The Mars three-speed diamond city bike embodies clarity and refinement. With an internal 3-speed hub and a lightweight and very durable steel frame, this bike is just about unstoppable.

This bike is equipped with a Sturmey Archer internal hub. Not only has Sturmey Archer been around for over a century, but they’ve also managed to maintain their reputation of excellence throughout it. The internal hub protects the fragile elements from damage and dirt. An unexposed drivetrain means less upkeep over the lifetime of your bike.

Along with the Sturmey Archer three-speed drivetrain, this city bike uses a RevoShift grip shifter. Switching gears with this mechanism is easy and feels natural. Since it’s integrated into the handlebars and grips, you never have to compromise your focus on your ride, which in turn keeps you safer.

Hand-built. Tig-welded. High-tensile strength steel. Oh, and lightweight. Those are all traits of our extremely durable Mars diamond frame. Its classic shape compliments its undeniable comfort and lasting durability. The progressive geometry encourages an upright riding position, which is ultimately better for your back and neck.

To complete the vintage-inspired look of our city bike line, this three-speed diamond frame is trimmed with a chrome headlight, a mid-century bell, matching fenders, and a polished rear rack. Cushioned grips and saddle make your ride more comfortable, regardless of how far you’re going. The Mars city bike is also equipped with front and rear caliper brakes, keeping you safe and in command of your journey, how and when you stop. Kenda commuter tires will prevent slipping, fully gripping the ground even if it’s wet outside.

We strongly suggest that you take your bike to a professional bicycle mechanic to be built and/or checked out. Incorrect assembly of your bike could result in premature wear and/or failure of individual components. The brakes and derailleurs are not yet set up and need to be properly adjusted in order to stop and shift correctly.
