Overview of components
Fork material
The fork is made out of steel, so, it can add some extra weight to your bike. However, steel is a pretty tough and durable material.
Wheels
When it comes to wheels, the Boss COASTER STEP-OVER bike is equipped with the 26″ aluminum model. Being a little smaller, these wheels will fit both small and tall riders. However, they are less forgiving when riding over obstacles such as bumps and roots.
Brakes
When you want to stop the bike in time, the brakes are vital. The Boss COASTER STEP-OVER has Coaster brakes. Coaster brakes are among the oldest brake types you can find on a bike. However, if your chain falls off or snaps, your coaster brakes won’t function anymore.
