Assuming you have decent regen capability, this could work well in city traffic...IF you don't have huge battery weight.
I guess a Li-Ion pack would pretty much take it out of the low cost category. Perhaps you could use smaller SLA 12 volt batteries. I use a 12V 7aH battery for my bike light. A bank of 8 of these would be around 70 lbs. Don't know if it would provide enough power though.

Unfortunately the way this system appears to be designed, it would have no positive gains on city traffic, and those Small SLA's would only net you 4-5mi max of ECA. (and there is no mention of regen that I came across) Li-Ions would definitely help in the weight category, but as you said, would definitely hinder the cost effectiveness.
