Built to get out of the rat race and into the wilderness, the Cannondale Tesoro Neo X 2 electric bike's MTB-inspired frame and fork along with big 29 in. wheels live to be pointed off pavement.


  • Secure, rattle-free fenders, a full rear rack, bright front and rear lights and even a kickstand mean you're ready to tackle any adventure
  • Performance Line Speed motor and powerful 500 Wh PowerTube battery are ready to tackle any terrain with support up to 28 mph and increased torque of 85 Nm
  • For double the range and double the adventure, frame comes prewired and ready for the installation of a second battery kit (not included)
  • Premium SmartForm C1 alloy construction creates an incredibly light, stiff and durable frame that's dual-battery-ready for extended adventures
  • Highly reflective accents on the frame and fork increase visibility in low-light conditions
  • Ai Offset Drivetrain opens up the rear triangle for more tire clearance, while keeping the chainstays short for nimble agility—a stiffer, stronger rear wheel is just icing
  • 100 mm of front suspension and wide 2.25 in. tires smooth out rough roads, gravel and potholes for a comfortable, confident experience on- and off-road
  • 11-speed Shimano Deore shifters and derailleurs provide crisp, accurate access to a range of gears; Shimano hydraulic disc brakes deliver excellent stopping power
  • Specs and images are subject to change
