Make the city your playground. The Co-op Cycles CTY 2.1 step-through bike has a shock-absorbing fork for pothole-filled roads and a 2 x 9 drivetrain for optimal options without complicating shifting.

  • Features

    • Low crossbar for easy mounts and dismounts
    • Upgraded 2x drivetrain (from previous model's 3x) makes for smoother shifting—and less of it too
    • Suspension fork provides 63 mm of travel to smooth out rough roads
    • Reflective sidewalls enhance visibility
    • Riser handlebar puts your hands in a natural position to reduce strain
    • Ergonomic grips provide comfort and support hands
    • Double chainrings simplify front shifting and provide plenty of gears for flats or hills
    • Tektro hydraulic disc brakes provide sure stopping power in variable weather
    • Top tube attachment points let you mount a bag where it's easy to access (like the REI Co-op Junction top tube bag, not included)
    • Accommodates a rear rack and fender (rack and fender not included)
    • Bicycle weight limit is 300 lbs. total, including rider + all gear carried on the bike and on the rider's body
    • Specs and images are subject to change

Included: derailleur and brake adjustments, lateral wheel truing, hub and headset bearing adjustments, tire inflation and chain lubrication. Not included: replacement or installation of new components or accessories, any other services. Call your local REI Co-op Bike Shop for more information.
