Claim 7:
8. A method performed by a friction detection system stored in memory of a controller of an electric bicycle, the method comprising:
receiving information captured by one or more sensors of the electric bicycle;
determining one or more metrics associated with a contact friction currently applied to the electric bicycle by a road surface upon which the electric bicycle is traveling, 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 one or more metrics 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 estimated contact friction currently applied to the electric bicycle.
