two bolt are mountain bike SPD, three are road. (technically SPD and SPD-SL, but you know.. )
Depending on if you share, you can buy pedals that have a look cleat on one side and SPD on the other. Try amazon.I've never used clip pedals before. We just got a peloton and I want to swap the pedals out for ones that do both flat and clip. I believe the clips on our shoes are SPD, but when I search them, they look different (ours have 3 bolts, ones I see on-line have 2). Are there different types?
I believe all peloton come standard with look delta style pedals. To use spd, you’ll have to change pedals and cleats (and most likely shoes as most are either 2- or 3-bolt, not both). I don’t know if any two-sided delta pedals.
