Let’s discuss the differences between these two vehicles first. The big difference is the engine. Bicycles don’t have one; you’re the so-called engine and we, as humans, cannot put out the horsepower of gas or electric powered engine or motor. Other differences are the weight, speeds attainable, cost, and proper operation. In both categories, most of the vehicles are equipped with gears for speed changes, and most MCs have 4-6 gears, whereas bicycles can have 1-21+. How do you stay upright on either? Well, to ride a motorcycle you must know how to ride a bicycle. The common denominator is power to the rear wheel, whether it’s the engine or your legs. Another difference is that bicyclists tend to disregard common traffic laws, which do apply to them as well such as disregarding of red lights, riding against oncoming traffic, and more others. Motorcyclists also disregard traffic laws, such as speeding, lane splitting, and DUI to name a few.
