I cannot change my pedals because of a plastic cap I cycle casually every day and I know at least something about bikes. But not that much that I know how to deal with the problem I experience.
Recently I got a new great bike (for me at least), but I noticed that the pedals were starting to get loose (issues with the thread). They are a basic plastic model, so I wanted to change them to something better.
Anyway, I got the new pedals and started working. I had an idea on how to do it, but after reading the instructions and an hour later I thought I was doing something wrong. So I watched a few videos on how to do it, and I was doing everything right.
Except this little problem...
The place where the Allen wrench should go, there is this plastic coin kinda thing, that very confidently says &quot;made in china&quot;, that blocks the hole for the wrench (at least I suppose there is a hole for the wrench behind it). There is no point in telling about the bike because it was built in the local shop and the pedals don't have a brand and it won't help if I tell you the other parts.
So my question is, how do I change my pedals?
Any help is well appreciated.
Not all pedals have hex-socket insets on them.  This is especially true for cheap pedals that come on some bikes.
You should invest in a proper pedal tool, which is a 15 mm wrench with a narrow profile, widely available from tool manufacturers. If you look closely at the area between the pedal itself and the crank you will see two small &quot;flats&quot; or &quot;lands&quot;.  This is where the pedal tool fits and you can then tighten or loosen it.
