This requires loading through the main doors but. I purchased two Montague folding mountain bikes. Purchased and installed the Bafang BBSHD mid drive kits. Added 52 volt 21 amp hour battery for each bike. The bikes without battery attached weigh just under 50 lbs each. They have 50 plus miles of range (with me at 6’04 230 LBS) and can do plus 30 MPH. For under 3K each (price the average e bike) this is a deal. For that you have full size folding e bikes with great range. In the -10, we had both bikes and full camping gear in the plane. Takes only a couple minutes to set them up. Great for exploring little airports with little cool towns since most have no form of transportation at those airport. This bike set up fits in a kit fox so should worth in -7s and up.
