On your terms.

You can start guided setup checks at home with your own bike and a phone or laptop. With a compatible indoor trainer, you can also record and compare a side-on riding video. The result is a starting point for your next check, not a diagnosis.

You can start the basic route without one: record your setup, measurements and access to the controls. Dynamic pedalling analysis needs a compatible trainer that safely supports the bike. A wall or someone holding the bike is not a substitute.

Start with a repeatable measurement of your existing setup. There is no single seat-height number for every rider. Your bike, shoes, pedals, movement and reported comfort all add context before considering a change.

Record the hand position, when you notice it and whether you can operate both brakes. Several parts of your setup can affect your reach; a stretched feeling or one camera angle cannot choose a replacement stem.

Allow time to set up, gather useful observations and repeat a check if needed. There is no fixed total session time. A video’s minimum recording length is only part of the process, and the follow-up ride happens separately.

You can record a comfortable position without trying to change it. A saved starting point is useful after a component change or when comparing future observations. Keeping a setup that works is a valid outcome.
