I'm thinking about getting a new bike. Yet, I have no idea whether I should get a cyclocross or roadie(I will not be riding off track. 100% paved road, but will do simple tricks like bunny hopping and wheelies) Also, should it be single speed or what? I will be circling the island where I live next month but will just ride in the cities afterwards. Which (brand, type) would you recommend? Thanks.
