French unveil 'world first' hydrogen-powered electric bike emitting only pure water

 

 

12:25PM BST 01 Oct 2015

The world’s first commercial electric bike running on hydrogen with only pure water as waste, so its makers claim, has been unveiled in France – and already snapped up by the country's post office.

It takes five minutes to charge and has a battery life of 100 kilometres (62 miles) and its Gallic makers claim it is a “world first”.

The Alpha bike, which hides its hydrogen batteries in its frame, leaves an almost neutral carbon footprint, its designers at Pragma Industries in Bidart, near Biarritz, southwestern France insist.

“The bike’s battery provides electricity from hydrogen and emits only pure water,” Pragma CEO Pierre Forté, 38, told AFP.

“This is a world first,” he said. A pit stop at special hydrogen recharge ranks only requires a five-minute charge compared to “three or four hours” for other types of electrically assisted bikes, he said.

Its autonomy of 100 kilometres is also higher than others. “All this with a minimal environmental footprint as these bikes are made of up ever more recyclable products," he said.

The charging stations themselves run on solar or wind power to cut carbon emissions as much as possible.

Other models exist but are for now only in the “prototype phase,” said Mr Forté. The French Post Office has reportedly expressed an interest in ordering a fleet.

Production will begin with 100 bikes in 2016, which will be ramped up to 1,000 by 2017. At this level of output, the cost of a bike will be around €2,300 £1,700) - no more expensive than existing top-bracket electric bikes.

Alpha will be officially unveiled to the public during this year’s Intelligent Transport Systems congress in Bordeaux.

A Bike Without the eXcess

 

Posted: 13 Aug 2015 12:00 AM PDT

The minimalist Connondale X-Bicycle concept earns its name for the extreme X-shaped frame that enhances its modern function and style. The monocoque carbon fiber frame can be divided into 4 sections with each extension serving to support the basics including seat, handlebars, wheels and gearing system. With a riding stance as aggressive as its aesthetic, its sure to intimidate if not challenge the competition.

Garmin gave hope to many a floundering tech startup's CEO earlier this year when it purchased Ikubu Ltd in the wake of a crowdfunding campaign that came up short. Though the company failed to capture the imagination of the Dragon Innovation crowdfunding community, Garmin liked the cut of Ikubu's jib, so it snapped the company up with a view to bringing its rear-facing bike radar system to market. Now, the electronics giant has unveiled the finished, more polished product dubbed Varia Radar, which also integrates with Garmin's Edge cycle computer.

In essence, the bike radar hasn't changed dramatically from the pre-production model we reviewed last year. The system consists of two modules, a tail light transmitter that attaches to the seatpost and a radar display unit that is mounted on the handlebars. When a vehicle approaches from behind, the rear-facing radar detects them at distances of up to 140 m (150 yards). This data is transmitted to the display unit with soon-to-be passing vehicles presented as a line of LEDs.

In the earlier model, the 40-lumen tail light begins to flash more rapidly the closer the approaching vehicle gets as a way to make the rider more visible to the driver. The updated model beams at only 15 lumens and retains this flashing feature, though the brightness of the LED scales up as the vehicle comes closer.

The Varia Radar can also be paired with Garmin's Edge cycling computer. This gives it the ability to detect up to eight approaching vehicles, giving an indication of how quickly they are approaching and also offering a threat level rating. Bundled together, the Varia tail light and radar display is priced at £240 (US$375).

The Semi-pro Luxury Bike

 

The Semi-pro Luxury Bike

Posted: 04 Jun 2015 09:34 AM PDT

As you might’ve guessed from the name, the Diamante’s cutting-edge frame takes inspiration from the precious stone. Not only a symbol of luxury, its shape is ideal for strength and even weight distribution. Despite its pristine aesthetic, it’s still a muscle-bike with 9-speed transmission and semi-pro front shocks. Minimal and sleek with an uber-lux look,  it’s the bike you might even want to valet!
