Don't know how I ended up here, I did search for Lifan engine, but I did. Anyway....if anyone is still thinking about this, I have a "semi hybrid" rig that works well. I use a 48 volt hub motor, but instead of using the 80# pounds of 20 amp hour batteries, I used 7 amp hour batteries at maybe 20#. I used a 31cc weed eater motor driving a permanent motor to recharge the batteries. Aside from being lighter than a genset, the neat part is the batteries will start the motor too. I can get about 6-8 miles on just batteries for bikepaths, or unlimited range for longer trips. I also used an unregulated delco alternator, but it was much heavier and larger than the PM motor. One change I am making is to use a 25cc honda 4 stroke to power the motor as soon as it gets here. With the batteries as a buffer, it doesn't take much to keep them charged overall. I can furnish pics and more info if any one is still interested.
