The problem with those cheap kits is that they don't have the functions that make a bike nice to ride. I'm assuming that you don't have an LCD with 5 levels of assist. If that's so, the pedal sensor might allow more power than the throttle, but it's pretty useless regarding power control. If...

So, you bought the cheapest hub-motor kit with the crappiest controller that doesn't even have a torque sensor, then you condemn all hub-motor sytems? Brilliant!

Rims are not expensive, but if you want to use the spokes again, you'd have to find a eim with the same ERD. you should be able to get a cheap rim and spokes for about £35, then you'd have to build the wheel, which would be another £30 if you got a shop to do it. As ever, you guys never show...

That's perfect fo dilveroo.

I must admit that I find the Spin Cycle very aesthetically pleasing, and I'd be proud to ride it. I think I'd change the brakes first, though! It's a development of the cramk-drive bike that i built before kits were available:

I guess you don't know of any examples then. Sorry to spoil your dreams, but better that than make you waste your money.

I asked you for examples that you think are OK so that we can try them out. Where's the elitism? Your're right about sour experience though. When anybody puts their money down in the hope of having a long and pleasant ebiking experience and the thing packs up after a few weeks, it leaves a...

The listing of the battery should show the maximum continuous current that the battery can give. It needs to be at least 20 amps for a 20A controller. The controller will give 20A at 48v to the motor, which is 960w. The motor will then give out about 620w of output power maximum. You only get...

Did you have it on level 5 on the LCD? Can you show us exactly the listing of the kit you have?

Vanity, mainly!

There's no relationship between the two. best would be to show us what controller, motor and battery you have in mind, then tell us what you expect/hope they will do for you, so that we can advise you exactly what you need.

That's an excellent question. Our Chinese friends are not very consistent when they use these colours. Red goes to red. That's easy. According to other listings of similar sensors, blue is ground, so it goes to black, and yellow is signal and goes to whatever third wire you have. If it doesn't...

You need to be more specific about which exact motor and controller you have. The controller decides the power, the motor has to be able to deal with it and the battery has to be able to supply it. All three have to to work together. A battery that can supply 1500w can probably work with any...

They can't make enough to satisfy the demand. Of course they'd put up the price. Wouldn't you? they're a business, not a charity. I was watching Silver Brittania coins from Bullion by Post. They were selling them two weeks ago for £29. Last week, due to misinformation after the Game Stop...

A good bulk? How many have you seen in? Can you give us some examples? The only ones I know are the Magic Pie, All in One, Bionx, Copenhagen Wheel, iMortor, Keyde, Flykly and a few others. None of them have special cooling fins and all are problematic apart from the Bionx.

The sensor is very common, but the connector arrangement isn't. You'll be very lucky to fond one like that. If you're very dextrous and have two pairs of small pliers, you can crimp on new connector pins and clip the pins into the connector blocks you have. To get the pins out of your present...

In that case you have a short circuit in your wiring or the light, or somebody has done something weird with the lighting circuit, like adding a relay. You should be able to follow the live wire to the rear light to see where it's getting its power from.

There is nothing governing the speed of a hub-motor inside it. It's the controller that does the speed regulation. The 9 wires are 3 x motor phase wires, 3 x motor hall sensors, 5v supply to the sensors, ground and speed sensor. Hub-motors have a maximum speed by design that depends on the Kv...

I don't understand what you mean. Which switch/s are you using to switch each light on and off.
