The Tern Market Basket is big, beautiful, and easy to convert from a hand-basket to a bike-basket. It’s large enough to hold a backpack or a weekend’s worth of groceries, and it’s built to last.   This product can be used on virtually any rear carrier, on any small or large wheel bike.  As a general rule the carrier must be four point fitting otherwise it will not be stable enough to hold the likely weight of the basket contents. There are some exceptions on original fit racks on some e-bikes and folding bikes.
