Looks very nice. How does it handle with the gear on your front wheel? What's your typical consumption on electricity? What's your range?
What stuff do you take with you? 435 pounds looks like some load.
Is this an extra wheel trailer?
Use your fexible sunpower cells with great car. They brake very easily. Another one that I tested with EL:
I have some bikes with BionX systems and 13s batteries which I'm more or less happy with. (they are legal, that's the most important thing and for "bug out" you could change the console in 2 seconds and go 40km/h+)
I plan to buy a trailer (most likely the TT Mule shown below) and add 150-200W of solar power to it. Sadly half of the year is the opposite of sunny over here...
