Thank you. Sounds easy and my saddle bag should accommodate it easily. For that price I don't mind a few wires.Penny dropped.
they fit to the handle bar with a rubber O ring. very easy to fit, and remove.
The biggest problem is the cable and battery size you will need some where to put the battery, I put mine in the saddle bag and wrap the cable around the top tube, not elegant but it works.
A top tube bag just behind the stem would be better.
