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
