Thanks. I'm on my tablet, which can't copy links like a PC.

That sort of servicing is great for people that haven't a clue about bicycles, who can't see or feel when their brakes have stopped working or when their tyres have gone flat. Taking in your bike to a dealer for service is a real pain for most people, and it's my biggest single consideration...

That discount doesn't sound much for an ex-demo bike. Normally, you can get last year's models brand new for a bigger discount than that. Check out www.e-bikesdirect.co.uk They have it brand new for £4099.

When you build your own battery, you have to factor in the cost of the wire, the circular end-cap insulators, insulator sheet, the spot-welder, case, charge and discharge connectors, case, large soldering iron and test equipment, as well as the cells and the BMS. It never works out cheaper to...

It's simple. Switch off the power and pedal as hard as you can, then boast about what a fantastic electric bike you have.

If only they had come here for advice. www.bbc.co.uk/news/uk-scotland-scotland-business-48797265&ved=2ahUKEwjK_rqGqpPjAhVQUBUIHdlmDQgQFjABegQIBBAB&usg=AOvVaw21-oEHgHxKhLsgGIiauTyS I can't make the link work. Google this "Drive for electric bikes to replace delivery vans"

A motor like that running at 45 amps would have to go in a steel frame with substantially reinforced drop-outs. You need a battery able to supply at least 45 amps continuously. You need a substantial rear tyre - something like 2.3" minimum. Finally, you need the best hydraulic brakes, not...

Yup. I bet he didn't set the low gear end-stop, so when you selected bottom gear, it pulled the derailleur into the spokes, which snapped it off.

Brilliant, It must be this one. can't you cut one off your vacuum cleaner?

The LCD has the function in the software to send a signal to the controller to switch the lights on, but your controller doesn't have that possibility to respond. Also, it switches the backlight on so that you can see the LCD in the dark. If the backlight doesn't toggle on/off with a long hold...

It's nice to see that someone gets it.

It's a standard electrical connector. Any electronics shop should be able to sort it out. You don't say exactly which one you have, and there are many different ones. If you show us a photo, we can tell you exactly where to get it fixed - like if it's a jack, take it to a PC repair shop and if...

1.2v to 3.8v is normal. You should do the ptontiometer test if you want to know specifically how your responds.

That's true, but the problem is not just the strength, it's metal fatigue. The constant on/off of the torque will eventually crack the drop-outs. I've seen four sets of broken drop-outs with my own eyes. One of them was on one of my bikes that had a properly installed BPM with two sets of...

Good find. I enjoyed that.

Manufactured bikes have drop-outs that fit the motor axles, and they choose suitable forks. DIY conversions have random forks, most of which are not suitable. While I think of it, I forgot to mention that you also have the problem where there's insufficient clearance between the forks for the...

That's good. This is how throttles work. The hall sensor has a 5v supply, and in its natural state, it will output 2.5v, which is equivalent to half-throttle. The moving part of the throttle has two magnets with opposite orientations (N-S), usually joined by a iron strip. When the throttle is...

Seems a bit tunnel vision to me. 1. Any difference in weight is basically 35mm of 12mm steel bar with its sides shaved off. cassette motors are normally lighter than their equivalent fronts because they're narrower. 2. Both motors involve two 12mm nuts to remove, though any DIY conversion...

It could be OK. The easy way to tell is to make a switched bridge between the signal wire and the 5v one. Wind it up to full speed with the throttle, then make then bridge. If it speeds up significantly, a different throttle would help. Did you check the 5V? it's always possible that something...

It all makes sense if you're an optimist. i guess I'm a pessimist.
