All you need is a bike.
Sol Cycling is an interesting MMO in that it is played almost entirely with a bike. As an exercise game, you play as a courier on Mars transporting goods. Your in-game character is controller through the use of a heart monitor with a spin bike or a trainer with a regular bike.
Now is the time to try SOL Cycling. Our new demo is feature rich! It offers two multiplayer gameplay modes, Free Ride or Race, so you can stay fit with friends while you explore the same Mars terrain NASA’s Perseverance Rover is exploring right now!
