I haven't had a chance to take the Zero for a ride but a few friends have. I am eager for a chance to ride it for myself. The Zero is a very different kind of bike than the Quantya. Since its based on mountain bike components and ride position it is less motorcycle-like. As a designer I think that form and function are both important and it seems that the Zero design department focused on function and didnt consider form very much . These are a few of the reasons that Im not too into the Zero but if you dont mind those things it may be a good choice for the budget minded. They say that the '09 model is larger and fixes the poor chain drive system the current model sports. Im interested to see what this new one looks like as it sounds much better.
I dont remember exactly what the Blade's bugs are but I have read about the company being slow to release the latest model and some people encountering bugs. They seem to have a pretty decent product but are still working some stuff out. At this point what I have heard may be old news and they may be fine. I imagine that skadamo will have a better idea about this.
The Quantya seems like it may just make your commute, especially if the traffic is slow for part of the ride. Of course if you can charge at work you would be set. If you dont need all the bottom end snap you might have success in boosting mileage with taller gearing but you would have to talk to the rep to see if that is indeed practical.
The rep told me that they have taken bikes through mud and water and they didnt have any problems but I have no idea how wet it actually was. If all the connections are sealed (cant remember if they were) I dont think rain would be a problem.
I commute on my scooter with a backpack but I'm interested in developing a luggage bracket for this bike. As soon as I can get a Quantya for myself or borrow someones for measuring and fitting I will start. Since large side bags will add drag and mileage is already short I would like to do slim computer/ file bags on the side and a platform/ rack behind the seat. There are tons of options for legendary bikes like the XR650 and I would like to adapt some of those concepts specifically for this bike.
If anybody has a Quantya in New England and wants to be the guinea pig let me know.
