The Retrospec Mars seven-speed city bike is designed with commuters in mind. An unbeatable opponent is produced from a union between our lightweight, heavy-duty diamond frame, top-of-the-shelf Shimano drivetrain, and advanced component set.
The Shimano Altus 7-speed drivetrain will conquer all kinds of terrain with you. Whether you’re riding on flat or hilly trails, smooth or rough roads, or paved or dirt paths, you can count on this system. Ride for longer more comfortably and always be in control. The Shimano Altus makes climbing inclines more manageable than ever before.
Our Mars seven-speed city bike is also equipped with the RevoShift grip shifter. This shifting mechanism is integrated into the handlebars, so you can switch gears without ever sacrificing control of your ride. Changing speeds with RevoShift is intuitive, straightforward, and convenient.
The classic diamond frame on Mars seven-speed city bike is hand-built, tig-welded, and made of high-tensile strength steel. It’s designed for longevity, comfort, and reliability. The progressive geometry and handlebar location encourage an upright riding position, reducing the strain on your neck and back, especially as you ride longer distances.
Mars city bikes sport retro-inspired elements, like a chrome headlight, a mid-century bell, frame-matching fenders, and a polished rear rack. Cushiony grips and saddle make the ride more comfortable while front and rear brakes make the ride even safer. Kenda commuter tires grip the road even if it’s wet. Water dispersion grooves through the tread of these tires reduce slippage for an in-control ride.
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.
