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.
