How It Works
Head-to-head. Pound-for-pound. Max power. Winner takes all.
Two riders line up
Matched Wahoo KICKR Smart Bikes, side by side, calibrated identically.
Pick your battle
Two duration categories: 1 minute (the lung-burner) and 5 minutes (the pain cave), with more battles coming soon.
Go head to head
When the clock starts, you empty the tank. The crowd is right there. There's no bunch to hide in and no second chance.
Highest watts per kilo wins
We take your average power over the effort, divide by your bodyweight, and the bigger number takes it. Loser buys the coffee.
Why Watts per kg?
Raw power favours big riders. Watts per kilo levels the field. It's the number that actually decides who goes uphill faster, and it means a 60kg climber and a 90kg sprinter can meet on equal terms.
Everyone has a shot at the crown. You just have to bring your best.
The full experience
This isn't a spin class. It's a Fight Night - packed crowd, loud music, bright lights, and a head-to-head battle that the whole room can follow in real time.
Whether you're racing or watching, the atmosphere is electric. Come to compete. Come to cheer. Come for a drink. Come to see what pure power looks like.
