One of the largest perks to this new breed of bicycle cup holder is that they are now easier than ever before to install. Nearly all of them come fully assembled, and require no tools to mount. Often, there is simply a bracket that you screw shut and it mounts onto the frame with ease and detaches just as quickly. There is no permanent damage to the bicycle, and thanks to the rubber coating that often is found on the mounts of these cup holders, there is no worry of the product slipping or falling off.
