Travel through foreign lands, or through airports with ease.

The Cyclone IV bicycle trailer by Radical Design of the Netherlands offers a brilliant assortment of features for bicycle touring and commuting. These features include excellent load balancing, multiple wheel positions lending to use as both a bike trailer and a walking trailer, and a uniquely designed heavy-duty fabric cargo area built into the trailer. This trailer is both rugged and light. It carries large loads, but is lithe and long lasting.

The bag is made of 100% genuine Cordura 1000D, and opens from all sides for convenient access to your cargo. Inside there are two internal pouches for small items that you want to keep handy.

The Radical Design Bike Trailer Hitch fits on any rear axle and is made of stainless steel. It can be ordered separately for use with multiple bikes. The Cyclone also folds up quickly for easy storage and the wheel positions offer versatility between biking and traveling. With the wheels repositioned to the rear (with the push of a button) and the hitch arm taken off (with the twist of a bolt), the trailer turns into a duffel bag on wheels ensuring easy management in busy settings such as elevators, airports and shopping centers. The shoulder strap and the two big handles make it easy to lift.

For quicker transition between traveling trailer and luggage, place the hitch inside the bag and put the wheels in their separate, attachable wheel storage bag for easier access(sold separately). This makes the Cyclone IV an easy to manage, self-contained duffel bag, ready for check-in.

To keep your trailer and its contents dry and clean, the Cyclone IV includes a lightweight fluorescent yellow nylon rain cover with a polyurethane coating. The rain cover is attaches in seconds. You can also leave it on all day for protection against dirt and road grime.

Update on 2013 review. I just completed a Boston-Quebec-Boston tour with 820 miles of touring using a classical tandem bicycle with the cyclone trailer fully loaded to 80 lb capacity. It performed marvelously. It took all of the normal mistakes of touring in stride, including running off curbs, etc, and the tour ended with straight wheels. It was particularly easy to detach and roll into hotel rooms. Some lessons learned: 1) I lined the canvas bed with a plastic stiffener to compensate for canvas stretch. 2) A lot of the width nervousness I had before was psychological. My frame bags are wider than the trailer. 3) Two flags work well and traffic stays away. 4) Sore shoulders from touring with single-wheel trailers are no more. In short, after this tour, I cannot conceive of touring with any other trailer.

Just completed 500 touring miles with the trailer fully loaded and behind a tandem. Have been tandem touring with BOB (6 tours, 500+ miles each) and ExtraWheel (one tour). Pluses for Radical Design Trailer: - very light weight. - very stable due to low center of gravity. - bike balance problems solved due to decoupling trailer from bicycle (compared to BOB or ExtraWheel). - survived a couple of fallovers of the bike without ill effects due to well-designed trailer coupling. - only trailer compatible with all of my tandems (20"/26"/27" rear wheels, including compatibility with strange wheel bolts (e.g., Phil bolt-ons)). Minuses: - cars are nervous around such a wide trailer. Worst situation: climbing up and down the Deer Island Bridge in Maine. One lane wide, not enough space for car to pass trailer. Lots of impatient motorists fortunately did not take it out on us. Badly designed bridge and the only way to get to Deer Island. - Really need two flags in order to know what's going on with the trailer: one for each side. These are sold separately. It is really easy to lose a flag bracket. After losing one and luckily noticing it fall off, I tied mine on with kevlar thread (glorified high-test fishing line). - Main trailer plaform is fabric and stretches. During the trip the platform stretched substantively. So far, it sags about 4 inches lower than when I bought it. Not sure how it will stand up to repeated use. This does not -- so far -- affect performance. - watching for three tracks (bike plus two trailer wheels) is challenging on rough roads. Trailer ended up hitting a lot of deep potholes. It survived with straight wheels. - very pricy compared to my other trailers: a BOB and an extrawheel. The bottom line: it did the job, and the main minus was the width of the trailer in traffic. Would I tour with it again? I am considering it. It is an apples-and-oranges decision: trading "ease of balance" against "handling in traffic and on rough roads". Not an easy decision to make.

The first couple of times I took my Cyclone III out, I rode with it empty for a total of about 20 miles because I wanted to experiment with it without the challenge of getting home with a load if I managed to break it. I took it over gravel, off of curbs (at an angle, so one wheel dropped before the other), through tight turns, over small potholes, through narrow passages, and up and down steep hills, and I had not the least trouble with it. (I did manage to flip it when I dropped one wheel into a pothole at about 10 mph, but the pothole was one that I'd never ride through with my bike, so that didn't seem a fair test. I flipped it back upright and rode off with it as if nothing had happened.) On my first loaded trip with it, I hauled 11 six-packs/85 pounds of beer (some of which is going to friends) 6-1/2 miles up the hills of Seattle, and the Cyclone (towed by a Brompton) handled the load brilliantly. It's easy to load, it rolls well, it hooks up to the bike in an instant, it's quiet, and it has a bunch of straps that you can use to cinch down your load, so the weight doesn't flop all over the place. When I got home, I looked under the trailer to see whether the bottom had sagged under all that weight. Yes, a little, but far less than I had expected. The quality of materials and workmanship are impeccable. I was so amazed that I showed the trailer to a friend whose response was the same as mine--awe. The hitch that attaches to the bike is so beautiful and well made that you want to set it on an end table as you would a blown-glass vase. I live in a small house, and I bought the Cyclone in part because I could take the wheels off and get the trailer out of the way. (With the wheels off, the trailer part is just a couple of inches thick. I can hide it behind my couch.) The wheels pop right off when you want them to and don't when you don't want them to. If anything, it comes apart for storage faster than a Brompton folds, meaning in just a few seconds. I had another brand of folding trailer (a brand not carried by that came with a 12-page instruction manual that said, in part (I'm paraphrasing), "You'll get faster at folding and unfolding as you practice." In retrospect, I should have recognized that as a bad sign. I didn't practice enough, and the other trailer remained a pain in the neck. The Cyclone comes with one sheet (front and back) of instructions that you almost don't need. The instructions are in four languages and include several pictures, so it's less than a half-page of documentation per language, not one word of which needs to tell you that you'll get faster with practice.

Have yet to use my Cyclone III ,but have put it together(super easy) and it is very light and should be easy to tow and exceptionally funtional. Can hardly wait for weather to break , so we can try it out. Thinking it will be a joy forever.
