Our Stop Easy system makes braking easier and provides a comfortable grip. For more natural movement, the brake lever is pressed parallel to the handlebars. While it is progressive, this innovative brake lever also provides 30% more braking power compared to a conventional brake lever. A B'Twin innovation that both parents and children love. 

Stop Easy innovation: a patented braking system designed for children

This bike is 1.5 kg lighter than our previous bikes for 3-5 year olds, but is just as durable. We're also proud to present an optimized steel frame whose lightness ensures comfortable riding for young cyclists. The shape of the frame gives children confidence: it makes it easier to get on or off the saddle, without the risk of bumping into the frame.

Frame material and shape

You can adjust the saddle height from 41.5 cm to 52.5 cm (16.3 to 20.7 in) using a BTR spanner (Allen 5), which corresponds with a height window of 20 cm (7.9 in) for users measuring 90 cm to 110 cm (2'11" to 3'7").

The handlebar is also adjustable by 4 cm (1.6 in).
Warning: Do not exceed the maximum recommended height on the seat tube and handlebar (marking engraved on the stems).

The bike that grows with your child!

Can you add training wheels? Yes, if your child needs them. Our 14-inch B'Twin training wheels are compatible with all our bikes of this size (you will need a 5 mm spanner, not supplied, to fit them).

Training wheel information

These tires are equipped with an inner tube (inflatable). 
Their shape and pattern give them good efficiency without sacrificing grip on everyday surfaces (roads, paths, lawns, etc.).
The Honeycomb design on the tires is exclusive to B’Twin.

Wheel / tire info

To prevent children from putting their fingers where they shouldn’t, the mechanical elements of the drive train (crank, chain, freewheel, etc.) are surrounded by a guard. It also prevents laces from getting caught and clothes from getting dirty. Housing material: plastic. 

Housing information

What accessories come with the bike? A bell, front, and rear lights. For better visibility, this bike has wheel reflectors (reflective plates attached to the spokes) and pedal reflectors.
To keep the bike and its paintwork in good condition, we advise you install a stand (ref.8872192).
