Copperhead EVO 2026

The Copperhead EVO is Bulls' aluminium trail hardtail eMTB, built around a monocoque diamond frame with the full-power Bosch Performance Line CX Gen5 motor (rated 100 Nm) and a 600 Wh Bosch PowerTube battery. It runs 27.5in wheels at both ends and carries Bulls' integrated MonkeyLink cornering light and Twinlight rear light hard-wired into the system. With no rear shock and a 120-130 mm fork, this is a do-it-all hardtail rather than a full-suspension trail bike.

Two builds are offered for 2026, both sharing the motor, battery and frame. The EVO 1 (EUR 3,599) pairs a 120 mm Lytro 36 fork with an 11-speed Shimano Cues drivetrain and basic BR-MT200 brakes on 180 mm rotors. For EUR 400 more the EVO 2 (EUR 3,999) is the stronger pick: a 130 mm RockShox Psylo Gold RC fork, 12-speed Shimano Deore shifting with a wider 10-51T cassette, and uprated BR-MT420 brakes with a 203 mm front rotor.

Geometry is moderate for a hardtail, with a 66.5 degree head angle across all sizes and a 73.5 degree seat angle (74 on XS). Reach runs from 425 mm on the smaller sizes to 479 mm on XXL, with chainstays of 430 mm on XS and S growing to 450 mm on M and up. Six frame sizes (XS to XXL) give an unusually wide fit range. Bulls classifies it for forest and field paths and advises against jumps over 60 cm, so it is pitched at trail and cross-country riding rather than aggressive descending.
