For many bikes, battery range is more important that total power (because they're all pretty powerful). You want a bike that delivers a range long enough for your rides at the power levels you want. Most e-bikes will have three to five levels of assist kicking in anywhere from 25 percent of you pedal power to 200 percent boost. Consider how fast the battery takes to recharge, especially if you'll be using your bike for long commutes.
It’s probable that GM was hoping for more press for its announcement of the same day as Musk’s interview going live, that it had actually built and was going to sell a pair of electric bikes. It launched a $10,000 naming contest. The bikes were built in-house by GM, including engineers who had worked on the Bolt. The Director of General Motors Urban Mobility Solutions, Hannah Parish said:
It's what's inside your motor that sets it apart from the rest. Quality parts and assembly We've written here before about how to choose a motor, the different types of motors, the performance differences between motors, etc. But today I want to show you what makes our motors different from other hub motors. Today, harry is replacing the axle on a customer's direct-drive motor. The bike was crashed and the...
Installing an electric bike kit is easy to do, can be done in just an hour or so and can last for many years if done right initially. Deciding on the right electric bike conversion kit, the one that suits your riding style and your bike best, is the most important decision you’ll make during this process. Good news... you’ve come to the right place!

Nicolas Zart Nicolas was born and raised around classic cars of the 1920s, but it wasn't until he drove an AC Propulsion eBox and a Tesla Roadster that the light went on. Eager to spread the news of that full torque, he was invited to write for various CleanTech outlets in 2007. Since then, his passion led to cover renewable energy, test drives, podcasts, shoot pictures, and film for various international outlets both in print and online. Nicolas offers an in-depth look at the e-mobility world through interviews and the many contacts he has forged in those industries. He particularly enjoys communicating about the new e-mobility technology and what it means to us as a society. Today he focuses most of his writing effort on CleanTechnica, a global online outlet that covers the world of electric vehicles and renewable energy. His favorite tagline is: "There are more solutions than obstacles."

Your friends: We all have friends we wish wanted to pedal up hills with us. Many of who might be capable of leaving us in their dust on descents. These are young and old riders; riders lacking the fitness, time, motivation, or who just aren’t interested in climbing alone, at the back of the pack. You’ve done everything to get them back out riding with your regular crew, but pride and reluctance to hold the group back is keeping them away. 
While we’re on this thread, I want to go ahead and throw in the most tricked-out shred sled in the AllMtn line. Haibike spared no expense wit the XDURO AllMtn 10.0. It’s a premium bike, and here is why. A Fox Factory 34 front suspension fork with 150mm of travel and Kashima coating starts things off. That’s followed by a 20-speed drivetrain brought to you by Shimano Deore XT Shadow Plus. Then you’ve got DT Swiss rims, KS LEV-DX dropper seatpost, Magura MT7 HD brakes, and a Yamaha PW-X motor. ‘Nuff. Said.
Pedelecs are much like conventional bicycles in use and function — the electric motor only provides assistance, for example, when the rider is climbing or struggling against a headwind. Pedelecs are therefore especially useful for people in hilly areas where riding a bike would prove too strenuous for many to consider taking up cycling as a daily means of transport. They are also useful for riders who more generally need some assistance, e.g. for people with heart, leg muscle or knee joint issues.
Sleek, powerful, and modern. If those characteristics strike a chord for you then the Bulls E-Core bike could be the pick of the litter so to speak. Each handsome yet power-infused ride is assisted by Shimano’s new 250W E-8000 eMTB motor alongside a 375Wh power pack. Thanks to this power plant, this sweet ride boasts enough juice and torque to conquer and climb even the toughest of trails. Additional features include a 180mm front RockShox Lyrik, a rear Fox Float X2 Air suspension to smooth out that descent, Di2 XT electronic shifting, and 203mm Shimano XT hydraulic disc brakes.
Certainly very excited about this e-MTB. Bulls has decided to make use of the super powerful Shimano Steps E8000 motor. With a 500 wH battery and a 250 watt motor, this bike will assist you up incredibly steep hills but not burn too much of the battery. Bulls also sets this bike apart by setting it up with Shimano Di2 electronic shifting and a Deore XT drivetrain for precise and quick shifting. The other specs are about what you’d expect from a ride in this price range. Magura MT5 hydraulic disc brakes, RockShox suspension with 150mm of travel, and Rocket Ron tires on tubeless ready rims let you take on any mountain trails.
Generally speaking, e-bikes are bicycles with a battery-powered “assist” that comes via pedaling or, in some cases, a throttle. When you push the pedals on a pedal-assist e-bike, a small motor engages and gives you a boost, so you can zip up hills and cruise over tough terrain without gassing yourself. Called “pedalecs,” they feel just like conventional bikes—but better, says Ed Benjamin, senior managing director at the consulting firm eCycleElectric. “You control your speed with your feet, like with a regular bike,” he says. “You just feel really powerful and accelerate easily.”
While the first functional battery was developed in the year 1800 by Italian physicist Alessandro Volta, a practical battery would not be seen for several decades yet. By the end of the 19th century, practical and portable batteries were more widely available, this finally freeing the electric motor to be used in a wide new array of applications. It might come as a surprise, but the electric motor, battery, and a bicycle were first paired as far back as the 1890s. It would be approximately 100 years later that electric bicycle development finally entered the mainstream, but the technology and concept behind the electric bike were all in place generations ago.

Cape Fear Community College students are utilizing the E-BikeKit™ electric bike kit in the designing and building of their own electric bicycles!   ORIGINAL ARTICLE POSTED by the Port City Daily staff "CFCC student-built electric bikes to be in Azalea Fest parade Some innovative designs by Cape Fear Community College students will be featured in this year’s N.C.

A low-mounted motor keeps the centre of gravity low and the entire system compact, while allowing for ultra-short chainstays and a bottom bracket that is integral to the frame. We use a high efficiency, three-phase brushless motor to provide class-leading torque and ultra quiet operation. To get instant power response on trail, we put the torque sensor between the chainring and the drive gear, and our 48v battery voltage allows for super fast charging.
If you’re looking for even more performance and an even more refined bike, you’ll find what you’re looking for at Specialized. Their bike embodies the company slogan “Innovate or die” in a perfect way and is full of smart solutions. Many of them, such as the specially developed app for tuning the motor, the integration of the battery, and the small remote lever for selecting the support level, are obvious. Some, on the other hand, only become clear when you take a closer look – such as the Autosag valve on the shock for a simplified setup process, or the omission of a spoke magnet. The Levo also won us over with its outstanding riding characteristics, obviously. It rides comfortably, climbs quickly and efficiently, and has exactly the right mix of agility and stability. It’s the ultimate machine that promises to bring a huge smile to every rider’s face after just a few metres on board – no matter whether beginner or a pro. The Specialized Turbo Levo S-Works Carbon is currently the eMTB offering the best overall package, and thus the deserved Best in Test! The best eMTB of the 2018 season!
By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle.[7] Schnepf's invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.[8]
