Exercise bikes are a lot of fun, and having one at home can keep you fit and give you an hour to escape day-to-day life. Like anything mechanical, exercise bikes can break and, over time and require maintenance.

What Tools Will You Need?
To remove a crank, all you will need is an Allen key set and possibly a screwdriver. We recommend a long Allen key set as they offer much more leverage.
Step One: Locate The Crank Bolt
The first thing you need to do is locate the crank bolt. This will be directly above the crank arm itself at the top. You will find it by going to the center of the cranks, and it will sit on either the left or the right.
Loosen The Crank Bolt
Now we need to loosen the bolt itself. You have to take the Allen key, insert it, and then you need to turn it anti-clockwise to undo it. Expect this to be quite tight, as it’s the only bolt that holds everything together on many cranks.
Many people say to loosen the bolt, but I recommend completely removing it as it is going to help us take the crank arm off fully later. Once out, put it in a safe place, as these can sometimes be unusual threads.
The last step is to remove the crank itself. Now the bolt is out, it will be looser, but it still might take a bit of persuasion. It comes loose easily by rocking the crank back and forth, but this can take some time.
If you get really stuck, you can use the screwdriver and put it between the small gap at the top to open the gap, and it will be looser and easier to pull off. Once the crank arm is off, then put the bolt back in but not tightly, and you’re done.
