A mountain bike is a bicycle designed for off-road cycling. Mountain bikes share similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain. These typically include a front or full suspension, large knobby tires, more durable wheels, more powerful brakes, straight handlebars, and lower gear ratios for climbing steep grades.<br> <br> Weight::About 31 lbs <br> Frame： Hiland Aluminum,front/rear wheel quick release <br> Fork：GOOD Suspension Fork travel 100mm<br> Crank：Prowheel 24*34*42T<br> Shifters：SHIMANO EF500 24Speeds <br> Front Derailleur：Shimano TZ500 Tourney<br> Rear Derailleur：Shimano TY300 Tourney<br> Cassette：Shimano 14-28T <br> Tires：CST 1820 26*1.95 <br> Brake type: Disc-Brakes
