woom ORIGINAL 3 AUTOMAGIC Kids' Bike
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.
Key Details
- 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

Awesome bike!
My son went from a balance bike to this and was able to pick it up in about 10 minutes. It was amazing to witness! Everything about the bike makes sense for a small child and he is even able to pick it up which gives him an independence and ownership of the bike. He LOVES it! Highly recommend, worth the price and seems well made to last as a hand-me-down.
