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.
