Impromptu guide to doing stuff fast on a bike (volume 1):
1) ride a bike. Go bush with it.
2) unintentionally upset a snake by riding into its personal space. For best results, find a big one
3) Ride away from snake. Snake will follow because snakes like a challenge
4) Accelerate in vain followed by what sounds like an angry snake, 267 of its closest snake friends, a mountain lion, a swarm of wasps, a couple of those aliens from Edge of Tomorrow, and a kraken
5) fly through previously formiddable looking rock garden. Barely notice
6) break speed record previously set by a light aircraft
7) profit
