If it takes
The bike is only accelerating in the horizontal direction (you don't see people floating on bikes, besides in E.T., right?), so there is no need to resolve the force into components, and its safe to assume it is horizontal. Hence,
is the approximate acceleration of the bike given your data.
Note: I assume there was negligible friction, and air resistance.
