# Lean angle of a turning bicycle

I'm asked to derive a relationship for the leaning angle of a bicycle with the following specs:

• Center of gravity for bike and rider is a distance $L$ above the ground when vertical, and the total mass of bike and rider is $M$.
• The wheel radius is $r$ and the wheel mass is $m$
• The radius of curvature for the turn is $R$, the speed is $v$
