The HardNine 7 comes factory-installed with the RockShox 35 Silver fork. This has a travel range of 120mm. Bike forks are good shock absorbers and provide a smooth ride and a great experience. In short, you should always ensure you have a good fork when purchasing a bike.
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
When it comes to wheels, the HardNine 7 e-bike is equipped with the 29″ aluminum model. 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.

We ride faster and faster, so a good braking system is essential on a bike nowadays. The HardNine 7 comes with Hydraulic Disc brakes. With Hydraulic Disc brakes, you’ll be able to stop on a dime, even in wet or icy conditions. To sum up, your safety is in good hands.
