It is very important that you know how to adjust your Smart ZBike so that your posture is correct.
Having correct posture during your training session can help to avoid back and neck pain, in addition to unnecessary injuries.
If you have a bicycle, the most practical thing to do is to transfer the measurements you have on it and to which you are accustomed. Keep in mind that the handlebar is usually placed somewhat higher to make it more comfortable, since aerodynamics do not apply.
Although if you don't have another bicycle, the guidelines to follow are provided. The adjustments described here are general and are usually adequate for most people. For a more detailed adjustment, go to a bio-mechanic who can study your specific case.
Make a first adjustment of all measurements, and after a couple of uses, change it as desired if necessary.
The seat height is the first thing to adjust. When standing next to the bike, the seat should be at hip height. Sitting on the bike and with your feet on the pedals, place one of the pedals in the lowest position and check that the leg is extended with a slight knee flexion.
Remember that the seat should always be flat and parallel to the ground.
Only adjust the seat height when you are not on the bicycle. Never adjust it while on the bike.
The handlebar should be at the height of the seat or a few centimetres higher, but never lower.
As for the horizontal adjustment, the correct distance between the seat and the handlebar should be the same approximately to the forearm (including hand). If you place your elbow just in front of the seat, the tip of your fingers should touch the handlebar without being able to hold it.
Once on the bike and with the hands on the handlebars, the shoulders should be relaxed and the elbows flexed.
This distance between seat and handlebar should enable you to keep your back stretched without forcing the spine.
