In a parallel hybrid motorized bicycle, such as the aforementioned 1897 invention by Hosea W. Libbey, human and motor inputs are mechanically coupled either in the bottom bracket, the rear wheel, or the front wheel, whereas in a (mechanical) series hybrid cycle, the human and motor inputs are coupled through differential gearing. In an (electronic) series hybrid cycle, human power is converted into electricity and is fed directly into the motor and mostly additional electricity is supplied from a battery.

Hardcore MTB enthusiasts come from all over for a weekend of food, fun, and fantastic trail excursions at the Outerbike event series. eBike enthusiasts can check out the latest eMTBs and put them through their paces while enjoying vista after vista of legendary mountain bike paradises. Four event stops in Moab, UT and Bentonville, AK are planned for this year's Outerbike.
The first functioning electric motor was displayed in the early 19th century, though the device constructed by British scientist Michael Faraday did little more than swirl a wire around a magnet when an electric charge was introduced. Still, the concept proved that electricity could do work. Functional electric motors would follow in many forms after that achievement in 1821. Soon scientists and tinkerers around the world, including visionaries such as Nikola Tesla, were experimenting with all manner of electric motors -- some worked with DC power, others with AC. By the end of the century, myriad electric motors had been produced, capable of exerting enough force with enough reliable control that they were practical for use in myriad applications.
The leading U.S. developer and distributor of electric bicycles and electric scooters, Currie Technologies offers a wide range of proprietary E-bike technologies across several bicycle designs. In order to meet the needs of its target market, Currie offers a wide variety of bicycle types with varying intended uses and at a variety of price points. With a “good, better, best” approach to E-bike marketing, Currie starts with its EZIP brand for opening priced bicycles which are primarily sold through mass market and web-based retailers. The IZIP brand is reserved for its mid- to high-end offerings, sold primarily through full service, specialty retailers.
Rumour has it, the Gazelle is Europe’s most popular electric bike. We can see why. Right from the off, the bike oozes comfort. Its classic Dutch sit-up-and-beg geometry combined with pedal assist makes it a smooth, comfortable, almost effortless ride. The Bosch mid-mounted motor (in the bottom bracket shell) delivers impressive, even power with four settings selectable via the left-hand handlebar mounted button and displayed on the central Intuvia LCD display.
Thanks to clever engineering, the Electric Brompton folds up identically to the non-powered variety. It is heavier than a standard Brompton of course, but quite light by e-bike standards. It has small , suitcase-style additional wheels that come into play once folded up, and the way the weight is balanced means it is quite straightforward to trundle along in that state.  
The first regularly produced device resembling the modern bicycle was unveiled in 1818. It was called the Dandy Horse. The two-wheeled ride-on Dandy Horse was the brainchild of German inventor Baron Karl Drais, and it featured a handle bar, a padded seat, and two inline wheels of nearly equal size. What it did not feature were pedals; this was a "running machine," thus its name in German, Laufmachine. The Dandy Horse saw only a flicker of popularity, and was largely an historical footnote within a handful of years, though its design is nearly mimicked in the child's balance bike of today.
Electric Bike Conversion Kits are prepackaged sets of components designed to fit on a normal bike and convert it into an Electric Bike. These kits make it easier for end-users to find compatible, functioning parts and purchase them all together. A kit can range from a complete system that includes all the small parts you need, to DIY kits that include only a few parts and leave the rest up to the user.
Shell Eco-Marathon Americas Competition 2015 1st and 2nd Place Winners Both Used an Electric Bike Technologies Hub Motor! The Mater Dei Supermileage 3 Team of Mater Dei High School, in Evansville, Ind., took the top spot in the Battery-Electric Prototype category. The team built a vehicle using an electric bike motor from Electric Bike Technologies USA and won the electric plug in class at the 2012, 2013, 2014 and 2015 Shell Eco-Marathon Americas. They...
“Second, even if you do make bikes in the US, they will be multiple times more expensive than their overseas counterparts and 99.9% of consumers won’t pay that price. When my shop tried selling a US-made bike next to a Chinese bike, with signage that explained why the US-made bike was more expensive, we couldn’t even sell one. Customers would stand there and talk about how they want American-made goods, then they would buy the Chinese bike.”
The environmental effects involved in recharging the batteries can of course be reduced. The small size of the battery pack on an e-bike, relative to the larger pack used in an electric car, makes them very good candidates for charging via solar power or other renewable energy resources. Sanyo capitalized on this benefit when it set up "solar parking lots", in which e-bike riders can charge their vehicles while parked under photovoltaic panels.[66]

As with all these bikes, the assisted speed is capped at 15mph, but unlike some of them, the Gtech eBike City or its identical (spec-wise) sibling the eBike Sport (this just has a standard frame rather than a step-through one) is light and agile enough for you to be able pedal harder without feeling like the weight is fighting you back down to 15mph. You can even, at a push, use it without the motor on flatter roads.
As a counterbalance to the cute utilitarian bikes above, the Specialized Turbo Levo FSR Comp is a big, bad, and burly mountain bike. With 27.5-inch wheels, massive 2.8-inch tires, 150mm of travel in the front and 135mm of travel in the rear this bike is made to shred. The Specialized 1.3 Rx Trail-Tuned motor is designed specifically for off-road riding and features a double freehweel design that disengages the gear box at top speed to reduce friction while ripping downhill. The low center of gravity and stout parts make this one a relatively nimble handler that is ready for the rowdiest downhills.
