Take on steep slopes and tough trails with glee on the 27.5″ Men’s Excursion Mountain Bike from Mongoose. Made for experienced MTBers and new riders alike, this hardtail mountain bike is built with a durable steel mountain frame and front suspension fork that are designed to take the abuse of bumps and dips found on dirt paths and trails. 21-speed twist shifters and the Shimano rear derailleur offer complete control over resistance and speed while traveling, giving you a wide gear range and letting you fine-tune your ride as you go. The Excursion benefits from light and strong alloy rims that help lighten the load and knobby mountain tires that dig into dirt, sand or grass on your toughest rides. Slowing down to a halt, even on a steep hill, is simple thanks to the front and rear linear pull brakes. Add in the steel 3-piece crank for superior gearing and there’s only one choice for your next Excursion companion. There’s nothing you can’t do on a Mongoose.
