No offense but it never ceases to amaze me that people would rather trust the opinion of a bunch of people they've never met on an open Internet forum rather than try out the products for themselves at well known and respected retail outlets. I mean, you are going to get 20 different answers recommending 20 different bikes, just look at the 'E-Bike of the Year' thread.
In fact there's your answer all the votes are in and the Wisper 905 is your best choice. Job done.
Sorry to sound a bit off I really don't want to but buying an E-Bike, like buying a car is a personal choice....you wouldn't buy one blind, so why not go and try the bikes out listen to the sales advise, reflect on it... and by all means come back here and cross check with others experience... and then make your decision.
