Mounting an "Aero Bag" on the Vendetta

When Maria and I are eating up the miles on the Vendetta, we're convinced that no other human-powered vehicle could travel our public roads this efficiently. The only thing that used to be missing from our trips was some cargo space.

Now we have a practical solution.

If you notice in the photos from Bike Sebring, Maria has an Aero Bag from Bent-Up Cycles and I have a Brain Box from Bacchetta mounted on the back of our Vendettas. I've been asked how these were mounted. Here is how I did it:

For adaptation to the Vendetta, the Brain Box is a bit easier than the Aero Bag, but both seem to work fine. The key goal is to have the bag not move around or droop down on top of your rear tire.

The bottom of each bag has a plastic sheet for stiffness. I drilled two 1/4" holes about an inch apart and an inch from the front/bottom edge of the bag. Drilling through fabric is NOT fun, but it's do-able. These holes went through the floor and front wall of the compartment. I drilled two matching holes through the backrest and put one large zip tie through those four holes in such a way to cinch the front edge of the bag securely to the backrest to keep it well out of the way out of the way of the brakes and rear tire. If you take a close look at the structures behind the backrest, this should all make sense.

You have the option to add some kind of support strap to shift some weight of the middle/rear of the bag to the top/back of the headrest. I did NOT do this on Maria's Aero Bag and it's been fine. On my Bacchetta Brain Box, there was an existing strap that made this easy. I put a ring clamp on the center back of the headrest and bolted the strap to it. I would suggest this strap if you plan to carry heavy items in the bag.

There were side straps at the front of each bag that I cut off and discarded.

There's probably a better way than this method, but so far, our bags have held up well and they provide very functional storage to the Vendetta without adding significant aerodynamic drag.

Bags on vendetta

Psychling , I always really enjoy reading your blogs and posts on Cruzbikes . The english forums discussing front wheel drive bikes including this one can be quiet sometimes , but the french forum velorizontal has regular posts from enthusiastic cruzbike owners just like yourself.

The link to your photos on Picasa come up with the message that the page doesn't exist. I've had the problem once or twice before with Picasa and photobucket too , but I've not been able to work out if the problem is with my PC.

Pics now `viewable'

Thank you, Fthills, for your kind comments. Very much appreciated.

I've gone into my Picasa albums and noted that I restricted viewing for the link I noted above. I've `unrestricted' that link so it should be available to anyone with the link address.

In this world we are an experiment of one. And your encouragement lights up a good deal of the night.

Here's mine

Yesterday I finished my custom mount solution for BentUp Cycles' Aerobag to my Vendetta.

I don't plan to put much weight in it, maybe a change of clothes and such on a lightly-packed week long tour, but I did want it to be mounted very sturdy as I plan to use the integrated water bottle holders.

I decided on an internal aluminum "frame" that could be bolted to some clamps on the headrest tubes, here's an inside pic: http://dl.dropbox.com/u/56018033/Vendetta_Aerobag/Inside.jpg

I used 1"x1/8" thick flat aluminum stock from my local hardware store. I then set the bag flat on the floor and held the aluminum up to trace the outer edge, leaving about 1.5" on each end. Cut it with a hacksaw, then put it in my vise on the dotted line that I traced and used a BIG HAMMER :) to bend each end. I'm only bending it once, it should be OK, right? AL can't be that touchy....

I eyeballed all the holes and pre-drilled them in each AL bracket. I had thought about melting my way through the wall of the bag with a heated piece of wire or a nail or something the right diameter, but I couldn't figure-out how to get the little torch in my garage working (hey, I'm a computer engineer, not a ... I don't know). So I ended-up just using the drill to make the holes in the bag -- which works OK as long as you don't diddle-dally around with drilling at slow RPM, that'll snag the fabric, just go at it with high RPM. :) Oh, and make sure to go through the plastic sidewall of the bag for something strong to mount onto.

I used 3/4" clamps that I found at the hardware store in the electrical section -- they have a steel (chrome plated?) band with a rubber gromet around them. You can see them in this pic: http://dl.dropbox.com/u/56018033/Vendetta_Aerobag/IMG_20120324_005138.jpg

I'm very happy how it turned-out. The two AL brackets didn't add much weight and the whole thing is very sturdy. Now if I can just get an idea of what to expect from the plastic clamps holding the headrest tubes, my mind will be settled. :)

Here's some more pics:

I can see your albums now !!

I can see your albums now !! . Some superb eye candy there. How does the V. handle a fast curvy descent from some of the mountains you've been climbing?

Dan - can you please identify the make of the mirror you have installed on your Vendetta's handlebar? Thank you

Mirrors ...

These are Zefal Spy Mirrors that I bought on the Cruzbike accessories page. I put two mirrors on all my bents. Absolutely essential. I won't ride without them.

Descending

The descents out here are nothing less than treacherous on any machine; bikes, motorcycles, passenger vehicles, delivery trucks, sports cars, pedestrians, etc... When I first got out here I was lucky enough to survive two bloody learning experiences. The posted speed limits are for motorized vehicles. So, after sliding along the road on my hip, thigh, elbow and shoulder while making a post 20 mph turn at 35 mph -- and going down -- I gave the whole issue some thought.

In 2 or 3 seconds an 8% descent can accelerate the bike easily to 35 - 45 mph. But a 160 degree left turn, followed by 20 yards of curving right turn, followed by another 160 degree left turn ... one needs to go slow. There are stiff cross winds from every direction. Sometimes there is water, ice, sand, ash or rockfall on the road. Often there are ascending vehicles passing other slower ascending vehicles by entering MY lane.

I'm alive today because I was lucky, not thoughtful or smart.

I take these descents slowly, carefully and as far to the shoulder of the road as is safe and practical.

There are plenty of road shrines to dead people on the side of the road. Last summer, within a 3 month period, I near-witnessed 3 fatalities: two motorcyclists and one car.

The thrill is not worth the risk.

Thanks for the quick reply!

Thanks for the quick reply! It seems much more aerodynamic than Mountain Mirrycle mirror on my Silvio.
