A full-feature fixie that's great for city or campus riding. Built with a High Tensile Strength steel frame with internal brake cable routing and threadless fork for worry-free riding mile after mile. Equipped with 45mm Deep V double wall alloy rims, alloy Sealed Cartridge Bearing hubs, 700 x 32c tires, Forged alloy 3-piece cranks with sealed cartridge bottom bracket, low-profile BMX pedals, and alloy hand-operated caliper brakes, alloy handlebar and alloy threadless stem with 4 bolt cap.

Your best-of-both-worlds bicycle
There's no other feeling like riding fixed gear. You're bound to the wheel, connected to the bike, and rewarded with instant response to your pedal input. If freewheel is more your speed, switch to single-speed bike with a flip of the rear hub. Pro-tip: think of fixed gear as your adrenaline-packed ride and single speed its relaxed counterpart. Both are simple but provide different pedal stroke sensations.

Harper Plus is equipped with sealed cartridge bearings that protect delicate bike parts from gunk in the road, require less maintenance than loose bearings, and increase the longevity of your ride. Its threadless steering system lightens your load, gives less flex and more precision, and is much easier to maintain or adjust as needed.

For the minimalists
Ride in style. Harper Plus is designed to match all things modern with its internal bike cable routing, stainless steel spokes, and sleek, geometric diamond frame.
