Mounted battery and hub motor: The E-ST 900 27.5+ wants to distance itself from modern e-mountain bikes and prefers to go after customers with a favorable price.
At steep sections, the somewhat weak Brose motor requires a lot of initiative from the rider. The Brose Drive T Alu gives off a natural riding feeling. Fans of XXL tours are greatly restricted by the E-ST 900 27.5+ , because of its low range.

At a glance

The most importanten ratings of the 27.5+ Inch Electric Mountain Bike E-ST 900 in comparison to the competitor bikes of following categorie: (2000) .

The good Rock Shox fork dampens small and medium bumps confidently when mountain biking. Especially heavy riders should be aware that the Tektro only decelerates poorly. 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. On winding trails, the playful handling comes to the fore, as the bike masters even the fastest direction changes with the short wheelbase playfully. The small 27.5 inch wheels give the bike a lively character. The low bottom bracket height will likely be a sticking point for trail riders, as it negatively affects handling.

Conclusion


Expirience with the Rockrider 27.5+ Inch Electric Mountain Bike E-ST 900

With a good groupset the E-ST 900 27.5+ counts among the better climbers on the market. This emphasizes its fun factor on tours on forest paths and easy trails. Nevertheless, a weak range and a middle ground motor also give cause for criticism. We have to stay honest. Be careful when choosing the size: The Aluminium frame sizing runs small.
