About This Bike
Simply put, Decathlon's Between Racing Boy 500 is for those kids who love to ride their bikes on dirt trails or uphill and downhill trails instead of straight roads. This bike is perfect for kids aged 6 to 9 years old, with a height of between 120 and 135 cm. The biggest plus point of this bike is its front suspension and gear combination. It has a spring suspension like a real mountain bike in front, which absorbs all the bumps on the road. The frame is made of high-ten steel, so it is a bit heavy, but it is incredibly strong. If your kid wants to do some rough and tough riding with his bike, then this will be a great ride for him.
The best combination of safety and design
Decathlon has taken the safety of children very seriously in the design of this bike. This includes their own patented 'Easy Brake' system. Usually, children have less hand strength, so they cannot press the big brake lever properly. But this easy brake lever is designed in such a way that it is very close to the handle and ensures very strong braking with 30% less force from the child's hand. The look of the bicycle is sporty like a pure racing bike. For safety, there is a smart plastic cover or guard on its chain, which protects the child's legs or the corners of the clothes. Its wheels are quite wide and the grips of the tires are quite grooved (Aggressive Lugs), due to which there is no fear of the bicycle slipping even on mud or wet grass.

Why This Model is the Best for Your Child
If you don't want to spend 400-500 euros like premium brands, but want a mountain bike with perfect gear and suspension for your child—then this is the best option on the market. There is nothing new to say about Decathlon's build quality, and they offer a lifetime warranty on their frames, which is incredible in this budget. Thanks to its 6-speed gear, your child will be able to easily change gears and ride a bicycle on flyovers or high roads. Being affordable, it will not only put pressure on your pocket, but will also make your child's adventurous childhood more enjoyable. There is no alternative to this bicycle to get the feel of a real MTB at a low cost.
Brakes and wheel control
The 20-inch wheels of this bicycle use aluminum rims and 2-tone skinwall tires, which look great and perform well. The wide tires ensure good balance on dirt roads or sand. The handlebars are riser-style, which helps the child sit upright and ride the bike comfortably. The handle has a 'grip shifter' for gear changes. Kids can easily change gears from 1 to 6 by turning the handle like a motorbike, which is very easy for little ones to understand and use.
