Test / E-MTB: With the Cube Stereo Hybrid One55 TM we tested the popular “TrailMotion” version of the new E-MTB all-rounder from Cube. This relies on a completely new carbon frame and is significantly lighter and sportier than the old Stereo Hybrid 160.
It probably isn't a bold thesis that Cube's Stereo Hybrid models have been among the most popular and best-selling E-MTBs in this country in recent years. As a new model alongside the well-known bikes with 120, 140 and 160 mm travel, the One55 has big shoes to fill. With its 160 mm or 150 mm travel and 29-inch wheels, the new addition is positioned in the orbit of the somewhat outdated Stereo Hybrid 160 - somewhere between Trail, All Mountain and Enduro.
During development, particular emphasis was placed on low frame weight; For the first time on an E-MTB from Cube, the rear triangle is now also made of carbon. The frame weight drops to a remarkable 2,9 kg and so the top model SLT should only weigh around 750 kg despite the Bosch CX and removable 22 Wh battery. A consequence of the lighter full carbon frame is also a significant price increase compared to the well-known stereo hybrid models.
In the tested TM version, the One55 costs just under 8.000 euros - but also comes with elegant and robust equipment that is appropriate for the name. This ranges from the Fox Factory chassis to the complete Shimano XT equipment and wheels from Newmen. The 38 at the front fits a Trailmotion model just as well as the Maxxis tires. The soft MaxxGrip compound is used at the front and rear, and the puncture-proof DoubleDown carcass on the rear wheel - great! If we had to find a fly in the ointment, it would be the dropper post with “only” 175 mm of adjustment. Actually, that's more than enough, but due to the very short seat tube of 420 mm in size L, a 200 mm post would have been more suitable.

Cube has hit the jackpot with the geometry of the Stereo Hybrid One55: extremely comfortable when sitting, it places the rider centrally in the bike, which also helps on steep uphills. The modern, but not too extreme dimensions are a lot of fun on the trail. The relatively low rigidity of the frame and rear triangle is particularly noticeable when cornering. Although we were initially skeptical, the flex did not prove to be a problem in practice on natural trails and helped ensure that the Cube provided a lot of calm even on stony and rooty sections. However, if you spend a lot of time on built-up routes with residents, you might be bothered by the sometimes somewhat spongy handling.
As usual, there is little to complain about with the proven Bosch drive system; The motor cannot earn top marks only in terms of noise, although the noise level on our test bike was comparatively pleasant compared to other Bosch CX E-MTBs. However, a quiet clattering could also be heard on the trail.
