Pusher bikes are the smallest BMX bike. You can ride them on both dirt and streets; however, they do not have so much power and stability due to their size. 

Pusher bikes usually include a 20-inch wheel in front and at the back. This means that it doesn’t have sufficient pedal clearance for more oversized pedals like clipless models.

Freestyle Bikes

These BMX bikes are also smaller than the traditional street bike, with a medium frame size of 19-22 inches. The weight distribution on this bike helps you maneuver it better than other styles. This is because you do not need your center of gravity to be so high. 

Freestyle bikes usually have a 20-inch wheel in front and 20 inches or more clearance for larger pedals on the back frame. This makes them ideal for riders willing to ride clipless models.

Street Bikes

However, they are still designed to be used on both streets and dirt. Street BMX bikes also include a 24-inch wheel. This provides a better balance between street riding traction and dirt agility.

These BMX bikes include a 24-inch front wheel that provides more stability and a 24-inch back wheel that helps to balance agility and traction. This makes touring bikes more suitable, especially for riders planning several long-distance rides.

BMX bikes are available in 16″ 18″ 20″ 22” and 24″ inch wheels, but the most popular bikes are those with 20 inches wheels, which account for around 97% of sales. This means that anyone using the term BMX is most likely referring to a 20-inch wheel.

Generally, 20-inch wheel BMX bikes are used by children and adults of all sizes. However, the minimum age for this BMX bike is between seven and eight years. While adults are allowed to ride this 20-inch BMX bike, they should ensure that they wear the appropriate safety gear that keeps them safe.
