Sleek, powerful, and modern. If those characteristics strike a chord for you then the Bulls E-Core bike could be the pick of the litter so to speak. Each handsome yet power-infused ride is assisted by Shimano’s new 250W E-8000 eMTB motor alongside a 375Wh power pack. Thanks to this power plant, this sweet ride boasts enough juice and torque to conquer and climb even the toughest of trails. Additional features include a 180mm front RockShox Lyrik, a rear Fox Float X2 Air suspension to smooth out that descent, Di2 XT electronic shifting, and 203mm Shimano XT hydraulic disc brakes.
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]
REBEL electric bikes powered by the Yamaha central motor create Dynamic and Responsive Power. It also enables the use of a conventional groupset and offers no resistance in «no assistance» mode. The eMTB bikes range have an “External DT System” battery, located in the front triangle and integrated with the design of the frame. The relative position of the less lightweight parts of the system (motor and battery) enables a low center of gravity, guaranteeing a reactive and stable ebike. See the REBEL electric bike models...
My second e-bike, and it is amazing. 40 miles range on full assist, 4 levels of torque sensor assist, one level cadence sensor assist, one level throttle only, 20 speed, forks have 120mm of range, and the 500 watt battery is very powerful. The seat was too hard, so I replaced it with a gel seat and installed a BodyFloat under the seat. Also installed a rack.
The time or distance an electric bike battery will run between chargings is impossible to judge with much accuracy. There are too many variables: terrain, speed, rider weight, bike load (shopping, kids, luggage), and more. However, we can make a few generalizations about an e-bike’s recharge time and overall working life. These generalizations should be used for comparison purposes only.
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...
Upper Dublin Township in Pennsylvania is initiating a pilot project to gauge the advantages of using electric bicycles. The e-bike, as they are more commonly known, will be used for police work and for the Township’s Sitewatch program, which patrols and monitors parkland and playing fields. The people behind the program believe the electric bike could prove to be a useful tool, giving police officers and parks personnel a clean,...
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.

However, if your friends are riding a bigger single battery pack, you’ll have to either choose to cut the ride short or conserve battery life while they run in turbo. If your local rides are short, fast blasts but you want to benefit from the ability to take on longer tours, the Sam2 could be for you. We love the Pro version, but it’s also available at a range of price points.
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.
After you decide which style of e-bike you want, consider the class. In the US, there are three classes defined by the type of assist and how fast the motor will propel you. Most electric bikes sold are class 1 or 3. Class 1 bikes have a motor (max 750w) that assists while you're pedaling, up to 20 mph. Class 3, also known as “speed pedelec” can also have up to a 750w motor, but it can assist you up to 28mph. Both of those are allowed in most states and cities without license. Class 2 have throttles that don't require you to pedal to get a boost. They're allowed on most streets, bike lanes, and paths, but less popular than the other classes and not covered much here (because we still love to pedal and the greater distances pedal assist bikes can cover).
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.
As a serious,but aging cyclist, have been considering the purchase of an electric assist bike for some years. My primary concern was that the bike needed to provide enough power to assist me to tackle some very steep hills and my weight is near 220 lbs. Having no experience with electric assist, I anticipated the 500 watt motor rating of this ... full review

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.

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.
E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque and others are quieter. But generally all four make good options. Look for motor output (in watts) which will give you an idea of total power. But watt hours (Wh) is perhaps a better figure to use—it takes into account battery output and life to give a truer reflection of power.
You can’t really get a cheap e-bike just yet. But if you keep the car in the garage more often, you’ll save cash on maintenance and gas money. Not to mention the added health benefits and potentially fewer sick days from getting more exercise. Prices vary widely, but you should expect to pay at least $1,500 for a decent e-bike, and considerably more ($2,500-$5,500) for a quality bike with a motor system from a major manufacturer like Bosch, Shimano, or Yamaha.
Mountain electric bikes can even be used for commuting to work or going to the grocery store.  When choosing a mountain eBike, make sure that you pick one that has at least 500 to 750 watts of power. Having a powerful motor to assist you on the trail will keep your legs from being sore at the end of the day. This will ensure that you get the most out of your bike and be able to drive across rocks and logs with ease. 
Enjoy the thrill of the ride without the struggle. Although it looks just like a normal mountain bike, as soon as you pedal you will feel the difference. The Gtech Mountain eBilke has an easy to read LCD display, to tell you exactly how much charge you’ve got remaining. Ride for up to 30 miles on a single charge. For adventurous riders tackling more challenging conditions, the range may be reduced to 10 miles per charge**.

Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.
This is list of the best performing, best value electric bikes for 2017 / 2018.

What does this mean for anyone with Stark Drive that was backed with greater then a 250W motor? Quite simply, it means that as long as you have not modified Stark Drive in any way, and depending on your local countries regulations (if they differe with this EU Standard) you are now able to use your bike legally in your location no matter where you are in the EU.
It was a close battle and the Specialized Turbo Levo FSR Comp 6Fattie emerged as the winner of our Editor's Choice Award. Our testers universally agreed that it was the most well-rounded performer on the trail and offered a ride that felt the "most like a mountain bike" of the models tested. It was versatile, with a lighter and more nimble feel, yet it still managed to maintain its charging chops and stability at speed. Specialized has done a wonderful job designing their Turbo Levo models with the battery and motor cleanly and stealthily integrated into the frame. The Specialized 1.3 motor also runs so quietly that you'd almost forget you were riding an e-bike if it weren't for all that power. The Turbo Levo FSR Comp 6Fattie wasn't the most powerful e-MTB we tested, but it used its power efficiently and had an impressive distance range that bested some of the competition by 15% or more in our head to head range testing.
You should be extra aware about your local regulations as in many countries an L1e-A certified bike needs to be registered and insured (be sure to consult your local laws and rules) and with registration comes the security that the bike can be tracked if it is stolen or misplaced. This approval that we have received is European Union wide and even those countries that are not part of the EU but rather EEA do adopt similar regulations in order to keep the market common but you will need to consult with your authorities. We will detail more about the registration process in an upcoming blog post but if you have any questions you can email us and we will respond in kind.
Electric mountain bikes have garnered a lot of attention for their ability to help riders go higher, further, and faster on the trail. As a result, there have been some impressive new eMTB models to hit the market in recent years, making it easier than ever to head off-road. Our favorite is the Haibike SDURO HardNine, which comes equipped with a 350-watt Bosch Performance CX drive and a 500 watt-hour battery. This gives it a range of up to 70 miles, along with a top speed of 20 mph, which is plenty fast on singletrack.

It’s hard to ignore the growing popularity of electric bikes. Commuters and hybrid riders have already embraced the technology, but what about when it comes to mountain shredders? MTB fans are certainly beginning to realise the benefits of electric – an electric mountain bike can give you all the thrills you want from a normal MTB but with the extra power you need to get back to the top and give the trail another go.
What could very well be the newest frontier of all-electric transportation, electric mountain bikes are by no means non-confrontational. On the contrary, they’re also hailed as great power assisted means to conquer those tough to nearly impossible trails you’ve been trying effortlessly to tackle. Which, after all, isn’t necessarily a bad thing. Unless, of course, you’re a die-hard analog fan who only believes those with true grit and dedication should be attempting the most impossible of backcountry trails.

In addition, Kalk weighs under 155 pounds — less than half of traditional motorbikes. Cake customized parts of the drivetrain and implemented an interior permanent magnet (IPM) motor. On a single charge, the bike travels up to 50 miles and as a bonus feature, maintenance is minimal due to the fact there are few moving parts thanks to its lack of a combustion engine.
“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.”
Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.[43]
