and display cables are obvious and there is a 6 wire cable to the Wuxing S29X-DX throttle and display which has three battery level LEDs and a big red button. There are also: a medium sized...

I have a Momentum Electric Model-T Hall effect sensor brushless wheel and controller from a written-off electrice bicycle. The controller has 8Fun stamped on the back. I can see which are the cables for the motor and display and there are two paralleled plugs with red and black wires which I...

Well that at least is good news then! As an owner of a Ducati motorbike, I wouldn't have anything to do with it if it was. The motorbike electrics are pathetic. Great fun to ride though!

Controller tube now dismantled.

That was the first thing I did - their website says they should reply within a day. Don't believe everything you read on a website!
