Hi Dirk
A couple of you might want to think about are.
The ezee has a 22 mph boost button. nominally for off road purposes, as far as i can tell the whispter does not.
Whatthe battery warranty is on either bike. Both claim various cycle lifes. The cycle life claim is pretty meaningless if the warranty period is so short that it would be next to impossible use the bike enough to get that number of cycles. The chemistry both battery's use (lithium manganese)is very new and I have seen not any information on how long it lasts. The best guesses seem to come from comparing it to the much older lithium cobalt chemistry. which is about 3 years calender life and 500 cycles.
