Computer Scientists Build Wireless Bike Brake. What Could Possibly Go Wrong?

Holger Hermanns crouches proudly beside his proof-of-concept wireless-braking bike

Computer scientists at Germany’s Saarland University have worked long and hard to rid your bike of that pesky one foot of brake cable which used to curve, short and graceful, down to the front wheel. Instead of a simple system of super-reliable levers and cables, the Saarland team uses a wireless transmitter to brake the bike.

The wireless brake consists of a transmitting hand grip and a motorized disk-brake caliper. Squeeze the grip and the brakes are actuated according to a radio signal. Squeeze harder and you brake harder — as long as your batteries are charged. Just watch out for pranksters with RF transmitters who trigger your brakes from afar.

The Saarland team’s work isn’t intended to actually be used on bikes. Instead it is an experiment to see if wireless brakes can ever be made safe enough for use in trains, planes and automobiles. If you’re testing things out, obviously a slow-moving bike is a safer environment than a landing airliner.

The boffins have managed to get reliability up to a rather decent 99.999999999997 percent, which is a lot better than the reliability of an urban hipster on a brakeless fixed gear bike with a loose-fitting (and skip-happy) chain. This is in part achieved by redundancy: several transmitters send duplicate signals, but even this was found to fail if configured incorrectly.

The system is still far from perfect, but the use of brake-by-wire tech could incorporate anti-lock tech, which could prevent disastrous front-wheel skids in the wet, for example.

I’ll be sticking with cables for the foreseeable future. The last thing I want is to be forced to walk home because I forgot to charge my brakes.

Adjustable Balance Bike for Fast-Growing Kids

The Strider ST-3 grows with your kid

Some people think that bikes are just for kids. Those people should be sterilized. But bikes are pretty great for kids, and the sooner you get them started, the sooner they’ll be riding without training wheels. Seriously. I know bike polo players whose kids were riding at three years old, which is pretty badass.

Which brings us to Strider’s new pedal-less balance bike, a two-wheeler which will carry toddlers from 18 months to three years. The ST-3 grows with your kid, with adjustable-height handlebar and saddle. Grown-up roadies will envy its 6.4-pound weight, and anyone can appreciate the polymer tires, which won’t ever go flat.

These things look like great fun, but there’s an even better way to save money. Just take the cranks and chain off a regular kids’ bike and put them back on again when little Johnny learns to balance.

The Strider ST-3 will be out for Christmas, and will cost $130. It is not yet on Strider’s site.

Trek Belleville Gets You Around in Style

The Belleville isn’t what you’d expect from Trek, but it’s pretty gorgeous anyway

This handsome machine is part of Trek’s 2012 lineup. It’s called the Belleville, and the bike itself is as elegant as the name when it comes to getting you and your stuff around the city.

The Belleville lands somewhere between an old-style tourer and a Dutch-style city bike, although the build itself is all modern. It has three speeds hidden inside the rear hub (Shimano Nexus), and a 6v dynamo inside the front one. Rider-friendly features include full-coverage fenders, dynamo-powered lights, a chain-guard and front-and-rear racks and a long-lasting (and very comfortable) steel frame.

In short, if you want to get around in comfort and style (but don’t need to carry the bike up five flights of stairs when you get home), this is designed for you.

The Belleville costs $720, which seems pretty good until you realize that many of the features are optional. Racks, fenders and lights will cost extra, but this price is also the MSRP, so you should check things out at your local bike shop when these start to turn up.

Bluetooth Inter-Bike Communicator for Cyclists

It might look blessedly cable free, but things could get messy, fast

Cyclist? Incorrigible gadget freak? Do you still — miraculously — have space on your handlebars to clamp one more widget? Then I have just the thing for you, you bearded freak, only you’re going to have to make some friends if you want to use it: The HIOD One cycling communicator.

The HIOD One is a Bluetooth communication setup for up to five cyclists, and it looks to be a real pain to use. The communication part looks great: you can talk to one person at a time, up to 400 meters (1,300 feet) away via Bluetooth (Bluetooth 4.0, presumably). You can also use it to listen to music, and to talk on the phone.

But then we get to the practicalities. First, and most sensibly, is the bar-mounted head unit with a high-contrast OLED display. This is the control center. Then, there’s a wireless voice unit, clipped to wrist or chest or even helmet. And by wireless I mean wireless until you plug in the mic and the earphone, which you’ll need to actually use it.

For some, this will kill the deal right away. A lot of people don’t like to ride with headphones for reasons of safety. For me, a single earpiece drives me crazy with its asymmetry.

If you manage your cables properly, though, this is a nice hi-tech alternative to walkie-talkies. On the other hand, for anything but ultra-lightly equipped road racing, you might as well just buy some cheap walkie talkies, right?

The HIOD will eventually go on sale when the company has managed to find some dealers to sell it.

E-Bike Cruiser With Trunk, Stereo, Style

Retro looks and modern gizmos won Tony Pereira the Oregon Manifest constructors prize for the second year running

Yeah, yeah, that idiot Charlie Sorrel is writing about yet another electric bike. But wait a second: this one is actually super-cool.

Not only does Tony Pereira’s bike look like something Pee-wee Herman would ride, it also won the Best in Show prize at this year’s Oregon Manifest Constructor’s Design Challenge.

Tony works out of Portland, OR (of course), and although he styles the bike after a fifties cruiser, it is totally modern. The “gas tank” is in fact a battery pack hooked up to a 350 watt Bionx electric hub in the rear wheel, and the carbon-fiber trunk up front is lockable and houses a sound system, perfect for annoying everyone on your next critical mass. The battery is good for 60 miles.

That trunk also has a small recess for a cellphone and cycle computer, and has USB ports for charging anything else.

The final touch is a U-lock integrated into the frame. From the key (which is inserted into the head-tube), it looks like he used a Kryptonite lock. This is the same integrated lock design that won Tony the prize last year.

You won’t be able to buy the bike (yet), but if you ask nicely, and have the right money, Pereira might just build you one.

Samsung ‘Fixie’ With Top-Tube Tablet Mount

Fixie Fashion: Samsung commissions ultimate Galaxy Tab dock

There’s some silly two-faced fashion going on over in London Town. Samsung, maker of me-too touch-screen devices, commissioned Brick Lane-based bike builder 14 Bike Co to make a bike and mount for its Galaxy Tab tablet.

In keeping with current fashions, the bicycle is a fixed gear model with obligatory Brooks saddle, and although it does actually have a pair of brakes, there are no cables or levers — kind of like a tablet that runs Flash, but doesn’t enable it by default. The bike is white on one side and black on the other, matching either Galaxy Tab colorway.

The tablet holder is fashioned from carbon fiber and dangles from a cylinder which grabs the top tube. Samsung says that this lets you flip up and use the Tab when on the bike, but it also means that the thing will flap from side to side whenever you turn a corner.

Ridiculous as this implementation is, tablet on a bike are actually a pretty good idea. The big screen and long, long battery life make the iPad a great handlebar HUD, GPS tracker and general mapping device. I currently tuck mine into a handlebar bag, but that means reaching in every time you need to use it. Better would be a proper handlebar mount.

I’m in the middle of building a touring bike (Surly Long Haul Trucker framer and Shimano Alfine 11 hub, as you’re asking) and I have a feeling that the iPad might neatly be stowed in the map-case attachment for the Ortlieb handlebar bag. Full report if that works out. In the meantime, ZooGue’s three-ring binder adapter for the iPad might let you replicate Samsung’s shenanigans yourself.

Brompton H-Type For Tall Riders

The longer tube below the hinge can be seen in the Brompton on the right

Six-footers looking to buy a folding bike will be pleased with the news that Brompton is set to launch a bigger version of its famous folder. The H Type shifts the handlebar up 60mm (2.4 inches) and out 13mm (a half inch). This might not sound like much, but bike comfort is a game of millimeters, so two inches is quite a lot.

The extra height is added not just by lengthening the steerer tube (it seems wrong to call it a stem) — which would cause the tips of the bars to hit the ground when folded — but also by adding distance between the hinge and the headset. This adds 100 grams to the weight of the bike (roughly 9-12 kilos or 20-26 pounds), and the bikes can still fit into all existing bags (the saddle is the high point when folded, not the bars).

Other tweaks to the line are grippier, easier to fold pedals and — going by the photos and past history at least — new colors. The price difference for new bikes is as yet unannounced, but your own bike can be retrofitted for a painful $400.

JamBox Designer Reinvents Neighborhood Biking

The ultimate JamBox mount: An entire bike

Yves Behar, the designer of JawBone’s JamBox speaker, has obviously heard that I’m looking for a JamBox bike mount. Only instead of just designing a mount, he’s gone and built a whole bike to hold the thing.

That’s not strictly true, of course. While the Local, as it is called, does indeed hold a JamBox, it is designed to do a whole lot more. The Local is “the bike version of the practical pick-up truck.” To this end it does everything other cargo trikes can do, and more.

The Local will carry luggage and kids on its low front platform, and with a strap it will even carry a surfboard. Lights are built into the frame, there’s a tether to stop anyone snatching your bag off the front shelf and the bike features the first integrated lock that looks like it would work.

The D part of a d-lock is integrated into the frame at the front, and a bar locks across its ends. Remove the cylinder, drive the bike so its front swallows a pole and re-lock. You’re done.

Finally, a Shimano Alfine 11 hub and disk brakes front and rear will start and stop you easily.

The idea is that you can use this bike to do anything a car could do in your neighborhood. I like it a lot, and especially the light, bright colors that make it less like the serious cargo-carriers my local fruit shop uses to deliver its goods.

Behar makes no mention of price or availability, but if any concept deserves to make it into the real world then this is it.

Full-Sized Electric Scooter Legal in Bike Lanes

The FlyKly electric scooter, coming to a bike lane near you

What would you say if I told you that the scooter you see above will soon be shooting around your town or city, nipping in and out of bike lanes, piloted by untrained, unlicensed drivers? If it makes you angry, prepare to get angrier still, because what I just told you is the truth.

The scooter, called the FlyKly, is a rechargeable electric motorbike with vestigial pedals. Because it can reach just 20mph and has a motor of less than 750W, it qualifies under Federal electric bicycle law as a pushbike. 20mph (or 32km/h) isn’t fast enough to ride in traffic, but is fast enough to be a danger to cyclists.

The FlyKly comes in two models, both costing $1,900. The “Modern” looks like a regular gas scooter, and the “Vintage” has less fairing and more chrome. Both weigh 125 pounds (57kg), both have a range of 40 miles on a charge, and both will carry 500 pounds (227kg).

The Modern has disk brake at the rear (for effortlessly skidding out of control) and drum brake at the front. The Vintage has a pair of drums.

The FlyKly folks claim that, at five cents per charge, you can go 1,000 miles for a dollar. To charge, just plug the bike into the charger, or lug the battery pack inside and hook it up for 4-5 hours.

If it could go a little faster, it would be just about perfect, would require training and a license to use, and would be kept out of bike lines. As it is, it just looks annoying and dangerous: Consider that, here in Spain, it is legal for bikes to ride on the sidewalk.

On the other hand, it’s way better than a car.

The Modern is available for pre-order (ships October) and the Vintage can be had now through UrbanDaddy through some tedious membership program.

Beautiful Bouncing Bike With Sprung Steel Wheels

Boing boing! Ron Arad’s steel-wheeled bike is totally rideable

If you were to idly doodle a picture bike whilst chatting on the telephone, you might slip from realism into fanciful embellishment. And if your were placed on hold during that call, or if you’d smoked a little something before it, you might come up with something like Ron Arad’s WOW Bike.

Arad’s design is like a fixed-gear 29er rendered coming via your grandmother’s wallpaper. Everything about it is familiar except for those wheels, each fashioned from 18 strips of steel. These strips are bent and pinned to make a kind of chromed chrysanthemum.

The bike was designed for the fancy W hotel chain, and can be ridden by any guest brave enough to do so. Currently the bike is in the Leicester Square branch in London. So how does it ride?

Surprisingly well, says Arad’s design director Marcus Hearst. And he means “surprising” — the design was put together in just two weeks, with no testing, and no real idea of whether the wheels of steel would even work. The result is a softer ride than you’d get on regular wheels, but still quite practical.

The bike will be at the London W until October 29th, after which it will be auctioned. Any Gadget Lab readers who take it for a spin on London’s rain-slicked streets and live to tell the tale should tell us about it in the comments, or just e-mail me direct from your hospital bed.
