Brompton - M3L - Tempest Blue - Balfe's Bikes

Warm tip: there are two kinds of small cloth speed, respectively in the three speed and six speed, accessories are basically the same, only the colour is different. 1. Casual speed riding flat roads, the car is lighter, the original 54T crank gears for most people 54T gears or some heavy feet (laborious and unpleasant). This way the bike can be ridden and the Bub can climb gentle hills. The bike is a good choice. The standard 5OT crankset can only climb small gentle slopes and flat roads, and the heavy gears are not used.
