With summer in full swing, there are few better ways to get the kids out and exercising than with a bicycle. The Trek Jet 20 single speed bike offers Trek toughness and quality, while letting you adjust far more than just the seat height. 

Built with fast-growing kids in mind, the Jet 20 offers the ability to "dial" in adjustments to the frame, brake lever, peddle crank length, peddle size, grip diameter, gearing, handle bar and stem (horizontally and vertically), and of course seat height. 

Features include a lightweight aluminum 20-inch frame, both hand and coaster (peddle) brakes for safety, and high-quality parts and construction that outperform cheap department store models -- such as alloy linear-pull brake, alloy rims, and Bontrager tires. It is available in matte black/"blue moon" and white/lime green, and retails for $246.99. 

It is available in the incentive market exclusively from Zane's Cycles, which offers its "True-Fit system in which the recipient provides a Zane's specialist information on the rider's measurements and the bike is built, custom-fit, and re-boxed before being delivered.
