Hahaha! Well, bloody hell - what ever would you expect? All e-bikes are a compromise - the more power you use, the more battery capacity per mile is needed.WHOOPEE!.....what about the battery? or are you saying this kit would convert a standard 905SE. I suppose the current draw on battery would be significantly more, and range compromised.........
Of course, you don't HAVE to use all that power, and then you'd have the range. Maybe knowing it's there might be enough - though I'm afraid if it were me I would just have to open the throttle....
