Light, responsive, capable and practical—but never boring—the Cannondale Treadwell 2 bike bounds through the city and blasts through the boroughs with a stylish nod to funky bikes of the past.


  • Get that feeling of freedom that only two wheels can give: this simple and playful bike is perfect for rolling around, meeting up with friends and getting around town
  • Thanks to a lightweight aluminum frame and thoughtfully selected components, this fun machine isn't just easy to ride, it's also easy to lift and carry
  • Easy-Ride Geometry puts the handlebar in easy reach, makes it easy to put a foot down when stopped and features a low-standover frame that's easy to get on and off
  • An integrated wheel sensor helps track your activity—like speed, distance and calories burned—registers your bike and reminds you of needed service via the free Cannondale app
  • A convenient mount on the stem securely holds any SP Connect–compatible smartphone case, creating a dashboard display for speed, mileage and more with the Cannondale app
  • A quilted saddle and ribbed grips keep things comfortable while the pedals use deck tape instead of teeth for easygoing grip in anything from flip-flops to cowboy boots
  • Inspired by BMX and dirt-track racers, the Cruise Control handlebar puts you in just the right position for control while cruising—neither too upright nor too forward
  • Urban Armor bumpers help protect the frame from dents and dings during daily leaning and locking
  • Straightshot hidden cable routing and flat-mount disc brakes maintain a clean, functional look
  • Rack and fender mounts let you add functional accessories (not included) to your daily to-and-from
  • Specs and images are subject to change
