Need some wiring help if anyone has suggestions
 
Hey, new member. Just bought a bike called an eFlow Nitro. Shopped a long time before I chose it.

I am 6'3" and I needed to raise the handlebars about 4 inches to work with my body ergonomically.

The problem is the wires to the brakes (which cut off the power), the connector to the throttle, and the connector to the display are too short when I raise the handle bar.

I am looking for a way to extend these wires. CurrieTech -- the maker of the bike does not offer a solution. They sell only the "junction wire" which is only one length. No extensions.

If anyone has any ideas, please let me know. This is the perfect bike for me other than this. I live in Los Angeles if there is any tech out there who can solve the problem.

Thanks so much for your help in advance!

A lot of little solder connections
 
This is not a terribly complex problem but the solution is not all that elegant. You can (have someone do this for you or) cut open the wires,add length, and solder them back. Doing so will preserve the connectors that came with the bike,but give you longer wires. Buy heat-shrink tube that can cover your wires and the area around the splice. Solder your extra length of wire to one end of the wire you cut and then the other. Each brake may have a double wire or a single. You have to add to every single wire you choose to lengthen, and add heat shrink tube so that your strands don't touch each other. The display may have 8 wires or so and you must match the wires up as designed, or it won't work. The throttle,I assume, has 2 or 3 wires which must be connected correctly. The existing wires may or may not be color coded in a way that makes it easy to connect them correctly.

The "wire harness" part you mention might be useful in the following way: if it has wires for all your parts and you buy an extra wire harness, you could cut upper connector off one,lower connector off the other, and end up with the right amount of wire when splicing together. If so, you'd end up having to solder fewer times BUT you'll have to somehow identify every single wire that is to be soldered and make room for your solder, your tubing (to keep wires separate which prevents short circuit) and the doubled up wire where you made the solder connection.

Either way the process will likely make the bike non rainproof if it was rainproof before. (Meticulous use of the right kind of glue at connections may be enough to waterproof the connections)
