The Frog 47 First Pedal Bike (18" Single Speed) has been carefully designed to help maximize the lifetime of the bike for a growing child. It is the ideal first pedal bike for 4 to 6-year-olds with an average inseam 18.5".

The Frog 47 offers a super lightweight frame, for ease of handling, weighing just 14.9 lbs. It is one of the lightest 18” kids’ bikes on the market. The bike offers a low bottom bracket position to ensure a safer riding position, while allowing for a greater leg-length range to be accommodated, perfect for growing children. There is also a 10mm spacer above the handlebar stem to give the option to raise the handlebars higher as your child grows. The Frog 47 is built using the same high-quality components as all other Frog bikes, including the patented narrow q-factor crank, to make riding for children more efficient and comfortable.

Frog's lightweight bikes are a great confidence booster because of their ergonomic design, but if your child hasn’t mastered the art of pedaling just yet, the bike can also be used as a balance bike for a taller child by simply removing the pedals.


  • Patented Frog Cranks: For easier 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.
  • Rear Freewheel Installed (No Coaster Backpedal Brake): All the benefits of handbrakes from the first day of riding. This bike is NOT available with a coaster brake.
  • 440mm Width Handlebar with 30mm Riser: To ensure a comfortable reach for your child.
  • Adjustable Handlebar Height: Handlebar height can be adjusted within a range of 40mm as your Rider grows.
  • Safety Steering Lock: Preventing oversteering that can cause an accident. Safer for learners, but still super nimble for more aggressive riders!
  • 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.
