I went to change my front sprocket and rear sprocket as well as the chain. When doing this I had to remove my speed sensor to get to the front sprocket. I realized that one of the wires was broken (Redish orange) and once I had cleaned everything then I put it back together not thinking of it. Now my bike won't start I don't know what it is. It just doesn't start and it makes a beeping noise when I try and shift gears. Any questions?
