Lake finish gantry in Erg3D, sunset light over the water.
Open beta. Concept2 RowErg, plus any rower that speaks FTMS (the open Bluetooth profile for fitness equipment).

A lake beats
staring at a wall.

Pair your rowing machine over Bluetooth and the boat moves with your strokes. Pick a lake or a marshland river, set the AI field to whatever pushes you that day, and row. Live multiplayer is the next thing we ship.

Your Erg. Your World.
Race Anyone, Anywhere.

Erg3D connects to your ergometer and drops you into immersive 3D worlds. Row rivers, bike mountain trails, ski alpine runs. Race friends or strangers in real-time multiplayer, track your progress, and turn every workout into an adventure. Compatible with indoor rowing machines, bikes, and ski ergs. The ultimate indoor rowing game, and so much more. Connect. Race. Repeat.

Concept2 RowErg over Bluetooth today. More ergometers on the way.

Mountain lake course in calm weather with reflective water

A lake or a river. Pick one.

Two worlds today: a mountain lake and a marshland river. Six weather presets per world change the water, the wind, the light. A foggy morning row and a sunset row feel like different sessions.

Something to chase, every row.

Set the AI field to whatever pushes you — recreational on a bad day, World Record pace if you want to suffer. Your fastest 2K replays as a ghost boat next to the bots, so you race yourself. Free Row drops 3 to 16 ambient ghost rowers around you when you just want company. Live multiplayer is up next.

Look how you want to look.

54 rowers to pick from, each its own 3D model. Pick a boat, a world, a weather, a camera angle, then go. There are five cameras if you have an opinion, or an auto-rotate that cycles them every 15 seconds if you don't. Rowing first; kayak, canoe, stand-up paddleboard (SUP) and ski are on the roadmap.
