Bakcou Flatlander SD

The Flatlander SD is a low maintenance fat tire bike for riders who cover long, mostly flat miles on gravel roads, two-tracks and trails.

Instead of a derailleur it uses a Bafang 750W rear hub motor with two internal speeds and 85Nm of torque, paired with a single-speed chain line. Fewer moving parts means less to adjust or break.

The 52V 20Ah battery can be paired with a second pack on the quick release modular rack. A spring fork, suspension seat post, 4 inch CST tires on 24 or 26 inch wheels and quad piston hydraulic brakes give a stable, comfortable ride. The On-Demand Program sets your speed class, and Bakcou Connect is available as an add-on.
