Hey guys. I'm getting a ventura rack for my bike, so I don't need to put stuff on my back. But I'm also interested in getting a lockable top box, so I can just chuck my stuff in there and forget about it. However there aren't any boxes which mount on the bike. I noticed that quite a few scooter boxes seem to have a generic clamp/bracket which bolts through a rack and holds the box in place. Would it be feasible to mount one of these on a ventura rack? Anything I have to worry about?
