Hey, I suggest the option to unlock a bamboo bike, something like this… http://calfeedesign.com/products/bamboo/
Also, have the road lead through a section with a pack of Panda bears that will start chasing you when riding the bamboo bike.
Good idea, riders like to win new bikes and this one also deserves its place. However, there are license issues?
I would hope products featured in the game are sponsors thereof!?
