There's no legal limit to how much power you can use. I already got someone a letter of apology from the police and his bikes back when they seized them because they thought they were using too much power. They didn't even need an LCD. They had one of those inductive current measuring devices...

Have a look at the label on the controller. If the designation number starts with SVP, it's a sinewave one, so should be quiet and smooth. If it starts with ZWS, it's a square wave one, so more noisy and not as smooth. I never noticed much difference in the settings except when running...

That looks like a Tongxin motor. Sorry to mislead you. I should have read the thread from the top. When you mentioned six screws, I assumed that your motor has a side-plate held on by 6 screws because we don't see your type anymore. I haven't seen one of those in about 10 years. The side screws...

Why are you making things difficult for yourself? You don't have to squeeze anything into your existing battery case. Chuck the battery and the rack. Fit a normal rack and bolt the Greenlance battery carrier to it. Yose even sell a 17Ah rack battery that should bolt straight on for £265, though...

Show some photos.

Don't let the motor give power when it makes that noise, otherwise you can blow the controller. It's a connection problem between the controller and motor. Make sure that the motor connector is pushed in ALL THE WAY TO THE LINE, not just in tight, then have a look at the wires coming out of the...

If the battery has only two wires, you can use any 36v battery you like, or you can get a 48v controller set and a 48v battery to give more power if you want it. Yose and Greenlance are good suppliers of cheap batteries. We have a 10% discount code for Greenlance. I think it's PEDELECS10. E-Bike...

The one I see has coloured wires going into it!

Why don't you pedal the bike up to the motor's maximum speed and give us the data on watts vs speed, so we can see where the ramp is and when it ends? I just can't understand what you're telling us. It's all so imprecise. What size wheel is it in?

You missed out one. It's the large flat white one. Does it go to the motor? Now we need to see everything on your handlebars. I just fixed one very similar to that, which had a blown controller, but the owner only wanted it to run from the throttle and the front light to work. Unfortunately...

You will need to extend the wires from the battery connector, so solder on a pair of 14g wires, run them to wherever you want to have the controller, then solder them to the connector's battery wires. If ever you need to replace the controller it's quicker, cheaper and more reliable to solder...

No, that's normally even worse.

The question is how many watts show when it's doing 15 mph, 18 mph and 20 mph. If the watts go down, you're speed-limited by the motor windings. Surely you would have seen that already?

Just unscrew the 6 screws, remove any nuts on the axle that side, then tap the axle through from the other side with a soft mallet or hammer and block of wood.

We've got no chance of helping you from the information you've given us. At the moment, you've just shown us a birds nest with no indication of which wires are coming or going. You need to first of all list all the cables coming out of the controller with the colours of the wires, then you need...

I looked at the video again and came to the conclusion that the movement was more likely to be from further up than the forks, but he didn't show that part of the bike. The main point is that the bottom of the fork doesn't move, but the top does. This is consistent with play in the headset. He...

It looks a lot like fork bushes to me. Are the forks old? Are you sure you couldn't feel any movement when you took the wheel off and pushed the forks backwards and forwards, like I asked you to do before?

That's what I said. It's you that seems to be confused about having to do settings or something.

Many times, but that was before I worried too much about legality. After-market ones are set for the world market, so you have to do set the speed limit, like any after-market controller. OEM ones are already set just how you want them. When you buy a KT controller with throttle, speed sensor...

Maybe the centrifugal force from the fast spinning is jamming your clutch. Which motor is it? You can tell if the motor is working if you set the display to show actual power taken from the battery. If watts is zero, the controller is not sending any power. If you see around 1 amp (36w at 36v...
