Re: Montague folding bike conversion to electricty

The pictured bike is a Paratrooper, the new one is a Paratrooper Pro. Either are ideal for either a Bafang BBSO2 or BBSHD conversion from Luna Cycles.

Awesome. Thanks Tom. Now I gotta try to convince my wife that I need one of these...

Rather then drive (70 miles, one way) I flew a bit over 30. then, 5 minutes after landing and assembling the bike and trailer,clear across Idaho Falls to the trailer place, breakfast on the way back, effortlessly, and fun. The folding Travoy trailer is also working great, can't even tell its there. I'm coming up on 500 miles TT now between my plane's Montague and my rough trail fat bike, and I use the e bike I keep in the crane several times week when on jobs. While I am used to the independent utility of having a bike along in the plane (been doing that for 20 years), having the motor assist transforms the experience. It is WAY more practical, as my range is greatly expanded. 10, 20+ miles no sweat, literally. Up and over a 3,000' mountain range, piece of cake.

There is a real nice synergy between the plane and the e bike, several times now, most days actually if the weather and work schedule cooperates, I fly AND ride. Flying low and slow is a great way to find new bike trails, biking some where is a great way to check out a new LZ. I am absolutely no exercise freak, and have never had a weight problem, but damn these things are oddly funner then hell, and since I am peddling 99% of the way, I am losing a few lbs. Screw that...more importantly I can easily cover vast amounts of terrain after landing the plane, lack of ground transport has always been the bugaboo of pilots, I seem to have that licked, or at least abrogated quite a bit. It makes the whole flying thing, even better.

My new, re purposed anyway, fire resistant genuine US Air Force insulated flight suit battery containment and transportation system, on the lift strut. I cut the legs off the suit (I never used it except for a couple times, it's major drawback for winter flying was that it was too warm, and you had to take your boots off to take it off, awkward going into a cafe). It's made of Aramid, and thanks to we taxpayers is absolute top quality, sewing the ends shut and using the existing zipper made it a perfect battery bag. I have two, though one is only needed for 20-30 mile rides. Unlike the cheap hoverboard batteries that have been in the news lately, these Panasonic and Samsung quality cells have a good BMS (battery manage system), nonetheless hanging them from the strut ensures no chance whatsoever of any problems in flight. I may make a couple of mini pods, streamlined with spinner caps perhaps, but just strapping them in place seems to work fine. Note fender on forward baggage floor, it fit perfect, barely.

I got a mini baggage pod mostly installed, primarily as a way to carry my lithium ion bike battery/batteries out side the airplane. It's 2 lbs. 13 oz., including the strut mount I made. The pod comes off in a couple minutes, the mount a few more. For now I'm just using pipe wrap tape to secure it, plenty safe, it just looks like hell. The main thing is NOT scratching the lift struts, and I used some thick weatherstrip material left over from my HydroSwing door install to prevent any remote possibility of that. It looks better and is lower drag then the way I was doing it last year (yesterday I guess). THIS year I won't ever carry any batteries inside the plane, though these are high quality and protected by a quality BMS, I just don't need the potential hassle. Now I can carry all 3 of my batteries in the pod, with room left over. I only carry three if going on a 30 mile plus or further ride BTW, is more then good for 90% of my rides.

Re: Montague folding bike conversion to electricty

Always an interesting thread!

So, I'm guessing you want the batteries outside the aircraft in the event they catch fire? I have no idea how much potential heat you're dealing with, or what the effect of wind blast on a runaway battery (or three) would be, but wouldn't it make more sense to mount the pod UNDER the strut? That way if they catch fire, the destruction of the pod would allow them to drop free faster, presumably with less thermal impact to the strut. Seems like the strut, while bearing the weight of the aircraft and possibly in some turbulence, would be vulnerable to thermal damage/failure.

Maybe it doesn't matter. Just curious.

Re: Montague folding bike conversion to electricty

I really didn't have an option, the pods have a flat bottom, reinforced with a metal plate, that's where and how you secure it. The access door was already in the top, so it'd be upside down if I didn't mount it the way I did. I feel good about where it's at, if I ever have a "runaway thermal event", I'll report back on how it went, :shock: .

Meanwhile, I have yet another pod I'm working on, I already have two 6" aluminum model airplane spinners I bought 3 weeks ago, and any day now I should be getting a 6" aluminum tube that I bought from an outfit that makes those spun aluminum fuel tanks. I called them and told them I wanted a 6" dia. tank, 24" long, and to hold the end caps and any fitting, just the tube. I was thinking I could cap one end off permanently with one spinner, and fashion some kind of hinging quick release for the front one. Both of my larger batteries will slide right in that size tube, even in their padded carriers. So, I'd have this sinister looking all metal streamlined front and back mini zeppelin shaped thing, and that I COULD mount on the bottom of the struts, using the jury strut bolts. But...the glass pod arrived over a week ago, so the next thing I knew I had it mounted up. When the guy in Kansas at the tank shop finally gets off his ass and sends the tube I paid for 3 weeks ago (yeah I'm pissed) I'll see what happens, the glass pod may go on the belly, or the other wing, or on the shelf or sold. Depends what works better and looks cooler, can't have too many wing pods!

One thing: the early Zeps, with their constant diameter, were draggier, I'm told, then the newer tapered ovoid shaped lighter then air machines, (think Goodyear blimp) so I think that glass one may be less drag while also offering a lot more room. But, the 24" aluminum one could mount under the belly, as I recently relocated my Swiss muffler to one side rather then down the middle, freeing up some real estate down there. My bike, when in the plane, somewhat limits my access to my rear baggage area, I may use the glass pod for extra stuff I want to easily get at during the day. I really need a side baggage door but am too lazy to build one into a completed plane.
