This works great. A little noisey in a metal cage on bumpy sections. I carry an empty water bottle in my pannier for the ride home.
I start early in the morning with freshly ground and brewed dark french roast, black. At about 45 minutes into my commute I travel down some quiet residential streets, sit up, watch the sunrise and enjoy my hot coffee for the last mile to work. This is the best part of my ride.
