The Adapter Shelf is a 12in x 4in platform for larger batteries that attaches directly to the Standard Shelf of a T-Cycle Battery Mount. The plate has mounting holes specific for the BionX, Falco, and Shimano rear rack batteries. It's also useful for supporting large brick type batteries.

Attaches to a T-Cycle Battery Mount shelf with 4 bolts (provided). If you have a Shimano STePS downtube battery, we make a separate mounting rail for that unique mounting system.

Made to extend the size of the platform on a Battery Mount.  With some creativity, may also be used to extend other types of mounts.
