Electric bikes are a green alternative to driving a vehicle. Studies carried out in several towns and cities show that the average car speed in rush hour traffic can dip as low as 18 to 20 mph. Electric bike speed can be as high as 15 mph. With an electric bike, you can reduce pollution, improve fitness, and still arrive at the same time as your car-bound colleagues.
Mountain bikers and their associations (which I used to be a proud member of), should reconsider their anti-eMTB stance, realize there is a need and demand for Type 1 eMTBs, and focus their efforts on keeping trails open for all mountain bikes. Mountain bikers deserve the right to ride more of our public trails than we are currently allowed. I won’t open a can of worms with my strong opinions on where I believe mountain bikes should be allowed, but suffice it to say that we don’t have near enough access as we should.
In the 1890s, electric bicycles were documented within various U.S. patents. For example, on 31 December 1895, Ogden Bolton Jr. was granted U.S. Patent 552,271 for a battery-powered bicycle with "6-pole brush-and-commutator direct current (DC) hub motor mounted in the rear wheel". There were no gears and the motor could draw up to 100 amperes (A) from a 10-volt battery.
While the first functional battery was developed in the year 1800 by Italian physicist Alessandro Volta, a practical battery would not be seen for several decades yet. By the end of the 19th century, practical and portable batteries were more widely available, this finally freeing the electric motor to be used in a wide new array of applications. It might come as a surprise, but the electric motor, battery, and a bicycle were first paired as far back as the 1890s. It would be approximately 100 years later that electric bicycle development finally entered the mainstream, but the technology and concept behind the electric bike were all in place generations ago.
Government agencies like the USDA National Forests and the Bureau of Land Management should distinguish between electric pedal-assist eBikes (Type 1) and self-propelled eBikes (Type 2). The former are still human-powered whereas the latter are fully motorized like a motorcycle. Some states like California are already recognizing the different classifications of eBikes and allowing some on trails while prohibiting others. This clear distinction should help us avoid expanding our mountain bike trails to motorcycles, or worse yet, have trails that are currently open to mountain bikes relegated to “hiking only.”
Last year, the Trek Powerfly 9 LT was one of the only ebikes with geometry and handling that came close to a modern enduro bike. For 2018, Trek has built on that winning formula with new frame. It’s lowered the battery in the downtube, while adding a stiffer Fox 36 fork, more powerful SRAM RE brakes and a stronger Bontrager wheelset. All welcome improvements to a really capable bike. The price has also crept up to reflect the changes. The biggest transformation however, is that Rocky Mountain has raised the ebike bar to a new high with the Altitude Powerplay.
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.
As the CleanTechnica series has been showing, electric bikes are an increasingly big business, and becoming the dominant form of motorized two-wheel transportation globally. The innovation, design, and money is flowing to electric bicycles much more than motorcycles. This is part and parcel of our increasing urbanization and demographic shifts globally. Electric bikes just make sense. They shorten commutes, they flatten hills, they make groceries and children light, they are fun, and they are clean, silent, and convenient.
When all was said and done, the Commencal Meta Power Race 650B+ proved to have everyone's favorite e-bike controls. Commencal uses the Shimano Steps E8000 motor and system which features ergonomic thumb shifters, a small but easy to read digital display and a secure and straightforward charging connection. The ergonomic shifter of the Shimano system is better than the electronic buttons found on both the Specialized, HaiBike and Trek. The Commencal's best-in-the-test digital display also proved to be a favorite for its small size and out of the way mounting location, easy to read at-a-glance information, and color-coded support settings information. The HaiBike's Yamaha PW-X motor and system also featured a digital display, but testers thought it was a little too big, displayed too much information, was more challenging to read, and generally felt a little more clunky and less refined than the Shimano system. That Trek Powerfly's Bosch Purion shifter and display unit was easy to read and had a bright screen, but was in a less visible location on the left side of the handlebar. Our Editor's Choice Award winner, the Specialized Turbo Levo FSR Comp 6Fattie scored the lowest in this rating due to the lack of a handlebar mounted display and a less user-friendly charging connection.
Folding Electric Bikes- These are mostly used when people need to combine different modes of transport. For example, if you need first to take the train or bus, a folding e-bike can be useful to carry along. Also, very short trips are more convenient with these electric bikes, since you don’t need to bother tying them up. Typically, these are very light, even with the motor and battery. At Christmastime, consider this model for urban friends and family who use mass transit to get around.
Cyclocross demands a lot from both bike and rider, and the CruX has been engineered to give the precise and efficient performance needed to win races, and the durability to win them every weekend. The frame's geometry and character has been created with input from some of the world's most accomplished racers, making for an agile, easy-to-shoulder bike that is as fun to ride in a World Cup as it is in the local woods.
A letter from Casey Evans to Electric Bike Technologies, makers of the E-BikeKit™ electric bike conversion kit system. This one of kind adaptive electric stroller was designed by students from California State University-Sacramento using two 500w direct-drive hub motors controlled by a single E-BikeKit system. Thank you for enabling me to take my daughter hiking! My name is Casey Evans and my daughter, Montel, was born with a very rare...
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.
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.

I'm looking to leverage the Cycle to Work Scheme and have been looking around for an e-bike to purchase. I used a lot of the information provided here and have come to the conclusion that the Kreiger from Woosh meets all my needs. 95% of the time the bike will be used to commute to and from work, the rest of the time I'll probably be rising it around the park with the kids. The thing I like about this bike is that it pretty much comes with everything (except the lock) that you'd need to get going. I guess, if I really wanted to, I could upgrade the Bafang motor on this to a BBS02 with a better battery.
Getting an e-bike can dramatically increase how often you ride, according to a recent survey of nearly 1,800 e-bike owners in North America. Beforehand, 55 percent of respondents said they rode daily or weekly. After buying an e-bike, that number soared to 91 percent. It makes sense: Even if you’re super fit, you still get tired (likely from training or racing) and remounting your bike can feel like a chore. If you have an e-bike, you can continue riding while giving your knackered legs a bit of a break. You can also go faster, which makes biking for longer trips more attractive, even when you’re pressed for time.
Every major bike manufacturer—and literally dozens of smaller ones—is already in the e-bike game. Car companies aren’t far behind. Ford is already bankrolling an electric bike-share system in San Francisco, and plenty of others are eyeing up the e-bike market. “The car business is jumping in with both feet,” Benjamin says, “because they realize that cars in high-density urban areas, where more than half the human race lives, just aren’t working anymore.” With big transportation players like Uber looking into e-bikes, and cities searching for ways to relieve traffic congestion, programs may only continue to expand.
We’re an e-bike retailer based in Brooklyn, serving NYC, the rest of the US, and several other countries. Propel grew out of the recognition that e-bikes hold the potential to transform transportation as we know it. We’ve dedicated ourselves to bringing that transformation about since our founding in 2011. We’re pioneering a new industry standard that all the electric bikes we sell must meet, educating legislators so e-bike riders will be treated fairly under the law, and guiding consumers away from expensive pitfalls towards their perfect e-bike match.
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.
Electric Hybrid Bikes- As the name suggests, these bikes combine the properties of mountain and fat-tire bikes. They are built to be fast and tough at the same time. They are lighter than electric mountain bikes, so you don’t have to deal with the excess weight when going up hills. You can use the bike to carry heavy luggage or cycle through rough trails.
Forward-thinking parents are giving up thier SUVs and opting for electric cargo bikes for getting the family around. Cargo bikes are seeing a resurgence in popularity with the rise of electric conversion systems that convert these awesome people movers into family toting electric vehicles. One year ago the Wall Street Journal ran a full page article in their weekend edition entitled The New Station Wagon. Since then the trend for...
Just recently my son came to me with this idea of getting an eBike so we could ride together again. He shared some YouTube videos of guys riding these new bikes on technical terrain I dreamed of doing again. I was intrigued enough to test ride an eBike at a bike shop near my home. The salesperson took me out for a long hilly spin on a dual-suspension demo bike and I was impressed. The motor is adjustable from barely noticeable to seriously helping on the uphills. It doesn’t propel a rider like a motorcycle does, instead it just gives a boost to the rider’s normal pedaling of the bike. This assist mode can be turned off too.
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 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.
E-bikes use rechargeable batteries, electric motors and some form of control. Battery systems in use include sealed lead-acid (SLA), nickel-cadmium (NiCad), nickel-metal hydride (NiMH) or lithium-ion polymer (Li-ion). Batteries vary according to the voltage, total charge capacity (amp hours), weight, the number of charging cycles before performance degrades, and ability to handle over-voltage charging conditions. The energy costs of operating e-bikes are small, but there can be considerable battery replacement costs. The lifespan of a battery pack varies depending on the type of usage. Shallow discharge/recharge cycles will help extend the overall battery life.
