A mountain bike or mountain bicycle (abbreviated MTB) 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
Road bikes, or racers as they are sometimes referred to, are speed machines – bicycles designed to take you as far and as fast as your legs can manage. The road bike gets its name from the terrain it is designed to be used on; yes, you guessed it, tarmac.
