Pedal type
There are two types of clipless pedals in general: (1) mountain bike and (2) road bike!
For most beginners, we recommend starting out with mountain bike pedals regardless of your bicycle type or where you're cycling as road bike pedals are a lot stiffer and much harder to clip in and out of.
However, if you are used to sports with foot bindings like skiing or wakeboarding perhaps you can start out with road pedals.
