Decided to take one of children for a long ride. But first had him follow my lead and wipe the entire bike down, checked every bolt, fender, cable, chain. Just to show him that a little pre-inspection goes a long way into safety.
We found a lose screw on the rear fender of his bike, a chain with a little too much slack on mine. 5 min of wrench time, and we had ourselves a wonderfull 12 mile ride.
