The “COPPERHEAD EVO 2 ABS 29 black/berry Diamant” model from the “Bulls” brand, released in 2024, is a robust and technically advanced e-bike, available at a price of 3,999 EUR. The frame is made from 6061 aluminium, manufactured using the hydroforming process with internal cable routing, ensuring both stability and a clean, sleek appearance. The maximum permissible weight is 130 kg.
Safety and control are ensured by the TEKTRO Volans HD-T533 hydraulic disc brakes with ABS, fitted with TRP RC02E 203 mm Centre Lock brake discs at both the front and rear. Gear changes are handled by the SHIMANO Cues RD-U6000 11-speed rear derailleur and the SHIMANO Cues SL-U6000 shift levers, enabling precise and reliable gear changes.
The SR SUNTOUR XCR 32 Boost LOR Air CTS fork, with 120 mm of travel, provides comfortable suspension and damping on uneven terrain. The bike is compatible with the MonkeyLink Connect lighting system, although the front and rear lights are not included.
The spec includes BULLS MTB pedals, an FSA 165 mm crankset and a SHIMANO CS-LG400-11 cassette with a gear ratio of 11–50T. Power is transmitted via the SHIMANO CN-LG500-10/11 chain. The handlebars are the STYX Sport-SL model, complemented by comfortable sport grips and a BULLS MTB-SL stem, which is CCS Slot Mount ready. The headset is an FSA No.57SC.
The BULLS DDM-30 rims are fitted with VEE TIRE Crown Gem 66-622 tyres, mounted on FORMULA CL-811 hubs at the front and FORMULA DC-2241QR hubs at the rear. The BULLS Sportive Ergo saddle and the BULLS aluminium seatpost, with a diameter of 30.9 mm, offer additional comfort.
The e-bike is powered by the Bosch Performance Line CX (Smart System) motor with an output of 25/85 Nm, powered by a Bosch PowerTube 500 battery with a capacity of 500 Wh. The display is a Bosch Purion 200 model, and the charger has an output of 2 A. An ABUS battery lock is also integrated to ensure the battery’s security.
