There's a recent thread about it. To produce 160Nm torque at say 7.5 mph with a 29" wheel, it would be outputting 1510 watts. Let's say at an efficiency of 70%. That would be 2157 watts from the battery or 90 amps. It's puny 8Ah battery would last 5.3 minutes if it could manage that sort of...

Turn the bike upside down. Unclip the motor cable and wiggle the connector apart that sits under the right side chain-stay Wiggle off the black plastic cap and push it up the cable. Straighten the cable so that it's in line with the axle for the first inch or so. Undo the nut completely until...

The wite wire is the speed sensor. It goes to the white wire on the white 3-pin connector with red, black and white wires. that has nothing to do with your problem. It only affects the speed display. Your photo, as always, us very fuzzy, but it looks like the motor connector isn't in far...

Good GPs are very few and far between. They don't like to refer you because they have to pay. I think i must have seen 30 different GPs since 1982. I wouldn't trust any of them to sort me out. None of them were anything like those ones you see on the TV. None will listen to what you have to say.

I went for a ride today. Unfortunately, i had to go past a local spot where people congregate to go for a walk up a hill. It's a country lane. There is a car park on it,but I guess either it iver-flowed or people didn't want the hassle of getting in and out. The end result was that there was a...

B ad luck. That wire could be for remote switching or anything else. You need to follow it and see where it goes.

One case is unlikely to be representative of the whole population. You also have to consider that we cyclists are likely to have much better immune systems, have a lower BMI and have stronger cardio-vascular systems, so we're not representative of the general population. One medical research...

The motor suposedly has the capability to deliver 80Nm, but how much power you actually get depends on how much power the controller allows and how much the battery can provide. You'd need 840 watts of output power to get 80Nm at 7.5 mph since power = torque (Nm) x RPM and 15 mph is approx 201...

Before buying any battery, you need to confirm that the present one is only connected by only two wires, otherwise you're going to be disappointed.

There are two ways to get more speed. You can either buy all new electrics other than battery and motor (about £80) and wire them in or you can do the speed sensor dodge. The new controller will give the option of more power too, but I don't know if the 17A or 20A ones fit in the space...

I don't think it's anything to worry about. I've had that before. it lasted a week or two before it sorted itself out.You need to keep it warm long enoughfor it to expel the moist air.

They're talking about fractions of a degree out of paralle when you spread the frame. That's got nothing to do with OP's problem. what was your misalignment and how did it come about? I had to spread my frame so far to fit a Xiongda motor that the two arms were very noticeably not parallel, and...

That's a good question. As far as i know, they're unbranded AKM128s. You can get them from BMSBattery, Greenbikekit, Topbikekit and others. Recently, they've started selling branded AKM128s, which are identical. There are three versions: the C has the cassette spline and the other two are for...

The number of prongs is not important. They normally only wire the outer two anyway, and if they do use all 4, the wires go two into one, so you still end up with only two wires. What's important is that they're the same way round. Never trust the markings. always test with a meter. Regarding...

The LCD should display watts. Current = watts/volts.

You can get bags that go under the saddle. There are all sorts of sizes and shapes. Some are more horizontal, some vertical and some in between, or there's the traditional style that hangs across the way.Use a hot soldering iron or similar to poke a hole in the bottom for the wires...

The upside down wouldn't have done any harm. Sometimes a bit of air can get in the pipe, which makes the lever go spongy, but bike brake cyinders are self bleeding, so the air comes back out after you press the lever a few times. that's nothing to do with your problem though. It's probably just...

64V and 48v Lipos- 5aH 6S hard-packs. There wer 8 (4S2) powering both hub-motors and another three (3S1P) for the middle motor. The grounds were common so that I could use one throttle to work all three controllers. Imagine a normal Ebike running with 36v and 15 amps. Multip y the power by 1.6...
