500 Series Racks/Fenders are not available for separate purchase.
The rack and fenders are only available as an add on at the point of sale.
It is always possible to order 3rd party racks and fenders on your own after purchasing your 500 series.
There is a Ride1UP Facebook Owner's Group which has a lot of great resources for accessories that are confirmed to be compatible by other riders.
All new 500 series, Core-5, and LMT'D bikes can integrate most standard rear racks without any additional parts needed. The rack below works without anything additional needed.
FENDERS: The 500 series has standard mounting points for fenders. We suggest supporting your local bike shop or sourcing these online. You will want a minimum width of 55mm to ensure good coverage.
