MX350 bike versions can be determined by locating your bar code ID on the bottom of the frame or on the battery cover. The 7th and 8th digit in the series will tell you the version of your product: 01=version 1; 02=version 2; 09=version 9, and so on. Please be sure you identify your product version before placing an order for this wheel. NOTE: NOT compatible with units that have a serial number beginning with "MX". |
