Rear Axle Chain Adjusting Assembly for the Swagtron EB5 Folding Electric Bike

Here is an essential part that doesn't draw much attention until it needs to be replaced. The rear axle chain adjusting assembly for the Swagtron EB5 folding electric bike is used to keep the drive chain taunt and rolling smoothly across the sprocket.

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