Prior to ending operations in 2019, Bieber Transportation Group provided intercity commuter bus service from points in eastern Pennsylvania to Philadelphia and the intersection of 8th Avenue and 39th Street in the Midtown Manhattan section of New York City.

[1][2] Bieber also offered tour bus service to domestic and international destinations, including casino excursions to Atlantic City.

[3][4] The company offered charters for groups for single-day or multi-day trips along with weddings, airport transfers, casino excursions, and cruise ports.

The fleet consisted of tour buses manufactured by Motor Coach Industries, Prevost, and Van Hool that can seat between 33 and 56 passengers.

Amenities on the buses included heating and air conditioning, restrooms, PA system, DVD players, and AM/FM CD stereo.
