Designed for daily use, Frog’s City bike allows children to commute to school or simply cruise the city in comfort and style.

This versatile bike provides an upright ergonomic seating position, easy-to-mount step-through frame, 8-speed derailleur gears, a floating chain glider, full-length mudguards, a kickstand and a pannier rack, so riders are fully equipped for the city.

Swept handlebars & step-through frame

With its slightly swept handlebars and longer head tube, the design allows for a more upright, leisurely riding position. And, the lightweight step-through aluminium frame allows for smooth mounting and dismounting making the bike easy to ride and manoeuvre through the streets.

Derailleur gears

The Frog City bike features FrogFit Technology® youth-specific 8-speed gear shifters, which are best suited for moderate speeds and hills, perfect for efficient city riding.
As opposed to hub gears, the derailleur gears provide more range so riders can effortlessly find the appropriate gear and they are easier to maintain.

Floating chainglider

The floating chainglider, designed and manufactured in collaboration with Hebie, prevents clothing from getting stuck and the chain from getting soiled. And, it can be easily removed for cleaning and maintenance, without the need for tools.

Pannier Rack

The rear pannier rack is included as standard and can hold up to 25kg. A great way to transport bags and equipment when out and about in the City.

Kickstand

Frog’s bespoke kickstand makes it easy to park the bike when taking a break or when loading the pannier rack. And, is simple to fold away when no longer in use. Included as standard.

Manufacturer

Frog Bikes

is a British company specializing in lightweight, high-quality bicycles designed specifically for children aged 1 to 14. Founded in 2013 by Jerry and Shelley Lawson, the company emerged from their personal quest to find suitable bikes for their own children. Collaborating with sports scientists at Brunel University and renowned bicycle engineer Dimitris Katsanis, Frog Bikes developed child-specific bike geometry, ensuring comfort and efficiency tailored to young riders.

In 2016, Frog Bikes relocated its manufacturing from China to a 120,000 sq ft facility in Pontypool, Wales, enhancing quality control and reducing lead times. The company has received support from the Welsh Government and was honored with the Queen’s Award for International Trade in 2018. Today, Frog Bikes operates in over 56 countries, with exports accounting for more than half of its turnover.

Committed to sustainability

Frog Bikes joined the Race to Zero campaign in 2021, aiming to reduce emissions by 50% by 2030 and achieve net-zero emissions by 2050. Their product range includes balance bikes, hybrid bikes, mountain bikes, and road bikes, all designed with lightweight aluminum frames and child-specific components. Notably, Prince Louis was seen riding a Frog balance bike on his first day of nursery in 2021, highlighting the brand’s popularity and reputation for quality
