Rookie 18 Pedal Mode

Rookie 18

Designed exclusively by us for bigger and taller children, to give them the opportunity of cycling.

Children can be overwhelmed trying to master too many skills at once. They need to be able to break down the learning process into easy more manageable steps, allowing them to learn at their own pace.

This is especially important for those that have learning development delays and coordination problems.

As the Rookie 18 allows you to completely adjust the bike it won’t be outgrown for several years; instead, it becomes a treasured possession that is beneficial which they love to ride.


For anyone that needs to learn to ride a bike aged 5 plus!

It’s incredibly lightweight and durable with a 6061 aluminium frame and top-quality alloy components. For children aged approx 5-years-old plus.


The Rookie 18″ weighs in at just 5.5Kg in pedals off mode with a minimum seat height of 48cm. The bike will fit kids aged four-five years plus. It is ideal for those just starting their cycling journey or for experienced riders coming off a smaller bike.

Our pedal kit transforms the bike by adding the included equipment. Fitting the pedal kit is quickly done using Allen keys provided. At just 7.1 kg in pedal bike mode, this bike will give you the performance of more expensive bikes, but with the added benefit of turning the bike into a lightweight, ergonomic pedal bike at a more affordable price. The maximum seat height is 63.5cm. Plus, since it retains the same geometry and handling between modes of operation, the child’s learning lag is virtually non-existent. The Rookie range of convertible pedal bikes is sure to please even the most discerning of parents.
