The complete integration of the Optibike is achieved from the ground up with a disign focused on high performance, safety, and ease of operation. Front and rear long travel suspension with disc brakes gives the rider confidence. The fully integrated package gives the utmost in convenience allowing the rider to ride on road, off road and the up or down the steepest hills. Optibike is in a class of its own. The Monocoque frame has sleek styling and a low center of gravity for stable handling. All electronics and long-running battery are safely housed inside the frame.
With asthma, the commuter was just what I needed to get up these hills in the DC area without having an attack. With the 20 miles range, that gets me though my day, I can almost get about 35 miles in, since I only use the assist for hills, and I call any incline a hill. It came in two days, was very easy to install. I did it myself. It took me over an hour because I was scared, and watch the video over and over. Before I install this, I never did any work on my bike, not even changed a flat. When I do group rides, people notice that I'm no longer the last person up the hills and tell me to slow down! They are impressed that I was able to installed it myself. I brought this in Feb. 2017, had one problem with the on/off switch which customer service addressed, sent me a new switch and instructed me on how to install it myself. They actually sent two switches, other than that, I had no problems with it. Great customer service that stands behind their product, great product, equals happy customer.

Information about the company’s two co-founders is scant. Storm Sondors has left virtually no trail behind him on the Internet, save for a seldom-used YouTube account. Jon Hopp is a film editor working for a Los Angeles marketing firm. His Facebook account displays photos of two fat-tire bikes virtually identical to the Storm eBike, sporting logos from different manufacturers.
E-bike usage worldwide has experienced rapid growth since 1998. In 2016 there were 210 million electric bikes worldwide used daily.[33] It is estimated that there were roughly 120 million e-bikes in China in early 2010, and sales are expanding rapidly in India, the United States of America, Germany, the Netherlands,[2] and Switzerland.[34] A total of 700,000 e-bikes were sold in Europe in 2010, up from 200,000 in 2007 and 500,000 units in 2009.[35]
Another type of electric assist motor, often referred to as the mid-drive system, is increasing in popularity. With this system, the electric motor is not built into the wheel but is usually mounted near (often under) the bottom bracket shell. In more typical configurations, a cog or wheel on the motor drives a belt or chain that engages with a pulley or sprocket fixed to one of the arms of the bicycle's crankset. Thus the propulsion is provided at the pedals rather than at the wheel, being eventually applied to the wheel via the bicycle's standard drive train.
Cost: Good e-bikes are not cheap, and unlike most bikes, the costs associated with owning an e-bike don’t end when you hand over your credit card in exchange for a shiny new steed. The average cost of operating an electric bike is around $390 a year, including maintenance and charging. You’re also likely to need to change the batteries every 3-5 years so factor that into your costs.

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.

All Kalkhoff bikes come with lots of extras: hub or motor powered front and rear lights, bells, fenders, chain guards and racks. Some include a built-in quick-lock or a rack-mounted pump. There are a number of features available for the discerning cyclist, whether it's the Magura hydraulic brakes, the B&M super-bright hub-powered headlight, the top-of-the-line Shimano internal hub or derailleurs or the three-layer powder-coated paint process.
Haibike ships the HardNine with 29-inch tires, 180-millimeter hydraulic disc brakes, a 100-millimeter front suspension fork, and a nine-speed Shimano shifting system. The bike’s LCD readout is affixed to the handlebars and displays the current speed, level of charge, remaining range, and current pedal assist mode. The company says the battery can be completely recharged in just four hours, minimizing downtime between rides.

The Stromer is tailored for riders of all types and skill levels. The patented "dual power system" allows for power-on-demand riding (limited to no pedaling), with a top speed of 20 mph and a range of up to 20 miles. Feel like pedaling? Just switch to pedal-assist mode and let the state-of-the-art torque sensor augment your pedaling efforts with motor assistance. Pedal-assist mode allows for 45+ mile range. Charging is easy with their patented removable battery system. Simply unlock the internal battery storage case on the frame, remove the battery, and charge up with any 115V power outlet (onboard charging is also available).
Instead, ebikes offer a “gateway” to exercise, says Thomas Whitaker, director of marketing for Faraday Bikes, a San Francisco-based ebike manufacturer. He notes than in their market research, 10 percent of customers use ebikes to recover from an illness or injury. “I think it’s a familiar and fun way to exercise without being hard on the body. People recover and then continue to do more and bike more.”

Thankfully, the Pendleton Somerby is an affordable option which, though not as high performing as some pricier e-bikes, offers a chance for a beginner or less serious cyclist to venture into the electric bike world. With a classic, elegant, low step through frame, getting on is as easy as possible. This is to all intents and purposes a city bike, from its look to the mudguards and chainguards that keep your clothes pristine, and the space for a luggage rack. 
Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike.[9] The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.

In 2012, two e-bike advocates completed the first 4,000-mile (6,400 km) transcontinental e-bike tour from New York to San Francisco to advocate for e-bikes in major cities across the U.S.[81] Pedego Electric Bikes is the best selling brand in the U.S. Many e-bikes in the United States are standard bicycles converted using a kit. In general, the kits include the motor (the majority of which are hub motors built into the front or rear wheel), a speed controller, throttle (usually twist-grip or thumb throttle), necessary wiring and connectors, and a battery. Several U.S. companies offer conversion kits which also offer advanced lithium battery packs. Major manufacturers also offer complete e-bikes. Trek offers a line of e-bikes using the Bionx system in which the rider programs the controller to determine how much effort the motor will give in response to rider effort, from 25% up to 200% of the rider's power. This system ensures a minimum level of rider participation and is also used to comply with many European laws mandating partial human effort before the motor engages.
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.
