Can anyone tell me how they are installed? Is it a big effort or are there any clips or screws for easy installation.
How especially with the footrest - with most of the pictures I do see 4 screws (hexagon socket / Inbus): are there (covered) holes there already in standard fitting?

Thanks in advance.
