Road Chains

The bike chain, a consumable to change regularly

The bike chain, an assembly of metal links, is the element that will allow the transmission of energy between the pedals and the rear wheel.
It comes in several colours, several finishing touches, some are equipped with a "quick fastener" which facilitates the assembly and dismantling of the chain, open links... Prices are very different according to criteria such as solidity, weight, resistance to wear, etc. Be careful when choosing the chain: buy your chain according to the number of speeds on your bicycle cogset.
Regularly checking the chain for wear is important because rolling with a worn chain will make the gear change less flexible and will cause premature wear of the cogset and chain ring teeth, which normally have a much longer durability than the chain.
If you take too long to change your chain, you'll also need to change your cogset (or your chain rings) at the same time! In extreme cases, you might even fall if your chain breaks at full force!
Small tip to see if the chain is very worn: place it on the large chain ring, and pull with your fingers. If the chain is worn, it will easily lift up, leaving a good part of the teeth visible. Otherwise, it will hardly rise. Indeed, the chain lengthens as it ages.
On our site, you'll find a large selection of bicycle chains among the best brands and many models: KMC, Sram, Shimano.

Choose your child's BMX

The choice of the bike frame's size will depend on the driver. As an indication, here are the correspondences between children and bicycles that we propose:

  • For a child whose size varies between 100cm and 120cm, the wheels from 12 to 16 inches will go very well.
  • For a child between 121cm and 149cm, choose bikes with wheels between 16 and 18 inches.
  • Finally, for the larger ones measuring more than 150cm, the BMX wheels must, at least, measure 20 inches. 

These bikes have been specially designed to ensure maximum safety for your child's cycling. With their wide tyres that guarantee excellent stability and effective front and rear brakes, BMXs for children can easily suit their tastes at any age. So make your choice on!

On our site, you'll find the child's BMX that will suit you among the best brands as well as many models: Chase, Haro Bikes and Position One.

Whether it's for learning, for pleasure of merely cycling, or to already perform, nhere is a refined selection of safe and stable bikes for your child from 3 to 12 years old. We also advise you to equip yourself with a child helmet because safety is paramount.
