E-Stream Evo AM 4 27,5+

Build spec

When looking at the build spec, it becomes clear that Bulls has put more emphasis on good value for money than high-end performance when choosing the components. The suspension consists of a 150 mm FOX 36 Rhythm fork, and a FOX Float DPS shock providing the same amount of travel at the rear. Shifting is taken care of by a Shimano XT drivetrain, while the powerful Magura MT5 brakes are responsible for deceleration – all in all, solid components with nothing much to criticise.

The highlight of the BULLS E-STREAM EVO AM 4

The highlight of the BULLS E-STREAM EVO AM 4 is undoubtedly the motor. At the heart of the aluminium frame is the new Brose Drive S Mag, which with its natural power delivery and massive power output, is the current benchmark for eMTB motors. The motor is fed by an equally impressive and neatly integrated 750 Wh battery, which can be easily removed if necessary.

The BULLS E-STREAM EVO AM 4 27,5+ in detail

Using Bull’s Monkey Link system, the E-STREAM EVO is compatible with lights, reflectors and mudguards, allowing you to connect the lights to the bike battery. Optionally, the E-STREAM EVO AM 4 can be ordered with the Connect C GPS module, which offers a wealth of features such as navigation, tracking your ride data or adjusting the support levels.

Remaining componentry

The remaining componentry is somewhat rudimentary and the same applies to many of the frame’s details such as the cable routing. The narrow cockpit looks crowded and the awkward combination of brake levers, shifters and motor remote are limited in their ergonomic adjustability. The lower-end componentry and the large battery are also noticeable on the scale: the Bulls weighs in at just under 23,7 kg.
