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.
China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008,[72] and reaching an estimated fleet of 120 million e-bikes in early 2010.[2][73] This boom was triggered by Chinese local governments' efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities.[72] Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car.[2] Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007.[73] By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.[72][73]

E-bikes use rechargeable batteries and the lighter ones can travel up to 25 to 32 km/h (16 to 20 mph), depending on local laws, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany as of 2013, they are gaining in popularity and taking some market share away from conventional bicycles,[1] while in others, such as China as of 2010, they are replacing fossil fuel-powered mopeds and small motorcycles.[2][3]
I really wanted to love this bike, I've only had it a few days, and it's probably too soon for a review, but I can see some issues with the bike. I'll start with the good, it was here 2 days after I ordered it which was amazingly fast shipping, the bike was easy to assemble, very sturdy and high quality looking and feeling, and even came with a nice tool set for assembly and a bell and water bottle, pretty good saddle, and I was very happy with the price, if it performs as I hope it will. Now the bad, as soon as I get a quarter mile from the house my battery indicator light goes from green to yellow, that is way too soon for the battery on a bike with this alleged range to be at "half life?". I have read in other reviews many have the same issue and say that it is just "inaccurate " and to "not pay attention to that" but it is disconcerting to me. Also the bike does not have the power I was expecting, it is truly a "peddle assist" bike, and not a throttler, the bike basically wants you to peddle and works best as you peddle, in fact the motor actually cuts on and off based on you peddling, in addition to cutting on with throttle, don't get me wrong it will power through on throttle alone on a flat surface pretty well, but if you expect not to do much peddling at all, this is not the bike for you. The fit of the bike isn't great for me, I am 6'2 and the fit for me is a bit awkward, ie: the bike is a bit small for me, anyone my height or taller may want to look at other options, and I can't raise the handle bars at all I don't think, although I believe you can change the angle of them. I've only taken it for 3 short rides as of yet and I was reasonably satisfied with the bikes response and power for my needs on these short trips, but I will have to take a few longer rides before I can give a more complete opinion. The bike is an eye catcher and I see people staring at it everywhere which is cool, I will update as long as I continue to own the bike, but I'm still a bit on the fence about it.
It’s probable that GM was hoping for more press for its announcement of the same day as Musk’s interview going live, that it had actually built and was going to sell a pair of electric bikes. It launched a $10,000 naming contest. The bikes were built in-house by GM, including engineers who had worked on the Bolt. The Director of General Motors Urban Mobility Solutions, Hannah Parish said:
Over several months, our team of four professional mountain bike testers rode each of the electric mountain bikes in our test selection on a variety of trails and terrain in a range of weather conditions. We had each tester ride each of the bikes numerous times, often riding the different models back to back for the sake of comparison. We didn't go easy on them. Instead, we treated them all as if they were our own, putting them all through the wringer to identify their strengths and weaknesses. We scrutinized every aspect of each e-bike's performance and scored them all on several rating metrics, e-bike controls, downhill performance, uphill performance, power output, and distance range. Each metric are described in greater detail below. It is important to note that during our testing our impressions of these e-bikes changed dramatically. Our first impressions didn't exactly stick. It was essential for us to test the different models head-to-head and make direct comparisons to flush out the differences. For example, everyone was initially a little underwhelmed with the Specialized's power and more excited about the Haibike, but after hundreds of miles of testing our impressions changed. We go into more detail on this below.
The Haibike AllMtn line makes an appearance again with this incredible price-point option. The AllMtn 6.0 is a nice option with entry level components but the same aggressive build as the rest of the AllMtn line. And when I say entry level components, I definitely don’t mean that as a negative. You still get 150mm of travel with a Suntour Aion 35 RC suspension fork, a RockShox Deluxe RT rear shock, Magura MT32 hydraulic disc brakes, and Shimano Deore M6000 drivetrain with 20-speeds.
With mountain bikes already sporting hefty price tags, the cost of adding an electric motor might be enough to send the value-conscious rider's head spinning. Fear not! We created the table below to help you sort through which bike has the best performance to price ratio. Bikes that fall lower and further to the right, such as the Top Pick winning Commencal Meta Power Race 650B+ and the Haibike XDURO AllMtn 8.0 represent a relatively great value.
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.
Works well with most Pedego models. Single bike max weight: 60 pounds. Total max weight: 120 pounds. Secure bikes quickly without frame contact with the frame-free ratcheting arm Eliminate bike interference by adjusting side to side to create generous spacing between bike mounts Ideal for carbon frames, mountain, downhill, and fat bikes as it fits […]
The BH EVO High Performance Urban electric bikes incorporate the “TS System” which fully integrates the battery in the frame and was groundbreaking when launched giving rise to a whole new style of eBikes. The Pro model electric pedal assist bikes include a compact and removable central LCD display, and a new ergonomic and highly functional remote control. See the EVO e-bikes...
Functioning as their premier product, the HPC Revolution took over two years and five prototypes to get right. What’s left is a hand-welded electric mountain bike made right here in the United States featuring a 6061-T6 aluminum frame that weighs only 13 pounds and power levels upwards of 6,000W making it capable to reach speeds of 60 mph. You’ll also find its 203mm travel RockShox Boxxer World Cup Fork come in handy while off-roading as well as its Magura MT7 quad piston performance brakes when traveling at close to highway speeds.
E-bikes can also provide a source of exercise for individuals who have trouble exercising for an extended time (due to injury or excessive weight, for example) as the bike can allow the rider to take short breaks from pedaling and also provide confidence to the rider that they'll be able to complete the selected path without becoming too fatigued[58] or without having forced their knee joints too hard (people who need to use their knee joints without wearing them out unnecessarily may in some electric bikes adjust the level of motor assistance according to the terrain). A University of Tennessee study provides evidence that energy expenditure (EE) and oxygen consumption (VO2) for e-bikes are 24% lower than that for conventional bicycles, and 64% lower than for walking. Further, the study notes that the difference between e-bikes and bicycles are most pronounced on the uphill segments.[59] Reaching VO2 Max, can really help your body as a whole[60]. Professor Janet Lord of Birmingham University in the UK published a study that looked at older cyclists, ““The study looked at muscle mass, blood cholesterol, their VO2 Max, lung function, and in many of those measures we found they didn’t age! No loss of muscle, their bones were a little thin (but nothing like the general population), their blood pressure didn’t go up.[61]
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.
With different degrees of assistance at your fingertips, riders of varying fitness levels are easily accommodated on the same ride too. Which, depending on who’s setting the pace, can bring a social aspect back to big days out, because you can all ride together and the assistance from the motor makes it that much easier to string a coherent sentence together even on the steepest climbs.
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.
First of all, you’ll get a RockShox Lyrik RC Boost solo fork with 150mm of travel. You don’t find this fork on many electric mountain bikes at this price point. The new Brose Drive S motor is also featured on this bike. This is great for e-MTBs because it has 5 nm more torque than last year’s Brose bikes. You’ll also get a top-of-the-line derailleur with a Shimano Deore XT 11-speed drivetrain.
One of the primary purposes of an e-bike is transferring power from the motor to the drivetrain to "support" your regular pedal stroke. All of the different motors do this in relatively the same way, although subtle differences in their power output make them all feel slightly different. It is important to note that all of these systems work impressively well, the differences between them are relatively subtle but noticeable. We tested this metric primarily based on feel, as opposed to any sort of scientific measurement, and our testers could all notice the differences between the various models. All of the e-bikes we tested have several support modes offering varying levels of pedal assist support. The Commencal and Specialized models both offer three, the Trek has four, and the HaiBike has five levels of pedal assist support. All four models also have a walk-assist setting which provides up to 3.7 mph of support in the event you have to hike-a-bike to help you push these heavy bikes uphill.

When you are one of the top car manufacturers in the world witnessing an ever-changing landscape of reluctant buyers, what should you do? Ideally, you take scope of what works and phase out what doesn’t. GM’s bold Bolt plan was to offer the electric vehicle (EV) as a personal means of transportation and a shared mobility platform through its Maven program. We haven’t heard much from that initiative and it seems GM is ready to get in bed with the top two ride-hailing companies, Uber and Lyft. Is GM a bit lost in its strategy? Or is it figuring out what works and sharpening its vision?
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...

There are individuals who claim to have lost considerable amounts of weight by using an electric bike.[62] A recent prospective cohort study however found that people using e-bikes have a higher BMI.[63] By making the biking terrain less of an issue, people who wouldn't otherwise consider biking can use the electric assistance when needed and otherwise pedal as they are able.[64] This means people of lower fitness levels or who haven't cycled in many years can start enjoying the many health benefits E-bikes have to offer.

Scott’s top-rung e-MTB is one of the best-looking e-bikes available. Not only that, it’s also kitted out with outstanding components, including Shimano Di2 electronic shifting and Scott’s proprietary TwinLoc remote suspension mode shifter (open/trail/lockout).  Shimano's Steps motor will get you reliably up to speed along the varied trails this bike is made for, while its powerful Zee brakes will slow you down again. Its quality can't be disputed. Other price points available.
Having a motor bolted to the bottom of a mountain bike that provides pedal assistance is an amazing leveller. The constant torque it applies to the chain rounds out the squarest of pedalling actions, which in turn helps stabilizes the rear suspension and counter pedal induced bob, seamlessly shifting your focus from pedalling efficiency to battery life.

E-bikes remain a subject of controversy in mountain biking circles. You may not be able to take one on your favorite singletrack right now, as most non-motorized trails prohibit them. However, things have been tilting in a more permissive direction. Most recently, IMBA, the sport’s largest public advocacy group, shifted its stance to support allowing access for some pedal-assist e-bikes (those that top out at 20 mph) on some trails. With every major manufacturer making e-mountain bikes, more access is likely only a matter of time. “In a few years, people will realize that electric mountain bikes have no more trail impact than a regular mountain bike,” Benjamin says.
In the end, the Specialized Turbo Levo FSR Comp 6Fattie proved to be the tester favorite, offering the best downhill performance that felt the "most like a mountain bike" that the other models couldn't match. The Specialized proved to be the most nimble and agile by far, with the lowest center of gravity, shortest wheelbase, less rear wheel travel, and shortest reach, yet still managed to be confident and stable at speed. By contrast, the Commencal Meta Power Race 650B+, our Top Pick for Aggressive Riders, felt much more one-dimensional with its long and slack geometry and ultra plush suspension, excelling at speed, but sluggish at lower speeds or technical downhill sections. The HaiBike XDURO AllMtn 8.0 proved to be a less inspiring downhill performer, with a massive feel, rattling battery, and a generally unrefined feel, although it was good at going straight and fast. The Trek Powerfly 7 FS was our least favorite e-bike to ride downhill, with a less impressive component specification that held it back and didn't inspire confidence on descents.
The three bikes we tested all use a different e-bike motor system, and the controls, the primary user interface, are an important element that we rated but didn't weight as heavily as some of the others. Each motor system and their associated controls are different. Our primary interest is in how user-friendly is it to interact with the system, how intuitive and ergonomic are the shifters, how good and easy to read is the display, and how easy is it to charge the battery? Each drive system also has a smartphone app that is intended to allow the user to fine-tune the motor's support settings, create custom settings, monitor battery charge and health, and a whole lot more. While we don't feel the apps are necessary for the use of any of these e-MTB's, those with an affinity for technology or personalizing your ride may be inclined to use them.
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.

Generally speaking, e-bikes are bicycles with a battery-powered “assist” that comes via pedaling or, in some cases, a throttle. When you push the pedals on a pedal-assist e-bike, a small motor engages and gives you a boost, so you can zip up hills and cruise over tough terrain without gassing yourself. Called “pedalecs,” they feel just like conventional bikes—but better, says Ed Benjamin, senior managing director at the consulting firm eCycleElectric. “You control your speed with your feet, like with a regular bike,” he says. “You just feel really powerful and accelerate easily.”
On the 8.0 specifically, Haibike sets you up with the brand new Yamaha PW-X motor. This motor comes standard with a 500 watt hour battery, Bluetooth connectivity, and 80 nm of torque out the gate. The PW-X also boasts the benefit of a dual chainring up front. This means you’ll save some battery if you’re willing to work a little harder and use those gears! Speaking of gears, you’ll get a Shimano Deore XT drivetrain. Pair that with Fox 34 Float Performance front suspension and a Fox Float DPS rear shock (150mm travel) and you’ve got a fully-capable, all-around ride.

The final appearance of both the FullSeven and the Yamaha PW-X on the countdown. This top notch 27.5″ wheeled shred sled is another perfect fire road rider for the intermediate rider looking to step their game up. One thing I didn’t mention before but I wanted to let you all know is that I think the FullSeven geometry this year allows the bikes to be more accessible to riders of all sizes. Traditionally, most companies offer one or two options for female riders. Haibike does offer the FullLife models, but the FullSeven series by and large offers better components and a very similar geometry. I think that’s great.
From the tropics to the polar caps, Stark Drive is designed to handle a broad range of temperature conditions with a ruggedized frame and high quality battery pack as well as all terrain tires (standard) or even our fat tire model. Take Stark Drive with you wherever you go. When Designing Stark Drive in Stockholm Sweden we were very conscious of the fact that weather effects battery life on your electric bike so we designed our electric bike with this in mind.
In the pursuit of speed, all trails lead to Camber. We designed it to be the ultimate speed-loving trail bike, which means that having equal efficiency both up and down the trail is an absolute must. To make sure of it, Cambers feature our fully active & independent FSR suspension with our Position-Sensitive Brain technology. So if your rides see you going big and going fast, the Camber is tailor-made for you.
The Moterra is Cannondale’s biggest and baddest e-mtb and just looking at this thing you can see that it’s built to withstand some wicked downhills and big drops. With 130mm of front and rear travel, paired up with 27.5-inch wheels and trail-grabbing 2.8-inch tires, along with a KS LEV Integra Dropper Post make this pedal-assist mountain bike a great option if you want to climb farther to shred longer, but don’t want to lug your bike uphill for ages. The 250w motor, placed slightly farther forward than most other bikes to optimize weight distribution and handling, will give you a nice boost so you can enjoy the ride up and not be too gassed when you get to the top. After all, it’s all about the ride down, right?

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 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. 
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]
