20-inch bike with 6 speeds, front suspension, double disc brake

6-8-year-old kids (4’1″ – 4’7″)

Frame

Aluminum frame designed by B’Twin. The lowered frame geometry makes it easier to get on and off the bike.

Drivetrain

6 speeds. Ultra-soft grip shifter for kids: Change gears using a grip shifter, which is easier and safer (kids don’t have to let go of the handlebar to change gears). B’Twin chose this shifter as it is extra soft and specially sized for kids’ hands.

Handlebar / stem / steering

Mid-rise stem and handlebar.
Quick-release saddle. Comfortable, reinforced (plastic shell) saddle that provides a comfortable position. Fast, tool-free saddle adjustment. B’Twin selected this reinforced saddle for its tried-and-tested durability (should the bike fall over, for instance).

Brakes

Very reliable double disc brakes. B’Twin chose to equip this bike with a double disc Brake system for its ease of use, easy maintenance, and greater braking power.
