The 9 Best Bike Pedal Wrenches
This wiki has been updated 15 times since it was first published in January of 2018. Sometimes, having the right tool for the task at hand makes all the difference in the world. If you're an avid cyclist who likes to perform your own repairs, it's probably a good idea to keep a bike pedal wrench around, even if you don't think you'll need it very often. It fits into spaces that are too tight for a regular wrench, and buying one is a whole lot cheaper than a trip to the shop.

Removed the Sunlite Sprocket, the Sablue Multi, the Diamondback 15mm, and the Bikehand Acekit because of availability issues.
It's good to periodically tighten your bike's pedals since they gradually back out with the pressure you apply when you use them. If you neglect to do so, after a certain point, only some of the threads will be engaged and the downward pressure will tear out and ruin the threads in the crank arm. Then you'll have to either retap the hole (may not be possible on some models) or buy new arms. Many of the pedal wrenches available like the Park Tool PW-5 come with a 15mm head that is machined in such a way that it may also fit older 9/16ths wrench flats. The Sunlite Sport has the 15mm slot with additional 16 and 17mm slots for more unusual pedal flats. While one should normally be wary of tools that try to fit too many functions onto one platform, the Bikehand YC-515 does this without sacrificing any one of its features. It works very well as both a bike pedal wrench and a cogset remover and installer thanks to its chain whip.
