2025 BULLS

COPPERHEAD EVO 27.5

Bosh Performance Line CX motor is one of the best-performing motors found on eMTBs

750Wh Bosch PowerTube battery yielded more than 30 mi. of range in Turbo mode

Mullet wheel setup (29 front and 27.5 rear) made it easy to get the front wheel over rocks and obstacles while keeping the eMTB nimble in turns

12-speed Shimano Deore drivetrain gives riders a 510 percent gear range to cover any rideable terrain

4-piston Shimano hydraulic disc brakes with 203mm rotors gave excellent brake response

150mm travel frame is made from 6061 aluminum and comes in four sizes for a broad range of fit

We liked the Limotec A1-Z dropper post but would have preferred to have more than 125mm of travel

The quick-release thru-axle is nice enough but it is more complicated than traditional thru-axles, and more complicated might not be necessary

An all-mountain ebike with 150mm air suspension from SR Suntour, available in four frame sizes, unique mullet wheel setup. That means it has a 29" wheel in the front to help overcome obstacles and 27.5" wheel in the back for strength and quickness. High capacity Bosch PowerTube 750 with Smart System Performance Line CX motor, LED remote, and excellent smartphone app.

Plus sized 2.6" wide tires balance precision with float and stability. You get increased traction, reduced deflection, and improved comfort that aligns perfectly with the taller 29" front wheel. Wider Boost hub spacing and 15mm and 12mm thru-axles improve stiffness and wheel strength.

Unique dropper seat post from Limotech incorporates a bit of suspension for added comfort. Hydraulic disc brakes with large 203mm rotors provide good stopping power and cooling. Wide 11-46 tooth 10-speed cassette provides good climbing ability and comfortable high-speed cadence. Narrow-wide chainring and plastic guide reduce drops.

The bike is fairly heavy at 60.9lbs due to the high capacity 9.4lb battery pack, long travel suspension, and plus sized tires. No charging on the Bosch LED remote button pad despite having a USB-C port for diagnostics. Excellent position for charge port high on left side of the frame.
