I was reading this article on Group Riding and saw the following: So is it advisable to keep, let's say, a small plank under the seat? Or even carry it around?:-s Also, I have to admit this is the first time I've heard about bitumen melting under a bike stand, so pardon my ignorance. What happens to the bike when this happens? Is it going to topple over? Or is the bike going to become stuck there when the bitumen cools?
