Overview of components

Fork

The RockShox 35 Gold RL is included from the factory. It has a travel distance of 150mm. Bike forks are great for shock absorption and provide you with a smooth ride. In conclusion, always look for a fork with decent travel when you buy a bike.

Rear Shock

Rear shocks give you increased comfort, control, and traction, which is important when cornering or braking. This allows you to ride faster on bumpy roads. In short, if you want smooth rides, get a full-suspension bicycle.

Wheels

The THEOS F50 29″/27.5″ 720Wh 2021 e-bike is equipped with 29″ aluminum wheels when leaving the factory. These wheels are more forgiving when you go over roots, rocks, bumps, or other obstacles you encounter on your ride. However, the 29″ wheels will add a little more weight to the e-bike itself.

Brakes

When you want to stop the bike in time, the brakes are vital. The THEOS F50 29″/27.5″ 720Wh has Hydraulic Disc brakes. Hydraulic disc brakes provide amazing stopping power, no matter what the terrain. To sum up, these are ideal for anyone.
