The "E-STREAM EVO 1 27.5 black" model from Bulls, released in 2024, is a high-quality e-mountain bike characterised by its robust and well-engineered design. The frame is made from 6061 aluminium and was manufactured using hydroforming. It is designed to accommodate a 1.8 steerer tube and features internal cable routing and a thru-axle.

Optimal braking performance is provided by the SHIMANO BR-MT420 hydraulic disc brakes, which are fitted with a SHIMANO SM-RT30 CL 180 mm brake disc at the front and a SHIMANO RT-EM300 CL 180 mm brake disc at the rear. Gear changes are handled by the SHIMANO Cues RD-U6000 system, controlled by the SHIMANO Cues SL-U6000 shifter. The rider has a total of 10 gears at their disposal.

The front fork is a BULLS Lytro 34 Air 1.8 Boost with 120 mm of travel, which ensures good damping and stability off-road. Lighting can be added as an option via the MonkeyLink Connect system, although the corresponding front and rear lights are not included.

The bike is fitted with BULLS MTB pedals, and the FSA crankset has a length of 165 mm. The SHIMANO CS LG300-10 cassette offers a gear range of 11–48T, whilst power is transmitted via the SHIMANO CN-LG500-10/11 chain.
