Claim 14:
15. A non-transitory computer-readable medium whose contents, when executed by a friction detection system stored in memory of a controller of an electric bicycle, causes the friction detection system to perform a method, the method comprising:
identifying, from one or more sensors of the electric bicycle, an unsafe environmental condition at an environment within which the electric bicycle is traveling;
determining a friction condition for a road surface upon which the electric bicycle is traveling through the environment, by:
determining multiple force vectors applied to the electric bicycle at a current speed and tilt angle of the electric bicycle from motion data captured by the one or more sensors of the electric bicycle;
comparing the multiple force vectors to baseline force vectors for the electric bicycle at the current speed and tilt angle; and

determining the friction condition based on the comparison of the multiple force vectors to the baseline force vectors for the electric bicycle; and
performing an action in response to the determined friction condition for the road surface upon which the electric bicycle is traveling through the environment.
