Bivo Flow: Your Top Questions!

September 11th, 2025 | by Keaton Smith

Floooooooow! It’s one feature that makes our bottles unique. It’s what people often notice first and love most. 

But how does water come out that quickly? How does water pour out if I can’t squeeze? Why is there a straw in the bottle? These are great questions from all of you!

How does water come out that quickly?

Thank you, gravity! Water pours from Bivo bottles effortlessly because of gravity! We have created a venting system that allows air into the bottom of the bottle. That equalizes the pressure inside and allows for the bottle to pour out quickly and easily. No squeezing required! 

Here’s a fun, short video that shows a few ways people have figured out how to get water to pour out of a vessel, very quickly.

What’s up with the straw?

The straw is not for drinking out of, it’s for venting the air. So, if you try to drink out of the straw and it doesn’t work, it’s because it’s not intended for drinking! Also, the straw and nozzle are food grade silicone, a material we selected because it’s inert and dishwasher safe!

Why is flow important?

We knew if Bivo bottles didn't flow as well as or better than plastic, you wouldn't adopt it! Nobody wants to work hard to get their water out because you're already working hard enough on your bike! Some benefits include: 

Easy Drinking

Open and close our nozzle like any other sport bottle and simply tip and pour.

Hydrate more

It turns out, you drink more water while drinking out of a Bivo than other bottle. 

No Air

There is no air in the stream of water, so you’re just drinking whatever liquid you put inside, that’s it! 

Sharing

You can easily share the contents of the bottle, either by pouring into another vessel or right into a mouth (human or dog!)

No Squeeze

It's amazing how nice this is, especially when your hands are tired after a long descent! 

Our athletes love the flow rate and the fact that you don’t have to squeeze :) Check out why ultra-endurance athlete Cynthia Carson rides with Bivo bottles every time.

Quick tip: while the bottle does pour from all directions, it’s fastest when you pour with the “b” up. The nozzle has a Bivo “b” shape to it, and if it’s upright, it pours best.
