BMW has been making bikes for years, but it wasn't until this week that we took the time to pedal around in one. After all, it's pretty clear that four wheels are more fun than two when it comes to the roundel. But, well, maybe not always. For example, if you're trying to navigate through a dense urban center, then a car often falls short compared to a bike if you're looking to, you know, actually get where you're going. We'd certainly rather get some exercise as we run our downtown errands than
Hey, it may not be the coolest looking thing in the world, but the newfangled Rubbee electric-bike kit will get you across town without pedaling. Or at least, some towns. UK-based Rubbee is looking to raise funds via Kickstarter to expand production for a roller-like contraption that may be attached to any bike and kick its electric-only speed up to as fast as 16 miles per hour.
Polaris is traditionally known as a powersports manufacturer, selling a range of ATVs and snowmobiles. Lately, however, the North Star brand has begun to move into the electric vehicle space. They now own neighborhood electric vehicle maker GEM, and have also made a significant investment in Brammo. And now, its extended its empire into the realm of electric bicycles.
Notice anything strange about the bike in the picture? The bright red hub isn't exactly subtle, but it does hide some impressive tech. Called the Copenhagen Wheel, this is a device developed by the SENSEable City Lab at MIT that basically can turn a normal bike into a connected electric bicycle simply by replacing your standard rear wheel with this one. The Wheel then adds regenerative braking, batteries, general packet radio service (GPRS), and a motor to your ride. There are also sensors to de
Bicycles can be a great way to reduce fuel consumption. They are efficient, relatively inexpensive, easy to store and care for and are often a fun way to score a little exercise while also getting you where you need to go. Of course, it's not always practical to pedal, which is one big reason that electric bikes are gaining in popularity so quickly.
Yamaha certainly has plenty of experience making sporty two-wheeled vehicles, as riders of the firm's R6 and R1 sportbikes can certainly attest. Now, though, it seems that the Tuning Fork company has decided to branch out into human power, specifically with a new hybrid bicycle. What makes this particular machine, knows as the PAS Brace, particularly interesting is how it manages the electrical assistance. First, an eight speed rear hub is used and allows shifting at any time, even from a dead s
We've gazed at OHM's line of electric bikes already this year, and now we find a review by an automotive writer for The Wall Street Journal. David Patton tested the entry-level machine from the company, known as the XU450. The 450 stands for Watts, which the electric motor is able to deliver for short bursts. The rear hub-mounted motor can sustain a constant 250 Watts and the lithium battery is good for up to seventy miles, depending on how much pedaling the rider is willing to endure. Interesti
India, the seventh largest but second most populous country in the world, has good reason to encourage electric vehicle sales, considering that its automobile market is growing very rapidly. Pollution could become a much larger problem than it already is if steps are not taken to manage it now. India's government realizes this fact, which led it to recently waive the excise duty for electric cars. Up until now, though, the tax has stood at 8 percent for electric bikes. Not anymore, as both two-
Let me get this fact off my chest before I write anything else: this thing is flippin' expensive! Alright, now that we're through with that, let's analyze this electric bike, known as Pi. The frame is an aluminum monocoque, meaning that it is a single piece made up of metal which is all a similar thickness. Moving on to the electrics, the batteries are nickel metal hydride, not the better-but-pricier lithium ion. The motor is a 36-volt brushless DC model which produces about 1 horsepower, or 750
