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.

Automated Transit Networks (ATN), and the small-vehicle subset of Personal Rapid Transit (PRT), are emerging technologies that can help solve the related problems of congestion, dependence on foreign oil, and planetary climate disruption. ATN/PRT offers clean, quiet, responsive public transit with automated non-stop service available 24 hours a day. In addition to these service benefits, PRT costs far less to build and operate than other transit options ¯ and is safer than walking and cycling on nearby busy streets.

Bottom Line The Specialized Turbo Levo FSR Comp 6Fattie was the most well rounded bike in our test, the winner of our Editor's Choice Award. Commencal's first foray into the e-bike market was worth the wait with a hard charging ride that utilizes their Meta frame design and Shimano's E8000 motor. The HaiBike XDURO AllMtn features a powerful pedal assist motor, but in a less refined package. The Trek Powerfly 7 FS is a good electric mountain bike, but its component specification is holding it back from reaching its potential.
There are many places in the U.S. where you can legally and responsibly ride e-MTB's, and take it from us, they are a heck of a lot of fun. Check with local land management agencies to find out where you are allowed to use an electric mountain bike before taking to the trails. One thing we do know, e-MTB's can be used on any trails that are legal for motorized use, so we took advantage of the wealth of OHV trails in the greater Lake Tahoe area for our testing purposes and had more fun doing it than any of us expected.

Of course, there is room for improvement. There is no handlebar mounted digital display and the only way to tell your speed is to mount a phone or bike computer to the bars. To see your battery life, you have to stop and look to the side of the frame (or risk crashing). The climbing performance was hampered by the drive unit's more abrupt cutoff when the pedals stopped turning. The charger connection is poorly designed and located: we spent a fair amount of time carefully removing mud to get the bike to charge. Overall though, the Specialized still proved to be the test team's favorite for its versatility and well-rounded performance. We loved it and we think you will too, read the full review to find out more about our Editor's Choice Award winning e-MTB.
This isn't just the lightest mountain bike frame we've ever made, it's our lightest frame—period. The Men's Epic Hardtail was redesigned from the ground-up to give you an unparalleled performance advantage on the XC track. It flies up hills with ease, sends descents with confidence, and wastes nary a watt. Consider it a cross country revolution, and remember, this is going to be epic.

He would struggle to ride a normal bike very far but is thinking of getting an E bike to get him back into cycling with his young son. Knowing how destructive I used to be at a lower body weight, can anyone recommend a very sturdy E bike? He doesn't have a lot of money and I just worry he could get a bike which will not be able to take his weight. Any suggestions for a bike available here in the UK would be much appreciated.


If you really want to see the future take a look at the Fazua Evation, with a battery and motor this system weighs an incredible 4.7kg! The battery only has 250wh, but at 1.3kg you could easily carry a spare in a pack. The really interesting thing about this system though, is the motor and the battery can be removed from the frame, so you really do have two bikes in one.
Riding a pedal-assisted road bike may seem counterintuitive but during longer training sessions, the minimal addition of power helps prevent overall muscle fatigue and injury. Similarly, those looking to enjoy longer scenic routes will appreciate the general boost an electric drive provides. With a top speed of 28 mph, the Road E+1 uses three power modes to give you ultimate control over your ride and assistance level. A four-point sensory system monitors the pedaling force allowing the motor to amplify your movements seamlessly.
The first functioning electric motor was displayed in the early 19th century, though the device constructed by British scientist Michael Faraday did little more than swirl a wire around a magnet when an electric charge was introduced. Still, the concept proved that electricity could do work. Functional electric motors would follow in many forms after that achievement in 1821. Soon scientists and tinkerers around the world, including visionaries such as Nikola Tesla, were experimenting with all manner of electric motors -- some worked with DC power, others with AC. By the end of the century, myriad electric motors had been produced, capable of exerting enough force with enough reliable control that they were practical for use in myriad applications.

“Rather than bolt on a bulky off-the-shelf system, we struck out on our own to redefine the category. The Powerplay system is the result of designing an electric drive for the suspension and geometry needs of proper mountain bikes; in fact, the geometry and pivot points of the Altitude Powerplay are identical to those of the new Altitude. In our opinion this is the first electric bike that actually rides like a mountain bike should.”
Sure, you train hard and eat right, but there’s just one thing missing—an edge. The Amira gives you two. First, there’s the performance edge you get from its FACT carbon frame and tapered head tube. The combination results in responsive handling and true get-up-and-go accelerations. Then comes the psychological edge. The feeling that, when teamed up with a lightweight, high-performance machine, there’s no limit to what you can achieve together.
In the geared motor, a small and lightweight motor spins very fast inside. The electric bike motor then uses a planetary reduction gear inside the motor to reduce the rpm to the correct speed for a bike wheel. Electric Bike Motor An electric bike motor on an electric bike can be any kind of electric motor. There have been some very creative home brew e bikes that used any motor...
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.

This is a question the designers and engineers of the FOCUS and BULLS bikes of this group test asked themselves. Instead of speccing them with the standard 500 Wh batteries, both have developed a sophisticated alternative. The idea: instead of riding around with unnecessarily large batteries and unnecessary weight on short tours, they integrated a smaller 375 Wh or 378 Wh battery into the bike. If you don’t have enough power for long loops, you can double the range of both bikes with an additional battery for up to a full 750 Wh. While the second battery is mounted in the front triangle of the FOCUS, it disappears sideways in the downtube of the BULLS. In practice, you’ll need the second battery relatively often with both bikes, and in either case, you should consider the additional € 499 investment in a second battery pack when you buy the bike.
A 2008 market survey showed that the average distance traveled in the Netherlands by commuters on a standard bicycle is 6.3 kilometres (3.9 mi) while with an e-bike this distance increases to 9.8 kilometres (6.1 mi).[79] This survey also showed that e-bike ownership is particularly popular among people aged 65 and over, but limited among commuters. The e-bike is used in particular for recreational bicycle trips, shopping and errands.[79]

Where efficiency and capability cross paths on the trail, you'll find the Men's Rockhopper. The reasons are pretty simple. Sure, as a hardtail, it has some natural climbing ability, but what isn't so obvious is the low bottom bracket, roomy top tube, and ultra short chainstays. In other words, it puts out a planted, confident, and snappy ride over a diverse array of terrain. It's fast on the way up, and even faster on the way down.

This Saturday, Oct. 7, Tim Sway will showcase his “UpTriCycle” at the Greater Hartford Mini Maker Faire. Sway calls the UpTricycle an “off grid, electric, solar charging mobile maker space and carrier for upcycling makers.” He uses minimal tools and footprints in his creation for unlimited potential. On his YouTube page, Sway made a comparison video between a gas-powered trike and an electric trike. He purchased a gas-powered trike first,...
There are two main types of motor to suit different riding styles. The durable, "heavy duty" Direct-Drive motor, and the lightweight, efficient and fast "performance" geared motor. Electric Bike Motors, hub motors in particular, and electric bike batteries are what make electric bicycles go. Using a hand throttle you control the flow of electric current from the battery to the brushless motor. With an intelligent 20 Amp controller regulating the...
If you are a regular bicyclist who wants to add some excitement to your rides or wants some help with those hills, a full sized electric bike is the way to go. If you are considering a bike as a means of transportation more than an outlet for amusement, then a smaller, folding electric bike is the convenient choice. In each category, consider the speed and range you want, as these factors impact price.
eMTBs appeal to an extremely broad target group: some use their eMTB for daily commuting, others for after-work or weekend rides on maintained gravel roads, and others plan to do an electrified alpine traverse or even an action-packed visit to the bike park. The good news is that many eMTBs are jacks of all trades, covering a very wide range of uses. Others, unfortunately, may disappoint with poor spec or nervous handling.
Two bikes clearly set themselves apart from the rest of the test field: the brand-new BULLS E-CORE EVO EN Di2 and the Specialized Turbo Levo S-Works Carbon. Both brands are huge players with great innovative power, and you can tell this from their bikes. The BULLS impressed with its cleverly thought-out modular battery concept, top-end, well-considered spec, and very balanced handling. “Climb aboard and feel at home” is its tagline. Thanks to the 180 mm of travel, the bike offers plenty of reserves for those larger hits, yet still feels agile and playful. With this brilliant combination, the € 6,499 BULLS secures itself the desired Best Value tip!
This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection - our Direct-Drive motors are now all High-Torque 6x9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the...
The battery life, however, is outstanding! My brother has a similar e-bike that uses the exact same motor, but mine seems to get nearly double his range. I’m pretty sure that is not the case, but that is what it seems like. I’m pretty sure it’s more like a third, but at any rate, there is a clear difference. 40 miles on a charge, never without throttle assist + heavy throttle use with this amount of power is truly impressive.

In our view, e-bikes are approaching a crossroads in concept and design. Heading off in one direction are longer travel, enduro-style e-bikes, which are largely designed for cruising up and then blasting back down. Plotting a slightly different course is the idea of a lightweight model that rides much more like a normal mountain bike, but requires more work from the rider. Of the two approaches, both have their benefits, but it’s the latter that gets us the most excited. Once the overall weight falls into the 16-17kg range (the lightest bikes are currently19-20kg) it’s going to be really hard to tell the difference between an e-bike and a regular trail bike on the descents and the flat, but you get the benefit of a gentle push up the climbs.
French brand Moustache doesn't take itself too seriously – which shouldn't come as much of a surprise when talking about a brand named after an item of facial hair – but they certainly don’t mess around when it comes to e-bikes. The Samedi 27 Trail is a highly acclaimed steed that comes in a range of price points, but the top-of-the range, carbon-fibre Trail 11, really steals the show. At a snip under £8k, this zippy trail bike features a proprietary (to Moustache) rear shock and carbon rims, both designed specifically for e-MTB. The full carbon frame, with its sleek Bosch PowerPack battery integration, is a work of art.
Power delivery is smooth and easy to predict, once you get the hang of it. We’re not sure if integration is better on the Turbo road bike, or if the slow, technical nature of trail riding just highlights some quirks. The motor shuts off less than a second after you stop pedaling, and the onset of power delivery is momentarily delayed once you begin pedaling. And this did mean we had to adapt our riding style a little bit to deal with that slight lag. 
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.
