Water, the one liter size Smart Water and one liter size Life WTR disposable bottles fit well in most bike frame cages. The Life WTR bottles are a bit shorter than the Smart Water ones, both are a bit under 12 inches.

I reuse them, but after a few months they are pretty beat up. This size does not have a flip top lid for easy drinking, I use those lids from other bottles.

In winter, pre-virus I did an hour to two hours on an exercise bike at Planet Fitness a couple times a week. Their saddles are rock hard. Immensely boring, so I bring a tablet along to read the news on, downloading news articles off of wifi.
