You have to set the number of magnets to 1 in the settings: P07=1

There are three types of controller: (1) ones that only work with hall sensors, (2) those that can work with and without, and (3) those that work without hall sensors. Your motor doesn't have hall sensors, so you can't use (1), which is the majority of controllers. Your controller has the...

First, test it to see if it works backwards. if so, flip the magnet disc. Next, check that the disc goes around with the pedals. Put a finger on it while you turn the pedals to check that it's gripping the spindle. Next, check that the gap is an even 1mm. If it's more than that, wiggle the disc...

Warning about that advice. By all means read that stuff and improve your understanding about lithium battery cells. All that research is about how individual cells behave. You have a battery of cells with a management pcb attached to them and controlling them. You can do harm to your battery if...

Yes How many amps is your present controller - on the label?

You're not helping. Rather than rant about it, you need to denounce your white privelige to get that racism out of your body otherwise you might become a super-spreader. Yes, I have tried speaking to the doctor. I just got a call yesterday cancelling the appointment that I've waited 4 years for.

If you see Dave again, say hello to him from me - nice bloke, he built all my bikes for me for nothing, just the cost of the parts.

Did it say anywhere in the listing that it could work sensorless? If it does, did you do the self-learning procedure?

How often do you use those tools?

On my road bike, I use one of these. It's just big enough to fit a pump, tube, puncture repair kit and multi-tool. It conveniently is held in the bottle cage. I never carry any tools or spares on my ebike. I used to, but don't have any reason to. Fit Schwalbe marathon Plus tyres to your bike...

I have a couple of ebike batteries that can charge in 5 minutes. They're designed to go in some sort of high power charging station, though I've never seen one. they also have a separate port for charging with a 10 amp charger that can charge them in 30 minutes. They're 24v lithium titanate...

There's a small chance that the cause of your problem is in the controller. Only buy a replacement LCD if you have checked that everything else still works, like I explained in post #7, otherwise replace both the controller and LCD.

To fit the gear sensor, get a complete new gear cable wit inner an outer, then you can run the cable where you want and install the gear sensor wherever you want. You often have to do that anyway to get the cables away from the BB.

The sticker means it's a fixed 36v one, so I'm out of ideas now. maybe time to upgrade the whole lot with a KT controller and LCD3, which will be better than what you have. Costs about £70 from China.

Yes, you can do that, but not with any 48v battery. You need one that can deliver the current that both controllers take, which is going to be a minimum of 30 amps, depending on which controller you get for the front motor. I recommend not to go over 15 amps on the front motor because the...

You must only pull the lever one way. use the button to send it back one gear at a time. You'll break it if you try to push the lever both ways.

It's virtually impossible to determine whether a motor is legal by measuring its power. In the case i was involved in recently, the bike had a manufacturers plate on it that said that the bike was rated at 250w. He also got a letter from the manufacturer that said it was rated at 250w. With...

That's a good point. You often see the same corporate press release stuff in all the reviews. Even the good review sites only ever review the bike as it stands in front of them. None talk about cost of running , other to say that it costs 5p to charge, and none talk about servicing and...

Is good to see you back. Where have you been? Is your Cyclotricity Carrera still going?

Look at it this way. I've ben on this forum for ten years answering about 10 questions a week that go like this: " my bebike has stopped working. What do I do". For all the common chinese bikes, you can test them, figure out what's wrong, get spare parts and repair them. This worked great ten...
