The dyno hub is on a 700c wheel, and it will move between the bikes, depending on conditions and activity.

Rear - I want to mount to the seat post. I do not ride with a rack. I am thinking of a short bar with two lights attached which crosses the seatpost like a T. I can have a permanent device attached to the seatpost, it will be on both bikes.

Front - I want something like the Minoura Swing Grip. Again, I will have a receiver on both bikes.

Wiring - the wiring into the hub and the lights will be soldered. The connectors will be in line, just some plugs, couplings, whatever.
