Ebike cable extensions Greenedge CS2 step through

With my other half enjoying his greenedge bike from a couple of years ago, I have recently purchased a CS2 step through for myself.

The problem we are now having is I am quite short, and my arm length is short and I have various back problems. With my manual bike it took a lot of changing handlebars and positioning to get it comfortable in long rides suitable for my body/health.

My local bike chap has already replaced the handle bar post to raise up and tilt the handlebars towards me slightly, and put longer brake/gear cables to allow for this. The position still causes pain on longer journeys but if there was a way to extend the electric bike cables by just 3 inches then I could tilt further and get the riding position perfect.

 

is there such a thing as longer cables, or if I bought an additional wiring loom, could a suitable expert make a little extension of 3 inches to fit in between the existing plugs on each cable. the fact there are connectors on the cables would imply this shouldn't be rocket science - my blokes cables doesn't have that feature at all they are all in one jobs!

 

I do have experience in splicing and soldering various computer and electronic cables, so even if there was a wiring guide somewhere I would have a go myself but as it is I may end up having to send the bike back if I can't get the position right.

 

Any advice would be appreciated

 

Thanks

Which cables need to be lengthened? There's nothing to stop you cutting any of the electrical cables and splicing in an extension. I do it just about every time I build/convert an electric bike. Don't cut the cable to the display when the battery is on the bike because one of the wires is connected to the battery and will short when you cut through.

Brilliant that's encouraging - there are two cables I think, possibly a third (will run out and check in due course), all of which need extended by about 3 inches.

My bike guy didn't want to take the risk of trying it as he is not really an expert in e bikes and thought different manufacturers would have different colour coding or wiring configurations in each and wouldn't know what to do.

What are the specifics of piecing in reliable extensions? Is this someone I could pay online to do for me and ship the extenders to me or would someone need to have the bike in front of them?

 

Many thanks, for giving me hope!

4 cables, want to insert about 3 inches in length inbetween each of the black connecters that all say Juliet on them?

All you need is wire, side-cutters, heat-shrink tube and soldering equipment.

 

The throttle cable has three wires in it.

The Brakes have two or three.

The display has four or five.

 

If you bought a length of 5 core (22 gauge), you can use it for all.

Cut the cable and strip back the insulation on each side until it looks like the Ebay photo above.

Do the same to the extension piece.

Slide on some heat-shrink over the whole cable and push it along out of the way.

Cut some thin heat-shrink for each wire and slide it away from the joint.

Solder a pair of the thin wires

Slide the heat-shrink over join and shrink it.

Repeat for all wires in the cable

Slide the thick heat-shrink over the complete join and shrink it.

Repeat at the other end of the extension.

 

That's it.
