The Pedal Wrench can be found inside the station hanging from the steel cables. To use make sure to use both sides of the wrench and find the proper size for the pedal bolt your bike uses and fully inset the wrench into position. Once you make sure the bolt s flush with the wrench use your full hand grip to turn left to loosen and right to tighten on the non drive side*, and on the drive side* turn left to tighten and right to loosen the pedals.
*Non-drive side is the left of your bike when you are seated and the side where there is no chain and gears.
