These bollards are designed to allow authorized vehicles such as ambulances, fire trucks, and police cars to pass through while preventing unauthorized vehicles from entering.


  • Safety is a significant concern for cyclists, particularly when navigating urban environments. The vertical bicycle's design allows for greater visibility on the road, as riders are positioned higher than they would be on a conventional bike. This elevated stance helps cyclists spot potential hazards more easily and be more visible to drivers, reducing the risk of accidents. In crowded or busy areas, enhanced visibility can be a game-changer for safer rides.


  • Moreover, bike racks can alleviate the issue of limited parking space in crowded urban settings. Many commuters find it challenging to locate parking for their cars, leading to frustration and increased traffic congestion. However, by encouraging more people to bike to transit stations and then board public transport, cities can effectively reduce the number of vehicles on the road. This not only mitigates traffic issues but also decreases the demand for parking spaces, making urban environments more navigable.
