I love bike touring and I'd like to be able to cover more distance in even less time. I happened upon the idea of attaching an electric hub motor to my BOB trailer, with a couple batteries on the trailer itself.
My question is this- I found this website which sells pre-built e-trailers. They claim a range of 15-20 miles with "nominal pedaling" on a 10ah battery. Now, I can already cover 100 miles in a day under my own power. If I doubled the batteries (now a range of 35 miles "with nominal pedaling"), how far do you think i could go?
I'm not too familiar with electric motors but if it were a gas engine, you could gear it for a higher top speed, say 22mph, so it would be only adding 4 mph or so to your regular speed.
