OSNews, Generic OSes I had the chance to attend the bike industry’s annual DealerCamp in my hometown of Park City, Utah last week. It’s an event where dealers and manufacturers can meet up, and everyone can try the latest bicycle technology on the roads and trails. While there, I took a particular interest in electric bicycles, which were represented by several vendors. Electric bicycle tech has made some major strides in the past few years, but still has a long way to go, in particular on the software side.

Member since:

Batteries have a short effective lifespan (~1000 charges). Processing rare earths to make electric motor magnets is extremely hazardous and highly polluting.

Most lithium batteries quote well over 1000 cycles to loose only 20 percent of their original capacity. They still work just 80% of original energy storage.

Most push bike motors use NO rare earth metals they are just too dear. And most of the concern with rare earth elements in batteries are derived from the Toyota's NiCd batteries... not newer LiPo or LiFePo batteries.
