You'll probably have to do a bit of rewiring of the connectors. The motor connectors are fairly standard. Look at the PSWPower controller to see which connectors match. If they don't match, you can always cut off the connectors and join the wires directly...

Those hills aren't too bad. You will use about 3Ah going up them without having to pedal too hard. Even the Gtech , which has about the smallest battery you can get, will do that with loads to spare.

Test whether the throttle works when you're pedalling.

How often do you change tyres. I put mine on 6 years ago (6000 miles) and it looks like they should last another 10 years (10,000 miles) if they carry on wearing at the same rate. That's once every 16 years. I think many of our forum members would be dead before they change their tyres on that...

When you switch on the bike and there's a non-zero throttle signal, the controller ignores it and will continue to ignore all throttle signals until it sees zero once, after which it'll respond to whatever signal it gets. It's a safety feature to make sure that your bike doesn't ride off without...

I doubt that anybody can repair the battery. Everything about it is bespoke except the cells. What's wrong with it?

If you had actually tried it, you would know why you can't do it like that.

Gotcha!

The controller needs to see a zero throttle signal before it'll give power with the throttle, so switch the bike on with the throttle disconnected, lift the wheel off the ground and see whether the wheel starts turning. Also, check that the red goes to the red, black to black and signal to...

But none of those methods work when you have a 9-pin connector, which is what OP has!

I've built several two wheel drive bikes, so if you need any more info, just ask. One thing you need to think about is the power from the front motor. You set the rear up with normal throttle and PAS. I would use a normal 15 amp KT controller with LCD for it. You can then use that motor on its...

Good point, but just to be pedantic, there's a 10% tolerance on the speed, so the actual illegal speed is above 17.1875 mph. Not a lot of people know that!

Two Q100Hs work very well at around 15 amps each. The drag from the motors isn't really noticeable. You can use a single pedal sensor and throttle as long as you use a common ground for both controllers. All you need is a branch off each of the signal wires to the second controller. In fact you...

I should have added Elastoplasts and antiseptic cream to the list for the cuts and burns that you get, but I never bother with those things myself. I just use gaffa tape if it's that bad.

You can grind 3 - 5 mm off the inside of the boss that goes onto the square taper to make a bit more room. It won't make any difference to the stability of the pedal arm.

They have a windscreen wiper type motor, like the Tonaro

This guy is selling one on Ebay and has another one. you could try contacting him. Ebay messaging doesn't like you exchanging contact details, so you have to come up with some clever ways of encoding them...

This is one of the problems of systems with sealed connectors. It's really tricky to find contact points for testing and diagnosis, which is why I prefer and advise people to use kits with conventional block connectors. Guys like me that fix these systems regularly have spare connectors with...

It says that the maximum continuous current is 20A. That 38A controller will exceed that, probably for most of the time. The BMS doesn't cut off until 60A, so you should be OK from that point of view, but I would think that you'll probably get cut-outs due to voltage sag if you run at full power...
