Get ready to take on the world with the new Sonic Bulk, a 20” wheel fat-tyre bike for children aged 6-9.

These striking bikes feature a wheelset with 20×4” alloy rims run on wider hubs and big motorcycle-inspired tyres for powerful control and performance.

Motorcycle-inspired tyre technology means that only the top of the thread touches the road giving you a bike that rolls at speed with power and stability coming in when taking those sharp corners.

With an 11” steel frame and rigid steel fork, the Bulk is as sturdy and durable as it looks, with stylishly simple, eye-catching blue and black finish. The Shimano 6 Speed gearset offers steady power with a twist gear shifter, and the mountain bike style low-rise handlebars make the Bulk easy to handle on the street, the pavement, or the park. And with the powerful V-type brakes, the Bulk is ready to take on anything.
