Bulls SONIC EVO AM SX-I Review

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 progressive. 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. The short range unfortunately limits the tour radius quite significantly.

Even nasty descents get smoothened by the good Rock Shox chassis. Bad brakes reduce the riding pleasure. Fortunately, this is not the case with the SONIC EVO AM SX-I. With their four pistons and large brake rotors the TRP brake brakes good. At the drivetrain components and the rest of the parts, Bulls uses good equipment. 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 low bottom bracket height is a party pooper for the handling on the trail. On other bikes, you are more centrally located behind the handlebar. For the good geometry, the developer team of Bulls definitely deserves props. Such a knack for detail in geometry is rarely seen. With its slim weight, the SONIC EVO AM SX-I is one of the lightest EMTBs. Especially going downhill, the good geometry of the SONIC EVO AM SX-I really shines.
