When it comes to safety checking your Mountain Bike, a lot of it comes down to a visual inspection.
However, you will also need some of the most basic tools.
Above all else, the most important tools in your arsenal are Patience and Consistency.
A lot of the time, you are not going to want to safety check your Mountain Bike.
On top of that, it is going to be easy to just skim over your bike in a hurry.
This works most of the time but is a risky game with severe consequences.
By having patience with not only your bike, but also yourself, you are able to catch any potential safety issues with your Mountain Bike.
Along with patience, you are also going to need Consistency.
It defeats the purpose of a pre-ride safety check if you only perform them once every blue moon.
As you develop the habit to check your Mountain Bike, you will learn what you can and cannot get away with.
But you must first be consistent with your routine.
