Overview of components
Fork material
The fork is made out of steel, which is tougher than carbon in the case of an impact. However, it can add some extra weight to the bike.
Wheels
The Cosmic 20 2020 bike is equipped with 20″ aluminum wheels when leaving the factory. The 20″ wheels are a good fit for folding bikes, BMX, or children bikes. In conclusion, you can use them better on-road, and less on technical terrain.
Brakes
We ride faster and faster, so a good braking system is essential on a bike nowadays. The Cosmic 20 comes with Rim brakes. Slightly lighter than hydraulic brakes, rim brakes are a budget choice. However, you could spend a little extra and get a bike that has hydraulic brakes.
