Bumping this thread, Bikerdoc, as I was in the Shanghai scootermart today and found several sizes of the Adlo box line for prices between 120 and 160 RMB -- about what you said you paid. They look very good, and I'm merely wondering which size to get. I'd like to have a top box for riding around town when I don't have the big Tourfella side boxes installed. It looks like these boxes are very easy to remove (with the press of a button), but are relatively secure on the bike as long as you've used the key lock.

Is that indeed how they work? Or could they be easily removed while locked? That would be a stupid design.

thanks
