I have a 2015 Raliegh Tekoa iE bike. Awesome bike, but has no battery, or anything but the 4 wires coming out of the frame. Saw some replacements on Amazon but nothing that shows the 4 wire hook up. The battery set ups are expensive and I want to get the right parts as to not ruin the electronics of the bike. If anyone knows what I should get or where to get the replacement parts for the bike, I would appreciate it. Here is a picture of what I am talking about.
