Frog 47 Kids Bike
The First Pedal 47 is the third bike in Frog's new and improved frame range, that has been carefully designed to help maximise 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 inside leg of 47cm.
 
The Frog 47 offers a super lightweight frame, for ease of handling, weighing just 6.75kg. It is one of the lightest 18" kid's bikes on the market.
 
The bike offers a low bottom bracket position to ensure a safer riding position, whilst 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 lightweight bikes are a great confidence booster because of their ergonomic design, but if your child hasn’t mastered the art of pedalling just yet, the bike can also be used as a balance bike for a taller child by simply removing the pedals.

How to choose a Child's Bike

In contrast to many children's bikes, Frog bikes are sized by the length rather than age, as this is the most reliable way of getting the right size of bike for each child. Age alone isn't a reliable measure as there is a large spread of "normal" leg lengths & heights for age.

Please take the time to measure the rider's inside leg. It's easy to measure:

  1. Stand the child in socks against wall
  2. Place a small book between their legs, as high as is comfortable
  3. Ask the child to move away and measure from the top of the book to the floor

Once you have measured the inside leg, use this table to find the right size bike for your child. Note we give the MINIMUM inside leg length for each bike, with the saddle at it's lowest setting. At this height, the child will safely be able to get their feet to the ground. Don't worry - Frog Bikes have long seat posts, so the saddle can be raised a long way as the rider grows.

Of course all children have different length arms and torsos too, so to ensure a comfortable riding position, the handlebar height can be tailored, and saddles can be slid back and forwards on their rails.(These adjustments are easy to do and just need an allen key; instructions are in the manual that comes with each bike.
