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.
