Ride Position - A usual complaint from new 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 design our Explorers to remedy this. With extra long head tubes to push handlebar height up, shorter top tubes to pull handlebars closer to the saddle, 4-inch rise handlebars that sweep back at a natural hand-grasp angle and long-quilled or angle-adjustable stems that allow for a wide range of adjustment to tune handle bar height and reach perfectly for each rider.

Comfort Saddle - Our super plush saddle features memory foam padding (Explorer Sport) or extra high quality polyurethane padding (Explorer) for optimum support with maximum comfort. The slip-resistant suede-type top prevents sliding and the burnished side panels reduce leg friction while pedaling. Elastomer springs also help to soak up road vibrations. Offered in gender specific sizes.

Pump Up The Volume - Our Explorer tires are ready for anything; they roll smoothly on pavement but offer a large 2.1” footprint and side knobs so that traction off the beaten path is never an issue. The additional benefit of that big footprint is larger air volume in the tire and tube, which results in lower air pressure for a more comfortable ride than tires with smaller volumes and higher air pressures.

Versatility - But don’t let all this comfort talk fool you into thinking the Explorer has limited uses. While conceived to make cycling as comfortably fun as possible, the Explorer is capable of doing much more than keeping a new rider from hurting. Thanks to the full-range gearing of the drivetrain, the 2.1” footprint of the tires and the shock absorption of the suspension fork.
