Key Features of the Frog 70 Road Bike

  • The Prowheel alloy cranks are a child-friendly short (140mm) length and come with child-friendly 34/42 chainrings.
  • Child friendly 36cm-wide short-drop alloy handlebars.
  • 'Short drop' means a child-friendly shorter distance between the bar tops and the drops than you'd find with adult drop bars.
  • Minimum recommended inside leg measurement to the floor: 70cm.
  • Approximate age range: from 11/14 year old.
  • Manufacturer's published weight: 9.3kg.

Frog 70 Bike Sizing
Another example of Frog's original approach: rather than naming their kids' bikes by wheel size, Frog size their bikes by inside leg measurement. Hence the Frog Road 70 is recommended for children with a minimum inside leg measurement of 70cm (27.5 inches). This corresponds with other manufacturers' 26 inch wheel kids' road bikes, so the Frog 70 would make a great present for children from around 11/14 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.

Why this bike is great

Alloy frame
Like most better-quality adult bikes, Frog bikes are built with aluminium frames and (mostly) aluminium parts to keep the weight to a minimum to help ensure your child enjoys the best possible introduction to biking.

Alloy components
Sure, more and more companies are making kids' bikes with alloy (rather than heavier steel) frames and wheel rims. This Frog bike stands out for coming equipped with aluminium alloy forks, hubs, crankset, cantilever brakes, brake levers, handlebars and seatpost to keep the bike's weight to a minimum.

High quality Microshift brake/gear shifters
To make the bike suitable for gradients it comes with 2x9-speed gears via its Microshift gear shifter, Microshift derailleur and Shimano 9-speed cassette. To make it simpler for youngsters, it comes with just one shifter, one chainring and one derailleur. The Microshift shifter is integrated with the right-hand brake lever in a Shimano dual control STI style. Simply nudge the silver brake lever inwards to shift into a lower gear, or click the black return lever inwards to shift to a higher gear.

It's worth pointing out that opting for Microshift over Shimano shifters was not a cheap option. Frog spec'd these shifters (which retail for over £100) because they're at least as good as Shimano Claris in quality, and because they have the shortest-reach brake levers (measured from lever blade to handlebar) and the shortest gear change 'sweep', making them the best dual control shifters on the market for riders with smaller hands.

Frog drop handlebars
Frog designed their own unique bar, which is the correct width, appropriate to a small rider's shoulder width, and with minimum drop to make it easier for the young rider to switch hand position.

Two pairs of brake levers
The Tektro Oryx cantilever brakes (which we have seen gracing £1,000 adult cross bikes and touring bikes) can be applied from the Microshift child-friendly drop bar levers. The Frog Road 70 also comes with a set of Tektro auxiliary levers that enable the rider to pull the brakes when riding with their hands comfortably perched on the bar tops.

Quick-release wheels
Another original detail rarely seen on kids' bikes is that the Frog Road 70 comes with lightweight alloy quick release wheels fitted with good quality Kenda 26 x 1- inch road tyres, making this bike capable of sprinting and accelerating - just like an adult road bike.

Two sets of tyres for cyclocross conversion
To make the bike even more versatile, the Frog Road 70 comes supplied with a second set of 26 x 1 3/8th Kenda cyclocross tyres. Swapping over to these slightly wider, more knobbly tyres doesn't just give the young rider an early opportunity to take up cyclocross racing. They make the bike more fit for exploring unpaved cycle paths - just like an adult cyclocross bike. You might consider these options as the bike's summer and winter tyres.

Also, with cyclocross conversion in mind, Frog have internally routed the rear brake cable inside the frame so the cable is out of the way when the rider shoulders the bike.
