I ride my Elby to and from work every day (love it, by the way). I always carry locks, lunch, and a few other small items. I’m currently using a rack bag from my last bike, something designed to fit a grocery bag. It works great for my purposes—easy to throw stuff in and be on my way. However, it’s wearing out & is maybe not the best fit, physically, for the Elby rack. So I’m curious if anyone’s got recommendations for a replacement?
