According some aspects, an automated bicycle emergency braking system may be retrofitted to a commercial pedestrian bicycle to provide emergency braking functionality. Aspects described therein detail a light-weight and consumer affordable automated bicycle emergency braking system for improving pedestrian bicycle safety. Aspects described therein relate to sensing of a bicycle's surroundings for potentially hazardous objects, identifying a potentially hazardous road condition, determining whether to engage a bicycle's mechanical braking system, determining how long to engage a bicycle's mechanical braking system, and disengaging a bicycle's mechanical braking system until determining confirmation of resolution of the pedestrian bicyclist's safety regarding the identified potentially hazardous road condition.
