If you like wine and you like biking, you will love this Bicycle Wine Rack.
The handmade leather bicycle wine rack is perfect for taking wine with you on the go (note that it doesn't tend to fit sparkling wine due to their larger bottle bases). It easily attaches to any 1″- 1.5″ bike frame with antique brass fasteners, while the hidden clamps hold the bottle securely.
It will also work on a ladies step-through bike frame as long as it's a 1″-1.5″ diameter frame and there's enough space between the bars. You will need to clamp the base right near the seat post as gravity will pull the heaviest part of the wine bottle downwards.
The olive oil-treated vegetable-tanned leather will only look better as it ages. Note that the leather is light tan, not dark brown, as shown in some of the pictures.
You could even match your Bicycle Wine Rack with the Leather U-Lock Holster!
