In a friction drive motor, a small, solid wheel rotates against the side of the tire in order to drive it. The first motorcycles used the same concept, with a motor mounted above the front wheel. The problem is that the drive rubs at the side of the tire. It's inefficient, and it quickly wears the sidewall away. Tires need to be replaced every couple hundred miles. For this reason, you'll seldom see electric bikes with this type of drive anymore.

Those buyers aren’t likely to get a major workout. Researchers from the University of Tennessee found in a study of walkers, ebike riders and traditional bike riders that those who completed a 4.43-kilometer hilly route on an ebike used 22 percent less energy than traditional bikers and 64 percent less than walkers, most likely because the ebikers got to the finish line faster than the others. But perks included higher levels of enjoyment and no need for a shower when they were done.
Comfort. Like any other type of bike the electric bike should offer you a comfortable ride. All general components such as, saddle, handlebars, the geometry of the frame should put you in a comfortable position. If the bike doesn’t satisfy these criteria it’s certainly not the best electric bike on the market. After all you’re going to spend quite a lot of time riding it, so you might as well look for a more comfortable solution.
FRAME GEOMETRY  EcoBike electric bikes have been specially designed with the daily commuter in mind. The frame is constructed from a high-strength, lightweight 6061 aluminum alloy that maximizes safety and durability.  The enhanced frame design features comfort ergo-geometry that is more upright than a traditional mountain or road bike.  Every EcoBike electric bike is outfitted with suspension on both front forks (except Vatavio) and seat post to deliver a smoother ride. 
Come for the price, stay for the awesome. The August Live! LS is one of the lower-cost e-bikes you’ll find. What it lacks is gadgets it makes up for in flare and retains just what you need. You won't find a digital display or integrated lights, Instead you get trendy, chopper-style handlebars, a sweet paint job, and a 250 watt motor that is more than capable of tackling steep hills without a second thought. That said, this bike just begs to be ridden on casual cruises down the boardwalk or bike path.

The two most common types of hub motors used in electric bicycles are brushed and brushless. Many configurations are 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. The motor is 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.
ELECTRONIC CONTROL  The Zero-Smart-Start speed controller delivers ease of use and smooth drive control and offers a multi-function variable speed output.  It is state of the art, producing consistent efficient power.  The automatic Pedal Assist mode produces a power burst that dramatically assists the pedaling effort.  The Zero-Smart-Start electronic throttle control allows the rider to relax and not pedal at all. 
The Espin is powered by a 350-watt motor that’s rated for trips up to 50 miles (depending on the terrain and assist level). Once depleted, the battery fully charges in roughly five hours. Thankfully, Espin makes it easy to remove the battery, allowing you to quickly recharge it at home or in the office between trips. A backlit LCD control hub displays your basic metrics and battery life while in transit and LED headlights add a touch of light when needed.
“Our first-generation bike used the same type of 36-volt, 10-amp-hour battery,” he says. “It got between 20 and 30 miles of range, and that’s riding with pedal assist. Using just the throttle you might get 20, less if you’re running on sand or up hills. The charge time is also problematic; with that kind of battery you’re looking at four to six hours, not 90 minutes.”

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.[14] In the United States, many states have adopted S-Pedelecs into the Class 3 category. Class 3 ebikes are limited to <=750 watts of power and 28 mph.[15]

Even though it’s a hefty amount of money to fork over upfront, LaLonde says you’ll likely save money in the long run. If you use public transportation, do the math to see how much you could save over time. If you choose an e-bike over a car, you’re foregoing auto maintenance, gas, insurance, parking fees, and potential tickets, LaLonde adds. “So while there’s sticker shock for a first-time bike buyer, it can still be cost-effective.”

Of course the specs are nuts. Shimano Deore XT Shadow+ drivetrain, Magura MT4 hydraulic disc brakes, Mach 1 rims, and Schwalbe G-One tires make this not only an incredible commuter, but really a solid racing bike if you want to challenge another ebiker. The G-One tires I just love. They’re slick enough to keep you up to speed, but have a good amount of knobiness so that you can handle bad weather.


The Patriot DreamE results from the combination of the popular Day 6 bicycle with the Kinetic8-Fun mid-drive motor kit. The unique Day 6 styling eliminates leaning forward, so you sit perfectly upright. That means there is no more stress on wrists, neck, back, and crotch. It also means a superior breathing position and a better way to enjoy the scenery. The step-through design makes for easy mounts and dismounts, while the low seat allows the rider to reach the ground with both feet for stability and safety.

TerraTrikes make great electric recumbent trikes. Here are a few how to tips for converting the Rover and Rambler models, specifically with internally geared hubs. The TerraTrike Rover and the rambler models both are offered with internally geared hubs. It is possible to convert the trike to external gearing, but you will probably want the help of a bike shop that is familiar with recumbents. For a good bike shop,...

Tackle your daily commute with ease or go for a weekend cruise in style with the Gazelle CityZen T10 e-bike. And don’t worry about those thigh-burning hills; the Bosch motor offers four assist levels—Eco, Tour, Range Sport, Turbo—making hills a breeze and the Lithium-Ion battery provides a range of up to 85 miles in Eco mode. The bike is one of the first to use Bosch's new integrated battery, which is concealed in the downtube. The matte black paint and classic, step-through design give a classic look while fenders, pannier racks, and integrated lights add practical functionality. The bike is easy to maneuver in city streets, but still has assist up to 28mph so you can cover a lot of miles and power up steep hills. There's a suspension fork too. It's not at the level of something you'd find on a mountain bike (or even some better e-bikes) but it takes the edge of some potholes and curbs.
