Safety
Take safety seriously when you ride your bike, and always wear your helmet. Moreover, don’t ride on the sidewalk. This is actually against the law in some states and can be dangerous for both you and pedestrians.
Downhill bikes average price
If you want to purchase a solid Downhill bike, it is important to know that the average cost is 3391$. However, paying less money than this amount doesn’t mean that you couldn’t get a great Downhill bike. As a general rule of thumb, you should always read reviews about the bike and its components before buying it to ensure you don’t pay too much.
Overview of components
Fork
The RockShox BoXXer is included from the factory. It has a travel distance of 200mm. Bike forks are great for shock absorption and provide you with a smooth ride. In short, you should always ensure you have a good fork when purchasing a bike.
Fork material
Demo 8 I has an aluminum fork, which doesn’t add too much extra weight to the bike. However, it is not so stiff as steel or carbon forks are.
Rear Shock
From the factory, it comes with the Custom FOX VAN RC rear shock model, which has a travel of 200mm. Rear shocks improve riding comfort and give you greater control over all terrains. In short, if you want smooth rides, get a full-suspension bicycle.
Wheels
When it comes to wheels, the Demo 8 I bike is equipped with the 26″ aluminum model. Being a little smaller, these wheels will fit both small and tall riders. However, you will need increased suspension than in the case of 29″ wheels.
Brakes
For your safety, it is important to have quality breaks on your bike. Specialized Demo 8 I has Hydraulic Disc brakes installed. These kinds of brakes are among the most popular models used on bikes. To sum up, you can ride your bike with confidence.
Sizes
Demo 8 I comes in 4 sizes, that range from 151 cm – 184 cm (4.95 ft – 6.04 ft). In short, you can easily find one that suits you.
