As someone who has flown with several different Montague folding mountain bikes for over 20 years now, in a Rans S-7 no less, this sounds intriguing. I have long had a vague idea of some kind of twin boom (think Flying Boxcar/C-119) design allowing straight in loading of bikes and similar. I hope this guy didn't steal my idea. :xI see he is across the state from me in Boise, interesting.
The issue with bikes and Cubs is the door size, especially if the front seatback doesn't fold forward. Just my eyeball estimate, but if there's someone who has logged more hours flying with a bike then me, including a lot of off airport mountain landings, I have not heard about it! The Rans S-7 line just happens to allow a perfect loading and carrying of a Montague, along with the usual camping gear etc. My plane lands slower with the bike onboard, it likes that CG, so unless I have a passenger (the rear seat is out when I haul the bike) it usually goes along. And even when ski flying, the bike is often along, as at some point getting to a breakfast or lunch spot is usually involved. Plus , though it's always a showstopper when you taxi up anywhere in a wheel retracted ski plane, then getting the bike off and zooming off in under 3 minutes is a further "never seen anything like that before" moment.
Just last weekend, in Afton for breakfast, for probably the 200 th. time (been breakfasting there since my ultralight days 35 years ago), rather then make the 3 minute walk across the highway to the cafe, I decided to get the bike out and ride further into town. Now converted with a mid drive e motor and battery, it's utility is nearly motorcycle like, while still dead silent and still able to be pedaled easily. Then, one of the city streets leading up into a big canyon to the east caught my eye, and one thing lead to another and 5 miles later I reached the trails end. As often happens when the bike is along, I discover unexpected things.....like on this ride, the big hydroelectric penstock running up the canyon, along with their turbines, which, as a small hydro electric owner operator myself, I find fascinating. Point being, having my ride along with me has made my flying experiences immeasurably more rewarding and enjoyable. Not to mention being able to get my own mogas, and at the end of the day, COLD BEER!
