Equipped with automatic 2-speed shifting, the woom ORIGINAL 3 AUTOMAGIC Kids' bike allows young riders to go a bit faster and crank a little harder on flats and downhill without complex gear changes.
- Frame is geometrically designed for kids ages 4 and up and forged from sturdy, lightweight aluminum; its low entry point enables young riders to easily hop on
- 2-speed internally geared Sturmey Archer hub automatically switches gears from low to high at about 7 mph without any manual shifting necessary
- Optimized gear ratio provides less resistance in the low gear for an easier time getting started from a stop, then increased resistance as they speed up to supply more oomph
- High-rise handlebars promote a stable, upright riding position, which allows for easier balancing due to more control and comfort
- Specially developed steering limiter prevents the handlebars from overturning and helps children ride straight, which reduces the risk of accidents
- Stem offers a secure and lightweight connection between the high-rise handlebars and the rest of the bike
- Lack of protruding bolts and sharp angles on the stem and handlebars provides a smooth riding experience
- Color-coordinated brakes help kids identify which lever engages which brake; the innovative braking system helps them learn how to operate hand brakes early
- Use the reach adjustment knob to fit the brake lever to your little one's hands
- Ergonomic contact points are made specifically for kids to provide a more comfortable ride
- Saddle is designed to accommodate their anatomy and biomechanics; grips are ergonomically designed for kids' hands
- Quick-release seatpost clamp offers a simple, tool-free way to adjust the saddle height—it's easy enough to be operated by children
- Crank length and distance between pedals are ergonomically adapted to fit kids' bodies, resulting in an optimal stance and natural movements to make pedaling a piece of cake
- Pedals are durable, reflective and slip-resistant
- woom-designed chain guard helps keep riders' hands safe from pinches and snags; it's durable and frictionless but also easy to remove to lube the chain or change a flat tire
- SOOPA DOOPA HOOPS tailor-made wheels are designed for kid-specific geometry on woom 3 bikes
- Wheels feature smooth, frictionless hubs and double-walled 16 in. rims; rims come with a 16 stainless-steel spoke design to balance strength and light weight
- High-quality rubber tires provide plenty of traction and durability and make rolling a breeze; reflective striping on the sidewall helps ensure riders will be noticed

How we measure bikes
- Standover Height Standover Height is a measurement from the ground to the top of the top tube, measured at the midpoint of the top tube.
- Reach Reach is the horizontal distance from the center of the cranks to the center of the head tube, measured at head tube level.
- Stack Stack is the vertical distance from the center of the cranks to the center of the head tube, measured to the top of the head tube.
- Effective Top Tube Effective top tube is the distance from the center of the head tube to the center of the seat tube/seat post, measured parallel to the ground.
- Seat Tube Center to Top Seat Tube length is the measurement of the seat tube, from the center of the cranks to the top of the seat tube.
- Head Tube Length Head Tube Length is measured from the bottom to the top of the head tube.
- Head Tube Angle Head Tube Angle is the acute angle between the head tube and the ground (measured towards the rear of the bike)
- Seat Tube Angle Seat Tube Angle is the acute angle between the seat tube and the ground (measured towards the rear of the bike).
- Bottom Bracket Height Bottom Bracket Height is a measurement taken vertically from the ground up to the center of the cranks.
- Wheelbase Wheelbase is the measurement from the center of the front axle to the center of the rear axle.
- Chainstay Length Chainstay Length is the measurement from the center of the cranks to the center of the rear axle.
- Fork Offset Fork Offset, or rake, is the distance from the front axle to a line drawn parallel to the center of the head tube or steering axis.
