The First Pedal Frog 40 is a great value bike for 3 to 4 year olds with an average inside leg of 40cm.

One of the biggest temptations is to buy a bike your child will 'grow into'. However, this is likely to have the opposite effect as the they'll struggle with a bike that's too large for them and it could put your child off bikes and cycling altogether! Another common mistake is to purchase a budget bike for them to learn on but these models are often as heavy as the child and it leads to frustration at not being able to cycle. Frog's lightweight bikes are a great confidence booster and although they may cost a little more than your average catalogue or 'car parts store' bike, the ease of use and enjoyment they'll deliver to your little person makes them well worth the extra.

    Buyers Guide

    Why buy a Frog 40?

    • Lightweight but sturdy frame, making the bike easy to manoeuvre for your child and easy for you to carry
    • Tektro brakes with small, easy to reach brake levers. Better control means improved confidence for young riders
    • Patented Frog cranks for easier pedalling reduces the distance between the pedals increasing efficiency and comfort
    • Free 5 year warranty on frame and forks
    • Reflectors, mudguard and bell included
    • Although a few pounds more to buy than a heavy catalogue bike, the residual value when you come to sell a Frog generally means you get something back unlike many other kids bikes.
    • The Frog 40 and 48 can also be used as a balance bike for a taller child by removing the pedals.

    Sizing Information

    How do I know which Frog bike will fit?

    In contrast to many children's bikes, Frog bikes are sized by the leg 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 each age.

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

    1. Stand the child in socks against a 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, in cm.

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

      Minimum inside leg (cm) Approx age Wheel Size Frame Size
    Frog 40
    Frog 48
    Frog 52
    Frog 55
    Frog 62
    Frog 69
    Frog 73
    Frog Road 58
    Frog Road 67
    Frog Road 70


    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 backwards and forwards on their rails. (These adjustments are easy to do and just need an allen key; instructions are in the manual).

    With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

    You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


    With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

    So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

    Estimated Delivery Dates

    Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

    The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
