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.
Go big or go home with the Yuba Spicy Curry. This is the largest of the e-bikes we’ve amassed in this collection, and it’s for the serious commuter or the person who does all of his or her shopping by bike. Even Costco runs are possible for the Spicy Curry’s powerful electric motor and the massive cargo-ready space on the bike’s sides and back. It can seat your younger kids, with low rails on the side, and features LED lights so you and your passengers stay safe. Of course, this is a bike that needs an electric boost unless you can push seriously massive watts, but thankfully, it comes with the Currie Centerdrive 500-watt motor that can make the bike go up to 28 miles per hour.
Established bike companies and startups are embracing ebikes to meet demand. About 34 million ebikes were sold worldwide in 2017, according to data from eCycleElectric Consultants. Most were sold in Europe and China, where the bikes already have exploded in popularity. In 2017, the U.S. market grew to 263,000 bikes, a 25% gain from the prior year.
In the theoretical electric bike we considered up above, we had the dynamo/motor driving the back wheel directly, simply by pressing on the tire. Most electric bikes work a different way. They have compact electric motors built into the hub of the back or front wheel (or mounted in the center of the bike and connected to the sprocket). Take a look at the hub of an electric bike and probably you’ll see it’s much fatter and bulkier than on a normal bike. You can read more about how these motors work in our main article about hub motors.
The Japanese giant, which manufactures everything from motorcycles and musical instruments to personal water scooters and motorboats, will begin selling Yamaha Power Assist Bicycles through U.S. dealers in 2018.
There’s no question that electric bikes are far better for the environment than petrol-powered car engines. But that doesn’t mean they’re completely perfect. Making and disposing of batteries can be very polluting. Not only that, but an electric bicycle is still using energy that has to come from somewhere. You may think you’re using clean green power, but the electricity you use for getting about might have come from a filthy old, coal-fired power plant or one driven by nuclear energy. (If you’re lucky, of course, it might have come from solar panels or a wind turbine!) Electric bikes are nowhere near as environmentally friendly as ordinary push bikes, but nothing is ever perfect—and, as people often say, “the perfect is the enemy of the good.” Electric bikes are certainly a step in the right direction. If everyone used them to get about instead of cars, global warming might be less of a problem, and the world would be a far cleaner and healthier place!
The Eurpopeans have it right. Pedelecs are the way to go. I have a Kalkoff. I find it so effortless to pedal that I only need to use the Eco assist level. The only time I use the standard or high assist levels are when climbing 8-10 degree hills. Because pedaling with assist is so effortless, having a throttle is redundant.
Some electric bikes claim to use a neat trick called regenerative braking. If you start pedaling the bicycle or going downhill, the spinning wheels turn the electric motor in the hub in reverse and start charging up the batteries. In practice, regenerative braking is nowhere near as useful on an electric bicycle as it is on an electric train or car. An electric bike has much less mass and velocity than either a train or car, so it never gains (or loses) anything like as much kinetic energy when it starts and stops. You’d have to go down an awful lot of hills to charge up the batteries completely and that’s usually not practical. And what’s the point in pedaling the wheels simply to charge the battery? You might as well have bought an ordinary bicycle to start with!
Say you’re a responsible 20 mph max rider using proper power, but someone idiot car driver opens their door and you have no time to avoid the whack! You don’t have a helmet on (which is the law in Calif. using power assist). On a regular bike the idiot car driver would be liable for your injuries. Since you weren’t wearing a helmet their insurance rep could argue court you were negligent and broke the law…hence your brain injury was YOUR fault, not the car driver. Same would happen if they discover you monkeyed with the max. speed sensor…or the max power level.
The oldest patent for an electric bike I’ve been able to find at the US Patent and Trademark Office is this one, by Ogden Bolton, Jr. of Canton Ohio, which was filed in September 1895 and granted three months later. You can see from these original diagrams that it bears an amazingly close resemblance to modern electric bikes. In the general picture on the left, you can see there’s a hub motor on the rear wheel (blue), a battery suspended from the frame (red), and a simple handlebar control to make the thing stop and go. In the more detailed cutaway of the hub motor on the right, you can see there’s a six-pole magnet in the center (orange) bolted to the frame and an armature (made from coiled wire, yellow) that rotates around it when the current is switched on. It’s quite a hefty motor even by modern standards; Ogdon mentions “a heavy current at low voltage—for instance, to carry one hundred amperes at ten volts.” So that’s 1000 watts, which is about twice the power of a typical modern bike hub motor.
Electric trikes have also been produced that conform to the e-bike legislation. These have the benefit of additional low speed stability and are often favored by people with disabilities. Cargo carrying tricycles are also gaining acceptance, with a small but growing number of couriers using them for package deliveries in city centres. Latest designs of these trikes resemble a cross-between a pedal cycle and a small van.

when the motor produces maximum continuous rated power of not more than 250 watts (n.b. the motor can produce more power for short periods, such as when the rider is struggling to get up a steep hill).
For a lawyer, you didn’t get what the federal law states. The federal law overrides all state laws and defines an e-bike as a bicycle. According to the New Jersey state MVO, e-bikes must be registered but they can’t be registered because they do not meet federal safety standards for motor vehicles – not on the list of approved motorcycles. The federal law overrides these anal idiots. E-bikes that meet the federal definition of an e-bike, are bicycles in all states. This is the entire purpose of the federal law! To prevent anal bureaucracy states from stopping the sale and use of these environmentally friendly e-bikes.
Pedal assist, also referred to as pedelec, is a mode that provides power only when you are pedaling. If you are used to riding a traditional bike, the pedal assist mode has a more intuitive feel compared to the throttle mode.
Although there are plenty of other e-bikes that impressed us, we wanted to choose three that stand out for a few reasons. But before we continue, an honorable mention goes to the Copenhagen Wheel. If you’re not sure where to start, the Copenhagen Wheel can fit on most bikes and can even be ordered fully installed on a few bikes. More to come on that.
Photo: Could solar power be the future of electric bicycles? The large solar panel mounted over the back wheel of this experimental bike powers an electric motor connected by a chain drive to the back wheel, helping the rider when he doesn’t feel like pedaling. Using clean, green solar power would remove the problem of having to charge electric bikes with electricity generated from fossil fuels—and help to extend their range significantly.

S-Pedelecs: have pedal-assist only, motor power can be greater than 250 watts, can attain a higher speed (e.g., 45 km/h) before motor stops assisting, legally classed as a moped or motorcycle (not a bicycle)
The GenZe app works through Bluetooth connection on the 200 series e-Bikes only. The app can be used to understand range and battery life, plan routes, track ride history, and measure exertion. The 200 series e-Bikes also come with a phone mount and integrated USB charger to keep you charged and connected while you ride.
Size: Some electric bikes look a little small, but if you’re going to drive to the edge of the city and ride the last couple of miles, a light, folding model that you can easily throw in the trunk has definite advantages.
Built with durable e-bike rated components, the Archer is ready for trails and pot-holes. The oversized axles and adjustable suspension provide a confident feel as you race down the trails or streets.
Free to Roam the Road: According to California state law, any pedal-driven e-bike with a max speed of 20 mph can use any of the state’s bike lanes, bike paths, bike trails or off-street bikeways. (E-bikes are still pretty new, so in many areas, the CA law is the accepted standard in absence of local regulations.)
In full-electric mode, the Pedego City Commuter Classic Electric Bike is capable of moving at up to 20 mph for anywhere from 15 to 30 miles. There are two further options: power-assisted pedaling or fully “unplugged” riding. Renowned Shimano gears are easy to select. Seldom do we come across a product so universally praised by owners. It’s not cheap, but comments like “Everything I hoped for!” and “Outstanding!” tell us that it’s money well spent.
As is always is the case with companies that launch products on Indiegogo, there’s a chance those things never happen. But if you’re in love with the idea and don’t particularly want to roll the dice on a startup, there are plenty of similarly priced portable batteries and solar panels already available on the market, and an abundance of e-bikes at or under Kvaern’s price tag. You might have to do a little comparison shopping if you want to find something that matches the Copenhagen startup’s style, but you’ll certainly be able to ride the sun’s rays a lot sooner.
The two most common types of hub motors used in electric bicycles are brushed and brushless. There are many possible types of electric motorized bicycles with several technologies available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design with the motor built into the wheel hub itself and the stator fixed solidly to the axle and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.

More powerful pedelecs which are not legally classed as bicycles are dubbed S-Pedelecs (short for Schnell-Pedelecs, i.e. Speedy-Pedelecs) in Germany. These have a motor more powerful than 250 watts and less limited, or unlimited, pedal-assist, i.e. the motor does not stop assisting the rider once 25 km/h has been reached. S-Pedelec class e-bikes are therefore usually classified as mopeds or motorcycles rather than as bicycles and therefore may (depending on the jurisdiction) need to be registered and insured, the rider may need some sort of driver’s license (either car or motorcycle) and motorcycle helmets may have to be worn.
A few electric bikes incorporate a technology that started in racecars: regenerative braking. When you brake, you create energy. That energy can be harvested and fed back into the battery, prolonging its life. Regenerative braking is only just being introduced to e-bikes, but it’s certainly something to watch out for.
