MOTOBECANE 650 touring bicycle frame 50cm 3895g 121.5mm BSC vintage bike

This classic French steel chassis from Motobecane is designed specifically for 650B wheels, making it an excellent foundation for an authentic touring bike project. Engineered during the golden era of French cycle manufacturing, this durable steel frame offers the traditional compliance and longevity required for fully-loaded randonneur journeys or vintage-style commuting.

Key Mechanical Characteristics

Constructed with durable steel tubing, this frame features a 50cm seat tube (measured from the bottom bracket center to the top of the tube). Designed for classic cantilever or caliper setups, it provides the stable geometry and reliable handling characteristic of vintage Motobecane touring bike frames. If you are planning a complete classic build, you can also view our ARROW 650 touring bike frame as a complementary reference for classic geometry.

The frame exhibits normal cosmetic signs of age, including surface paint patina and light oxidation, typical for a used vintage bicycle frame. The detailed product photographs serve as the primary visual description of the structural condition, paint finish, and lug detailing.
