Hmm, an intriguing question indeed. Unconventional methods, you say? Well, I've heard tales of riders attaching IV drips to their handlebars for non-stop hydration. Quite extreme, I'd say, and not something I'd recommend.
As for energy, some claim to have mastered the art of photosynthesis, absorbing sunlight through their skin. While it does add a certain green tint to their complexion, I can't vouch for its effectiveness or legality.
Comparing these methods to traditional hydration packs and energy gels is like comparing a unicorn to a mule. Both have their place, but only one is a mythical beast.
As for innovative products, I've seen a few. There's this thing called a water bottle. It's quite popular among the non-e-bike cycling crowd. And for energy, well, there's always the good old-fashioned peanut butter and jelly sandwich. Just make sure to secure it well, or you'll be making a messy detour home.
Remember, the key to optimizing hydration and energy levels is not in the tools, but in the rider themselves. Embrace the mystery, and you'll find the answers you seek.
