It's very old. It looks like a brushed motor, but your photo doesn't really show it. The batteries are almost certainly beyond usefulness. you might get enough charge in to test the motor, but I'd be surprised if you get much further than the end of your drive. If it's like the other older...

The connector on the controller must be shorted or the cable between there and the PCB. Follow it all the way to the PCB to find where the problem is. The signal is held at 5v by a pull-up resistor on the PCB. The only way it can signal the brake on is if one of those two signal wires is...

Plenty of cheap folders on Idealworld.tv televison channel. https://www.idealworld.tv/gb/health+-and-+fitness/electric+bikes?icn=h_tn10_c_electric_bikes&ici=c_tn10_c Occasionally on QVC too, and probably others. Halfords have some...

the switch is a simple push-to-break switch. It's held off by the brake lever pushing against it when the lever is in its normal position. When you pull the lever, it moves away and allows the switch to go on. The power is switched off when the switch is on (high signal wire is connected to...

Electric bikes with hub-motors don't work like that. As the speed goes up, the current goes down due to the back emf from the motor opposing the voltage from the battery. I still can't understand from your description what you're saying is happening. Does it do it on level 1 on the LCD? Please...

When you consider how many calories you burn, you have to consider human efficiency in converting food to energy, which is somewhere around 25%. You can do an easy approximate calculation. When riding a bike, an average person puts around 100w through the pedals. You can decide how much you...

No, you've got a 36v battery that charges to 42V and discharges to 30V. The voltage changes during use. The 36v is just a nominal middle value.

They're all much of a muchness and they're all a bit awkward to take on public transport. Even the integrated batteries are standard and can be bought from Aliexpress or you can get them re-celled when they expire.

It's Chinese. They get mixed up when translating. 30V is the minimum voltage when discharged.

What I'm trying to establish is whether your problem causes the current to go up or whether your motor cuts whenever you use high current. Can you explain?

Tooth- ache.

It's not likely to be the battery, but maybe it is because I can't understand what you mean by the current going up. Please explain.

I have a few ideas. they go like this. 1. I must be drunk. 2. I've had a stroke. 3. You must be drunk. It must be something like that because I find what you wrote completely unintelligible. I guess the others found the same, which is why you haven't had any sensible replies. I know the...

I can understand the occasional one, but I reckon it's 4 out of 5 of the recent cries for help that I looked at were for me incomprehensible. Look at the one about the Cyclamatic to see what I mean. Please translate if you can!

I broke a tooth this morning. I think dentures was on my mind.

You're mistaken in what you say in your first sentence. Use the simulator to study the torque curve. You'd be lucky to get 20NM at maximum power. Www.ebikes.ca/simulator

Am I starting to suffer dementure? I used to be able to understand what people wrote when they described their problems. Now, nearly every initial post seems to be in some sort of code. No sentences, no full stops, just unrelated cryptic phrases that are (for me) impossible to separate from each...

You can use a 5k or 10k pot as a throttle. If it doesn't work, think about whether the connector that you connect it to is actually the throttle connector.

Get the Decathlon. It has standard Chinese parts so easy to get spares and fix. If anything goes wrong with the Dapu, you'll most likely be looking for a new bike because nobody sells spares for them.

You need to check whether your motor cable has he white wire in it. If it doesn't, you'll need a separate speed sensor for the LCD to show speed.
