Rider
To Rider's annoyance, the man responded to her demand by smashing up a piece of concrete and throwing chunks at her, clearly intent on damaging her precious bike. Fortunately, she was just about able to avoid having her bike hit, even using her leg to kick away one of the incoming pebbles but, even for her, dodging fast-moving rocks on a bike was extremely difficult and, sooner or later, one would hit its target.
Realising that she couldn't win this race fairly, Rider allowed herself to slow down and turned at an angle, aiming herself so that she would cross his path. Then, as he crossed her path, she materialised her nails before throwing them both whilst keeping hold of the chains, aiming for the spokes of his back wheel. If either nail managed to hit, he would certainly crash as the nails got jammed in the fast-moving spokes.
