My transportation bicycle does not have a rear rack
My transportation bicycle has a rear rack but I seldom use it
I strap a bag or other items to the top of the rack
I attach a single pannier to the side of the rack
I attach multiple panniers to the rack
Folding baskets are permanently attached to the rack
I attach panniers/baskets to the sides of the rack and I strap items to the top of the rack simultaneously
I typically have a child's seat on my rear rack.
