Abstract: A clipless pedal platform adapter can include first and second platforms. Each platform can have an outer side to interface with a user's foot and an inner side to interface with a clipless pedal, the inner sides facing one another. First and second side members can also be pivotally coupled to the first and second platforms at opposite ends of the platforms such that a distance between the platforms is variable. The first and second platforms and the first and second side members can define a pedal opening to receive the pedal. The first and second platforms can be biased toward one another to force the inner sides against the pedal thereby coupling the clipless pedal platform adapter to the pedal.
