Are there any standards written around bicycle racks?1

Yes. Australian standard AS2890.3 is the guide for the industry. It covers most aspects of bicycle parking facilities, from the design and layout elements for parking facilities to levels of security. The full document is available from SAI Global.

What are the different security levels mentioned in the standard?1

The standard gives 3 levels of bicycle parking security:

Class 3 bicycle parking allows for the bicycle to be frame and both wheels to be locked to the rack using the owners own locks/chains.

Class 2 bicycle parking allows for bicycles to be stored in a 'communal compound' that features controlled access such as a locked entry gate.

Class 1 bicycle parking allows for bicycles to be completely enclosed in an individual, key-locked locker, protecting the bicycle from view and weather.

What is the ideal spacing between bike racks?1

Australian standard AS2890.3 suggests a distance of 1.2metres between bike racks.  However, with demand for bicycle parking increasing, and increasing space constraints around city buildings, we have seen several large city councils reduce that distance to 1.0metre.

How many bike racks can we fit in a typical parking bay?1

In a typical 2400x5400mm parking bay, we can install up to 3 racks, allowing for 6 bikes to be parked (one either side of each rack). In two bays, side by side, we can install eight racks giving us up to 16 bicycles.
