At 780mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2020 Junak 121 FL, with a relaxed knee angle of around 120 degrees and a forward-leaning riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
