Photo: Zap Electric’s power-assist kit turns a conventional bike into an electric one. There’s a bolt-on DC electric motor (weighing just over 3kg or 7lb) just above the back wheel, behind the police officer’s foot, pressing against the tire and driving it by simple friction. The motor’s powered by a compact lead-acid battery (weighing about 5.5 kg or 12 lb) inside a protective nylon bag. This kit adds quite bit of weight to the bike, but gives extra range and speed when needed. Photo taken in Santa Rosa, California courtesy of US DOE/NREL.
The Surprising Health Benefits of an Electric Bike by Gretchen Reynolds. The New York Times, July 6, 2016. Electric bikes can encourage motorists back onto two wheels, with real benefits to their health.
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…

Yes, They Still Count as Exercise: A new University of Colorado Boulder study says that regular e-bike usage has health benefits. Though they’re pedal assist, a e-bike can still give you a workout, improving your cardiovascular health, fitness, and aerobic capacity. The results were most prevalent in previously sedentary riders.
The Stromer ST1 Platinum may look less decked out than the other models, but this e-bike is pretty high-tech. It looks like something a Storm Trooper might pilot and has a futuristic computer readout to go with it—showing speed, odometer, trip time, and battery level, among other things. The battery is built into the down tube, and the speed tops out at 28 miles per hour. It also has fender and rack mounts if you want to make it a great commuter bike in the winter and can go up to 55 miles on a single charge.
The situation in New York State is not as bleak as you imply. New York State has yet to define what an electric bike is, so in the meantime the federal definition applies (an ebike goes less than 20mph, with less than 750 watts of power). The federal definition says that any bicycle within these specifications is not a “motor vehicle” or a “motorized vehicle” or a “motorized bicycle”; it is essentially a bicycle. Only state laws for bicycles apply. This makes sense: the intent of the federal law was to define a reasonable speed and power for ebikes that isn’t significantly different from human power. We’re talking about a vehicle that by definition is not capable of behaving significantly differently than a human-powered bicycle, so it should have the same benefits and restrictions as a human-powered bicycle. States like New York State that simply don’t define ebikes don’t have a basis for restricting them, except by referring to the federal law. It may be that this very clear idea needs to be tested in court, or it may be that Albany comes to its senses and passes a legal definition of ebikes similar to the Federal definition.
If you keep reading the NM statutes, you see no exceptions to the traffic laws for mopeds. You get to ride with no registration, but you don’t get to ride any way you please. “Bicycles” have to obey the traffic laws too, by the way. Similar to Texas, lights at night, stop at the stop sign, ride on the right side of the road, obey speed limits, etc.
My ebike allows for both the throttle and pedal assist to work together. I really like it because I can use the throttle while going through corners where I might ground my pedal. I also use it when negotiating tight places. The pedal assist works great on long hauls and not having to keep your hand on the throttle. If I had to choose one it would be the throttle because I can control the exact amount of assist at any given moment.
Globally, electric bicycles outsell electric cars by a wide margin. An estimated 29.3 million e-bicycles were sold in 2012, with perhaps 90 percent of those selling in China, which has more electric bikes than cars on its roads. E-bicycles are popular in Europe, too, selling about 380,000 a year in Germany and 175,000 in the Netherlands in 2012. By comparison, about 120,000 electric cars were sold worldwide.
This step-through frame will make your commuting life or weekend errands infinitely easier, with speeds of up to 20 miles per hour and an electric assist motor that will power you for up to 50 miles. The Evo Eco Lite rides smoothly and handles like a normal bike—and looks like one too, thanks to careful battery and motor placement. Front and rear fenders plus a rear rack make it easy to ride to work, the library, or the grocery store. It has a simple app to go it, but you can upgrade to the Premium app, or add a GPS Tracker, a winter battery cover (for snowier climates), or a lighting cable as extras.
Budget Travel: Many e-bikes are cheaper to operate per mile than a car. According to e-bike manufacturer Elby’s calculations, the average annual cost of maintaining and operating a car is $9,283. Compare that to their calculated average annual cost of maintaining and operating an e-bike, which is just $390. The fuel’s cheaper, too: the cost of a 12-gallon gasoline fill-up is about $33.60 (12 gallons at $2.85/gallon). Cost to fully charge an e-bike, on the other hand, is about $0.50 (480 watt/hr battery at $0.10/kwh).
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.
It’s Easy to Plug In: If you can find an outlet, you can charge your bike. Unlike electric cars, which require dedicated charging stations, most e-bikes plug in anywhere. Some even have removable batteries, which make it even more convenient to charge. (Elby says to plan around four hours to get their e-bikes fully charged.)
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. 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.
Brush motors are common because they’re durable and rather inexpensive to produce. However, modern brushless motors are lighter, smaller, and more powerful than brush motors, and they can be almost silent. E-bikes with brush motors cost more, but they require no maintenance. As a result, most electric bikes now have a brush motor.
Riding Position: You also may wish to check out an e-bike’s riding position before investing in it. For short trips, the riding position might not make much difference, but for long journeys, the upright “Dutch” style with pulled-back handlebars is very comfortable – particularly for tall riders. The same goes for mountain bike styles, though these bikes are not often designed to actually go off-road.
In terms of how far you can go, there’s a big difference between a pedelec (pedal-assisted electric bike) and full-time electric bike. If you’re prepared to pedal and only need help on hills, you could get anywhere from 50 to 100 miles on a single charge with the former.

Full-power: These bikes are designed for minimal pedaling over relatively short distances. They have large batteries and powerful hub motors and they tend to be big, sturdy, and heavy. Bikes like this are for people who love cycling but hate pedaling! Since you’re using power all the time, the range is limited (typically 16–30km or 10–20 miles).
Fat E-Trike from Sun and E-BikeKit™ at Interbike 2014 Fat bikes and electric bikes were all the rage this year at interbike in Las Vegas. It seemed almost every bike vendor at the show has at least one fat bike model in their booth this year. On top of the fats were the electric bikes. And I think it goes without saying that nobody wants to actually pedal a fat…
Power-assist: Also known as pedal-assist bikes, these are the bicycle equivalents of hybrid cars: they’re designed to be pedaled quite a lot of the time and electrically powered either when you’re tired or when you feel like a bit of electric help (when you’re going up hill, for example). Unlike full-power bikes, they don’t have hub motors; instead, there’s a separate electric motor mounted near the rear wheel and driving it either through the gear sprocket or simply by pressing against the rear tire. Where a hub motor is difficult or impossible to pedal without any power (because you’re effectively turning it into a generator), power-assist motors turn easily with little or no resistance when you pedal. That gives power-assist bikes much greater range than hub-motor ones (as much as 80–145km or 50–90 miles).

Specialist off-road electric bikes aren’t legal for road use, so we’re not spending a lot of time on them in this review. However, you may be interested in learning a few facts about these monstrosities. They’re lightweight yet tough with fat, all-terrain tires, advanced brakes, and speeds in excess of 50 mph.
E-bikes come in some pretty strange shapes and sizes these days. With a missing seat post, the BMX-inspired e-bike does have some points of difference, and also comes with an optional solar-powered charging pack so you can stay on the move without tapping into the grid.
Interestingly, it appears that if I wanted to, I could also ride it as a moped. In the example, 36V makes it go 23-MPH. With 48V, it would go about 28-MPH, and have about one and a half horsepower. As a moped, note that it does not require the bike to have pedals. As a motorized bicycle, it IS required to have fully operable pedals.
