It's a folding lock that comes with its own holder, not a tool case. Here it is where you can see the Abus brand name. The picture says Abus Bordo, but other Bordos have a different holder.

I think a direct drive hub-motor would be a lot more reliable and suitable for that type of riding. All you'll get for pushing that much power through the chain and gears is a lot of inconvenience and cost.

I'm assuming that yours has the battery down behind the seatpost and the controller compartment underneath it. All you have to do is remove the screws in the plate on the side. Make sure that your screwdriver fits the screws properly. Photos of what you have or what your problems are always help.

Did you tighten the motor connections, like I suggested?

Right, I have one of those controllers. On mine, the brown wires are to reverse the motor rotation direction, but all they are is a jumper to make a CPU input high or low, so if yours has different software in it, it could be used for anything. It's worth checking whether connecting them...

There are several things you can do to get more power from it. Firstly, solder the shunt for 30% more torque, which will help you with hill climbing. You haven't given any details of what you have, so I can't advise you how to delimit it. a good upgrade is to get a 17 amp sine wave controller...

In theory the battery can be used on any Chinese 24v bike. I've never seen that connection system before, so not much chance of finding a bike that it fits, but a hobbyist might be able to do something with it.

You need to show us the battery and/or a photo of the bike. There are different versions.

You need to take some photos that show the connectors and wires so that we can see what you've got instead of a jumbled mess.

That's what I mean. 60W will be fine. Strip each wire back about 5mm, push the wires together so they're interwoven. Run around pinching the outside to make them more flat. heat up a bit with the soldering iron, then add the solder. keep the iron on the wire all the time while adding more solder...

Some of the older Wispers had trouble with the fuse holders melting. It's difficult to comment further without knowing which bike and battery you have.

You're misunderstanding me. Firstly, there is no legal limit to how much current you push through your 250w motor. You can use 25 amps at 36v (1000w) if you want. That's not illegal. Alternatively, you could up the voltage to 48v and use 20A for 1000W completely legally as long as you restrict...

Have the cut-outs stopped now then?

You can't believe anything it that listing specification. Clearly, it has been cut and pasted from an entirely different battery as it's for a 36v one. 250W or 100W makes no difference to the current if all that does is restrict the speed, which is what I guess it does. You need a wattmeter or...

You'll need at least 2 kW of output power to maintain a reasonable speed up a hill. The power quoted for motors is their rated power, not their output power. It's the motor controller that decides how much power you get, and the battery that provides the power. Another important characteristic...

I didn't need to oil the one I did. It was fairly new and I had to replace the gear change servo, which is a standard R/C servo, like they use in R/C aeroplanes and cars. I think I'd be tempted to use a motorcycle chain lube aerosol because they have agents to make the grease stay in place. Let...

Saltwater is indeed much more corrosive than freshwater. That's why they use a salt spray test to test for corrosion resistance in the auto industry. A 24 hour salt spray test is deemed equivalent to 10 years of corrosion in normal use. It's because salt water is much more conductive than...

That's not the full story. Like the guy that killed the woman, the cyclist had plenty of time to avoid her, so chose to steer behind her, but then, at the point of no return, she woke up, panicked and jumped back into his path. This happens to me very often when I use my bell or shout. I...

I've never yet come across a motor that can't give you all the torque you need. You're looking in the wrong direction. All you need is the right controller and a battery that can provide the power it allows. You haven't given us enough info to give specific advice. What size wheels do you have...

I've opened a G2, which is more or less the same. It's very straight forward to take the cover off the chain case. It was more than a year ago, so i can't remember how i did it, but it was easy enough to figure out. I remember that there was at least one screw that was either hidden or difficult...
