I am a big guy. When you put me on a short wheelbase, higher seat height bike, it is the ideal scenario for wheelies. I rode the Energicas and on the LW I could consistently get to 60 quicker. It doesn't matter what the bike is theoretically capable of with an ideal rider, it is what it can do with me when I use it.
If I there are wheelies, the power has to be cut. The more wheelie prone, the more the power has to be cut. So basically it is what amount of power can be put down. On the LW, it is lower and longer and even though it has less power, I am quicker because I can use more of it. So unless I put an extended swingarm, or wheelie bars on an Energica, the LW is going to be quicker for me at least to 60. That is where the bulk of my riding is and one of the reasons I passed on buying an Energica. The benefits it might have over the LW were not realized in my riding situation. The old adage in drag racing applies; "It isn't how much power you have, but how much power you can put down".
If I rode on more open roads, or spent my time at higher speeds, the Energica (or Damon) would make more sense. I ride in pretty dense city traffic and the LW is a great tool for that. At the end of the day I have a turbo bike and a supercharged bike that downright make the Energicas look slow. So if I really need a speed fix, I'll hop on one of those. I almost never ride them currently as they are terrible tools for the heavy traffic I deal with. The LW is a great urban assault tool for me. If I hadn't ridden the Energicas as well as the LW, I probably would have bought one of the Energicas. The test ride on the LW showed me it would be better for my riding conditions.
At the end of the day, people need to buy what is best for their usage. It may not be what others might consider to be the "best bike". For my environment, the LW turned out to be the best bike currently, although I had never seriously considered it at first and basically planned on buying an Energica Ego. If I had done that, it would have been a mistake.
