Anyone do VR with a stationary bike or bike trainer? I remember running across https://www.blync.bike when it was a kikestarter, and now it's actually shipping. Looks tempting, but also has that "it's a rotary encoder attached to a bluetooth radio that I could totally make myself" feeling. Plus it probably feels weird to turn without any roll on the bike itself. Still seems better for VR fitness than those slippy bowl treadmills though.
