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.
China's experience, as the leading e-bike world market, has raised concerns about road traffic safety and several cities have considered banning them from bicycle lanes.[2] As the number of e-bikes increased and more powerful motors are used, capable of reaching up to 30 miles per hour (48 km/h), the number of traffic accidents have risen significantly in China. E-bike riders are more likely than a car driver to be killed or injured in a collision, and because e-bikers use conventional bicycle lanes they mix with slower-moving bicycles and pedestrians, increasing the risk of traffic collisions.[2]

No day or ride is the same. Monday could be morning park laps, while Saturday might mean a day in the woods. If this is familiar, you need a bike like the CrossTrail. It has a responsive, durable aluminum frame, while our Body Geometry Fit science and a Multi-Circuit Damping fork ensure comfort over any terrain. Put it all together, and you have a bike that's just as versatile as yourself.
Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.[43]

Introducing a fully integrated, electric-assist mountain bike that takes our Altitude’s legendary handling and ride quality and adds a compact, powerful drive system. The new Powerplay™ drive system was designed in parallel with the frame, delivering ultra-short chainstays, optimised suspension kinematics, super-low centre of gravity, and class-leading torque. The result is an e-MTB that actually rides like a proper mountain bike—perfect for everything from self-shuttling all mountain trails, finding flow between the descents, and squeezing in power lunch rides. 
Government agencies like the USDA National Forests and the Bureau of Land Management should distinguish between electric pedal-assist eBikes (Type 1) and self-propelled eBikes (Type 2). The former are still human-powered whereas the latter are fully motorized like a motorcycle. Some states like California are already recognizing the different classifications of eBikes and allowing some on trails while prohibiting others. This clear distinction should help us avoid expanding our mountain bike trails to motorcycles, or worse yet, have trails that are currently open to mountain bikes relegated to “hiking only.”
Whether you need a bike to help you stay fit and active, or you just want something comfortable to get around town on, we have a hybrid bike that's tailor made for however and wherever you ride. Each bike represents an intuitive design that's purpose-built for the task at hand. So get out and get exercising, rolling through woods, commuting—whatever. All that we care about is that you're having the time of your life on the perfect bike.
Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.

Here is your experience amplifier: Spectral:ON gives you more trails per hour. The RockShox Yari RC suspension fork offers the steering precision and rigidity you need for e-biking with its 35 mm thick stanchions, the RockShox Deluxe R shock absorbs at the rear of any obstacle. For the wheels you can rely on the DT Swiss H1900 Spline wheels with reinforced hubs, freewheel bodies, spokes and rims, specially developed for the E-MTB. Schwalbe tires combine top traction with low rolling resistance. Magura's MT Trail Sport brakes with 203mm front and rear rotors will stop you when you need to. With Spectral:ON 6.0, your greatest adventures are yet to come.
With 170mm travel, aggressive angles and Shimano’s superbly calibrated STEPS motor, the Focus Sam2 is an enduro bike with a built-in shuttle. With the bolt on TEC pack you really can climb to new heights, but without it the smaller capacity internal battery means you need to be ultra economical with your energy use. It’s also frustrating that the internal battery can’t be removed easily for charging. By far the biggest frustration with the Jam2 though is that the sizing isn’t very generous and standover clearance is limited. It’s still a great e-bike, but when you’re spending this much money, you can afford to be fussy.

My second e-bike, and it is amazing. 40 miles range on full assist, 4 levels of torque sensor assist, one level cadence sensor assist, one level throttle only, 20 speed, forks have 120mm of range, and the 500 watt battery is very powerful. The seat was too hard, so I replaced it with a gel seat and installed a BodyFloat under the seat. Also installed a rack.


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.
