Introducing the Frog 53 Hybrid Bike (20" 8-Speed), a versatile 20-inch hybrid bicycle designed specifically for children aged 5 to 7 years old. This top-of-the-line hybrid bike features a lightweight and durable aluminum frame, weighing only 18.0 lbs. Its maneuverability on various surfaces like roads, sidewalks, trails, and forest paths is unmatched. With Kenda Small Block Eight tires, the bike offers exceptional stability and grip. It comes complete with full-length mudguards and the option to attach a pannier rack, perfect for carrying school books and sports equipment.

The Frog 53 Kids' Bike is equipped with components tailored to your child's age. It has replaced the older Frog 52 and Frog 55 models. It includes a quick-release child-specific saddle for optimal riding comfort and FrogFit Technology® youth-specific 8-speed gear shifters. With their short lever travel and smooth cabling, changing gears and conquering hilly terrains becomes a breeze. The bike also features Tektro brakes with small, easily reachable brake levers, providing better control and boosting young riders' confidence. Additionally, our patented Frog cranks ensure effortless pedaling, reducing the distance between the pedals and enhancing efficiency and comfort for children.

Designed for longevity, the Frog 53 is optimized to grow with your child. Its lower bracket position guarantees a safer and more ergonomic riding experience, accommodating a wider range of leg lengths to suit growing kids. Furthermore, the handlebar height can be adjusted within a 40mm range as your child continues to grow, ensuring a perfect fit at all stages.


  • Lightweight 20-Inch Geared Bike: Built for easy handling.
  • FrogFit Technology 8-Speed Gears: Designed just for kids for easy gear change.
  • Patented Frog Cranks: For more effortless pedaling, with reduced distance between pedals to increase efficiency and comfort.
  • Lower Bottom Bracket: To help accommodate a greater leg-length ideal for growing kids.
  • Child Specific, Easy-to-Reach Tektro Hand Brakes: With adjustable levers, perfect for smaller hands. Better control means improved confidence for young riders.
  • 460mm Width Flat Handlebar: To ensure a comfortable reach for your child.
  • Kenda "Knobby" Off-Road Tires: A versatile tire that work great on dirt, grass, gravel, roads, or bike paths!
  • Easily Installed Mudguards: Useful if you ride regularly where the mud is flying.
  • High Quality Chain Guide Preinstalled: Includes an optional full chain guard to be installed if you prefer.
  • Child Sized, Soft Handlebar Grips: For comfortable riding.
  • 4 Reflectors: 1 front; 1 rear; 1 on each wheel.
  • Black Frog Bell: To let others know you're approaching.
  • "Touch-Up" Stickers: Matched to your bike's color, designed to cover those inevitable scratches that arise from everyday use.
  • Clear Frame Protective Stickers: For preventative protection as needed.

* MINIMUM INSEAM measurement for a child who is large enough to ride this bike. Beginner (or timid) riders must reach the ground comfortably and flat footed while straddling the seat, meaning their inseam must be close to the minimum seat height. Experienced (or confident) riders will be more comfortable raising their heels off the ground when straddling the seat. See Kids Bike Sizing Guide.
STANDOVER HEIGHT is measured from the top of the top tube to the ground, passing directly by the front of the chainring.


Getting your kid on the right size bike is important and easy! All you need is:

  • RIDER INSEAM =  Your child's inseam, measured from the top of the crotch directly to the ground. (This is NOT a pant leg inseam measurement).
  • RIDER EXPERIENCE = Your child's ability, comfort and confidence levels while riding a bike.

With these two pieces of information, you can easily calculate the MINIMUM SEAT HEIGHT your child needs on their new bike.

See our Kids Bike Sizing Guide for more details. And see Choosing the Best Bike for YOUR Child for our comprehensive guide to find your kid's next bike!

If you do have any further questions or concerns about sizing, please contact us and one of our Kids Bike Experts would be happy to help!

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.
