Do you mean "fickle"?

You've nothing to complain about. You've had your best year already since Brexit became certain, and we've hardly started. All the prophecies of doom were completely unfounded. Don't think that the boom is down to the virus. I just bought anew motorbike. The dealer said this year has been...

What's going on in the football league? Last week, nearly every player, pundit, captain and manager were wearing BLM badges and kneeling in support. All the players gave up their names and had "Black lives matter" on their shirts instead. Anybody that said that the football league wasn't in...

Don't forget that there are three plastic gears in a hub-motor to share the load that would be done by one in a crank motor.

They might feel the same at some speeds, but there is a different max speed between level 4 and level 6, and the low speed current is higher on normal than it is eco, so you get different acceleration. You could use the argument that when you're pedalling at 30 mph, all 18 settings are the same!

There have been loads of cases of chains snapping on this forum, along with smashed derailleurs. The Bosch CX is noted for its chain suck that smashes chains like they're made of cheese. It's created a whole industry of after-market devices...

With the red and blue bridged, measure the voltage between the red and black PAS wires. 5V tells you that the controller is switched on and should be working. Don't worry, by measuring and testing, we will be able to get to the root of your problem. If I had your bike in front of me I'd have...

It depends on how hard you're pedalling and how fast you're going. I used to use 480 watt-hours to travel 14.4 miles at a modal speed of 18 mph, and climbing about 100 meters, so 19 miles would take 633 Wh. Your battery has 884 Wh, so what you're getting sounds about right, especially with three...

That's not easy because a lot of it is hushed up. I was at a dealer a couple of years ago during the Bosch CX water ingress pandemic, and he showed me a pile of 5 or 6 Bosch motors waiting to go back. He told me that it wasn't just Bosch either. Don't forget, these people have built a business...

With everything switched on, measure the voltage between the red and black wires on the 4-pin connector that goes to the control panel. If you get battery voltage there, unplug the control panel and bridge the red and blue wires. That should then give you level 1 assist when you pedal and the...

This is a bit of a problem. I can't understand why some people just can't be honest. Over the years, I've had a lot of contact with dealers and people in the trade, so I hear lots of interesting stories and stuff. I can say categorically that people have been coming on the forum, recommending...

You might be able to get some basic function from your bike if you disconnect the LCD and bridge the red to the blue and the green to the yellow. That should show that the motor and controller are working. If it sparks when you bridge the red and blue, it could mean that there's a short in the...

To operate the three speed switch, you join the black to one of the others to get a 10% boost, and black to the remaining one to get restricted speed. You have to try to see which is which. Nothing connected is normal operation. The boost speed is done by altering the timing. It optimises the...

I told you, the flux capacitor is swollen. It could blow any time soon.

You didn't say whether that flat connector is connected to the LCD or the motor. It looks suspiciously like the motor one because the blue is normally next to the red for LCDs. If connected to the LCD: Pull out the hot melt glue from the back of the connectors. It doesn't do anything anyway...

I don't get you guys with all these weird things. During my 10 years of ebiking, I must've fixed 100 punctures on my own and other people's bikes. I've never had one that I couldn't fix at the roadside with a simple puncture repair kit. One time, when I hit a pot-hole on my road bike, I got 3...

Any answer you get will be meaningless. It's just a question of how hard people pedal on their bikes. Some switch the power off completely. As a general rule, for a not too fit rider on a ride with a moderate amount of hills, you get about 30 miles from a 36v 10Ah battery. Range is directly...

80% batteries will be useless on an ebike, especially 1.8 and 2,0 Ah ones. If you're going to build a battery, use decent cells and do it properly, otherwise buy a cheap battery from Ebay.

Only if you have the flat type connectors. If it's the cylindrical sealed ones, it's no.

14g spokes give a more comfortable ride, don't break so much and don't come loose. If you don't mind spending money, you can get the butted spokes with 13g ends and 14g down the main length. I've never bothered with them and I haven't had any problems. Spoke thickness is counter intuitive. It's...
