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 e-bike.
Wheels size
When it comes to wheels, the Thundra 29 e-bike is equipped with the 29″ aluminum model. With 29″ wheels, bumps will feel lighter and you’ll gain more speed on descends, compared to smaller wheel-sized bikes. However, 29″ wheels will make your e-bike react slower to obstacles you may encounter.
Brakes
When you want to stop the bike in time, the brakes are vital. The Thundra 29 has Hydraulic Disc brakes. Hydraulic disc brakes provide amazing stopping power, no matter what the terrain. To sum up, these are ideal for anyone.
