That's quite a big controller, and dated 2015. Have you got the LCD3 to go with it? If so, there's probably a setting to reduce the current in it. It depends which software version it has because there were several and different ways that the current was adjusted. In the early ones, you could...

It's not the cogs that make the noise. It's electrical commutation. A noisy motor goes quiet when you use a sine wave controller.

You can fit a rack to any bike. I've even made my own, which doesn't take long using aluminium tube from Wickes. One of these batteries would probably fit. The 7Ah one would take you at least 25 miles as you're not very big. You'll probably have to increase the size of your chainring, as the...

The one thing I miss more than anything since I ritired is my ride to and from work. How weird is that?

Rear hub-motors always sound quieter because they're behind you, though with a sine wave controller, they are very quiet anyway.

I wouldn't recommend getting one with any motor type. Spares are very difficult to get hold of, and you need diagnostic equipment to find the causes of faults, which hardly anybody has anymore. Also, the harmony system is a bit wafty as well as being very heavy. You may need help from a dealer...

In principle, if it's a rigid frame, you can fit a rear motor kit with a rack battery. For more detailed advice, we need to see a photo of your bike and you must give details of the type of gears on your bike and how many speeds they have

The speed only reading 6km/h was explained in post #19 and the C500 manual setting 4.2.1. APs should be changed from 6 to 1. I'm surprised that Yosepower didn't know that. You get screaming from the motor and weird speed displays when you don't push the motor connector in all the way to the...

Some batteries have remote switching, which is what the lower voltage pin is probably for. Other ones, but not yours, have comms between the battery and charger. The only way to figure out exactly what your pins do is to is to folloe the wires from the receiver pins. Batteries with comms to the...

and they always make them look weird, so nobody wants to buy them, anyway.

A skilled welder with the right equipment would probably have trouble fixing your frame. With no experience and the wrong equipment, you have zero chance, and it's not possible to weld steel to aluminium.

It says that it has "fewer moving parts", but it doesn say what it is that they're comparing it with. One thing's sure - it's going to be tricky to hack the speed limit.

Your assumptions and conclusions are wrong, also the way you're measuring it is wrong. Tell us how many pins are there on the charger, then we can explain what's going on. How heavy are you?

OK, probably best to go with the 17 amp KT controller then. It's a little bit bigger than the 15A one. I just wanted to make sure that you had ebough room for it. You need the LCD3 to go with it...

Excellent result. That's going to be really useful for anybody else that buys one of these bikes. I used to recommend them very highly, but the speed restriction isn't very popular. At last we have a cheap way round it. This method will probably work on the Carrera bikes and any other with a...

The PAS should be OK. The KT controller has lots of settings for it, so one should work.

I hadn't heard anything about the super high-tech Copenhagen wheel that was supposedly developed by MIT, so I just had a look around and found this. The guy is a bit verbose, so you can skip to the two letters at the bottom to see the nitty gritty of ownership. They've stopped selling now and...

You take a photo on your phone, transfer it to your PC or the cloud, then, at the top of the post is a picture, click on that and drag the photo into it. It couldn't be simpler. Where is your controller mounted at the moment?

Woosh, E-bikesdirect, Wisper, Juicy, Ebay. Only buy from Ebay if you can fix it yourself.

It could still be a good buy if it's not the motor wheel that's damaged. You can buy complete bikes for £25, and swap the wheel if it's the non-motor wheel or buy a used wheel from ebay. Wheels are pretty much standard and fit any bike.
