Sanyo today unveiled the Eneloop electric hybrid bike [JP], which will be on sale in Japan in early February 2009. The company is following Toshiba, Yamaha (Yamaha even sells two bikes) and Panasonic with their new addition to its Eneloop series of particularly “green” electronic products.

The bike is powered by a rechargeable lithium-ion battery and harnesses energy from braking when the bike goes downhill while being able to double the rider’s pedal force when going uphill through powering the front wheel. Sanyo claims their bike can travel 1.8 times faster than non-electric bikes.

Yamaha started selling a lithium-ion battery-powered electric bike in Japan in August (Panasonic followed up with its Vivi RX 10-S soon thereafter) and now presents the PAS CITY-C [JP].

The new Yamaha bike, which was manufactured in cooperation with Tokyo-based design company Plus Minus Zero, bike will be Japan-only.

Know what’s great about owning a home? Nothing. Just ask me, I used to own one. In retrospect, I should have just bought a gigantic hole and a cheap shovel and set aside a weekend to scoop five years worth of my money in there.

Anyhoo, one of my least favorite things to do as a homeowner was mow the grass (a close second after shoveling). While this Mowercycle certainly would have eased the pain somewhat, it would have added another element to mowing the lawn; biking. And believe it or not, I don’t like riding bikes anymore. That stopped when I turned 16.

But hats off to you, inventor of the Mowercycle – whoever you are. You’ve given us all a little hope. Plus, this Mowercycle doesn’t look all that difficult to build. The front wheel of a bike doesn’t do much and those push mowers come apart at the base – you’d really just have to figure out how to connect the two together.

Last week Panasonic presented [JP] a new electric bicycle to be released on the Japanese market on August 20. The so-called Vivi RX 10-S will cost $1,400. Panasonic hasn’t said yet whether they will bring the bicycle to overseas markets as well.

The bike’s main feature is a braking system that can recharge a 10Ah Li-ion secondary battery, which weighs 2.5kg, has a rated voltage of 26 V and is located next to the rear wheel. Every time the owner brakes, a mini motor mounted on the front wheel generates power. According to Panasonic, charging the battery via this method alone proves to be almost impossible however. The recharging system fails when riding faster than 24km/h.

Panasonic says in internal experiments, the regenerative braking system extended the assisted travel range from 90km to 125km when riding in normal mode. Using the bike’s automatic mode, the maximum distance owners will be able to cover is 182km.

The so-called Vivi RX 10-S comes with an aluminum-made frame and weighs 25.7kg. The company says it aims at selling a total of 3,000 bicycles in the first year.
