Social experiments aside, Planet Bike was born from the heart of a cyclist with a goal of making innovative, high quality, and practical bicycle accessories. Simply put, they strive to design and develop the best bicycle products in the world. In the company's short ten year history, they have made important product innovations within the bicycle industry. Advancements include the 4-line computer which is now a standard in the industry and the world's first self-contained HID light. Not bad for a company that ten years ago started as a one man operation. Today, while still a small company, Planet Bike continues to evolve and improve their product line with the goal of always striving to build accessories that make it easier for people to ride their bikes.

Polished Brass Finish
The SilvaBond antimicrobial protected finish has proved to be very effective in controlling bacteria, mold and mildew on surfaces. Independent laboratory testing has confirmed the effectiveness of this long lasting and durable finish.
Part two of the story takes place a few years later when Orson C. Phelps invents and patents (on July 17, 1866) his version of a rachet handcuff. The Phelps design brought the notches for the ratchet to the inside of the square bow and featured a heavier and more secure lock case. Phelps handcuffs are very well made and although the lock is not very secure it is a vast improvement over any earlier handcuff design. The example shown above is marked "O. C. Phelps Patented July 17 66" on the side of each bow. It is unknown if Phelps paid a royalty to Adams, who held the original ratchet handcuff patent. From the start, they have embraced an alternative corporate purpose which seeks to help get more people on bicycles by making communities friendlier places for the self-propelled. By donating 25% of company profits to causes that promote and facilitate bicycle usage, Planet Bike hopes to make an impact.
