Product Description


Frog 48

The Frog 48 is an easier rolling 16 inch-wheel kids' bike.

Frog is a British company specializing in better-quality, lighter weight kids' bikes.

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.

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 48 is recommended for children with a minimum inside leg measurement of 48cm (19 inches). This corresponds with other manufacturers' 16 inch wheel kids' bikes, so the Frog 48 would make a great present for children from 4 year olds. 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 7 or 8 years old.

Faster Wheels
Another original detail is that the Frog 48 comes with lightweight alloy wheels fitted with good quality Kenda 16 x 1.5 inch hybrid tyres which will be easier rolling than the 16 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 much of the time.

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 48 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.

Choice of Colours
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 they delight, Frog bikes are available in a choice of colours.

'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.'

Frog 48 ReviewReview by ianmac
After starting my son on a cheap bike and him finding it heavy and unwieldy - the old adage is true 'buy cheap, pay twice'. After doing my research the Frog 48 came out tops and the moment my 4year old got on it he was away - up hills, down obstacles, it didn't matter. Everything on the bike is set up with kids in mind. He has been on it every day for the past 2months. Excellent service from Edinburgh Bicycle and they even throw in a free first year service. (Posted on 15/10/2015)
