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.

Focus manage to offer both one of the lightest all-mountain capable e-MTBs and also one of the greatest battery ranges. How do they do it? Simple. A smaller-than-most, 378Wh battery is integrated into the frame (the other bikes in this list feature a battery around 500Wh). Another, optional, 378Wh battery also attaches externally within the mainframe. It’s a novel idea, and the bike is noticeably more playful than some others in its lightweight guise. 


My left crank arm came loose and seems to have damaged the square bottom bracket mount. I assumed the bottom bracket was just a standard square taper, but noticed it says “8fun” on it. However, I can’t seem to find an 8fun bottom bracket available online, so I can’t figure out what part I need—I suspect there is a something obvious that I’m missing. Any ideas to get me back on the road? Thanks all.
The extra grip a 50lb e-bike normally helps to prevent overshooting corners when on the brakes, and bring pure DH-bike-like fun factor on the steepest trails. This electric Orange, however, rides more like a ‘standard’ enduro bike with a motor, which could be good or bad, depending on your expectations and riding style. It’s built tough and delivers stacks of fun in less time than any regular bike can. Adding a motor hasn’t upset Orange’s superb geometry.
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.
It's what's inside your motor that sets it apart from the rest. Quality parts and assembly We've written here before about how to choose a motor, the different types of motors, the performance differences between motors, etc. But today I want to show you what makes our motors different from other hub motors. Today, harry is replacing the axle on a customer's direct-drive motor. The bike was crashed and the...
Aluminium alloy frames and downtube mounted batteries with integrated motors provide a budget friendly introduction to these motor-assisted bikes, allowing riders who would struggle to keep up to enjoy the stamina of the pros. For those hard hitters, fully integrated battery and motors combine with lightweight alloy and carbon frames to deliver a ride that’ll take on the most demanding trails.
Haibike ships the HardNine with 29-inch tires, 180-millimeter hydraulic disc brakes, a 100-millimeter front suspension fork, and a nine-speed Shimano shifting system. The bike’s LCD readout is affixed to the handlebars and displays the current speed, level of charge, remaining range, and current pedal assist mode. The company says the battery can be completely recharged in just four hours, minimizing downtime between rides.

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.


Assembly was pretty simple and straightforward, there are some videos online explaining it. Definitely important to know how to switch it on, though -- pressing the "M" button for two seconds with the key in the "on" position. Despite being a heavy bike, it's very quick and nimble. I ride about 15 miles per day and was able to get two trips out of it before charging, riding fast. My only complaints are the squeaky brakes, and the front fender. Said fender is a bit too close to the tire on the front wheel and doesn't mount very securely, so it kept making very loud noises as it would catch the tire whenever I went over a bump or had to brake hard. I just took it off for the time being.
Even if you’re in excellent shape and very fit, you still can get exercise by e-biking. When I did a head-to-head comparison of commuting with my cross bike versus a recreational e-bike, I found that my relative effort was much lower, and I burned about half as many calories, on the e-bike. But I still burned something—up to 200 calories per hour, the equivalent of what you burn by walking. And I opted for quick e-bike rides to town where I would usually drive, which means I was considerably more active overall.
Not all e-bikes take the form of conventional push-bikes with an incorporated motor, such as the Cytronex bicycles which use a small battery disguised as a water bottle.[44][45] Some are designed to take the appearance of low capacity motorcycles, but smaller in size and consisting of an electric motor rather than a petrol engine. For example, the Sakura e-bike incorporates a 200 W motor found on standard e-bikes, but also includes plastic cladding, front and rear lights, and a speedometer. It is styled as a modern moped, and is often mistaken for one.[citation needed]

Our high performance electric bikes offer high power, predictable handling and near silent operation.  If your rides take you up steep single track trails or you just want a bike as light weight as possible, a mid drive system will offer the best hill climbing performance, lighter weight, and better weight distribution.  A hub motor system will offer the most reliable day in and day out operation, faster speeds, more power, and is a better overall platform for everyday commuting.

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]

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.
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.

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.
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.

Stark Drive has always included a front head light by default at no charge for safety with the rear brake light being optional for those who needed this. Now we have reconfigured the homepage so that the rear headlight options i clearly visible and availble without needing to compllicate matters by adding it from our accessories page. We highly recommend a rear brake light no matter what motor you choose for Stark Drive.
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.
In 2012, two e-bike advocates completed the first 4,000-mile (6,400 km) transcontinental e-bike tour from New York to San Francisco to advocate for e-bikes in major cities across the U.S.[81] Pedego Electric Bikes is the best selling brand in the U.S. Many e-bikes in the United States are standard bicycles converted using a kit. In general, the kits include the motor (the majority of which are hub motors built into the front or rear wheel), a speed controller, throttle (usually twist-grip or thumb throttle), necessary wiring and connectors, and a battery. Several U.S. companies offer conversion kits which also offer advanced lithium battery packs. Major manufacturers also offer complete e-bikes. Trek offers a line of e-bikes using the Bionx system in which the rider programs the controller to determine how much effort the motor will give in response to rider effort, from 25% up to 200% of the rider's power. This system ensures a minimum level of rider participation and is also used to comply with many European laws mandating partial human effort before the motor engages.
The box looked rough. Lots of little digs and dents. When I opened the box, the contents were very well packed. Mine did show that it took a good hit to the headset stem as the spacers where shoved and the clear tape was all bunched up and the one spacer was almost at the edge. After taking the tape off, cleaning all the tape residue off everything went together super easy. I used the included multi tool to do most of the assembly. I just needed a wrench for the peddles.
Before this test we thought more travel on an e-bike would obviously be better. After all, with the motor flattening out the climbs, why not have the extra suspension firepower to smooth out the descents? Sounds reasonable, doesn’t it? But in the case of the Specialized Turbo Kenevo Expert, the extra travel and weight make the bike less effective and less engaging on all but full-on downhill tracks. And if that’s your bread and butter, the Kenevo could well be the perfect topping. Here in the UK though, the Vitus proved more versatile, just as capable and way better value.

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.[5]
