2 options
1 It was a crash on the road, involving a bicycle. Possible also indication that there was another (larger, engine powered) vehicle involved, rather than rider error. (Think what your intial thought would be if it was just “bicycle crash”.)
2 It is a crude attempt to imply that he was out “roadieing” ie, lycra’d up, head down arse up, wobbly skinny tyred bike with useless brakes*, only out for fitness/recreation rather than transportation; and therefore due less public sympathy.
I’d like to think it is the former option, but I am an optimist.
*as described by an average non cyclist who doesn’t understand how bikes work.
