The Big Poppa is the biggest rack bag we sell, and this is the universal-mount version. Instead of a MIK bracket, it straps on with hook-and-loop, so it fits just about any rear rack rather than only MIK-compatible ones.
Everything else is the same bag: 1600 cubic inches of space, a large main compartment with an RF seam-sealed waterproof liner, drop-down panniers on both sides, and an expandable top for the days you overpack.
RF seam-sealed waterproof internal liner
Waterproof zipper on the main compartment
Drop-down expandable side panniers and expandable top
Water bottle holder that fits multiple bottle sizes
Bungee net on top for extra storage
Shoulder strap included; reflective accents
Mounts with hook-and-loop straps, so no MIK rack required
15" x 10" x 8" with panniers, 1600 ci; fits racks up to 7.5" wide
Which one should you buy? If your ebike has a MIK rack, go with the MIK Big Poppa Rack Bag instead. The bracket clicks on and off in seconds, which is worth the extra money if you take the bag inside a lot. If your rack is not MIK-compatible, or you would rather save $50, this is the one to get.
