^ with the above post. There are several accepted touch stones for the beginning position from which to fit you to this bike. One is that, generally, the forward knee is over the pedal spindle when the forward foot is at 3:00 (right) or 9:00 (left). You can research the particulars for "KOPS". This isn't absolute gospel, but it's a reasonable start. It's difficult to assess with your cranks set as shown, but I'm guessing that your saddle can go backward and lower. The back may be ~2 cm or so and the downward must be adjusted accordingly. It might be 2-3 cm lower, but you'll know by using the ball of the foot on the pedal at 6:00 and the knee slightly bent.


Your weight should be balanced between the downward force on the pedals and the portion carried by the saddle. You should be able to lift your hands to allow them to float or gently rise from the bars while riding. More like the way a jockey rides, if this makes sense.
