The cyclist in full reflectives / hi-viz, with good lights, who belts the length of the Shore from the King's Wark to Cafe Truva on the pavement every morning about 6.45 - which means he's weaving his way through the folk waiting at the bus stop outside Mimi's at speed.
I know the Shore's setts are a frame-cracking, teeth-rattling, light-loosening pain, but if I can ride them on a road bike, he can ride them on a MTB with suspension forks. It's not like the road's busy and scary at that time of the morning either - it's almost always empty when I see the guy.
Hope he grows up and uses the road before he hits someone. It's bad enough passing people at that stop on foot without them stepping into your path absent-mindedly.
