Two Gears, Zero Thinking — the 16" Bike That Shifts Itself
The woom GO 3 AUTOMAGIC is built for kids ages 4–6 who are ready to go faster and farther without getting spun out on a single-speed bike. The Sturmey-Archer Automatic A2 internally geared rear hub starts in an easier gear for relaxed pull-aways and hill starts, then automatically shifts to a higher gear at around 7 mph — no levers, no instructions, no fuss. The AA 6061 aluminum frame keeps the whole bike at 14.6 lbs, light enough that kids can handle, maneuver, and even carry it themselves.
Every detail is sized and spec'd for small riders. Ergonomic brake levers are shaped for short fingers, the rear brake lever is green so kids know exactly which hand to use, and a flexible rubber steering limiter prevents the front wheel from overturning and causing a crash. Forged 95mm aluminum cranks keep the pedaling stance narrow for a natural, comfortable stride, and the quick-release seatpost clamp lets parents adjust saddle height tool-free as kids grow from the 19" minimum to 25.1" maximum saddle height.
