    Fiido d4s, Replacing the battery?

    Bad luck. That's how it is, unfortunately. It can't be taken out in the way you want. Have a look at this:

    There are some big 250w motors. If you stick to your guns and say it's 250w, it's quite difficult to prove otherwise unless it's written on the motor.

    I don't think it'll work like that. The throttle takes precedence over the PAS, so you can use it to regulate the speed. Without it, you'll get full power all the time up to whatever max speed is allowed. If it were my bike, I'd set it to normal power (actually 1000w, not 750w) because it's...

    2 is not an option. Both Your throttle and pedal sensor give maximum power, which will strip the gears on a 250w motor. You can't regulate power with a throttle because it's a speed controller. I'm not sure what your controller does when you set it to 250w. I'd guess that it just reduces the...

    How does the pedal sensor work then? Does it just give full power? Not having a pedal sensor is completely illegal regardless of motor.

    That controller looks a bit too powerful for a 250w motor, so you'd need to get a new one, which will probably be a big improvement to your bike's usability. Around £40 for a nice one and £70 for a really nice one. Do you have an LCD? If so, show a photo.

    You could replace it with a 36v 250w one, which wouldn't cost much. Everything else should be compatible. Do you know what controller you have? Show some pictures of your bike.

    You can use a 250w motor and run it at 750w, but you can't take a 750w motor and run it at 250w. What does it do when it's set to 250w? If it were set to 250w maximum output, it would be absolutely useless. The average 250w system is 15A and 36v, which is a maximum of 630w when the battery is...

    Brexit, for once some facts.

    I just stumbled across this. What do you think? It might explain Sidney Powell's involvement after Trump said that she's nothing to do with him...

    Clunking noise

    You do not need any new parts. It's a very quick and simple adjustment. A reasonable cost for sorting it would be a fiver, but they try and sting you with minimum charges. At the shop, it would have been quicker to fix it than find their booking in book or computer and book you in. Some people...

    Going faster

    The speed isn't limited in the motor. It's the motor controller that regulates the speed.

    Heinzmann controller/battery problem

    Neil's right. To make it a bit clearer, you could chuck the Heinzmann controller and use a Chinese one, then you can use any battery. you'd have to cut and rewire the motor cable for that. I found this too. £420 -£500 for a new battery: http://www.ev-solutions.co.uk/documents/Retail%20DD%202018.pdf

    Heinzmann controller/battery problem

    It has CANbus comms to the battery, so you can only use a Heinzmann one. You need to talk to a Heinzmann dealer about a suitable replacement. Basically, the controller asks the battery if everything is OK before it will allow any power. It assumes that everything isn't OK if it doesn't get an...

    Brexit, for once some facts.

    Your TDS must be pretty bad if you think of Giuliani or Sidney every time someone mentions the UK economy. Can you explain the links you went through in your mind to get to them from the Governor of the Bank of England? Was it because I mentioned "genius"? Is that the link that reminded you of...

    I don't understand. You took your bike to the bike shop and they found the problem, but didn't fix it? It's a one minute job to fix.

    Help! Fork problems

    There are two ways to deal with Lawyers lips. You either reprofile the drop-outs so that the axle becomes central again so that the nut fits within the lips, or you use eccentric washers to space the nut above the dimple. As I said before, you can file normal 12mm washers into eccentric ones...

    Jeez, that guy's a genius. He's figured out that Covid will be gone by next year, but we'll still have an economy the following one. Wow, no wonder he got the job!
