    Many of the integrated controllers are ade by KT. Which display did you get with yours? If it's a KT one, you can change it for any other KT one.

    Help! C300 Handlebar Display

    Yes, but I always cut them off and solder the wires. I'll use connectors if they match because I'm lazy, but if the connectors don't match or the wires are in the wrong sequence, it's much quicker and easier to get rid of them.

    Help! C300 Handlebar Display

    That's a shame. You'd have to cut off the connectors and extend the wires down to the controller, or you can buy a pair of the crappy brake levers with the controller, or you can buy one or two HWBSs. They fit on the brake cables. You have to cut 2" off the outer to make room for them, or you...

    Replacement controller for Tongxin motor

    It's not the controller that will blow, it's the motor. From memory, they used to use a 12 amp one, which is a bit lower than most. 15 amps is more normal. Some controllers with LCDs have adjustable maximum current via the settings, but I don't know how well they'd work with a sensorless Tonxin...

    Cyclematic powerplus power problem

    I've already told you, if the throttle lights don't light up, it's nothing to do with the controller. The black and yellow wires that go to the throttle and power those lights are connected directly to the main battery wires that go into the controller. Put the battery back, switch it on and...

    Extend battery wire

    15 amps max, so 14g will be fine. You can buy shorter hunks on Ebay that cost less.

    hi folks new member down mayday mayday lcd info needed

    It sounds like it's doing the self-learning procedure. There are two single wires joined to each other. If you have the explanation picture, it will say "self learning" or "intelligent..." something or other. You have to disconnect them when switched off and leave them disconnected.

    Brexit, for once some facts.

    Why hasn't Biden started a law suit against NYP and Giuliani and all the others? Why hasn't he denied that it's true?

    Brexit, for once some facts.

    Do you still think it's a hoax? Why are all these senators writing to Christopher Wray to ask wtf is going on? I'm just going out to get a couple of kilograms of popcorn. https://pbs.twimg.com/media/EkjB13NX0AAhUww?format=jpg&name=large...

    In that case, speed is pretty meaningless. The motor has it's own speed, which is dependent on voltage. It will spin 33% faster when the battery is fully charged compared with when the battery is nearly empty. It makes it's max power at about 75% of it's max speed (wheel in the air). In the...

    In case you don't know, most folded bikes are an awkward shape when folded, and they still take up a lot of space. It's much better to just fold the handlebars and pedals so it goes flat against a wall rather than fully folding it. You can put folding pedals and quick release clamps on the...

    Brexit, for once some facts.

    Just one thing undermines your arguments and facts. The story has been published by The New York Post - one of the longest established newspapers and with one of the largest circulations in the USA. If it weren't true, wouldn't the Bidens be suing them for billions of dollars? Hello! Why have...
