I am offering a sports bicycle, size 21, very lightly used. It has all safety features: a front light, a warning light at the back, it folds and doesn't take up much space, it can be taken anywhere with you. It has 7 gears (heavy) and 3 gears (light). It has hydraulics for bumps, so nothing affects you at high speed. It is very clean and one of the best quality bicycles 👍🏻 My price is 600.
