Will do. I bought the Lectric XP4 (70lbs). This is *not* the bike for a plane for one person, but it'll hold a 2nd person at 150 lbs, so if you aspire to carry two people, it might be one you carry.
Everyone's going to have different weight tolerances, but at 70lbs, and only a velcro strap compressing the tires together at a not-healthy looking angle, I was able to get the bike aboard, but it was above my threshold for something I'd like to do, without damaging me or the plane.
I handled a Gocycle 4, and there's a huge difference between it (38.5 lbs, I personally measured on a scale) and the 70 lb range.
@stompandgo I tried the urtopia Fold, and it was an outstanding bike. Really really solid and "tight" (test rode 2 miles), and the gears shifted properly (much better than my electric XP4). the pickup / torque was "fine." I passed on buying because I've convinced myself I need a throttle.
@stompandgo do you have one?
Just fyi, I also test rode a Velotric Fold 1. It beats the Lectric XP4 in every way (particularly the control button ergonomics), but daughter liked the color of the XP4. It's roughly the same weight, maybe slightly lighter.
Will let yall know about my next tests. (targetting sub 45lbs)
