The ultra-flat top tube and the skilled line work give the SONIC EVO AM SX 2 a futuristic aesthetic. The integrated lights complement it perfectly. But it's the bike's riding characteristics that really shine on the trail.
Bosch is the major motor manufacturer in the EMTB world, alongside Shimano - and it's no surprise, as the SX shows. The Swabians from Bosch are sending their first light engine into the race with the SX. With 55 Nm torque, this unit places exactly in the middle between Fazua's Ride 6 and TQ's HPR 5. However, it delivers up to 6 watts of support, similar performance figures to the popular Bosch CX. The starting behavior remains dynamic. The complete motor control is very $natural. In terms of installation space and sound, the small Bosch can't quite keep up with its competitors from the Light segment. Fans of XXL tours are greatly restricted by the SONIC EVO AM SX 2 , because of its low range.

At a glance

The most importanten ratings of the SONIC EVO AM SX 2 in comparison to the competitor bikes of following categorie: (7000) .

Carbon is considered a premium material in the bike industry. In the price range about 75€, aluminium is usually the frame material used. With the carbon frame, Bulls can clearly differentiate itself from many competitors. Solid endurance qualities are shown by the chassis of medium quality. Bad brakes reduce the riding pleasure. Fortunately, this is not the case with the SONIC EVO AM SX 2. With their four pistons and large brake rotors the TRP brake brakes good. Taking a holistic approach also includes looking at the gearing and components. The components are of good qualtiy and offer no reason for criticism here. When it comes to the geometry, Bulls does not go completely crazy. The head tube angle and reach values were chosen with care. The result: A balanced riding behaviour with a good combination of playfulness and straight-line stability. The low bottom bracket height will likely be a sticking point for trail riders, as it negatively affects handling. Short chainstays and and a slack seat angle make the front end light in steep climbs. To keep the front wheel on the ground, you need to consciously lean forward. Overall, the Bulls developers have done a great job with a god geometry. On the scale, the SONIC EVO AM SX 2 makes a good figure with 18,9 kg. Most Trailbikes are significantly heavier.

Conclusion


Expirience with the Bulls SONIC EVO AM SX 2

Overall, the SONIC EVO AM SX 2 is, due to an outstanding handling, a very good motor and a good brake system is a good all-rounder for trips on challenging single trails. Only an average chassis slightly tarnish the otherwise successful overall picture.
