A friend brought his wife's bike to me today to figure out what's wrong with it. It's a Woosh Camino. The story was that the bike was taken to a bike charity shop to fix the loose centre-stand. When they tightened it up, the motor cable was trapped under it and got completely squished. The motor...

It might help to show what you have.

9 times out of ten, you can open those logs with jiggler keys from Amazon. Watch a couple of Youtube videos on how to use them.

You can have whatever arrangement you want. Whichever brake is hydraulic will be better than a cable one. Obviously, if you only replace one brake, the improvement is half as much, but a 50% improvement is better than 0%. You can replace any cable disc brake with a hydraulic one. As I said, it's...

Don't forget that the forks shorten when you're on the bike.

Be careful, the main advantage of hydraulic brakes is the control and modulation, which means that you can apply the amount of braking you want - enough to get the wheel to fully brake without slipping. The maximum braking force comes just before the wheel starts to skid. This is the problem...

You can get stem risers from Aliexpress for about £4. I got the handlebars from Ebay for £20. If you order those bars make sure that you get the 61cm version or longer because I've seen them too short at around 51 cm.

You should ask on the German Pedelecs forum. If thare are any spare parts, they'll be in Germany. https://www.pedelecforum.de/forum/index.php

Did you see how I changed my MTB to sit up and beg riding? I changed the bars to Raleigh North Road and added a stem riser. Normally, you'd probably need to lengthen the brake hoses if you have hydraulic brakes, but I just got away with it. That bike is very comfortable now: Before: After:

That's for when they want to pull the wool over your eyes. It makes you want to trust it more than the propaganda it normally spouts. Do you understand how confidence tricks work? It's similar to the phrase "trusted sources", and we know how that worked out.

Incidentally, I was just riding my folding bike with KT controller down a hill. It doesn't have a speed sensor, so it picks up the speed signal from the halls. Each time I pedalled, the speed indicated exactly 15 mph, and when I stopped pedalling, it went to zero. This is pretty obvious really.

That's right. Your test should confirm if it's correct. Thanks for doing it. I still have the Speedict somewhere, but the software has long gone in an old phone. If I can find anything to download, I'll do some specific test with it. That old chart was to monitor what happened with the 2-speed...

When you go down a steep hill and turn the pedals, the motor will spin at 15 mph because it's the motor speed used for the cut-off, not the bike speed. It'll be doing that all the time you're above 15 mph and after you've slowed down until the clutch re-engages. When the clutch re-engages, it...

Hydroelectric and tidal is too reliable: They won't be able to blame the cut-outs on the weather.

I rode my 50cc Honda Dax around the IOM race circuit on Mad Sunday with my mate on the back. We were only getting around 12mph up the mountain, which was a bit scary because of the speed of the other bikes, and the riders wouldn't be expecting a relatively stationary vehicle in the road round a...

The Aliexpress one is £17 for just the front brake with the SM connector and long long lead, and £22 for one with the red 2-pin julet connector with a short lead. Make sure that you get the right one. Some bikes have the orange 3-pin Julet connector with the short lead. The Ebay ones are about...

Do yourself a favour. Chuck all that rubbish and get yourself a hydraulic one. It takes about 5 minutes to fit (3 screws) and you'll never have to look at it again in the lifetime of your bike, while you get consistent, controllable and reliable braking, better than what you had before. They're...

Italian motorbikes always had a reputation of having very optimistic speedos. I think 10 mph would be a good one. Incidentally, all speedometers on cars and motorbikes are optimistic. If you compare with GPS speed, the speedo typically reads from 3mph to 5mph fast. I guess that's so that the...

The late kicking in is not a bug in the controller. It's caused by the motor freewheeling when you're pedalling faster that what it's spinning. It will be spinning at 15 mph, when you're travelling anything faster than that. As you slow down to below 15 mph, the freewheel cannot re-engage until...

If the light stays green when you plug it into the battery, it's probably not making a connection to the battery internals. Reasons in order of likelihood: 1. Charge fuse in the battery blown 2. Charger cable damage 3. Damage to the charge socket from arcing when you plug the charger in and...
