Chain tensioner spring for the Razor E200 & E275 (Versions 36+) electric scooters. A broken chain tensioner spring renders the electric scooter useless, so consider ordering a few of this high failure item. At our already low price, you may want to order an extra to keep as a spare.
I wish I figured it out that all I needed was this spring before I destroyed the motor. (Straightening the frame) . Very inexpensive fix , even replacing the motor. Razor is like new again .
