Harper Coaster is the perfect bike for the rider who wants the sleek profile of a fixed-gear with the refreshing ease of a cruiser. The really special thing about Harper Coaster is that it has a built-in coaster brake. It's a traditional fixie platform fitted with a foot-operated rear coaster brake for a clean look with no brake or gear cables. Built with a High Tensile Strength steel frame and fork for worry-free riding mile after mile. Equipped with 30mm Deep V double-wall alloy rims, Kenda Kwest 700 x 28c tires, Forged alloy 3 piece cranks with sealed cartridge bottom bracket, low profile BMX pedals.

- We guarantee our hand-built, tig-welded, high-tensile strength steel frame for life. Ride with bar-spin clearance, a flat top tube, no toe overlap, and horizontal dropouts, perfect for the commuter’s lifestyle.

- The coaster brake is the most straightforward brake to control. Simply pedal backwards to come to a stop. There are no levers or cables to deal with. This ultra-sleek silhouette doesn’t require significant upkeep because there are so few elements to it.

- Harper Coaster single-speed is also equipped with riser handlebars. Sit upright and relaxed while you ride—you’ll be more comfortable in this position.

- VP freestyle pedals and KMC chains are always reliable while the 30mm deep-V rims and thick Wanda tires facilitate an extra smooth ride.
