Here's a trick I learned from
Machka, a forum member. I bought a Shwinn LeTour and it doesn't have any mounting holes for a water bottle. I used two hose clamps (from any automotive section) and used two pieces of cut tire tubing so that the metal hose clamps don't scratch up the finish on the bike. You can mount most any kind of bottle cage on your bike. The clamps hold the cage securely, believe me that baby ain't going anywhere. Thanks Machka!
