To be honest it will do it but where do you live. If you live in an area with no hills it will do great. If you live in an area that is moderately hilly you will have to do some pedaling. If there are a lot of hills you will have to do a lot of pedaling.
I heard small engine helper bikes described as being like a tandem bike. One where the other guy always pedals. I think that is a fair statement. You will also noy be setting any speed records. Most likely around 15 to 25 mph. If that is all you need, then a WW bike might be for you.
I think of the WW assisted bike as more for exercise and recreation. I personally would not commute daily on one. Unless I lived in a very flat area, and had no more than ten to fifteen miles each way.
