Stevens E-Inception AM 8.8.1 GTF
The Stevens is lightweight for a Bosch bike, featuring robust components and a removable battery. The new motor and updated geometry promise high performance. Powerful and safe even on rough terrain, the bike certainly lives up to this claim; however, Stevens can no longer capitalise on its value-for-money advantage to the same extent as before. There is still room for improvement in terms of noise levels, the suspension and the riding experience on moderate trails.
