Sorry, I thought I had responded. You can see a number of them on Amazon. Search "center kickstand with two legs" or "kickstand for bikes" to see a larger selection.

For the rear rack, I used: Adjustable Touring Rear Back of Bike Carrier - Pannier Luggage Rack with Extended Wings - Light Aluminum - Load Limit 55 lbs/25kg

again, I got off Amazon. I bought it for two features, it folds out to be wider (so I can strap on my backpack and it had a mount for a rear tail light.
