Technical Information

Steel frame designed by B'TWIN. The lowered frame geometry makes it easier to get on and off the bike.
6 gears. Ultra-soft shifter for children: change gears using a grip shifter, which is easier and safer (children don't have to let go of the handlebars to change gears). B'TWIN selected this shifter as it is sized for children's hands and is extra soft.
Semi-raised stem and handlebar. Quick-release saddle. Comfortable, reinforced (plastic shell) saddle provides a comfortable sitting position. Fast, tool-free saddle adjustment. B'TWIN has selected this reinforced saddle for its tried-and-tested durability (should the bike fall over, for instance).
Ultra reliable V-Brakes. B'TWIN has chosen to equip this bike with V-brakes for their ease of use and maintenance, and excellent braking power.
B'TWIN full chainguard with designs inlaid in the plastic. The chainguard offers increased safety by reducing the risk of injury on the chainwheel.
Accessories / equipment
Equipped for riding on public roads (lights, bell, reflectors). The rear derailleur guard protects the derailleur from damage in the event of an impact.

Product is good, but I would have bought my bike in any local shops instead of decathlon,When I needed some accessories or spares, decathlon has no stock, and their inventory is inaccurate. Will not recommend decathlon for bikes.

Good Morning Murugan,

First of all, thank you very much for your feedback. We value your comment dearly and would like to express my apology to you here. We're clearing stocks for 2018 while waiting for the new 2019 range to come in, we don't have an exact forecast for all the deliveries but you can check our online store for stock availability by end of March. After the issue is solved, we can assure you that you will be able to find what you need when you come down to visit us at the store as long as we are carrying those certain products in Singapore.

Hi Ms Laetitia! Glad to see that your son enjoys the bike! We have a 24" model of the bike in black/green colour (Rockrider 700) that you may consider after your son reaches 8 years old. Hope to see you again soon! :)
