That is one sweet looking ride. (I see that you have corrected the saddle tilt )I snuck away from the grandchildren long enough to head out on the Watt Wagon to a nearby lake. If was the fastest, funniest, least amount of energy and most smiles per mile bike ride I've ever had. I'm not anal about my mileage but compared to any of my other bikes this has to be the most green bike I own, I just go by battery used on the same trips I do on a regular basis. It's also the quietest and best handling bike I own by a large margin. I'll post a real review when I have rime.
Please don't forget to give us your detailed review when you have the time.
Ride safe and enjoy
