I have a 25 mile commute one way, and I love my morning coffee. I was wondering if there's a bottle/cup holder made for a bike that will fit a ordinary thermos (at minimum 20-24 ounces) of HOT coffee? I was using a regular 16 oz coffee mug with my regular bottle holder, but I was finding the seal on it was shot and it was spilling all over the place, it may have been okay if the mug sat tight in the holder but it was loose. I have a very basic "skinny" 20oz thermos that won't leak but it makes too moves around in the bottle holder too much.
So, coffee drinkers..how do you carry your coffee on your bike?
