Electric bikes are becoming an increasingly intriguing option for commuters who live relatively close to work or for avid outdoor enthusiasts. As battery and motor technology forges ahead, the speed and range of ebikes surges with it, as evidenced by the new Electric Motion Systems E+. Although DOT requirements force a road-going electric bike to twenty miles per hour, tops, the E+ is actually capable of thirty when traveling off the beaten path. With no pedaling at all, the E+ can manage twenty miles on a single charge of its 36 volt nickel metal hydride pack, which is mounted in the front hub. Pedaling along can more than double the range. A 750 Watt electric motor comes standard, mounted to the rear hub, while a 1000 Watt upgrade is available. The E+ uses its own aluminum frame and comes equipped with a decent SR Suntour front suspension fork.

Other cool details include the ability to dial in resistance to your pedal strokes for fitness reasons and a built-in security system which makes the bike all but impossible to pedal. All of these propriety features and high specifications do not come all that cheap, though, with the E+ starting at $3,495.00, available with either a cruiser or mountainbike frame.

The creators of this contraption could sure use some lessons in industrial design from Apple, or even the creators of the first generation Zune for that matter. However part of the beauty of this bike is that you can actually modify the design since you build it yourself. Atomic Zombie sells the plans for $14.99 online. You then track down the necessary parts, practice your welding skills and bolt in some batteries. The three-battery design shown has a 62 mile range. You could easily modify the design of the frame to accommodate different batteries or even equal sized wheels. It's not pretty but it will get you where you're going quietly and cleanly. You can check out a video of the LongRanger in action after the jump.

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 watts. Of course, add your human power to that power amount if you are willing to pedal. In case you were wondering, you are capable of producing much less than one horsepower! If you are willing to pay the $7,500 (!) asking price, you can find the bike at Design Within Reach.

If you do manage to cough up the money, you will be rewarded with an electric bike capable of less than 30 miles per hour box-stock. The bike has the power to go faster and can be geared to do so, but you'll need a motorcycle license for that. The asking price does include a designer helmet... The circular frame is probably where the name came from, you think?

One very cool piece of technology buried in that aluminum frame is the NuVinci planetary gearbox. This piece of hardware allows the bike to change gear ratios without actually manually switching gears. Click here for more on that. If you can afford the bike, you may also be able to spend the extra $1,800 for the solar charger, which further lowers your carbon footprint. Speaking of that footprint, just about any electric bike will offer similar CO2 output, but the Pi from Electrobike is designed with the reduction of emissions in mind, so you can feel good about that. Unless you get the gas/electric hybrid model (which will get its very own dedicated post later), which seems to fly in the face of the rest of the concept. If anybody actually does get one of these, make sure to let us know about it. It'd be interesting to compare it with a Segway, which is another really expensive way to get from point A to point B.
