nice progress on the bike :D
Looks a lot better ^_^
The power appliedfrom pushing a or d is kinda over kill, applying it on a 'wrong' moment makes the bike go super athelete on ya hehe
Bike itself looked nice.
Might be an idea to remove the treee, and make an option to do tricks in the which could get you points :D (air time, summersaults, etc etc)
