Frog 40 for Age 3-4 Years Union Jack

Season:2021

Brand:Frog Bikes

Code:L-FH40-UJA

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.

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

Sizing a child for a Frog hybrid bike is an important step in ensuring a comfortable and safe riding experience. Here's a general guide to help you determine the appropriate size for your mini rider:

1. Measure their inseam: Ask your child to stand with their feet slightly apart, then measure the distance from the floor to their crotch using a tape measure. This provides an accurate inseam measurement.
2. Refer to the size chart below. Match your child's inseam measurement with the recommended bike size range provided. Take note of the age and height recommendations too, as they can further guide your decision.
3. Consider their overall height and age: While the inseam measurement is crucial, it's important to consider your child's height and age as well. This ensures a comfortable fit and allows for growth.
4. Test the bike fit: Once you've determined the recommended size, it's helpful to have the child sit on the bike and check for a comfortable riding position. Their feet should be able to touch the ground while sitting on the saddle, and they should have a slight bend in their knees when the pedals are at the lowest point.


Remember, these steps are general guidelines. For precise sizing ideally pop into the shop with your little person and we'll be happy to assist with this, we endeavour to keep all sizes available at all times but give us a quick call beforehand to check.
