We doubt you will be able to achieve a full charge just by cycling around the block, but if you wanted to maintain your battery levels, or perhaps prevent it from going down too much while you listen to music or use the GPS on your phone, especially if you plan to cycle a pretty long route, perhaps the Ecoxpower might be able to do the trick. According to the product’s description, it will take about 1.5 hours for a full charge, assuming the cyclist maintains an average speed of 12mph on a bicycle with a 26” wheel. It is priced at $130 and will be available for purchase via Fancy’s website. So, any takers?
