The SONIC EVA SX 1 is undoubtedly one of the slickest EMTB hardtails we've ever laid eyes on.
The SX from Bosch shows impressively that they shouldn't be limited to DIY and household products. 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. Fans of XXL tours are greatly restricted by the SONIC EVA SX 1 , because of its low range.

At a glance

The most importanten ratings of the Bulls SONIC EVA SX 1 in comparison to the competitor bikes of following categorie: (5000) .

Carbon frames are rather the exception in the price range of about 5€. With the carbon fibre chassis, Bulls thus sets clear accents compared to the aluminium competitors. Good damping qualities are shown through the Bulls mid-range fork. At the brakes, Bulls middle class four pistons brakes by Shimano are used. The components and the gears are less in the spotlight with an EMTB than with bikes without motor. Nevertheless, when we take a look we find out that here, good components are always used. The handling of the bike is pleasantly balanced due to the moderate geometry. This allows you to intuitively control the bike over the trails. Overall, the Bulls developers have done a great job with a god geometry. When I looked at the weight of the complete bike, my jaw actually dropped. With 17,9 kg, the SONIC EVA SX 1 is a real lightweight. Especially going downhill, the good geometry of the SONIC EVA SX 1 really shines.

Conclusion


Expirience with the Bulls SONIC EVA SX 1

The concept of Bulls really hits the mark with the SONIC EVA SX 1 for a very wide range of target groups. With an outstanding handling, a very good motor and a good groupset it is undoubtedly an outstanding all-rounder for tours on gravel roads and simple forest paths. Only an average fork and a middle ground brake system slightly tarnishes the overall impression.
