BULLS SIX50+ E FS 2 is built around current technology and powered with a Bosch mid-engine CX Performance Line 250W motor. The mid-engine design is ideal because of its lower center of gravity. The power is supplied by a 36V, 500 watt-hour battery that sits on the downtube.

The new frame design of tilting the Bosch motor 60% upwards has given the SIX50 series a more sporty and slicker look. Constructed around an aluminum frame this eBike features everything you want out of a full suspension all-mountain bike. Thru-axles are utilized to increase rigidity, a tapered headtube improves handling, and a Skid Plate to protect the motor from rocks and rough terrain. A special chain guide is used which not only prevents the chain from hitting the chainstays but is designed to reduce drivetrain influences to the suspension.

With suspension duties handled by RockShox suspension, and gearing from Shimano’s XT line you the SIX50+ E FS 2 is loaded with reliable components. This eBike has a charge time of 3.5 hours making it one of the fastest on the market. You can alternate the power output from 4 different modes, Eco, Tour, Sport, and Turbo.

The redesigned frame allows for more tire clearance allowing you to use plus size tires for additional traction and maximum traction. Wider tires also absorb more bumps on the road, essentially giving you a more comfortable ride.
