Thanks, man! That is super, super helpful. I can put it in my apt, but that's a drag as is a studio. Also, I need to bring it up a couple flights of stairs, thus the desire for lightness (or maybe walk assist)? Man, 3 bikes! You must have a ton of space, am jealous. I think 50 mile range would be fine. I was surprised to see you say bigger wheels are weaker, would have thought the opposite. Thanks again!
