Product Description

Details

Frog 52

Like the Frog 55, the Frog 52 is an easier rolling, lighter weight 20 inch wheel kids' bike. However, with its slightly smaller frame, the Frog 52 would be a safer option if your 5 or 6 year old can't comfortably clear a Frog 55 top tube.

Offering different sizing options - even when the bikes have the same wheel size - is a perfect illustration of the extra care taken by Frog - a new British company specializing in better quality kids' bikes.

As an example of their original approach, rather than numbering their kids' bikes by wheel size, Frog size their bikes by inside leg measurement. Hence the Frog 52 is recommended for children with a minimum inside leg measurement of 52cm (20.5 inches), so it fits children from 5/6 years old. It comes with a long aluminium seatpost with a quick release seat binder to make it easy to adjust the saddle as the child grows all the way up to 8 or 9 years old.

Lighter Weight
Frog bikes, like better-quality adult bikes, are built with aluminium frames and (mostly) aluminium parts to keep the weight to a minimum. That way your child(ren) will experience maximum joy riding one of these bikes.

Faster wheels
Another original detail is that the Frog 52 comes with lightweight alloy quick release wheels fitted with good quality Kenda 20 x 1.5 inch hybrid tyres which will be easier rolling than the 20 x 2 inch knobbly mountain bike tyres you'll find on most of their competitors' bikes. Skinnier tyres make a Frog bike easier to accelerate and hence more fun to ride.

Second pair of tyres
Having said that, if you young-one wants to get more adventurous, you'll be delighted to hear that the Frog 43 comes supplied with a second pair of knobbly mountain bike tyres. That way, a simple tyre swap will make the bike fit for dirt tracks and trail centres.

Colour choice
Technical attributes aside, this is no ugly frog. Frog bikes look good, so your child should be really proud to own one. To help ensure the bike delights, Frog bicycles are available in a choice of colours.

Frog Video
Frog's passion for making better bikes for kids shines through in this video.

'Frog Bicycles
We are a small British company dedicated to making cycling fun for children. We believe that the lighter the bike, the easier it is for children to learn to ride, and to enjoy it more as they progress. Many children's bikes on the market weigh nearly as much as the child! So we set about re-designing the kids' bike, sourcing a light but strong aluminium frame, and hand-picking components that offer a high performance without compromising the weight. The founders, Jerry and Shelley, are a couple who have 2 small children of their own – both keen cyclists. So they know something about what motivates children to get on their bikes! Since the first prototype arrived, the bikes have always been robustly tested by the children and all their friends.'

Spectacular, excellent, the best. My daughter's words after owning the bike for just over a day. A day in which she rode over 10 miles to visit here grandpa. Worth spending extra on a light weight quality bike. (Posted on 15/04/2015)
