Starting the research about electric motors to use in future prototypes, I came across Electric Motor Reference Center. “Most Def” a good addition to e.Moped Link section. AC or DC? read on….

E-solex is a french electric bike I came across the internet, all tough I am not a fan of its design aesthetic, I do think it has some clever solutions like the removable battery and its cover…The concept of taking the battery with you to charge it at home or at the office is in my opinion a MUST HAVE.What do you think?

There is a great story about e-solex at Autoblog Green

After we decide how much power we are going to need for our e.Moped, we will need to look up for batteries to juice up the electric motor. I started a little research and found three companies: Powerstream, Ultralife Batteries and Valence Technologies. I just added them to our link section.

But which is the best battery to use? How many of them do we need? How many Amps? 12 Volts 20 Volts or 36? only time will tell.

Meet the Lightning Lithium, an electric superbike converted from a 1999 Yamaha R1 Superbike. Built by Richard Hatfield, a motorcycle enthusiast and solar panel importer based in Burlingame, and Todd Kollin, from Electric Motorsport.

They used 28 LiFePO4 batteries which weight 6.6 pounds each. The conversion cost 15,000 dollars and can be seen in detail in this video.

Some tech specs to boost our knowledge are:
