The superlight, all-rounder 20" children's bike for riders aged six and up with disc brakes, 7 gears and all-terrain tires.

The gold standard in kids' geometry

Ergonomically designed for kids – the woom EXPLORE is built for max comfort with a slightly stretched-out riding position. The small kink in the top tube makes it easy to mount, and the clean frame design gives the perfect aesthetic.

Ultra-comfy saddle

Water-resistant, hard-wearing and sized specifically for the woom EXPLORE 4, 5 or 6, we made this saddle in collaboration with Selle Royal to ensure game-changing comfort for young riders.

Standout style

Every ride, every day—this bike’s style never quits. Its fresh, angular frame design is finished with black components and black rims. Incoming: confidence, exploration, independence.

Powerful disc brakes

Designed to bring young riders to a stop safely and comfortably in all conditions, using child-specific, reach-adjustable brake levers for peak braking performance.

Easy-to-use twist shifter

The woom EXPLORE 4 (20") features high-quality Shimano seven-speed gearing with an easy-to-use twist grip shifter that puts kids in charge of their ride. In short, intuitive independence at its best.

Ergonomic grips

Narrow, child-specific grips engineered with targeted comfort zones for the ultimate hand-to-bar contact for rides of any distance. Instead of achy wrists – think confident, capable and comfortable.

Our "Ride Happy" Guarantee: We want you to love your purchase, but if you are not completely satisfied, we offer hassle-free returns on all orders.

You have 30 days from receiving your order to initiate your return with us:

  • Returns must be in NEW condition with original packaging and product tags.
  • You are responsible for packaging and return shipping. You may purchase a return shipping label from us, which is likely your least expensive option with our discounted rates.
  • Please take your new bike for a "test ride" to make sure it's right for your Rider! Our standard for still being in new condition after a "test ride" is similar to a local bike shop that offers test rides outside their shop. We understand some "dust on the tires," but please keep it new (and hold on to packaging) until you are sure you're keeping it!
  • Your original shipping cost is non-refundable.

If you'd like to return your order, please start here.

Ready Set Pedal stands behind all products we sell. Most of our brands (including all bikes) offer a limited warranty. We will work directly with the manufacturer (on your behalf) to evaluate and process your warranty claim. If the issue/defect is deemed eligible to be covered under warranty, we work to get you a replacement, repair or refund as quickly as possible. If you're experiencing an issue/defect with an order, please contact us for support.
