You can run the bike without the control panel if you short the red and blue wires that run to it. In that case, you get level 1 PAS and normal throttle operation. With the control panel open, you should check the voltage arriving at it between the red and black wires. If you get 39v and the...

LCD settings do not constitute an off-road switch. Many bikes have that function and they have official EN15194 certificates after having been tested for compliance. To answer OP, the answer is that if the speed limit is set correctly to the legal limit, then a bike with a 250w motor running...

I've been using ordinary gearbox oil (Hypoid 90) on my bicycle and motorbike chains for more that 40 years. A single bottle doesn't cost much and it lasts forever. I've tried all sorts of expensive modern alternatives. None come anywhere close.

If the control panel doesn't switch on, you only have to follow the voltage from the battery to the controller. None is reaching it, so you have to find out why. Check its connector. There should be battery voltage between the red and black.

Most controllers use speed control for the PAS, so power is always the same on all levels. The levels set a different speed limit on each level.

Here's an interesting one. Two stories for the same incident. The Sun says two people stabbed during an illegal rave, which makes it sound like the normal gang stuff. The Jewish(?) website says terrorism. Their photo shows orthodox Jews and police standing around outside a Jewish bakery during...

His panel lights stay on!

It depends what you want and whether you're happy to do everything yourself or you want a ready-made plug and play kit with guarantees. Obviously price is a factor, and performance characteristics, like power and speed. Another important factor is compliance with regulations. Some people are...

Regarding the pedal assist levels, and in case you don't know how they work, there are 18 different levels. There are three levels of power that you can select before the ride and 6 levels of assistance that you can select during the ride. They work together to influence how much power you get...

The 790 is a standard part that you can get from many of the stockists, but you have to hunt for one with the right connector. Have a look at Aliexpress. Alternatively, you can get one with a different cable or connector, then cut off both connectors and solder the wires together, which is what...

If the lights stay on, it's not the battery, its connections, switch or fuse. If it only does it on high power setting, that eliminates causes to do with the control system unless there's an over-sensitive temperature sensor somewhere. Logically, the cause is somewhere between the controller and...

Not without changing the motor controller. A brushed motor is single phase and a brush less one is three phase. A controller is something like £20 to£70, depending how good you want your bike to be. You might need a motor extension cable too.

Just in case you don't know, the PAS setting on the LCD has no effect on the throttle. It only affects the pedal assist.

His rack has pannier supports and it looks like what's left of a pannier under the wheel. I can imagine something like he sees smoke coming from the pannier with the battery in, so stops and makes an attempt to remove the panniers, but it starts to flare up, making him drop the bike, leaving it...

No, they shake about in there, which can damage the wires. Also, the weight keeps banging against the metal pannier supports and soon wears through the pannier and any insubstantial protection around the battery until you end up with the bear cell-pack bouncing against the metal frame. If you're...

BMSs do have a cut-off, but it's set lower than the controller; however, it never worked at all on quite a few batteries that I've tested, so I would never rely on it.

Show photos of what you have, otherwise all we can do is make wild irrelevant guesses.

Some 36v controllers can run with 48v. There's no point in being gentle. the smoking happens or not when you only connect the battery. After that, the faster you run the motor, the better it is for everything. Some controllers are dual voltage and can switch over automatically. Others are...

It doesn't matter what gear you're in with a hub-motor. Only the speed matters. try not to let it go below 5 mph. The gear you're in affects how much power you can give to assist the motor. You get more power by using a lower gear and spinning the pedals fast.
