Our original chain tensioner with steel roller for Coleman BT200X, CT200U Trail, & CT200U-EX mini bikes is what is known as an Original Equipment Manufacturer (OEM) product. This means that it is the identical component that is used at the factory to assemble the mini bike. The solid and robust steel roller offers an almost unlimited longevity compared to the more common rubber rollers.

The chain tensioner is an important part of the drive system and should be replaced if damaged or lost. A faulty chain tensioner can be identified by a loose chain that falls off during ride time.
