Bikepark is a physics-based BMX game for riders made by riders.

It's got an arcade style to it (Think Matt Hoffman's Pro BMX). At the moment it's a free roam aspect where you create your parks and bikes and shred.

The game was to be updated continuously and eventually go to Steam as a shareware game, but like many indie games, it seems the developers moved on. Their website and Facebook are gone so we now consider this abandoned.
