The BULLS COPPERHEAD EVO AM 4 750 is 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.
