  • Our take on the Darwin IV 24-Inch Kids Bike

    The Darwin IV is a 24-inch kids bike built on a ROCKBROS aluminum frame with a Shimano CUES 9-speed drivetrain. It comes in two versions: a rigid aluminum fork or a magnesium-aluminum suspension fork with spring adjustment and lockout. The 9-speed gearing is more range than most 24-inch kids bikes, which usually run 6 or 7 speeds, so it suits riders ready for hills and longer rides. The suspension version adds comfort on rough paths at the cost of weight and one more part to maintain.

    Questions and answers

    Is the Darwin IV good for a first 24-inch bike?
    Yes, if the child is comfortable with hand brakes and gears. The 9-speed Shimano CUES drivetrain takes some learning, but the aluminum frame keeps it manageable. A single-speed or 7-speed bike is simpler for a complete beginner.
    Rigid or suspension fork: which should I pick?
    Choose the rigid fork for pavement, bike paths and lower weight. Choose the suspension fork with lockout if your child rides gravel, roots or rough trails, and lock it out for climbs and smooth surfaces.
    What does the 9-speed Shimano CUES drivetrain give my child?
    A wider gear range than the 6- or 7-speed setups common on 24-inch kids bikes. That helps on hills and longer rides. Shifting is via a trigger shifter, so the rider needs enough hand strength for it.
    How does it compare with other 24-inch kids bikes?
    Its aluminum frame and 9-speed Shimano CUES gearing are a step above the steel frames and basic 6-7 speed drivetrains on many 24-inch bikes. The suspension option adds trail comfort that rigid rivals lack.
    What is included with the bike?
    The bike ships with the ROCKBROS aluminum frame, the chosen fork, and the Shimano CUES shifter and rear derailleur. Brakes, wheels and other parts are not detailed, so confirm the full spec before ordering.
    Where is the Darwin IV 24-Inch Kids Bike cheapest?
    At ROCKBROS-US, for $419.99, as of our latest check.
