Stainless steel bottles for turbo sessions, spin classes and Zwift races. Fast flow when you're breathing hard, and cold water an hour into a sweaty garage effort.
Indoor is unforgiving. There's no descent to coast down, no junction to soft pedal through. Every second you spend fighting a bottle is a second off your power.
Our nozzle uses gravity instead of squeeze. Developed with an ex-NASA engineer, it moves 621ml in 8.5 seconds from the moment you tilt. Pop it with your teeth, drink, put it back, hands never leave the bars for long.
No squeezing matters more indoors than out. Try coordinating a hand squeeze at threshold and you'll see why.

Indoor riding is hot. No wind, no airflow, and a bottle sitting inches from a radiator of a human being.
Plastic bidons go lukewarm within twenty minutes. The insulated Trio and Trio Mini use double wall vacuum insulation and hold cold for 12 hours and more, so the water at the end of a two hour session tastes like the water at the start.
Fill it with ice before a hard set and it will still be there when you need it most.

Indoor training is the fastest way to destroy a bottle. Heavy sweat, constant electrolyte mix, then straight into a bag or left on the bike overnight.
Plastic absorbs all of it. Cloudy, stained, faintly sour, mould in the valve within a season.
Bivo bottles are stainless steel with food grade silicone components and every part comes off, nozzle included, so you can actually clean out what you've put in. No staining, no smell, no plastic taste. BPA, BPS, BPF and phthalate free, and 100% lead free.
Universal cage fit, so it goes into whatever cage is already on your bike. On a smart bike or a studio bike, the wider holders take the full size bottles without issue, and the Trio Mini drops into narrower ones.
If you run a bar mounted holder for turbo sessions, the 500ml Trio Mini is the easier fit at 220mm tall.

Same demands, less control over the room. You can't open a window in a studio and you can't refill mid class.
Take the insulated Trio and it will still be cold in the last track. The anti-slip silicone exterior means it won't go anywhere when your hands are soaked, and it goes back in the holder without the clatter that makes everyone look at you.
The insulated Trio and Trio Mini. Double wall vacuum insulation holds cold for 12 hours and more, so water stays cold through a full session in a hot room.
All our bottles are a universal cage fit. Studio and smart bike holders take the full size bottles, and the Trio Mini at 220mm is the easier fit for narrower or bar mounted holders.
Yes, and it's easier than a squeeze bottle. There's no hand squeeze to coordinate, so you tilt and gravity does the work.
No. Stainless steel doesn't stain, absorb or hold smells, and every component separates for a full clean.
Most riders get through 500ml to 1 litre an hour indoors, more in a hot room. Two bottles within reach covers a long session.
The silicone exterior on the coloured bottles damps the contact, so they go in quietly rather than clanging.
Heading back outside? We build for the road too, alongside the full range of stainless steel sports water bottles.
