The Stromberg Carlson BC-202BA is a two-bicycle platform rack supplied with a bumper accessory receiver. It can be fitted to a suitable 4- or 4½-inch square welded steel RV bumper, or installed in a compatible 2-inch receiver. The factory exploded diagram identifies the bumper adapter, lower plate, wheel cradles, frame and tie-down components.

Use the drawing's own numbers: the BC-202 and BC-202BA manuals do not use identical callouts. In particular, #14 on BC-202BA is the bumper adapter, not the right wheel cradle shown as #14 in the BC-202 manual.
Manufacturer service parts
The service numbers above are for individually identified parts. The full rack, with its bumper adapter, is linked at the top of this page; individual service components are not shown as in-stock products unless a NewRVParts listing is available.
Check the RV bumper before installation
Stromberg Carlson specifies the bumper adapter for a continuous, welded steel RV bumper. Position the adapter on the upper face, place the lower plate beneath it, and secure the assembly with the four long mounting bolts and nuts shown in the manual. Then attach the bike rack using its hitch pin, retaining clip and securing bolt.
Check that the bumper and RV manufacturer allow the combined rack-and-bicycle load. Do not exceed the 80 lb bicycle capacity, and secure the wheel-cradle straps on every wheel. This rack is not tested or approved for electric bicycles.
