Best of the Best: Folding Bikes

Written byHank Green on 16/12/06

 

Bicycle commuting rocks. It's healthy, safe, fast, cheap and the only emission is what the biker breathes out. But it does have it's problems. One is that bikes generally have a very awkward shape. If there is no bike rack, or if you want to go somewhere with your bike, you're reduced to lugging a very cumbersome package around with you.

 

Well what if there was a bike you could fit in your trunk, that was the size of a briefcase, or that you could take on the subway. That sure would be nice.

 

Thus, the concept of the folding bike. You might be surprised to learn that there are actually quite a lot of these guys out there. They range from the practical to the nonsensical and from frugal to near-car prices. And today, at EcoGeek, we're going to show you the best of the folding bikes.

 

 

Let's start out with the cheapest. If your loved one needs a folding bicycle this season, Citizen is probably the brand for you. First, because they're widely available in America. Second, because they're on asuper sale right now, at only $170 USD. This gives us a good example of what most folding bikes these days look like, with a low center of gravity and small wheels. 

 

And now, we move  immediately into what is honestly the strangest bike I've ever seen. TheA-Bike promises that it is the world's smallest and lightest folding bike. I wouldn't doubt it. It's about 6 kilograms and you can get one in england for about 200 pounds. But, really, is that actually going to work?  From what I know about bicycles, the angular momentum of the tires is what keeps you steady. I'm not a physicist, but it looks to me like this would be fairly impossible to ride steadily. But I could be wrong... 

 

A lot of designers seem to think "While I'm trying out one untested technology, I might as well incorporate two." And that's what happened with these next two examples. The Jacknife is a prototype folding bike that simply doubles over on itself. Most bikes can't do this because of the traditional chain/gear system. The Jacknife, instead, uses a hydraulic pedal drive. Or, at least, it says it does, I can't figure out what that means, or how it works. I guess that's why it's still a prototype.

 

More encouraging is the eZee Quando, which is both an electric bike and a folding bike. Electric bikes seem like a fine idea to me, even though I don't think I would ever use one. I mean, the speed of travel or excess of exertion is not what keeps me from riding my bike (if you're wondering, it's the snow / slush / and subzero wind chill that's keeping me in the Nissan right now.) But, electric transportation is, generally, a good thing, so I'm behind this electric folding bike.

 

The big problem here though, batteries. It's hard to claim that a bike is 'portable' when it ways sixty pounds. Apparently the bike takes on hills without batting an eye, and can go 15 mph for 20 miles on one charge, definitely father than I'd ever need to go. 

 

For someone who is maybe a little bit more hip (and wealthy) than me, there's theGoBike. I can see folks in New York City jaunting around on this thing in their nice pressed suits with passer-bys thinking "damnit, that guy is actually cooler than me." And then, when they see him get off the thing, fold it into a ball, and walk into the subway, that's when they smack their heads and realize that they are officially out of the loop. Available now for $1,500.

 

The Di Blasi R24 fits into the same category as the GoBike, as it's both functional and folds into a wadded mass of bicycle parts that will have co-workers saying "Oh my GOD, what happened to your BIKE!!" Plus, it's Italian, so there's a hottie in the picture, and they're way cheaper than GoBikes. And also not available in America, sorry. About $600 USD.

 

Moving away from the 'balls of parts' folding bikes, we have a less traditional looking vehicle, the Strida 3. We're getting cheaper now, at $300 USD and lighter as well. Good luck finding parts for it though. The bike folds in far simpler fashion than the GoBike or Di Blasi will, and ends up in a package that will easily fit in a kitchen cabinet. No word on how ridable these tiny-wheeled bikes are though. But it's got to be better than the A-Frame.

 

And coming in last, because it doesn't exist in the real world yet, is Josef Cadek's beautiful Locust folding bike. By turning the frame into a circle, the bike avoids looking like a crumpled up ball of bike parts while still being magnificently compact. Frankly, it looks more likely to be ridden by a south-going sneetch than a NYU undergrad, but, nonetheless, if it's produced, and it's lightweight, and it's inexpensive, I could see these selling like hotcakes.  And I do love a good hotcake.

 

Thanks to TreeHugger for all of the excellent resources. For more info, just go there and search for 'Folding Bike," you'll find around two dozen articles.  And for even more in depth reviews of even more folding bikes (how could there be so many) check outRideThisBike.com.

Free2Go is the world’s lightest and most portable bike rack for Smart Car owners and Smart Car users.

My name is Ryan Battle and I love to ride my bike. A couple years ago, I started noticing an influx of Smart Cars in Austin as a number of new, car-sharing services came to town. The idea of getting around without owning a car intrigued me, but I quickly realized there was a missing piece. Everywhere I went, I saw this...

This isn’t good. For the Smart Car OR the bike.

That’s why I invented the Free2Go bike rack system - the world’s lightest and most portable bike rack, designed exclusively for Smart Cars.

For people who prefer the flexibility of getting around in a variety of ways – by bike, by foot, by bus, and by car sharing services – the Free2Go bike rack makes it easy to switch from two wheels to four wheels (and back again), so you can be where you want to be when you want to be there.

Lighter than a Laptop

The Free2Go rack system (all components) weighs in at 1Kg (2.2 lbs) and can easily fit in a backpack, a bike pannier, a messenger bag or a purse.

The Softflex® strap on each mount also enables the bike rack to be easily attached and carried by the bike itself.

The Patent Pending design has been engineered for strength and durability and incorporates features that enable a wide variety of bicycle types and sizes to be safely and securely transported for wherever life’s adventures may take you.

Getting to This Point

It's true what they say. Every invention begins with an idea. What they don't usually tell you is that, in order to turn that idea into a reality, you have to go through dozens of notebooks, hundreds of sketches, countless illegible scribbles, and about a thousand revisions. 

Initial pencil sketches.

Vector based engineering comps.

The very first prototype. A.K.A. proof of concept.

For the second prototype, I turned to 3D printing. I was amazed and at how fast the pieces were turned around and how precise they were to the design drawings.

Second Free2Go prototype. Made with a 3D printer.

With a few basic alterations, I moved forward with a local metal works shop to create the threaded metal cores and then sent those off to the prototype shop to have the overmolds applied.

First functional build - stirrup and peg design.

It was with this initial functional prototype that I really started to hone in on the best design. I originally believed that the weight could be kept down by going with the rear peg approach. However, as it turned out, the peg weighed more than the stirrup because of the longer steel mass in the core.

The pegs were longer/heavier than the stirrups.

At this point, I also realized that it would be more expensive to have the manufacturer fabricate different molds for the front and back (stirrup and peg), so I simplified the design (and reduced costs) by creating two identical stirrups.

In order to get the weight down even further (so that it would be easier for people to carry), I had to find a material that was just as strong as steel, but a fair amount lighter. After weeks of research, I found 7075-T6 extruded aluminum. As you can see in the following pictures, the old stirrup (just one stirrup) was 1.8 lb while the final design of two stirrups plus the strapping system came in at ~2.23lb.

With these design changes made, I could finally turn my attention to manufacturing.

Made in America

Proudly manufactured in Kent, Ohio.

While many people have suggested producing the Free2Go in China, I don't feel that the overhead is worth the cost. I prefer having a relationship with the manufacturer along with the ability to visit the facilities whenever I want.

After months of research, my needs were met by a pair of brothers in Kent, OH who have been running a manufacturing company for 40 years and learned the trade from their father. I paid them a visit before agreeing to do business with them.

Since then, I have worked closely with the two brothers on the development of the Free2Go molds, negotiating production costs per unit based on order sizes of 500, 1000, 5000.

The molds, by far, are the most expensive part of the entire process.

Shortly following these images came a short run of test racks that were inspected with a fine-toothed comb, making sure that everything was as it should be with gate markings, nit lines, etc.

By manufacturing the Free2Go in the United States, I think it shows that sustainable innovations are good for our environment and our economy.

Ready to Launch!

Finally, after more than two years of research, prototyping, rigorous testing and user feedback, I’m excited to say that the Free2Go rack system is ready to launch. Now I just need your help to take it that extra mile and get the first production run (500 units) out to market.

The journey, from idea to reality, in a nutshell.

Where The Money Will Go

Should this dream be fortunate to meet its funding goal, the money will go toward the following activities:   

-First manufacturing run of Free2Go racks

-Packaging

Thank you so much for all your support and I hope to see you on the road and on the trail real soon.

Risks and challenges Learn about accountability on Kickstarter

We have worked diligently on our sourcing of components, identification of manufacturers, working with skilled engineers, etc.. to make Free2Go what it is today. As mentioned above it has been a long and thoughtful process that allowed us to arrive at this point. On the assumption that our campaign will be successful we have already produced and inventoried in Kent, 1000 T6 aluminum rods, 1000 tension joint knobs and identified the sourcing for the strapping system. We simply need your help in getting over the final hump to bring this idea to reality.
Thank you,
The Free2Go team
