Ciclotte exercise bike for the big wheel enthusiast

by Nilay Patel, posted Apr 29th 2009 at 6:39PM

We can't say we've given much thought to the state of the exercise bike design, but we're definitely digging the Ciclotte concept that was just exhibited in Milan. Details are light, apart from a note that it's almost entirely made of carbon fiber, but hopefully designer Luca Schieppati is working on bringing it -- and that crazy road-faring version on the left -- to market soon. Hit the read link for way more pics.

Video: The Shimano Di2 electric bike shifter for the paradoxically lazy

by Thomas Ricker, posted Mar 17th 2009 at 5:45AM

If the idea of wrist-twist is too taxing, perhaps an electronic shifter is the best option to get your meat-bag mobile. With the press of a button, the Shimano Di2 derailleur on this $10,000 Merida Scultura 909 road-racer automatically eases you into that next gear. Now shipping on select bicycles, the Di2 system features a rechargeable Lithium Ion battery (lasting 1,000 kilometers or 621 miles) powering an integrated CPU that monitors and adjusts the front and rear derailleurs to keep them perfectly trimmed. The system allows you to shift 30% faster (as fast as you can move your finger) than with mechanical derailleurs -- even under load while cycling out of the saddle. Great for pros (we guess). For everyone else there's Vespa. Check the action after the break.

GreenWheel converts any Huffy 10-speed into an electric bicycle

by Darren Murph, posted Feb 26th 2009 at 7:13PM

It's a struggle we all face. There's the urge to bike to work each day, and then there's the realization that you're too huge / lazy / tired to make it on your own. Brilliant minds at MIT understand your frustration, and rather than asking you to drop a few grand on a bona fide electric bike, they're developing an apparatus that can convert any standard bicycle into one that's juiced. The GreenWheel contains an electric generator, batteries and an electric motor, all of which only need a wheel to be respoked in order to fit in. Under its current configuration, a single GreenWheel (yes, one can be added to each wheel) can propel a bike and your faineant derriere for around 25 miles; start peddling and that range doubles. There's no clear indication of when these things will splash down at your local bike shop, but word has it that Copenhagen and South Africa are already looking to add it to their public transportation systems by 2010.

Light Lane concept would protect cyclists, bring Tron to life

by Donald Melanson, posted Jan 16th 2009 at 11:03PM

Sadly, there doesn't seem to even be so much as a prototype of this one just yet, but we're certainly hoping that this so-called Light Lane dreamed up by Alex Tee and Evan Gant of Altitude sees the light of day sooner rather than later. The idea, as you can see above, is to project a bike lane wherever the cyclist travels, which would give drivers a clearer indication of where not to tread than a simple safety light or reflector is able to do. The key to the setup is, of course, frickin' lasers, though it seems you'd have to provide your own "zoooommmmm" sounds as you pedal around town.

Industrial design student builds Capella, the portable, unobtainable electric bike

by Joseph L. Flatley, posted Jan 3rd 2009 at 8:01AM

Where most students only go so far as to render their designs, Truong Minh Nhat -- working on his senior project at the Ho Chi Minh City School of Architecture -- made a functional prototype, sourcing the parts from local manufacturers. Dubbed Capella, the lightweight vehicle folds down to a neat "backpack sized" package (well, maybe a large backpack), travels over 30 miles an hour, has a range of about 7.5 miles (on a two hour charge), and in its final, mass produced form it should weigh about 22 pounds. If you're looking for a wilder ride than most electric bike designs offer, and you happen to be reading this in Ho Chi Minh City, keep your eyes peeled.

Update: This bike has a top speed of 30 km (roughly 18.6 miles) an hour.

Optibike's OB1 hybrid electric mountain bike: yours for a cool $13,000

by Joseph L. Flatley, posted Dec 2nd 2008 at 12:17AM

Sure, it won't stabilize itself, it doesn't sport a cute wicker basket, and it has a five figure price tag, but the 2009 Optibike OB1 is on sale now -- and if you're a typical Engadget reader, you're probably considering four or five of them for you and your family. Designed by award winning bike designer Jim Turner, this lithium-ion battery-powered hybrid features a GPS, fully integrated PDA (to keep track of the vehicle's performance), two hours of battery life, and -- for those of you who like to kick it old school -- pedals. You know, for pedaling. Be sure to order yours now -- only twenty-four OB1s will be manufactured this year.

Sanyo's eneloop hybrid bike has basket, will travel

by Tim Stevens, posted Dec 1st 2008 at 11:25AM

Looking for an electric bike that does the pedaling for you? You have plenty of choices, particularly if you're willing to drop over $2,000, but finding one that uses regenerative braking to extend the life of its meager on-board batteries isn't so easy. Panasonic's Vivi RX10S is about your only choice until February, when Sanyo's new eneloop-branded bike is set to start pulling weak (or just lazy) Japanese riders up up inclines before recharging itself on the way back down. On a hilly course a charge is said to last about 35 miles without braking, 46 by charging only when braking, and 62 miles in "auto" mode (charging on downhills, too). If you live in Japan it'll be yours for 136,290 yen, about $1,450 US -- but if you live around here we'd recommend not canceling your spinning class just yet, because while Sanyo pledges to ship this elsewhere in the world "at some point in the future," it could be awhile before this thing starts hitting the diamond lanes near you.

Intersection sensor activator puts an end to cyclist discrimination

by Samuel Axon, posted Nov 7th 2008 at 3:42PM

You're a good person with noble motivations -- you ride a bicycle instead of driving because it's healthy and it doesn't have a disastrously negative impact on the environment. We salute you, but not all of society appreciates your virtue like we do. In a sinister and systematic oppression of cyclists (we're absolutely certain it's intentional), many traffic lights are governed by sensors in the pavement that give a green light only after they've detected the change in inductance when a large metal car pulls up. Before you take up arms, though, take a look at this recently-patented device that sends out a signal that fools the sensors so cyclists don't have to wait for a car to unwittingly play good Samaritan -- we suppose we'll try this out just in case before we incite a violent revolution.

Self-stabilizing bike stabilizes bikers who can't stabilize themselves

by Joseph L. Flatley, posted Nov 4th 2008 at 3:27PM

The bicycle -- whether electric, rocket-powered or simply sporting Bluetooth -- is certainly looking a lot better these days, and now researchers at Yokohama's Keio University have devised a way to keep the vehicle upright without the help of a human operator. The otherwise typical bicycle sits on a set of rollers and is equipped with two motors: one moves the rear wheel an average of 2.5 meters (8.2 feet) per second while the other controls the handlebars. A linux controller keeps an eye things via webcam and gyro sensor, steering the vehicle and adjusting its speed as necessary. Currently the bike is only able to stay upright when moving in a straight line, but soon enough we should see a system that can take corners and work in real world situations. Because why should people with an adequate sense of balance have all the fun?

CY-FI Bluetooth sports speaker, tiny Sigourney Weaver co-star

by Thomas Ricker, posted Sep 10th 2008 at 7:02AM

CY-FI just unwrapped its latest wireless speaker system for your bike. The CY-FI Bluetooth wireless sport speaker weighs just 4-ounces, supports hands-free and stereo Bluetooth profiles, and works for about 5.5-hours on battery when clipped to your bike or pretty much anything else. But by attaching it to a bicycle, Cy-Fi can call it a world's first Bluetooth sport speaker, which is nice. Unfortunately, the September 22nd launch with a $180 price tag is not.

Powabyke X-6 reminds us just how boring we really are

by Paul Miller, posted Aug 19th 2008 at 11:15AM

We've got the Jack Johnson playlist locked and loaded, our polarized Oakleys are firmly ensconced, and those khakis are tucked snugly into our tube socks. It's time to ride, fool. The Powabyke X-6 is the electric bike for the bore in all of us, masquerading perfectly as a traditional road bike, complete with the old "battery disguised as a water bottle" trick. The six-speed electric bike weighs in at 48.5 pounds, with an battery-powered top speed of 15mph -- the max allowed by law -- and a 15 mile range. The battery can be detached and charged indoors, but replacements run a few hundred dollars, so don't lose sight of that sucker. The X-6 should be out in the UK this September for £750, about $1,395 US.

Ultra Motor intros A2B electric bike for urbanites

by Darren Murph, posted Aug 13th 2008 at 6:30PM

A clever name, a clever design and a solid premise -- now, if only we didn't see a set of front and rear pegs along with Dave Mirra grinding down a stairwell each time we looked at it, we could actually take this thing seriously. Unfortunately for our childish hopes, Ultra Motors' A2B electric bike actually won't be used in the next X-Games, but it may just get you to and from your downtown apartment. This comparatively small electric bike features a full suspension setup, an oversized seat and a battery arrangement that provides 20 miles of travel without a touch of the pedal. Also of note, riders can reach speeds of up to 20mph (or 50mph if traveling downhill, so we hear), and an optional secondary battery can double the aforesaid distance capability. Look for this one to hit authorized dealers next month for a presumably lofty amount of scratch.

Update: And we've got a price of $2,599. $2,675 with pegs, a splash guard and a few random stickers.

Bricycle electric tricycle actually cooler than it sounds

by Nilay Patel, posted Aug 2nd 2008 at 12:39AM

Compared to the almost universally-embarrassing homebuilt electric vehicles we've seen pop up so far, the Bricycle electric recumbent bike is up there with the Tesla Roadster in terms of sex appeal -- even though it kind of looks like a futuristic delivery truck. Designed to transport one person as efficiently as possible, the Bricyle (developed by someone named Brian -- clever) isn't completed yet, but it's got a 48-volt electric-assist motor for when you get tired of pedaling through the 21 bicycle gears, and disc brakes for quick stops. Sure, but can you get it in a color besides electric cucumber?

Yamaha's PAS Brace electric bike gets smart... maybe too smart

by Darren Murph, posted Aug 1st 2008 at 9:22AM

Look, we'll be the first to hand over an adequate amount of kudos each time artificial intelligence is improved, but we won't lie -- we're kind of scared about giving our vehicles too many smarts. Yamaha Motors has just unveiled a comparatively affordable electric bike which looks to continuously monitor your driving behavior and react accordingly. The PAS Brace features the highly touted S.P.E.C.8 mechanism, which keeps a close eye on your speed, acceleration and gear position in order to conserve battery life when possible and provide just the right amount of oomph to get you over that one... last... hill. This one is set to land in Japan on the same day the Olympics begin for ¥125,800 ($1,171), and if you're not feelin' the black, red and white flavors will be available for your pedaling pleasure.

$2,000 Giant Twist Freedom DX electric bicycle gets pedaled on video

by Darren Murph, posted Jul 23rd 2008 at 6:00PM

For those balking at the $2,000 price tag, you should really take a look at the competition before scrunching your nose up and walking away. That being said, two large is still a lot to drop on something that could still require at least some bodily exertion, but a recent video review over at Popular Mechanics could help you determine whether this particular bike is worth you while. The Giant Twist Freedom DX can roll up to 75 miles on a mixture of battery and human-powered pedaling, and the motor touts three different modes (Eco, Normal and Sport) to satisfy your mood / riding requirements. Nah, Ironman participants won't want anything to do with this heap, but those looking for a greener (and oftentimes quicker) way to commute in the city may find lots to love. The video, as promised, is waiting in the read link.
