As the name suggests a Mini Bike is a miniature version of a motorbike. While some of these models use a two stroke engine, some versions use a four stroke engine. The two-stroker has a power stroke, and a subsequent exhaust pulse for each rotation of the crankshaft that creates a louder noise. Also, the two-stroker can produce more pollution in the air.
The cheapest Mini Bike is probably worth around 150 USD, and speeds up to 25mph.Though many bikers ignore wearing safety gear while riding this kind of a bike, one must understand that is not a toy, and should always wear a helmet while riding.

Crotch Rocket bikes, though every adrenalin junkie's dream machine, is a slang term for the mini-sized super fast machines that make the rider hunch up and vroom off. Leaning forward on the seat with their feet towards the back of this category of the sports bike, helps streamline the biker's position with the machine while driving at high speeds. Although the machines are lighter for easy handling and increased speed, they are often difficult to manoeuvre in winters with ice and slush on roads. With the engine completely covered by the body of the bike, these machines, unlike the cruiser bikes are made with one objective in mind: speed. While cruiser bikes allow for comfortable rides, there is more serious fallout of the crotch rocket bikes' insistence on speed: accidents.
