Bulls SONIC EVO AM 1 29/27,5 Review

Front big, rear small. The wheel combo of the SONIC EVO AM 1 29/27,5 is currently trending. But does the concept also deliver riding joy, or is it merely about being hip?
The Performance Line CX Smart System from Bosch shows impressively that they shouldn't be limited to DIY and household products. No matter how steep or technical the climb is: the Bosch motor makes it conquerable! At the same time, the drive provides a very well-rounded feeling while riding with a dynamic power delivery. The well-tuned driving modes hit the mark. 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 29/27,5 in comparison to the competitor bikes of following categorie: (5000) .

Especially on root-strewn trails, the low-quality chassis puts the rider in front of greater challenges than necessary. Especially for heavy riders, the Bulls brakes could be a problem. With four pistons they only decelerate averagely. 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. Oh boy, with the geometry you have to be ready to make compromises from our perspective. The most important measurements and angles fall slightly out of the grid of good bikes.

Conclusion


Expirience with the Bulls SONIC EVO AM 1 29/27,5

The SONIC EVO AM 1 29/27,5 is a great climber. With an excellent motor, long tours in the even in alpine terrain are enjoyable. However, there is also a bitter pill to swallow with a weak groupset and an average range.
