Looks good to me too.

Sorry to have worried you.

I forgot that. If they're steel, it would explain why the drop-outs didn't pop. Test with a magnet to be sure. No need for a torque arm if they're steel. Steel forks are not so critical as the drop-outs won't pop like aluminium ones do. File them a bit deeper and check whether the flange of...

The recording device is basically a wattmeter with GPS or speed sensor and data logger. It fits between the battery and controller to record current, voltage watt-hours, speed, etc. The problem with phase current is that it's very nebulous as far as the rider is concerned, so there's no need to...

If you look at the chart I provided above in post #50, which is from actual measured data, it shows that a KT controller provides constant current from the battery on any pedal assist level, regardless of speed. Look at that record and see if shows what you just said. I can't see it.

You should file the drop-outs deeper until the axle is central to the dimples, then fit a 12x20 mm washer and check that it sits completely within the dimple. That will allow you to fit the nut correctly and a torque arm on one side. Be very careful that nothing overlaps the dimple even a small...

When the indicators show half-charge, the battery is nearly empty, so that's your problem. You shouldn't take any notice of what people on the internet say, when you don't know who they are nor what they know. I agree with the others. Without a charger and keys, it's almost certainly nicked...

Nobody can answer those questions without testing anything. You say the battery was half-charhed. How do you know it was 50% and not 10%? The cells are not leaking. I've dealt with hundreds of ebike batteries, and none have leaked stuff out of the case. If cells leak, you get a very pungent...

What do you mean by power? Constant current gives constant torque, which is what we feel as power and is constant power from the battery. Output power is torque times speed, so the constant input power gives increasing output power as the bike speeds up until the back emf starts limiting the...

There is nothing complicated about the rules. It's just that many stupid people can't understand simple English, and they try to make them more complicated than they are. I listed them for you here in a way that you should be able to understand them...

Sorry, I didn't notice the kit that I linked above is the 350w version. You must get a 250w motor to be legal, which, of course, is out of stock. That's why they're pointing at the cassette version. A cassette version will work OK. It's just that the freewheel version would have been slightly...

These are the requirements for an electrically assisted bicycle that doesnt need registration, insurance, licence, etc: 1. Max motor speed 15.5 mph 2. Motor must be rated at 250w or less 3. The bike must be able to be pedalled when switched off. 4. The power must stop when you stop pedalling 5...

The AKM cassette motors are normally 142mm wide, which makes installation a bit harder, and they need the rim to be built off-set a lot more than a freewheel motor, which can give spoke tension issues if not built very well. My rule is 7-speed or less = freewheel motor, and 8-speed or more =...

Aliexpress and Ebay. Get one with a Cree XLM T6 LED and a 4-cell 8.4v battery pack. I'm waiting for someone to try one of these. where's Guerney...

Use jiggler keys. Once the lock is open, you can dismantle it and remove the tumblers so that you can open it with any key, knife or screwdriver, which will save you from having to buy another lock.

The normal KT software gives absolutely constant power on any level, regardless of speed, except when the back emf is enough to reduce the current. I showed that on the chart I provided in a post above somewhere. Can't you chuck out all what's in your software and make it like that? That's the...

I've got two. Did your hear that I got a second one for £100. It was an Argos return - nothing wrong with it except the missing charger and a broken mudguard. I have loads of chargers. If you want it you can have it for £100 plus shipping.

You should get a freewheel motor kit, then you don't need to change anything. https://www.yosepower.co.uk/collections/e-bike-conversion-kit/products/e-bike-conversion-kit-36v350w-26-27-5-28-rear-motor-for-freewheel-with-36v13ah-hl1-battery Freewheel motors are better than cassette ones because...

Yes, same for me. My £245 Argos ebike just doesn't cut the mustard anymore. I'm not going to pay the £8,799, though. I'm waiting for Wisper to offer a discount on it. I asked for £10 off, but got no response. I'm patient. Sooner or later the market for it will be saturated with those bikes, then...

Reminds me of when I had pneumonia. Twice, I went all round the bedroom looking for the loose plug that was making that electrical crackling sound, then, back in bed for the third time, I realised that it was coming from me, so had to get dressed at 01:00 am and a taxi to the hospital. I didn't...
