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]


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.

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]

“I can go on Alibaba, buy parts, set up shipments, and get people to buy these things,” she says. “The question comes on the support side. Will they have spare parts? Will they have tech support? Do they carry insurance? Real manufacturers of e-bikes have serious insurance in case something goes haywire or someone has an accident. That’s $20,000 to $30,000 a year.”
Gearing: none (many hub motors, one motor revolution = one wheel revolution), fixed gear reduction for more torque, varies when geared motor drives the chain through the bicycle gears which increases torque about 50% (in low gear) for better hill-climbing and offers better top-end speed (in high gear) than direct drive systems using motors of similar wattage.

Have to give a shout out to a Bulls Brose option. They were the first manufacturers I saw integrate the battery into the frame really well, and they’ve continued to improve upon that design. As I mentioned above, I love the wave frame. Super easy to get on and off and it’s got a cool look as well. If you’re not a fan, this bike does come in both a Diamond and step-thru frame.
Information about the company’s two co-founders is scant. Storm Sondors has left virtually no trail behind him on the Internet, save for a seldom-used YouTube account. Jon Hopp is a film editor working for a Los Angeles marketing firm. His Facebook account displays photos of two fat-tire bikes virtually identical to the Storm eBike, sporting logos from different manufacturers.

Electric bikes are categorized by classes: Class 1 ebikes are pedal-assist cycles with a top speed of 20 mph. (Some localities have banned Class 2 and Class 3 ebikes, which are throttle on demand.) The trick to using a Class 1 bike is to, well, pedal. “If the pedals stop, the bike doesn’t go,” says Saltvold, who describes using an ebike as akin to running on a moving walkway in an airport terminal. Whitaker notes that customers say they switch off the pedal-assist to get more exercise, then turn it back on when going up a hill or wanting to increase their speed.
For the past few months, I’ve been preparing for a trip through Scotland and England. If you’ve read any of my other lifestyle posts, then you know that I think the absolute best way to explore an area is by bicycle. So, when I was planning my trip, of course I decided to do an electric bike tour. I’ll be doing a John O’ Groats to Land’s End ride, approximately 900 miles. Let’s talk about the best electric bikes for bike touring.

Using an electric bike for long-distance touring has its pros and cons. The motor will help carry the extra weight of your kit, particularly on the hills, but you have the added hassle of having to charge the battery every night. You’ll want a powerful motor and a good battery, though if you’re fully loaded, don’t expect to achieve the maximum advertised range.

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.
All Kalkhoff bikes come with lots of extras: hub or motor powered front and rear lights, bells, fenders, chain guards and racks. Some include a built-in quick-lock or a rack-mounted pump. There are a number of features available for the discerning cyclist, whether it's the Magura hydraulic brakes, the B&M super-bright hub-powered headlight, the top-of-the-line Shimano internal hub or derailleurs or the three-layer powder-coated paint process.
We spent 45 hours on research, videography, and editing, to review the top choices for this wiki. With rechargeable battery-powered pedaling assistance, electric bicycles offer an increasingly viable alternative to fossil-fueled commuting, and e-bikes enable riders of various abilities to extend their range. But the street-legality of these hybrid machines remains a contentious issue, so be sure to check current state and local laws governing their operation before you hit the road.

We found the Groove motor a little laggy in engagement, with often almost a full rotation of the cranks before the assist engaged - compared with the Gazelle and Vanmoof, the pick-up was frustrating. Putting our issues with the assist to one side, we couldn’t fault the aesthetic: we loves the semi-mixte frame style, a practical non-gender specific design.
You should also think about how much gear you are going to need to carry. The reason this will affect your decision is because some electric bikes don’t have the capability to mount a front rack while others do. Plan on doing a 3-day trip? You could probably get away with just a rear rack. My advice though would to be to purchase an electric bike with the capability to mount a front rack as well. This way, if you decide to plan a longer trip in the future, you can simply buy a rack and be on your way instead of potentially having to buy a new bike.
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...

Electric bikes or ebikes, widely popular in Europe and China, are steadily making their ascent in the U.S. bike market. Erik Saltvold, founder and owner of ERIK’s Bike Shop, a Midwest-based chain for bike sales and repairs, says the ebike is the fastest-growing specialty bike in the industry. Last October, market research company NPD Group reported that electric bike sales had grown 95 percent in the 12 months ending in July 2017, with sales totaling nearly $65 million.

Over the years our lineup has grown, and as a result, the offering has become more complicated than it needs to be. Specifically, this year we introduced a 500w geared motor option to the lineup and that has created some redundancy. Before outlining changes, we would like to ensure everyone that we will be stocking enough inventory of previously sold parts for a long enough time to ensure all warranties...
If you’re looking for a premium option, this might be the bike for you. I’ve got to say that I don’t think there is a more comfortable commuter than this. Full suspension, upright positioning, and plus sized tires keep things nice and smooth. But the real reason this beast makes the list is the dual battery. Love it. The other day I realized we only had about 10% of the battery left in the charge. It was going out for a test ride, and I was like “dang gotta charge it” but then I was like “lol no I don’t 10% means there is like 15 miles left, BOOYAKASHA!”

The Dash is an excellent, low-cost option for those looking for an intro to e-bikes kind of ride. The TranzX motor will take you up to 28mph for about 16-35 miles per charge–more if you’re conservative with the assist. The components aren’t too shabby either. Shimano M365 hydraulic disc brakes keep you safe, the Shimano Deore SGS drivetrain, and RockShox Paragon fork with 65mm of travel make it a great entry level option.


This is the Freway Buffalo. It’s an ebike. I couldn’t say no to a free ebike to play around on, so we’re gonna have some fun with this thing for sure. It’s not a high end ebike like the Specialized Turbo Levo, but it only costs 1700 bucks whereas the Turbo Levo costs as much as a car. Although it’s marketed as a mountain bike, I’d put it in the commuter category. It’s got a big cushy seat, a really long stem, and those antler things on the handlebars. I’m not obligated to give you guys anything but the truth, so let’s put this thing together and take an objective look at it. First, let’s cruise on over to Freway’s website.

China's experience, as the leading e-bike world market, has raised concerns about road traffic safety and several cities have considered banning them from bicycle lanes.[2] As the number of e-bikes increased and more powerful motors are used, capable of reaching up to 30 miles per hour (48 km/h), the number of traffic accidents have risen significantly in China. E-bike riders are more likely than a car driver to be killed or injured in a collision, and because e-bikers use conventional bicycle lanes they mix with slower-moving bicycles and pedestrians, increasing the risk of traffic collisions.[2]
With asthma, the commuter was just what I needed to get up these hills in the DC area without having an attack. With the 20 miles range, that gets me though my day, I can almost get about 35 miles in, since I only use the assist for hills, and I call any incline a hill. It came in two days, was very easy to install. I did it myself. It took me over an hour because I was scared, and watch the video over and over. Before I install this, I never did any work on my bike, not even changed a flat. When I do group rides, people notice that I'm no longer the last person up the hills and tell me to slow down! They are impressed that I was able to installed it myself. I brought this in Feb. 2017, had one problem with the on/off switch which customer service addressed, sent me a new switch and instructed me on how to install it myself. They actually sent two switches, other than that, I had no problems with it. Great customer service that stands behind their product, great product, equals happy customer.

“At $500 apiece,” he says, “the company would be selling e-bikes at a loss, once they factored in product liability insurance, quality control, regulatory compliance, safety testing, and post-sales service and support. Chinese e-bikes could certainly ‘leak’ into the U.S. market near that cost, be sold as a loss leader, or be marketed directly on eBay, but a fully costed business model could potentially lose up to $250 per bike.”
One reason for doing so is the way it is powered, which works in a manner that would be familiar to someone accustomed to a manual transmission car. Like a car, you start in a low gear and work your way up as you gain speed. Since the motor runs through your transmission as opposed to applying power directly to the axle, the gear you’re in really matters. The importance of gearing connects you much more to the road and the terrain, which means you are a more active rider than when using throttle-controlled electric bikes.
Depending on local laws, many e-bikes (e.g., pedelecs) are legally classified as bicycles rather than mopeds or motorcycles. This exempts them from the more stringent laws regarding the certification and operation of more powerful two-wheelers which are often classed as electric motorcycles. E-bikes can also be defined separately and treated under distinct Electric bicycle laws.
Comfort. Like any other type of bike the electric bike should offer you a comfortable ride. All general components such as, saddle, handlebars, the geometry of the frame should put you in a comfortable position. If the bike doesn’t satisfy these criteria it’s certainly not the best electric bike on the market. After all you’re going to spend quite a lot of time riding it, so you might as well look for a more comfortable solution.

I tested the Sduro 8.0 towards the end of last year (there's a new range out for 2018) and was surprised by its nimbleness. You expect e-bikes to be less maneuverable than their acoustic predecessors, but, pelting down some bespoke forest paths near Pedal & Spoke in the Surrey hills, I found I completely forgot that there was a box of electronic EPO on my frame. Partly, that's because the battery is cleverly integrated into the frame to decrease drag; mostly, it's because the suspension is soft and the steering nimble, much like a normal mountain bike.
The G-10 features a top-tube mounted on-off button and ‘set’ button for one of four power modes, all linked to a Groove Go wheel mounted motor via a removable clip-lock battery stashed under the down-tube. Kalkhoff has paired this with a mid-range Shimano Tiagra 1x10 speed drive-train and effective Shimano M396 hydraulic disc brakes. A nice touch is the anti-slip ‘grip-tape’-covered flat pedals, perfect for a bike to be ridden around town without specialist shoes.
In response to customer questions about the display, we posted a video detailing the basic setup of the LCD during installation of the kit. You will need to adjust the settings for the motor type, wheel size, and battery voltage in order to match your specific kit.  Detailed instructions are available in the E-BikeKit manual, E-TrikeKit manual and LCD Quickstart Guide

Kalkhoff enjoys an enviable reputation by virtue of a long and revered history based upon obsessive craftsmanship and insistence upon only the most indestructible and ecologically attuned processes, materials and components, together with the most stunning and intuitive technologies available.
