Safety
When you go for a ride, don’t forget to put your helmet on. Moreover, ride with traffic, not against it. This will help you stay visible to drivers and also makes it easier for them to see you.
Trail bikes average price
If you want an acceptable Trail bike you should know that the average price is 2762$. However, even though the average price of a Trail bike is lower, you might still be able to get a top-quality bike. As a general rule of thumb, you should always read reviews about the bike and its components before buying it to ensure you don’t pay too much.
Furthermore, if we have a quick look at this model’s cost, we can see that at its release date the price was 4699$. Doing a quick comparison, we notice that PORTAL C3 price is 70.13% higher than the average cost of a Trail bike.
Average weight for Trail bikes
If we make a quick analysis of the average weight of a Trail bike, we get 12.98 kg (28.62 lbs). An easier bike will give you a big advantage in climbs. However, a heavier bike can gain speed when you descend.
Weighing 13.49 kg (29.74 lbs), the PORTAL C3 model is slightly heavier than average. To sum up, it’s 3.93% heavier than the average weight of Trail bikes.
Internal Cable Routing

PORTAL C3 components
Fork
This bike has the Fox Rhythm Float 34 fork installed. The fork’s travel is 130mm. Bike forks absorb the shocks and give you a smooth and pleasant ride. In conclusion, always look for a fork with decent travel when you buy a bike.
Fork material
When it comes to the fork, this bike has an aluminum one, 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
Rear shocks improve riding comfort and give you greater control over all terrains. To sum up, always consider getting a bike that has a rear shock as well.
Wheels
When it comes to wheels, the PORTAL C3 bike is equipped with the 29″ aluminum model. Having 29″ wheels means that you need less fork travel, leading to a reduction of the pedal bob effect. However, 29″ wheels will make your bike react slower to obstacles you may encounter.
Brakes
When you want to stop the bike in time, the brakes are vital. The PORTAL C3 has 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, these are ideal for anyone.
Sizes
There are 4 sizes available for this model. Rider height can be anywhere between 158 cm – 199 cm (5.18 ft – 6.53 ft). In short, it won’t be difficult to find the right one for you.
Dropper post
