That's interesting. I found the same. I only had to feather the brake and it squealed like iI was doing an emergency stop. You should have seen all the pedestrians scatter! I sometimes wish I hadn't fixed it. That reminds me, there's another fix OP can try. Loosen off the two screws so that...

You have to make sure that the hose is uphill all the way as well, otherwise any air gets stuck in the bend. that's a good tip but I doubt that it's air causing OP's problem. Air makes the lever spongy, which is normally obvious.

It's very common for brakes to squeal and make other noises, especially after it's rained and even worse in the winter when you get salty water on them. Some pads and discs are worse than others, so try different ones until the noise goes. Discs and pads don't cost much.. If your brake keep...

Low potential brake connectors are for normal brake switches. the high potential ones are for special brake switches that you're unlikely to see, and the the three-wire ones are for hall sensor switches.

The question we need to answer is whether anyone would enjoy the same bike more with a modern Shimano 8-speed, the new Shimano gearbox thingamabob, Shimano XT 9-speed derailleur gears or anything else. Then there's another question whether anybody would enjoy the same ride more with an entirely...

It was misty last night then sub-zero this morning. Freewheels and cables can freeze in these conditions.

electric brake is for a hall sensor brake switch. If you have 2-wire brake switches, you connect them to just the white and black wires. i don't get what you're saying about the brakes being already connected because the picture doesn't show any 2-wire connectors for the brakes. Where did you...

4mph with the throttle is normal because that's all you're allowed to have legally. Does the pedal assist work?

Controllers either work or not. They're all solid state, so nothing to break down. The only faults I've ever seen are blown MOSFETs, which stop them dead, melted tracks from running too much current, other blown parts from connecting the wrong way round, and blown 5v regulator from a short on...

That's a good video. He uses exactly the same method as me. I like the tapered spoke idea to insert the nipple. I've been using a 13g spoke to insert 14g nipples. It just hooks in to the first thread in the nipple so you can then use it as a driver. That's not as good as the tapered spoke. A...

If you have enough mechanical nouse to install a kit, you should be able to figure out how to build your own wheel. Many on this forum have been in the same position as you and they completed their wheel build successfully. Sheldon brown gives a very clear instruction on how to do it. If you buy...

328 rpm will be perfect for what you want. You either use a 36v 260 rpm one at 48v or a 48v 328 rpm one. 260 rpm might be OK for 30 km/h, but not for 35km/h. You need a motor that spins to 1.33 times your modal riding speed to get good power at that speed because the power ramps down to zero as...

Do you honestly think that Oxygen, one of the longest established brands, would use sub-standard batteries in their bikes?

That's still a bit low for what it should be, indicating that all is not as good as it should be in the battery department, though I doubt that it has anything to do with your problem.

Lunar bikes or Em3ev are probably the only places you might get one. Neither are in the UK. You have a 100mm BB. Why do you want 115mm?

Power and voltage designations are not important characteristics. Motor speed is proportional to voltage. The same motor will spin 33% faster at48v compared with 36v. Power is proportional to current and voltage, so a motor will give 33% more power at 20 amps compared with 15 amps, and 33%...

You can use just about any controller if you know basic wiring and electrics. If E-bikesdirect doesn't work out, come back and ask again.

It's a nice idea, but I'm reasonably sure that it's not going to work. Go to a couple of electric bike shop and try folding and carrying some folding bikes. If you still think it's worth it after that, try a rest ride to see if it feels right for the rides you plan.

Are you absolutely sure that the lights dont go off while the motor cuts, then come on again. If they do, try re-soldering the wires on the back of the key switch inside the top of the battery. They sometimes have dry joints that break down under full power. Use plenty of heat to make sure that...

I'm not triggered. I'm trying to help you, but when you use words that I can't understand, I have to ask you what you mean be cause it might be something important. You have described the throttle, which I can now understand. Nothing will work when you don't have battery voltage (41.5v) on that...
