For anybody else reading and for you next time, as soon as you need to spend money on cable disc brakes, you should think about switching to hydraulic ones. They're only about £20 each, so if you're going to spend a five on a cable, the price difference drops to £15. In your case, you had to buy...

How many times have you had to do that on your batteries? What sort of cells are in your batteries that get dendrites? I've never had to do it on any new battery I've ever bought.

When Trump weeds out all the government corruption, do you think that the climate change data will get adjusted, or will it get adjusted to show no climate change for some other reason? Here's his plan from a year ago. No wonder they tried to kill him three times. It looks pretty good to me...

Everything is easy when you know the answers. Everything is complicated when you don't understand it.

The mode of failure goes something like this: Thr crank seal wears and let's in a bit of water. The water gets into the bearing and damages it. The excessive play in the bearing damages the seal further and let's more water into the motor. From there the water can get into the electronics or the...

It's not bearing noise. It sounds like a commutation issue to me. Have you been riding in the rain or into water just before it started?

Here's something you could try: Disconnect the battery and switch on the display. It'll probably flash on then fade off while it drains the capacitor in the controller. Try to switch it on again just to make sure that all charge is gone, then reconnect the battery to see if the display will...

This is how you know it's all a load of shite. Remember all those headlines a few years ago when every country and region was warming up twice as much as the rest of the world? They can't help themselves can they...

What I'm saying is that if you have separate controller and battery and either one has a problem, you can replace just that item, but if they're combined and either fails, you have to replace both. This is the problem with Bosch type and other ebike motors with controllers in them. When water...

Those bolt-croppers should easily go through brake cables - both inner and outer. With the force they exert, they don't need to be sharp. If they're not cutting through, it must be because the jaws are damaged. Show a close up photo of the jaws in the shut position so that we can see their...

The display is basically a voltmeter. It should show all lights when the battery is fully charged. If you have only one light left and flashing at 40.5v, then you probably have the display set to 48v instead of 36v. What's written on the back of it?

Here's some data from Nkon, a trusted supplier. They list it as 7.65A max. My experience says that cells work fairly well up to 50% of their maximum discharge rate, so a 4P pack should be OK at 15 amps. In other words, if your cells are full quality ones, your pack should be OK for the...

The landscape can change a lot, but when there's no sun, you get no power. A major problem is that the demand is higher when production is lowest. Batteries are not enough. Even if I doubled the size of my panels and battery capacity, I would never be able to produce enough power in the winter...

I fitted one to a Dahon Jetstream 8, which has quite a stiff rear subframe. As I said, you have to dish the wheel quite a lot, which is why I'd recommend the freewheel version and 7-speed gears. 7-speed gears are very cheap if you want to change from anything higher.

Here in Telford, I've been using about 8kwh per day. I the last week, my solar has generated less than 2kwh per day. There has been no wind at all, so when my wind generator goes on line, it wouldn't have produced anything. I have about 15kwh of storage in batteries. That was gone after 2 days...

We have one in Telford that comes with a walkway generator that cost over £100k. Nobody uses the bike shelter apart from smokers, and the screen that shows you how much the walkway generates uses about 200 times the power generated.

There are very many good lights on Ebay, Amazon, Aliexpress, etc for around a tenner. Many have their own separate 4-cell battery pack. You can get your own empty 4-cell holder and put your own cells in it, then you don't have to worry about the quality of the cells...
