A springy seat retainer assembly for a bicycle comprises three sections, namely a seat post member (20) to be entered and clamped in a seat tube, further a movable intermediate section (3, 4), and a seat attachment part (2) having attachment details for a conventional saddle. The intermediate section comprises substantially parallel bars (3, 4) each being journalled both on the upper portion of the seat post member (20) and on the seat attachment part (2), as well as a springing mechanism mounted in between two diagonally placed bearings (23, 28) to push the seat attachment part (2) upwards. When the rear wheel receives a shock, a very good compensating cushioning movement directed obliquely downwards and backwards is obtained.
