Single-Speed Bicycle Chain Replacement

简介

This guide demonstrates how to replace the single-speed chain on the Bambike Mira Nila Bolt, which is famous among users for its comfort and looks.

Since this bike model can't switch gears, the chain is considered a single-speed chain. This chain makes it possible for the pedals to move the bike wheels.

Replacing the chain is important because a worn-out chain can cause damage to other vital parts of the bike. A chain can even fall off if it isn't replaced in time. If you replace your chain, you not only prolong the life of your bike, but you also ensure your safety while riding.

Please note that this repair can become messy when touching various bike parts.
