Sada Bike Folds into Size of an Umbrella

Folding Sada BikeWe’ve seen quite a few folding bikes over the years but none quite like the Sada Bike. The unique part of the design here is that the wheels are hubless, having no center sprocket and no spokes. The bike folds with one motion and the wheels come away from the frame completely.

Anyone that has done some bike riding might question the loss of leverage through gears on a center sprocket, and anyone that is a little bit of a heavier rider might also quickly note that the wheels without spokes might not hold a person. But, Sada really seems to be targeting more of a compact city bike that won’t be setting speed records or taking on any significant air. The bike (without the wheels) folds roughly into the size of any umbrella and can be packed into a rolling case or backpack.

Unfortunately we can’t try one out quite yet since the Sada Bike is still a prototype looking for some funding, but you can check out the video below to see what you think.

Boot Bag Is a Stylish Trunk for Your Bike

The Boot Bag in rich Argentinian leather

Problem: You want a bag that will also fit on your bike, but all bike-mounting bags are ugly. Solution: Hebie’s Boot Bag.

The Boot Bag is semi-stiff, open-top shopping bag for your bike. With a wide shoulder strap, you can carry it around the market as you shop. Then, back at the bike, it clips directly to the top of a front or rear luggage rack, ready to roll.

The Boot Bag comes in plastic or leather, and the lop-sided shape means that it stays away from either your butt (rear rack) or your various gear and brake cables (front rack). I’m not quite sure where the name comes from, but my guess is that it’s named after a car “boot”, which is the UK English word for “trunk.” That Hebie is a German company suggests that it could also mean “boat,” but I doubt it.

The price difference between leather and plastic bags is almost comically huge. The multi-colored plastic Boots go for around €28 ($39), and the “handmade Argentinian leather” version costs €260, or $360. You’ll also need an adapter for your carrier (Hebie or universal) for another €15 ($21) and a shoulder strap, for €11 ($15).

The Boot Bag is available now.

The Detonator brings electric biking to bots, looks pretty bomb

Parker Brothers Choppers, responsible for one of several Tron Light Cycle replicas seen recently, is continuing to prove that electric bikes aren’t all weedy-looking augmented pedal-powered affairs. This time, it tackled the Detonator concept created by Daniel Simon, a former VW designer who was also in charge of vehicle design for the Tron remake. Wired reports that the $100,000 bike charges in an hour and has an estimated range of around 80-100 miles on a full battery. According to the operations manager at Parker Brothers Choppers, it’s “not the easiest bike to ride,” though that could have something to do with Simon’s original design, geared for non-human droids able to rotate their legs all the way around. Human riders, on the other hand, would likely face some chafing issues.

Cute Japanese Robot Rides Bike, Plans Human Conquest

Two arms, two legs, two wheels and one diabolical, merciless robot brain

It would seem that putting a robot onto a bike would be a pointless exercise akin to putting gas-powered horses before a carriage. But the impracticalities of this little Japanese bike-bots are easily outweighed by its charm.

Lest you think that this is just a remote controlled bike with a dummy perched on top, watch until the 45-second mark. Here you’ll see the little fellow take his hand off the bars to wave, and put both feet down on the floor.

The robot is called PRIMER-V2, and was built by Dr. Guero of the website AI & Robot. He pedals to move forwards, and he balances like a human rider, by turning into any falls. The balance in this case is provided by a PID (proportional integral derivative) controller which uses feedback loops to adjust for error.

However the PRIMER manages to stay upright, Dr. Guero has given us a valuable insight into how the robot apocalypse will inevitably unfold. It will come from Japan, and it will come — unstoppably — on two wheels.

Pioneer’s Bike GPS Costs More Than Your Phone, Does Much Less

Contrary to the promise of its name, Pioneer’s Potternavi will not help you find platform 9 3⁄4

What sits on the handlebars of your bike, has GPS, an accelerometer, and LCD screen and ten hours of battery life? Nope, it’s not your smartphone — it’s the Potternavi, a specialized bike GPS from Pioneer.

The trouble is, it’s worse than your phone in almost every way. If we ignore the fact that you can’t do anything with it other than navigation and bike computering, and it still looks bad. The display is a tiny 2.4 inches, with 240 x 320 resolution, and the battery life isn’t much better than you get from a phone. Worse, when it launches in Japan next February, it’ll cost over $500.

On the plus side, it has built-in ANT+ support for hooking up wirelessly to cadence and power meters, and the price includes two years of cellular network access.

But the best part is the name, Potternavi. It’s not, as you would be forgiven for thinking, a device to navigate the Harry Potter universe. The name comes from the activity of “pottering,” or “puttering” as you call it across the pond. Who can’t love a device devoted to “occupying oneself in a desultory but pleasant way”?

‘Track’ Bike With Coaster-Brake Actually Looks Like Fun

SE Bikes’ Draft Coaster offers fixed-gear style with beach-cruiser control

The coaster brake, found on beach cruisers and Dutch-style city bikes, has come to the track bike in the form of the Draft Coaster from SE bikes.

Or should I say “track bike style“? For the Draft Coaster is anything but track ready. It is heavy (26 pounds or 12 kilos), has a hi-ten steel frame and comes with a riser bar, not drops. But no matter, as this is really about having a simple, clean looking bike to get around town.

When thought about like this, the design makes more sense. There are no visible brakes, and no cables, but there are fender mounts and platform pedals (or “peddles” as it says in the product blurb). The crankset is steel, the seat has a built-in bottle opener, and with the coaster brake you just push back on the pedals to stop.

At just $330, it’s hard to argue with this as a cheap beater for city riding. And despite that hi-ten frame, its still a lot lighter than a fully-specced commuter bike.

Quickfix Emergency Bike Fenders

Where I live, it doesn’t rain much, so you can get away running a bike without fenders, or mudguards. When it does rain here in my part of Spain, though, the heavens open and you can get a day or two of torrential storms.

Most people would just stay in, but where’s the fun in that? And that’s where Full Windsor’s Quickfix and FoldnFix fenders come in. Both of these are quick and easily mounted, and fold flat to fit in a bag. The FoldnFix attaches using cable ties, but the Quickfix is much more interesting.

The Quickfix is an origami-like fender which starts out flat and then folds to fit through the seat stays and stay stiff. Once in place, it is secured by press studs, and can therefore be removed easily when you’re done.

Fittingly, the company is based in London, the capital of rainy England (although not the rain capital of England, which is arguably Manchester).

If you ride a lot in the rain, you should probably use full fenders with mud flaps. Not only will they keep you dry, they’ll protect the bike’s drivetrain and headset from filthy, gritty road spray.

Full Windsor is in negotiations right now to find resellers, and should be available soon.

Bike Bottle Lock Trades Security for Convenience

Who needs water? The Bottle Lock puts a cable in your cage.

Carrying junk in your bike’s water bottle cage instead of filling it with delicious cool, refreshing water is probably as old as the bottle cage itself. Tools, keys and snacks can all be stowed either on an actual water bottle, or a water-bottle sized container. Now, you can so the same with a lock.

The Bottle Lock comes from rack makers Küat, and slides snugly into a standard cage. Inside, coiled like a low-security steel snake is a five-foot long, 8mm-thick cable (1/3 inch). Borrowing design cues from vacuum cleaner power cords, the cable unwinds to wrap around the nearest immovable street furniture before plugging back into itself.

A small compartment underneath opens up for stowing keys and other small items.

For anything longer than popping into a convenience store, you might want a stronger lock

It’s ingenious, and handy if you live in a very low-crime area. If your only worry about bike thieves is that the local yahoos might spot your ride and use it to get home drunk on a Saturday night, it’ll be fine. In a city, you may as well just leave the keys in the lock.

The Bottle Lock comes in black, white and pink. It costs $34, and will ship November 1st.

Kickstand Desk Lets You Ride Your Bike at Work

With the Kickstand desk, you can commute to work, even if you work at home

It might not offer the simple good looks of the Pit-In, the drive-in desk for bikes we saw back in March, but the Kickstand desk is both more practical (it has a bigger top) and more available (you can actually buy one).

The Kickstand desk caters to those obsessive multi-taskers who want to exercise and work at the same time. Less goofy than a treadmill desk, the Kickstand is tall enough to fit your bike underneath, and sturdy enough that it won’t wobble as you pedal.

Why not just use a regular stand-up desk, you ask? Because the Kickstand has a sliding top to let you reach the handlebars or change gears. Then again, the Kickstand starts at $2,500 ($2,750 is you choose a glass top over the standard wood), so you might not mind losing a little convenience to save money.

I’d skip it altogether. My current setup of a bar stool and an ironing board might not be ideal — my back aches and I can’t feel my fingers anymore — but if I had $2,500 I’d be spending it on a bike and actually taking it outdoors.

Day Bag Made from Recycled Car Airbags

The Day Bag is made from old, popped car airbags

After you crash your car, but before you decide you’d be better off getting around by bike, you might consider ripping out the now-spent airbags and making them into a tough and light duffel bag.

Or you could skip the whole crashing business altogether (although you should still ditch the car) and just buy one of E13’s SRS Day Bags.

The bags are made from “upcycled” airbags which have popped their last. The resulting Day Bag looks like a skinny duffel, and has a detachable shoulder strap which gets its own pocket to stow it when you don’t need it. In fact, pretty much every part comes from a dead car: The outer layer is a driver-side airbag, the lining is from the passenger-side bag, and the handle and strap are recycled seat belts.

Capacity is six liters, the length 17.5 inches and the diameter 6.25 inches. There’s also an 8 x 5-inch pocket inside.

For a recycled bag, it’s pricey at $120, but then again, think about what you’re now saving on gas since you swapped your car for a bike.
