The "COPPERHEAD EVO AM 1 29/27.5 nano grey" model from the "Bulls" brand, released in 2024, is a versatile and technically advanced e-mountain bike designed for challenging rides. The frame is made from high-quality 6061 aluminium, which has been shaped using a hydroforming process. This not only ensures high stability but also gives the bike an aesthetically pleasing appearance. The internal cable routing and provision for a telescopic seatpost contribute to a clean and modern design. The bike’s maximum load capacity is 130 kg.
Reliable braking power is provided by the SHIMANO BR-MT200 hydraulic disc brakes, fitted with a 180 mm front brake disc (SHIMANO SM-RT30 CL) and a 180 mm rear brake disc (SHIMANO RT-EM300 CL). Gear changes are handled by the SHIMANO Cues RD-U6000 system, which, in combination with the SHIMANO Cues SL-U6000 shifter, offers a total of 10 gears.
The bike’s suspension comprises a BULLS Lytro 34 Air Boost fork with 140 mm of travel and a rear shock with 150 mm of travel, ensuring excellent damping and control on rough terrain. A MonkeyLink front light and a MonkeyLink Mini rear light are integrated for added safety and visibility.
Other features include BULLS MTB pedals, an FSA 165 mm crankset and a SHIMANO CS-LG300-10 cassette with a 11-48T range. The drivetrain is powered by the SHIMANO CN-LG500-10/11 chain. The handlebars are BULLS Sport-SL riser bars, the grips are MTB Sport grips and the stem is a BULLS MTB-SL, 3D-forged and CCS Slot Mount-ready.
The rims are BULLS DDM-30 models, fitted with VEE TIRE Crown Gem tyres in sizes 66-622 at the front and 66-584 at the rear. The hubs are SHIMANO HB-TC500-B at the front and SHIMANO FH-TC500-HM-B at the rear.
