This depends on how many bike spaces you wish to install. Based on a 10 space cycle rack (so 5 spaces at the bottom and 5 at the top), here are some figures:
Height of the stand without a bike 2060mm.
Minimum height requirement 2600mm.
Depth 1810mm.
Width of the stand 2015mm.
Minimum width required 2190mm.
Centres 375mm.
Finally, we recommend allowing a space of 1500mm in front of our Double Decker Cycle Stands, this gives 1080mm of manoeuvring space for users and 420mm of space for the top shelves to fully extend.
