At Mikespokes, we're all about customer service. You asked for a photo of the Superbe with the picnic basket, and by golly, we're going to provide exactly that.
In fact, here's three of them.
For the Tweed Ride and picnic this weekend, I had the basket strapped to the rack. It was a tenuous connection, and I knocked it off twice dismounting the bike. Later in the day, I saw someone with a similar basket attached simply by using the spring/clamp thing on the Plescher-style rack. This was genius... I came home and did the same and the basket was more secure and looked better.
It wasn't until I saw these photos that I noticed how "smooshed" the basket looks by the pressure of the clamp. Next time, I'll turn it around so the clamp is pressing against the hinge side rather than the open flap side.
