Yes, they should be OK to manage the battery properly. Don't use recycle cells for an ebike.

Police always want to finish interactions with words of advice. I think they're trained that they must do that as a minimum. Here, AY_Audits shows how to deal with that. I don't know how he gets away with what he does. His card must be marked by every police force in the country for what he...

I'd like to know how the guy managed to cram a 560KWh battery into a frame bag. At 15 w/mile, he'd get a range of 37,300 miles. Joking aside, it shows what we're up against. Some cops can be extremely arogant. Can you imagine trying to argue it out with one who has it completely wrong, like that...

Those sort of projects are good for fun, but not worth it if your plan is to get a working ebike. You can buy 36v batteries ready to go for around £100. Also, if I were to do such a project, I's make two 36v ones in parallel rather than 18v in series.

That's the quickest an easiest way to do it. It works very well. No need to make it more complicated; however, it only works if the brake adapter and wheel spacing are right, which yours must be because it was working before. To make sure all that is right, you put the two screws in through the...

MiRider bikes have what they call a boost button, which causes the motor to give power as long as the pedals are turning, so that you can air pedal with no effort. The only bikes with type approved legal throttles are Wisper and Pedibal. There's also this one, which is more like a 15 mph moped...

The fuse is in the battery, so if the problem persisted after swapping batteries, it's not the fuse, so you can forget about that.

Observation of what happens on the LCD at the time of the cut-out would be the most useful thing you could do, as it shows the change in current and voltage. There are very many possibilities, but your description points to a battery connection issue. Places to look first would be the fuse and...

You could try recording the LCD with a video camera if you have one. You can get 1080P ones from Aliexpress for £3 now, or use your phone if you can find a way to hold it in position.

Some good points in it, but he's working for Park Tools. Most of us don't have them, and as long as you have basic DIY skills of measuring and cutting, you don't need them. The length isn't critical, so if you hack-saw it a bit crooked, you can file it level using spacers as a guide. I've done...

Just another thought about something that could cause your problem. The motor connector near the motor has a line that shows how far it must be pushed together. Pushed in tight is not enough. It must reach the line. Please confirm that it does indeed reach the line.

I was only joking. I knew it was atypo. I was just waiting for details of what your problem was. That VR400 was terrible. He made out that he knew a lot, but all he did was look stuff up on the internet and get it all wrong. Anyway, he's gone now and we're real experts here to sort you out...

It's unlikely that it's a reliable bike, but you're probably correct that it's used folding and electric because if it's an 803, it's a fake. Wisper never made an 803. The fakers are not very clever. They always get something wrong that gives them away.

What I found interesting about this one is it looked like the guy had removed the saddle from another nearby bike and was using the tube like a torniquet to break the lock, but it didn't give, luckily for the owner. https://www.youtube.com/shorts/LJ7d38tVtGY

A micro inverter is like converts the DC from a single solar panel into AC for your house. LEDs run off DC. If you want to have power in your shed from solar panels, the easiest way is with a power station that you can get from Aliexpress. They range from small enough to work a string of LEDs to...

30AH cells, so you only need 10 to make a 36v battery capable of delivering 120A. Looking around Aliecpress, I found 10 for £117, but you can get coupons that would get at least £10 off that. the battery would weigh about 4.5 kg for 1100Wh. At ebike currents of around 20A, they should last for...

Good work, thanks. I looked everywhere for a photo, but I couldn't find one that showed that detail. The next thing to sort out is whether a Hailong type battery will fit. I was going to fit the rack battery if I had got an Intercity, but this one needs a middle battery of some sort.

Blown MOSFET happen when you put the motor under huge load, like riding too slow up a hill or holding the wheel still when you operate the throttle. It's very easy to check if that's the problem as long as you have a multi-meter.

On the surface, it's fake. Hailong make battery cases, not batteries. If they're going to cheat by putting that name on it to give you confidence, they've probably cheated somewhere else. Apart from that, everything else seems to add up, so might be worth a punt.

The Argos Challenge Urban bike is a half-folding bike. The stem and pedals fold, which makes it take up minimum space. It would be good if you have limited space in the garage or you want to leave it in a hall-way or something like that. I have a van, so the folding in half is not necessary, but...
