You would need to look at the size of the batteries on these bikes and get a median estimate of the amount of electricity needed to charge them. For all intents and purposes, from what i know about the small batteries used for these bikes, it is not a lot of juice. There are a few companies here in the USA which retrofit upright and recumbent bikes with various types of batteries. My favorite is ecospeed--high quality stuff.
