You've told us everything except which display it is.

Internal speed sensor then, not external. External is wheel-magnet type or GPS.

You're going to be a very popular guy, but not with everyone.

I think there must be something I'm missing. It's £390 for a 48v battery without any cells in it. Is that right? A set of 13S3P cells (Sanyo 18650GA) is around £108. The total cost of a 48v 10 Ah battery would be around £500 without shipping costs, which works out at about £1 per wh without...

The one in the Yose kits doesn't. It only has 4 connectors: motor, battery, 1 to 5 and PAS. 1 to 5 has LCD, throttle, light, L brake and R brake.

That's how KT controllers work, but like many others, they will get the speed from a hall sensor if you don't have a motor with internal speed sensor or an external speed sensor. That's made me think! What does a Lishui controller do regarding the 15 mph cut-off if it loses the speed signal...

I guy was round my house yesterday with that Woosh Camino I mentioned. His own bike has an AKM 128c that I built into a wheel for him. I warned him about labelling, but he said that it was already labelled (engraved ?) 250w. When he bought it, the seller offered him that. He's not sure where it...

Are you talking about your Lishui controller? When using the halls as the speed sensor on any bike, it's obvious that the motor will maintain 15 mph as long as you pedal when the bike speed is above that. When you stop pedalling, there is some friction that tries to keep the motor turning, which...

I have some of those brakes on a bike in my house right now. They were fitted a few months ago, and they were very good; however, when I checked the bike today, one of them is not working so well. I haven't done a full check yet, but one of the pistons is looking shorter than the other one...

Type "Ebike clutch 36T" into Google, then look at all the options. You can change just the gears if you want. You can get plastic or metal ones.

The motor has a connector at its end of the cable. The rest runs all the way to the controller. that's fairly normal for bikes with controllers in the battery mount, and so is potting because the water can run down the battery, through the connector and into the controller. I had a go at him...

Those ones don't have switches in. We don't know how your bike goes without brake switches. You need switches if your motor runs on for a bit after you stop pedalling. These ones (the last option on the right) have switches in them and the same connectors as your present ones. The brake levers...

This situation is quite complicated. Giant generally use Yamaha stuff, which is hackable, but on many bikes, they have their own versions which have their own software and communications protocols. If you have such a system, the Yamaha hacks that allow you to run any battery don't work. First...

A friend brought his wife's bike to me today to figure out what's wrong with it. It's a Woosh Camino. The story was that the bike was taken to a bike charity shop to fix the loose centre-stand. When they tightened it up, the motor cable was trapped under it and got completely squished. The motor...

It might help to show what you have.

9 times out of ten, you can open those logs with jiggler keys from Amazon. Watch a couple of Youtube videos on how to use them.

You can have whatever arrangement you want. Whichever brake is hydraulic will be better than a cable one. Obviously, if you only replace one brake, the improvement is half as much, but a 50% improvement is better than 0%. You can replace any cable disc brake with a hydraulic one. As I said, it's...

Don't forget that the forks shorten when you're on the bike.

Be careful, the main advantage of hydraulic brakes is the control and modulation, which means that you can apply the amount of braking you want - enough to get the wheel to fully brake without slipping. The maximum braking force comes just before the wheel starts to skid. This is the problem...

You can get stem risers from Aliexpress for about £4. I got the handlebars from Ebay for £20. If you order those bars make sure that you get the 61cm version or longer because I've seen them too short at around 51 cm.
