2018 Retrospec Mars-1 Diamond Single-Speed

The Mars single-speed city bike is fully equipped for a mind-bogglingly complete ride. Yes, it’s single-speed, and no, it’s never lacking in anything. Ride across campuses, down city streets, and along bike trails simply and stylishly.

The classic diamond frame is forever timeless and extremely reliable. Hand-built, tig-welded, and high-tensile strength steel, the Mars diamond frame was built with you in mind. It’s shock-absorbent for a more comfortable ride and it’s extremely durable for a long life. The shape and position of the handlebars encourage upright riding, ultimately better for your back and comfort level.

The Mars city bike flaunts a mid-century-inspired style, complete with a chrome headlight, classic bell, matching fenders, and a polished rear rack. It also comes with plush vegan grips and saddle for comfortable riding. Front and rear brakes give you back all the control over your bike, your speed, and your stopping while Kenda commuter tires continue to grip the road, even in damp conditions. The tread of these tires has water dispersion grooves, so the tire can always be in contact with the ground.

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.
