Introduction to Solar BikeRayce


What Is Solar BikeRayce?
Solar BikeRayce USA is an annual, international closed-course "rayce" held in Topeka, Kansas. Teams compete with vehicles that are powered either partially or entirely by solar power. These pedaled and non-pedaled, solar-assisted vehicles are referred to as "Solar Bikes".

The objectives of the event are to stimulate interest in science and technology and to raise awareness of alternative energy sources. More information about the event can be found at http://www.solarbike.org.

Who Organizes the Event?
The event is held as part of the Formula Sun Education Foundation. Information about the foundation can be found at http://foundation.formulasun.org.

Solar BikeRayce USA is sponsored by the Kansas Corporation Commission, New Resources Group, and the Mid-America Renewable Energy Technology (MARET) Center at Crowder College in Neosho Missouri.

Solar BikeRayce can be contacted by email at hq@solarbike.org.

BUILDING A SOLAR BIKE
In addition to regular bike components, solar bikes have electric motors, motor controllers, batteries, and solar panels. Additional introductory information about solar bike construction and components can be found in the Technical section of the website. Specific parameters for each class of bike in Solar BikeRayce are found in the Regulations.

Solar Bike Workshops are a good way to obtain an overall understanding of the design and construction of a solar bike. The workshops are conducted by Solar BikeRayce staff and generally are held over a 2-day period. During the workshop, the instructors will demonstrate solar bike construction using materials that they bring to the class. This is an excellent opportunity for teachers and students to gain a better insight into using solar energy and building a competition-level vehicle. For more information, please see the web page on Workshops.
