Bulls Sonic EVO AM 1 Review

In the side view, the super delicate top tube and seat stay of the Sonic EVO AM 1 can only be seen as a thin line. This should appeal to design lovers in particular. Otherwise, the bike relies on the same values as all other Sonic models from Bulls. A four-link rear triangle with 130 mm of travel and the fork with 140 mm mm should level even medium-sized hits in the terrain.
Bosch is the major motor manufacturer in the EMTB world, alongside Shimano - and it's no surprise, as the Performance Line CX Smart System shows. With torque under the motor cover, the support is generous. Nobody needs to fear steep hills anymore. Furthermore, the power of the motor control is regulated so that the start always feels dynamic,. The average range can become a problem especially for long mountain bike rides.

At a glance

The most importanten ratings of the Sonic EVO AM 1 in comparison to the competitor bikes of following categorie: (5000) .

Carbon is considered a premium material in the bike industry. In the price range about 5000€, aluminium is usually the frame material used. With the carbon frame, Bulls can clearly differentiate itself from many competitors. On rough descents, the moderate chassis limits you and demands a more precise line choice than bikes with better chassis. At the brakes, Bulls instals upper class brakes with four pistons and 2 millimeter rotors from TRP. Shifting and components still leave room for improvement. Other providers dig deeper into their pockets for these assemblies. The handling of the bike is pleasantly balanced due to the moderate geometry. This allows you to intuitively control the bike over the trails. The bottom bracket is high, which costs handling points. This tends to make the rider stand on the bike. On other EMTBs it feels better integrated.

Conclusion


Expirience with the Bulls Sonic EVO AM 1

If you want to experience the much-vaunted uphill flow, the Sonic EVO AM 1 is a hot candidate for you. Overall, the Sonic EVO AM 1 due to an excellent motor and a good geometry is a good climber for tours on demanding single trails. But with a poor groupset and a moderate range there are also criticisms that come with the overall package.
