SEPTA allows bicycles on many of its transit services, but there are specific rules and guidelines that users should follow. On Regional Rail trains, bicycles are permitted at all times, except during peak hours on weekdays. It is generally advisable to avoid bringing bicycles onto the trains from 7:00 AM to 9:00 AM and from 4:00 PM to 6:00 PM on weekdays. On buses, bicycles can be transported if the bus is equipped with a bicycle rack, and riders are typically encouraged to board at the front of the bus while placing their bicycle on the designated rack. Additionally, bicycles are allowed on the Market-Frankford Line and the Broad Street Line, but there may be restrictions during peak hours as well. For more details, it is beneficial to consult the SEPTA website, where the most current policies and information can be found.
