I just looked on Youtube for reviews of the Carrera ebikes from people that had used them for a length of time. I found two videos. Both mentioned the cut-outs. One had his and hers bikes, so that was actually three. All three owners were still running there bikes and living with the cut-outs...

Whatever bike you buy, you need somebody that will sort it out if anything goes wrong, and if you're going to do that yourself, you need to make sure that you can get hold of spare parts. There's a Halfords in nearly every town, so, with that in mind, their Pendleton Somerby could be a good...

You've probably blown a mosfet in your controller, or your motor phase wires have melted where they come out of the controller. First, check the wires at the controller, then you can measure with a multimeter whether any mosfets have blown by measuring the resistance between the black battery...

A wattmeter is a nice little project as something to add to your ebike for a while. It teaches you a lot about how the control system works, while it also tells you everything about battery voltage, consumption and capacity. You can buy a £10 wattmeter from Ebay, take the shunts out and make a...

That's very interesting. Something isn't right is it. How can there be so many problems reported here and elsewhere, even on fairly recent purchases, and they don't know anything about it? It reminds me of when I was quality manager for Avondale caravans. We were getting loads of people ringing...

I can often crack them without using any tools, though not so much success with the padlock type. It depends on the design.

I did that conversion. It made sense because the owner wanted it to show off. It has very little practical use. Here's my advice/help that you asked for. If you want a bike for proper off-road use, buy one with a Bosch, Yamaha or Shimano motor. If you want a bike for commuting, touring or...

I was going to throw out my old food mixer yesterday. Now I know what to do with it.

That's a big wall of text to say, "What do I do with the brown and white wires?" Brown and white are for lights. Best not to use them because if you overload the transistor, it can damage the LCD. Set P07=1 for speed display.

Chance of connecting is zero. Do not try to connect it to your throttle connector or you'll kill it. It looks like the LCD for a Sabvoton controller. The controller is massive and costs over £200. Maybe ask next time before you commit your money. If the price was uncomfortably low for them...

2.147 microns of rubber would wear off per minute. After about 39 minutes, his legs would start to ache. Finally, after approximately 1 hour and 51 minutes, he'd have to get off and walk.

I've been using LCD3s for more than 5 years, and I discovered something new today that I never noticed before. Above the PAS level indicator is the word "assist", which stays lit nearly all the time. Under some circumstances, it goes off, which I just saw out of the corner of my eye today for...

It doesn't matter what motor you have - they all work the same with the same wires. What's important is the motor controller. Without knowing what bike and controller you have, we can't help.

He did - 12% hill at 4:50!

Please keep your questions and info short and clear. I can't understand any of what you wrote, but the pictures show wrong connections. The brake connectors are black and yellow. You've incorrectly connected one brake to black and red, which is probably a battery voltage supply for lights, so...

Here's the sort of application where a friction drive makes sense. All up weight is 8.8kg. They don't make sense on a heavy MTB with knobbly tyres:

Those meters are a standard part. There are several similar ones that work the same. They fall into two categories, which are those that are digital and communicate with the controller, and analogue ones that are dumb. The 791 can be either, but is most likely analogue. They all have a red wire...

Yes, I saw that too, but it wasn't a Kepler Drive. Kepler was a guy on Endless-sphere, who ran a long project to optimise friction drive as a method of driving an e-bike. there are a lot of clever guys over there, and when they work together, they come up with some fantastic stuff. Kepler sold...

Yup, you nailed it there. People spend too much time worrying about their batteries. Even if a battery does wear out in your lifetime, by that time there will be better ones anyway - lighter, more capacity, more power or whatever you want. They improve about 10% every year, so even if your...
