Woom GO 4

A 20-inch first geared bike for kids ready to handle multiple ratios on hills and longer rides, the Woom GO 4 is the seven-speed kids' bike built for ages 6 to 8 with a saddle range of 22.4 to 28.7 inches. The aluminum frame keeps the complete bike to 17.2 lbs, light enough that a six-year-old can keep up on family rides without an oversized adult-derived bike fighting their cadence. A microSHIFT twist grip shifter pairs with a 28-tooth chainring up front and an 11 to 28 tooth cassette in back, giving a gain ratio range of 2.3 to 5.9 that covers flat spinning and shorter climbs without overwhelming a first-time geared rider. Dual V-brakes handle stopping, and a child-friendly indicator window on the shifter shows the current gear at a glance. BMX-style bars and a kickstand round out the build. Available in Hot Pink, Metallic Blue, Metallic Turquoise, Powder Pink, Vibrant Yellow, and Woom Red, the GO 4 is the geared step up from the single-speed GO 3 and the entry point into Woom's seven-speed drivetrain layout before the 24-inch EXPLORE 5 adds disc brakes and a trigger shifter.
