Always charge to 100% to avoid any problems. The charging system can't complete all its functions if you partially charge. 1000w controllers and motors tend to wear out batteries like yours pretty quickly regardless of how you treat them.

It's not as simple as just a difference in the control panel. The LCDs are often paired with a controller that gives a much better control system. Many of the cheaper ones with LED panels are quite agressive in the way the power comes in. Basically, they give full power as soon as you pedal, so...

To use the bottom bracket you have, you need the pedal sensor with the separate magnet disc and sensors, not the combined V12 thing, otherwise buy a new BB.

First che k thatyour motor conne tor is fully in and that any connectors ar the controller are tight. If they're all definitely OK, then your motor is losing sync with the controller so you have to play with the settings P1 and C2. Whatever is causing it, you'll blow the controller if you try...

If your controller has the self-learning wires, you have to redo the self-learning procedure until the motor runs forward. Disconnect the wires and run the motor for a few seconds. Switch off the bike and disconnect the battery. Attempt to switch on the display without the battery connected...

If you're doing it yourself, you can only add a potentiometer to the throttle to limit the speed. The PAS function is on or off, so nothing to adjust. There is one more thing you can do to your bike to legalise it. You can add an external microprocessor to control it. There are two commercially...

When the BBS01/02 first came out, Bafang told me that the 02 had thicker wire in the windings and the motor was slightly wider. Regarding efficiency, it's true that as any electric motor approaches its max speed, the efficiency drops off, but so does the power, so you're wasting a higher...

Forget Hollywood blockbusters. This is absolutely compulsive viewing. It'll keep you going for hours and hours. You've been warned. This film series is completely free and can be redistributed. It's not been made for profit. The guy has done it only in the interest of the truth. It has...

Good find. I book marked it for the future. The problem for OP is that you can't limit the speed on the PAS.

It's always tricky when you can't see it working. Bikes like that normally have one fault, which could be wiring, controller, battery or motor, so the probable worst case is £200 for a new battery, which means £420 to get the bike runing by the time you bought the pedal too. If it has the...

Your motor is running backwards then. Did you look for those two single wires joined in a loop?

Controllers for brush motors are nearly all with only the throttle connector. Ones with the pedal sensor function do exist, but they're very hard to find. I couldn't find one at all last time I looked. You already have speed control on the throttle, so you can limit the speed by a physical stop...

You need a light weight motor for a folding bike. The only ones I've seen in the UK are the Swytch kit. Unfortunately, Swytch have mixed reviews, but maybe they're getting themselves sorted now. Personally, I'd buy everything from China, then you can get the best motor, controller and control...

Good info. I can add to that to complete the story and understanding. Theny are the controller power limits, but on the higher levels, you won't get those powers all the time. When you get to a certain speed, the motor starts reducing the power due to the back emf. It's interesting to watch the...

It's the difference between speed control, where for each level you get the same power but a different speed limit, and power control, where you get the same speed but a different power for each level.

What are you using to control the speed - throttle, pedal sensor, both or what?

These things are very straight forward and easy to sort out. The only thing we need is the right information on what you started with. After 4 pages of discussion, I'm still totally confused and don't have a clue what you have. Fuzzy photos are OK for you because you can see what you have, but...

It's been a long time since I rode a Smart Bike. I can't remember hearing any loud clicking, but I know that the old Sturmey Archer three sppeeds clicked in the higher gears because of the internal ratchets, so it's probably normal. It was more a ticking noise than clicking.

Personally, I always like to tie up all the loose ends because then you know you're not going to uncover further problems after you started spending money. If you're going to try to fix ebikes, you need a meter. You can buy them from £2.50 on Ebay, so there should be no excuse for not having one.

It's natural that everybody tries to promote their own products and way of thinking. We all do it. But that's why we have a forum and people have the chance to discuss and challenge what's written to firther everyone's knowledge.
