I understand that some of you have reason as to why complicate something so simple as a pannier or trailer and if you want the comforts of home just get a motorcycle and trailer and why spend money on something that is going to make you slower and a bigger target on the road maybe is not what you like,in my case i do see myself going along this way.Less just say put a 400w motor with gear reduction 2 x12v 100 ah battery even a 40w solar panel,before you ask were to charge i have a small 20 pound 800w generator.I did a simulator in ebikes.ca i put 772pounds on 26" wheels and it said 82 miles lets trow hills and wind and cut it to half that 40mph that's not a bad number.
I just want to see how feasible would it be,i will probably only use it 3 or 4 times a year but who knows what lies in the future.

Another pros is your in a city or small town park on a street no hassle,or if its raining,one of my concerns was every time i went in a store was my stuff going to be out there when i came back out.
Trailer 225 pounds
battery 100 pounds
gear let's say 100
i am 200 pounds
lets round it up to 700 that's a lot a weight.
