I love my topbox.
I always hated them but this bike came with one, so I thought I would give it a try.
I wouldn't go about my business without one now. Pop the shopping in, pair of shoes for work, spot something you fancy while out and about. No problem at all. Beats messing with trying to fit a a 4-pack and a baguette under the little net thing. Fantastic.
Don't knock it till you've tried it
