This newly invented product called Freelights.  
This is a no-friction bicycle light dynamo, no battery and no friction.  This produce is based on a newly invented idear called "Tumbling magnet generator", which is patented in USA and Europ and China.  There is still more than 12 years patent life to go.  Also this product is very simple idea and easy to be manufactured.

We are selling this product online (so far 20000 units are sold) via our website and Ebay worldwide.

The website is always on top search rank (within first three pages on Google.com search,  first page on Google.co.uk), search keywords: bicycle light, bike dynamo.  So you will not have advertising cost.

Due to personal reason,  I (as owner of patents) decided to sell these patent rights with this product  and  website together to a good buyer.
