Terrifying Cheetah-Inspired ‘Bicycle’

guepardo-vehicle

This is the Pardo, a concept human powered vehicle. Kind of cool looking, right? Like a big pedal-powered go-kart. Now take a look at this picture:

guepardo-vehicle-howto

Less cool, and much more scary. The Pardo (short for guepardo, Spanish for cheetah) splays the rider out prone on its plywood surface where he can cling to the small handle and start to pray for survival. Those pedals at the back are used in concert, you pump them together like a frog pumping his legs to jump, and this sends you flying forwards, face-first into oblivion. As for steering, a good deal of luck (and perhaps leaning) appears to be involved. The body of the cheetah folds in two, so it can be safely tucked in the basement when you are done terrifying yourself.

Not content with cool-looking renders of his design, Argentinian Pablo Lopez actually built a working prototype. It actually looks like a lot of fun, and it’s certainly a great antidote to beardo-recumbents. As you may have guessed, this is unavailable to buy, but it seems that money-making isn’t Lopez’ aim. “My main goal is transmitting and creating sensations”, he says.

Grace: An Electric Motorcycle Disguised as a Bike

grace

Let’s get one thing straight: Grace is not an electric bicycle. Grace is, instead, the “world’s first legal street E-motorbike.” But whatever it is, its fast.

The Li-ion battery powered bike can hit 45km/h (28mph), powered by a 1.3KW motor (this is actually limited by law — some hacking will get you up to 65km/h, or 40mph), and it will run for an average of 25 miles before needing a recharge. To stop you again, the stiff aluminum bike is equipped with disk brakes front and rear.

But where are these extra parts? The batteries are actually inside the frame, and the engine inside the rear hub, hooked directly to the axle (you can pick one of two motors, one for speeding on the flats and one for powering you up hills). This stealthy appearance is essential to the Grace being called an E-motorbike. Why? The blurb:

E-motorbikes can go as fast as e-scooters or smaller e-motorcycles, but in contrast to these two categories they are much smaller and lighter and can be taken into trains, cars or even aircraft without a bigger effort.

That’s the trick: You can tear around town at the speed of a small scooter (or at least at the speed limit) and at the same time ride on the sidewalk, sneak through red lights and park anywhere you like. That will seem like a great idea to some, and a terrible idea to others (like me). The barrier to entry is thankfully set pretty high, though: the Grace, hand-built in Berlin, will cost you €5877, or a few dollars short of $8,800. That’s enough to buy a scooter and a pushbike, with money left over, although unlike a moped it will only cost $1.40 per 100 miles to run.

I certainly don’t want to buy one, but I’d love to take one out for a spin.

Eastside Fixed: Low-Priced Frankenbike

eastside fixed

The first thing you’ll say about the Eastside Fixed from Campus Cruisers is “Wow, an aluminum fixed-gear for just $300!” The next thing you’ll shout is “Wait, how did they make an aluminum fixed-gear weigh 21 pounds?”

It’s true, 21 pounds isn’t heavy, but fixed-gear bikes don’t have much to add weight other than the frame and wheels, so even a steel framed bike (the usual fixed choice) can come in at less. Things get odder from there on. The $300 price is good only for the first 50 sold, after that rising 50% to $450.

And then there is the design. From the blurb: “Inspired by my days as a bike messenger in NYC, the Eastside Fix is the real deal.” Indeed. It has only a front brake, but the wheels both come with a brushed braking surface, the flat strip where the brake-shoes go to work. The frame has track-ends, the bits on the back that accept the rear wheel axle, but that seat-post lays back at a rather leisurely angle for a track frame.

It does look cool, though, and a flat bar can be way more comfortable around town than a drop-bar without brake hoods to lean on. It also has double walled rims and a flip-flop fixed/free hub. But I already bought one cheap ready-made fixed, and it was a dog. Fine for tootling around town, and for posing in the local plaza, but that’s about all. So, instead, dust off an old frame, throw a flip-flop wheel on the back and throw out all the extraneous hardware. It’ll cost you way less than even $300, and you’ll have a bike that should last you forever.

Danger: Bike Pedal Straps with Metal Spikes

stud-straps

Say what you like about fixed-gear freestyle (actually, I will: buy a frickin’ BMX), it has certainly made for some cool-looking bike products. Here is a spectacularly misguided but still awesome foot-strap design, a custom build from the Japanese bike bag makers Crank.

We suppose it was inevitable that, in a world of cycling gloves with the words “love” and “hate” printed on the fingers, we’d eventually see some punky, studded black vinyl bikewear. What next? Serrated brake levers? Price and availability unannounced.

Ikea Hack: DIY, Double-Decker Bike Rack

ikea-bikerack_01

If there was an opposite to “hemorrhaging”, that’s what I’m doing with bikes. The recent addition of a fixed-gear beater to the “stable” is testing the Lady’s patience and causing house-guests some painful collisions on their night visits to the bathroom. I need an intervention.

Or a home-made, double-decker bike rack, just like the professional looking Ikea-hack seen here. This simple bike-hanger consists of a powder-coated, aluminum Stolmen post ($30), a couple of brackets, some square-section tubing and a some hooks. The post stretches between floor and ceiling like a vertical shower-curtain pole and the two brackets are clamped on and used to mount the hooks. A half-hour job that comes in at around $40.

I’d be all over this for the apartment, but I don’t actually think it is the growing family of bikes that is the problem — it’s the tools in the kitchen and the oily hands I take to bed with me.

Cyclehoop Turns Every Street-Sign Into a Bike Rack

cyclehoops

Here’s a genuinely good idea for bike parking, which is currently, and surprisingly, being trialled in London.

The Cyclehoop is a steel hoop which clamps onto lampposts, street signs and other urban poles and turns them into proper bike racks. The advantages to the host city are great: it’s a lot cheaper and quicker than the digging and re-concreting required for normal racks, and the Cyclehoop takes up almost no space in comparison.

And its good for cyclists, too. The ‘hoop is put purposely low on the post to discourage top-tube-only locking, which is apparently a major encouragement to thieves. It also allows more than one bike to lock to a single post much more easily and stops them being lifted over the top. The units are secured using shear-bolts, which are bolts which lose their wrench-shaped heads at a specific torque, leaving behind a smooth, conical head that cannot be turned.

But there is one more advantage to the Cyclehoop — it legitimizes locking bikes up to street furniture, something most cyclists do anyway. Here in Barcelona, the law somewhat fuzzily says that you can’t lock bikes to lampposts or trees. This is so widely ignored that the cops let it go, usually, but of course that doesn’t stop the occasional old lady ticking you off.

The CylceHoop is being trialled in the Islington and Southwark boroughs of London. Any Londoners who have seen or used these brightly colored froot-loops locks, let us know what you think of them.

Flawed Bike Concept for Danger-Loving Hipsters

inner-city-bike

It’s hard to imagine a bike less comfortable than this concept design, but it does at least look cool.

The “Inner City Bike” was inspired by the cafe racer (check out those handlebars) and the roll-along hobby horse. The most obvious design feature is the lack of a chain. Instead, the crank and pedals are fixed directly to the rear wheel, meaning that the poor rider will be always leaning forward putting his weight on both his hands and his crotch — not ideal.

Further, the compact design puts the wheels very close together. This should mean tight turns are possible, but when combined with the weight-forward stance and the rather effective-looking front disk-brake, it looks like a recipe for over-the-handlebar disaster. And while the cafe-racer handlebars certainly look cool, putting them down low only makes this imbalance worse. Not that you’d be able to get up much speed anyway — those cranks look distressingly short compared to the big wheels they have to drive without any gearing.

One last point. Without the support of a down-tube, seat-tube or even a rear chain-stay, those two joints are going to be taking a hell of a lot of stress. It’s a good thing that the Inner City Bike is designed from non-riding urban hipsters, and therefore “more about fashion and culture than speed and performance.”

Hot-Seat: Anatomic Leather Saddles In Bright, Bright Colors

atomic-saddle

Yesterday’s post on the venerable Brooks saddle brought a few good comments (and one from somebody who appears not to have actually read the article). The most interesting pointed us to a seat from Selle An-Atomica, a Californian company (unrelated to Selle Italia) that makes leather bike saddles.

The product, the Titanico LD Watershed, is similar to the Brooks B17 in that it is made from leather strung between metal rails, only it has an anatomical cutout to ease perineal pressure. Brooks makes the B17 Imperial, which has a similar hole, but its perineal hole is smaller. The other big difference is that, being from sunny Fairfield, California instead of the rainy gray Midlands of England, the Titanico comes in colors! Alongside the more usual brown and black you can choose pink, white, red and yellow.

The leather is also said to be more flexible than that of the Brooks, and the shape is certainly more rounded. I’m very interested, not least by the opportunity for color-matching seat to bike. The catch is that the seats cost $180, but they do ship internationally. And even if you don’t want one, check the website. It’s not pretty, but it has a lot of great, in depth information about bike saddles and their design.

Gadget Lab FAQ: Six Things You Should Know About Brooks Saddles

brooks-1

It would be a little odd to review a product that has been around for 110 years, so we won’t. I have noticed, though, that whenever I stop and talk to other cyclists, they almost always ask about my Brooks Saddle, especially the few-months-old B17 I have on my fixed-gear bike (my other city-bike came with a twenty-something year old Brooks already attached). These English Bicycle saddles, hand made by the recently-independent company (it was owned by Raleigh Bikes since 1962) are both feared and revered due to the high price tag and the old-school style. So instead of a review, I’ll answer the questions that come up most often about these legendary bike seats.

How much is it?

Expensive, if measured in money alone, and dirt-cheap if measured in value. My basic B-17, the springless leather and steel flagship model, is listed at $120 in the US, and that’s the cheap one. It is, however, the only seat you’ll ever need to buy. If looked after, it should last longer than you, which makes it much more of a bargain than dropping $30 a year on some cheap plastic junk.

How long does it take to break in?

It depends. This particular B17 is the “standard”, and therefore has the hardest leather (there are pre-aged versions but the treatment makes the leather weaker). For me, it was comfortable from the moment I mounted it, although it took a few weeks of hard riding to get the thing to start changing shape. The ‘sit bones’ eventually make depressions in the seat, keeping your butt in place and making the seat feel softer, even though it isn’t.

Others report breaking-in periods of several hundred miles, and there is a magic lotion available from Brooks which can be applied to help soften the leather quicker. But don’t bother. The seats, even the ones without springs, are comfy from day one.

It’s very hard. Is it comfortable?

Surprisingly, it is comfortable because it is so hard. Instead of filling all your crevices with gel pads, which effectively give many more points of friction and cause saddle sores, the Brooks saddles are effectively a very stiff hammock hung from each end. This provides a measure of shock absorbance, and as your rear-end really only presses at the two pressure points on your sit bones (where the pelvis touches the saddle), there is no rubbing. The shiny surface, too, helps stop chafing and even heavy cotton jeans have moisture wicked-away quickly by the leather.

In short, it might look uncomfortable, but it is in fact the most comfortable kind of seat you can buy. Don’t believe me? Here’s what Sheldon Brown had to say:

Plastic saddles have four advantages over leather ones:

They are lighter.

They are weatherproof.

They do not require breaking in.

They are cheaper.

Leather saddles have only one advantage over plastic, but it is a big one:

They are much more comfortable!

Why is it pointed up at the front?

Because you sit on the back, wide part of the seat, and that section is at an angle to the nose, you need to tilt the seat back a little farther than usual. If not, you’ll slide forward onto the nose and put pressure onto the soft tissues of what my brother calls the “biffing skin”. Tipping it up makes the rear section flat enough to sit on comfortably.

Did that (saddlebag) come with it?

No, and it cost another $100. It’s an expensive D-Shaped Tool Bag, but like the seat, I expect it to last forever. That and it looks good and holds my toolkit without reminding me it is there by swinging around under the saddle.

Aren’t there other brands that are just as good?

Perhaps. Once upon a time, all bike seats looked like this, but today Brooks is about the only brand that is easy to find new in pretty much any bike shop.

Anything else? I’m sure some of you use Brooks saddles, and love them or hate them. And I know for certain that our cyclist readers are our most vocal readers. Let us know what you think.

Pump Up Your Bike Lights

puyl

Look! No, not at those hideous, atrophied monstrosities pretending to be handlebars. Look instead at that mini pump, the PUYL, which contains copper coil, a battery and an LED light. When you pump your tires, you charge the battery. It also solves the problem of where you should put your pump — in a pocket or hidden somewhere down near the bottle cage? No, it goes proudly on the top tube, shining for all to see.

It is a rather clever idea, marred by the fact that unless you ride across a river of broken glass and nails every morning you’re unlikely to keep the battery topped off enough to use it daily — even maintaining high-pressure tires in their almost rigid state requires no more than a few stiff strokes. However, as it is a patent pending design (which won designer Kai Malte Roever an award at Eurobike this year) you’re unlikely to find many people using one. Thus you can leverage their curiosity and let them give the shaft a few sharp tugs to keep the batteries full.
