We're super proud of the Citizen's sleek frame design. With an arcing top tube for the "Men's" frames and S-bend top and down tubes for a super-low step-through "Women's" version. In fact, we hesitate to designate either with gender specific labels because the version with the easy-access, low step-over top tube is suitable for anyone with limited hip flexibility who might be challenged to swing a leg over the rear wheel when mounting & dismounting.

A usual complaint from new or returning riders trying to get into the cycling groove is feeling uncomfortably perched forward with too much weight on their wrists and having to crank their necks backwards just to be able to see in traffic. We specifically designed our Citizens to remedy this. The large diameter 700c wheels push handlebar height up and shorter top tubes pull handlebars closer to the saddle, all to mitigate forward lean. Our 4-inch rise handlebars sweep back at a natural hand-grasp angle with a long-quilled or angle-adjustable stem that allows for a wide range of adjustment to tune handle bar height and reach perfectly for each ride.

The shifting systems on all our Citizens feature long cage rear derailleurs, full-size 48/38/28T triple-chainring cranksets (single 44t chainring for Citizen base model) and big 11-32T or 14-34T gearing in the back. This gives you the dual advantage of having fairly tall gears for controlled pedaling at speed on descents as well as really low gearing for easier pedaling uphill. It's a rider-friendly combination that's made the Citizens a perennial favorite of recreational cyclists.
