Why anyone would want to haul a bike around in a plane is beyond me. Ha ha, I've been doing it for 20+ years, with 3 different Montagues.
My latest and current ride is the newer Paratrooper Pro, I wanted disc brakes (dogpilot, never heard the term "windup" before, interesting, made me think) even though they are just mechanical (hard to get that juice line to fold more then once) AND the front shock. I've done a lot of trail riding with mine, and the frame holds up, all else is as stated mid range components but works just fine. That new nifty little rear rack, which doubles as a work stand, is pretty cool also.
Don't worry about the handle bar positioning, it is easy and cheap enough to get taller and shorter stems, along with different handle bars. Just be advised that the stock setup takes the least amount of room when folded, a taller stem for me would be a deal breaker in fitting into my S-7S.
Lately, since I electrified mine, I have been using it more and more, while going further and faster. Thanks to the 14 speed Rohloff hub I put it on it, it has an incredible gearing range. Anywhere from 38 mph to a stump pulling rock crawling creep. You purists who scoff at motors, fine, I get that, but to me it's a perfect accessory to an already great tool, that transforms what you can do with it. I recently have been using it for a shuttle, when I need to leave my crane on a job site unexpectedly, or like the other day when my flat bed truck ended up on another job 24 miles away. The next day I jumped on the Mont and cruised on over to get it, no sweat, got 'er done but still felt it at the end of the day so for sure got some exercise. Averaged 18 MPH, using 250 watts while pedaling at a reasonable cadence and effort. With the 11.5 AH 52 VDC battery I had that day, that works out to a range of 43 miles. That's if I took the battery to it's auto cutoff voltage, where it shuts down before excessively discharging. I have two batteries that size, plus a smaller one half the size, I mix and match to meet the mission needs. I'll wear out before all three will.
The combination of the portability, the speed which it folds, and now with the BBSHD motor drive addition (

My daily driver is a Prius (but you won't get stuck behind me driving slowly, trust me, they can move out pretty smartly when needed) and the bike electrification thing reminds me of it...... the extra weight and complexity of the e power drive is more then worth it in the long run. Toyota says it best, when they coined the term "synergy drive". THE INTERACTION OF DISPARATE ELEMENTS THAT WHEN COMBINED, PRODUCE AN EFFECT THAT IS GREATER THEN THE SUM OF THE SEPARATE ELEMENTS, or something like that......combining human pedal power with e power is awesome.
