On the contrary, more aerodynamic  recumbent bike has a different type of frame with reclined position. Frame  materials have evolved over several years. From the simple steel, there are  celluloid, alloys made of aluminum and costly titanium and carbon fiber frames.  The next important thing you should know is the drive train of the pedals. This  is one of the most important bicycle parts because it is the speed on which  speed depends. Pedals rotate cranks held by the bottom bracket that helps in  transmitting power to rear wheel. Selecting the perfect gear for the biking  activity can affect the efficiency of biking.

Medium  sized gears are perfect for flat surface whereas a low gear is designed for  climbing uphill as it helps in reducing fatigue. A cycle also consists of  various kinds of handle bars. Among them, most common is the upright handlebar  which offers a comfortable position as well as a perfect grip while pedaling the  cycle. On the contrary, a drop handlebar offers more breaking power to the rider  during crouching position. Most of the mountain bicycles are well equipped with  straight handles for the purpose of handling the wheel in a better  manner.
