General styles of racks include the Inverted U, Serpentine, Bollard, Grid, and Decorative.
Durability, weather resistance, appearance and functionality are important factors when choosing this material.
[5] The visibility of the bike rack, adequate spacing from automobile parking and pedestrian traffic, weather coverage, and proximity to destinations are all important factors determining usefulness of a bicycle rack, helping to increase its usage and assure cyclists that their bikes are securely parked.
They also do not offer much support, and a row of bicycles in this type of stand are susceptible to all being toppled in a domino effect.
[7] These consist of a thick metal bar or tube bent into the shape of a square arch.
At the time this was a revolution in a world of 'single-point holders' that bent wheels and offered little lockability for frames.
[9] In August 2006, it became publicly known that these stands could be defeated by prying the ring off with a two-by-four, limiting its effectiveness in high-crime areas.
Bikes can be parked in a smaller area as the handlebars (usually wider than the back of the bicycle) of every other one is at a different height (either high or low).
By avoiding isolated areas and hidden spaces, cyclists will feel safe enough to lock their bikes there.
It is also important to place bike racks far enough away from doorways, sidewalks, or paths where it may obstruct traffic flow.
Generally speaking, stands are not high enough for this and quite often have bracings and other obstructions in their construction that would prevent such use.
