Some points:
An erratic riding style and ill-considered manouvers make not a thrilling home movie. I appreciate that you've attempted to make this an adrenalin rushing white-knuckle ride of gritty urban kool by speeding up the footage - or perhaps it was done so that the 9 mins felt only like 20 mins instead of 20 mins feeling like a lifetime - but it makes me think of a Buster Keaton film with nothing that made a Buster Keaton film good.
As a suggestion next time you should consider putting the camera on the spokes.
