The configuration of a bicycle is adjustable, but not always quite enough. For example in my case the crucial factor for comfort is the angle of the bend of my knee at the top of the pedal rotation. If the seat is too low that angle becomes acute, and causes acute pain. I just can’t bend my knees that far. It is the equivalent of doing a squat and is just not possible at present.
In order to manage this, I have to put the seat higher than I would prefer, which means I can only just touch the ground with my foot extended when stationary. This makes dismounting, and waiting at intersections a little precarious. Especially taking into consideration my inherent unsteadiness. I am getting the hang of it, but it is my most vulnerable time.
Fortunately there are so many bike paths here I rarely spend much time in traffic. I can often find somewhere to pull up by a curb, or fence, or a tree or a park bench for extra stability.
The problem manifests in another way. The tolerances are fine. Even wearing shoes with any significant thickness of sole puts extra strain on my knees. So I am reduced to wearing my Jandals or my Skinners..
This makes my feet a bit more vulnerable in case of an accident. A risk I’ve decided to take. I know that my death in a traffic accident would be very traumatic for the poor bastard who kills me, so I shall be very careful. Always thoughtful, me.
In the meantime, I am doing squats in the pool in an effort to rectify the situation. No noticeable improvement yet, but it is still early days.
