Australian company Stealth makes the kind of electric bicycles everyone would love to make if there were no government-imposed 200-watt power restrictions pooping the party. Packing 4.8 kW of peak power and with a top speed in excess of 80 km/h (~50 mph), the original Stealth Bomber is a far cry from your urban commuter – it's one wild ride. Watch Gizmag's Editor Noel McKeegan and a couple of slightly unhinged buddies put this electric powerhouse through its paces in our video review.
There's a certain irony to most e-bikes. Their motors and batteries make
them easier to pedal, yet those same components also make them much
heavier than regular bikes – weights of 50 to 60 lb (23 to 27 kg) aren't
uncommon. Additionally, some "bike snobs" think they're kind of
dorky-looking. E-bike enthusiast Troy Rank and his team, however, have
set out to address the weight and appearance issues. His Maxwell EP0
looks almost entirely like a regular steel-framed flat-bar road bike,
and it's claimed to weigh as little as 25 lb (11 kg) depending on the
When Spanish motorcycle manufacturer Bultaco announced its return to the market last year, we were expecting some new electric motorbikes. What we weren't necessarily expecting was an electric bicycle. For the first product launched in its second life, Bultaco has shrunk its electric powertrain technology down and put it to asphalt and dirt in the form of a full-throttle electric-assist mountain bike: the Brinco e-bike.
If you'd like the ease of an electric bicycle but don't want to give up your perfectly good "manual" bike, there is something you can do – you can replace your bike's existing rear wheel with the electrically-powered Copenhagen Wheel or FlyKly, or replace its front wheel with the Omni Wheel. Those three products may soon have to make room for another competitor, however, as the Centinel Wheel enters the marketplace.
Although lithium-ion batteries perform far better than alkalines,
they're also relatively costly, the lithium salts used in them aren't
widely available, and they sometimes catch fire. That's why some
scientists are suggesting sodium-ion batteries as an alternative. To that end, Williams Advanced Engineering recently demonstrated that they could be used to power an electric bike.
While they come in various forms, handlebars are a vital component on virtually every type of bike. From the standard 10-speed, to the cargo hauler, to the lean-back recumbent, a bicycle's handlebars provide a simple means of steering and control. As the name suggests, the Joystick Bike replaces the ubiquitous bars with a right-hand joystick, delivering precise control that makes riding a bike a little more like flying an aircraft or playing a video game.
Within an increasingly crowded electric bicycle marketplace, it takes a
special something for an individual e-bike to stand out. The Mando Footloose
does so, however, in that it has neither a chain nor a belt drive – plus,
it folds. Mando has now announced a more affordable non-folding version
of the bike, known as the Footloose IM.
If you don't live in some place flat like the Netherlands and you're of a certain age, electric bicycles seem like a pretty good idea. Unfortunately, they also tend to be rather expensive, but the creators of the Wave eBike are looking to buck the trend. Billed as "the world's most affordable electric bike ever," it is claimed to provide long range and high speed at half the price of comparable models.
