Propel started in a small, second floor office with a motivating belief that electric bikes would change people’s lives, and they have. Since 2011, we have been closely listening to our customer’s needs, spent countless hours traveling and researching to learn more about ebike technology as it evolves, and we are advocating for changes in policy that promote a more equitable stake for electric bicycles in the world of transportation. Join us in this movement towards a more sustainable future; together, let’s change the way we move.
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.
A representative for another large international bicycle company informed me that his company is now shifting its production of their 2019 electric bicycle models to two other Southeast Asian countries to avoid the import tariffs on Chinese e-bikes. The source spoke on condition of anonymity as he was not authorized to speak publicly on the matter.
The other thing to consider is that this is a Kickstarter project, so you aren’t directly purchasing from the company, but rather “backing the project” in exchange for a bike. Technically, Stark Drive, or any Kickstarter creator, could cut and run with the money, leaving their backers without legal recourse. In this case though, Stark Drive has already run a successful crowdfunding campaign for their previous bike and demonstrated their ability to deliver, so this is probably at least somewhat safer than a brand new Kickstarter start-up.
Riese & Müller have built their bikes to be masters of bike touring. They are some of the only electric bikes that offer a dual battery setup. This means that you are going to be able to go double the distance without recharging. This capability is truly invaluable during a bike tour. On Bosch motors, this takes you from 500 watt hours to 1000 watt hours. There are not any motors offering that type of battery range.
Both land management regulators and mountain bike trail access advocates have argued for bans of electric bicycles on outdoor trails that are accessible to mountain bikes, citing potential safety hazards as well as the potential for electric bikes to damage trails. A study conducted by the International Mountain Bicycling Association, however, found that the physical impacts of low-powered pedal-assist electric mountain bikes may be similar to traditional mountain bikes.[68]

Sometimes space comes at the most premium of commodities and the Tern Vektron offers a space-saving folding option. At about $3,400, the sturdy folding joints include a magnet and rubber strap to keep the bike folded. The quick-release pedals (wheels release too) help with storage of a bike that doesn’t give up power with a 20-mph speed that can range over 60 miles. But the best part is placing two in the trunk of a car.
Though aside from the extra battery and abundance of included accessories, Riese and Muller’s use of a Gate’s belt drive means no shifting of gears, no greasy maintenance, and much higher durability. If you have the money to spend, Riese and Muller’s Delite nuvinci is one of the best on the market and an ebike we just couldn’t get enough of during our own tests.
Electric Bike Parts, what fits my older electric bike? What can I modify to fit my bike? A brief overview of what electric bike parts do, and how generic electric bike parts can be adapted to your bike. The Plugs, Wires & Connectors Hardly a day goes by without a call that goes about like this; "I have a (whatever) electric bike that I used to ride 6 years ago....

Introducing the future of performance and comfort, the Kinekt BodyFloat seatpost. The innovation isolation system, designed here in Washington, greatly enhances the endurance and enjoyment of riding a bike. Engineered to be infinitely tunable to fit your personal riding style and weight, Seattle Electric Bike is proud to offer this breakthrough seatpost for all your biking adventures.


Another independent e-bike dealership, Adam Solar Rides in Pittsburgh, Pennsylvania, is also feeling the crunch. With essentially zero low-cost electric bicycle manufacturers in the US, Adam Solar Rides imports their entire lineup of electric bicycles from abroad, mostly from China. Like many small businesses owners, they are left with questions about how exactly the unclear tariffs might affect them and other e-bike dealers.


We're gald to announce that we finally released the new 1500W BEST system. The new motor has been possible thanks to the manual winding which offer enhanced performance. With a top speed of 60km/h on a standard 27.5" mountain bike, a torque of 150Nm, and a maximum power of 2200W ( with the 48V battery) the BEST 1500 sets new standards for high performance ebikes. It's possible to buy just the motor and controller, and combine them with a custom battery up to 72V for a maximum power of over 2800W. In addition to that, the system has the full connectivity with the Smartbox module: by your smartphone you can change the motor settings to match your daily needs.  Beyond the Limits.
We ran the C330 almost entirely in its speediest Turbo setting, switching back to Eco or Tour in heavy traffic for a more predictable assistance weaving between cars. Crucially, the display also displays how much assistance you’re getting as well as your speed, trip distance, etc. We used this to ease-back effort and stay in a light power sweet-spot, arriving at WIRED’s HQ without breaking a sweat.
The Patriot DreamE results from the combination of the popular Day 6 bicycle with the Kinetic8-Fun mid-drive motor kit. The unique Day 6 styling eliminates leaning forward, so you sit perfectly upright. That means there is no more stress on wrists, neck, back, and crotch. It also means a superior breathing position and a better way to enjoy the scenery. The step-through design makes for easy mounts and dismounts, while the low seat allows the rider to reach the ground with both feet for stability and safety.

The two most common types of hub motors used in electric bicycles are brushed and brushless. Many configurations are available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design. The motor is built into the wheel hub itself, and the stator fixed solidly to the axle, and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.

The Netherlands has a fleet of 18 million bicycles.[77] E-bikes have reached a market share of 10% by 2009, as e-bikes sales quadrupled from 40,000 units to 153,000 between 2006 and 2009,[78] and the electric-powered models represented 25% of the total bicycle sales revenue in that year.[77] By early 2010 one in every eight bicycles sold in the country is electric-powered despite the fact that on average an e-bike is three times more expensive than a regular bicycle.[73][78]
On a trip to Palo Alto last year, we had the chance to ride Specialized’s pedal-assisted Turbo Vado and the model is still our favorite ebike on the market. Utilizing a 350-watt motor and 604-watt-hour lithium-ion battery, the Turbo Vado is capable of traveling a whopping 80 miles on a single charge, which should be more than enough for any daily commute with plenty of miles left over.
Kalkhoff's electric-assist bicycles start with the same high-quality, sleekly designed bikes that Kalkhoff has been developing for 90 years. A state-of-the-art, brushless, centrally-located motor provides a smooth, predictable power-assist directly to the drive train. Kalkhoff e-bikes come fully-equipped with a variety of features to ensure that your commute, shopping trip, or outing is safe, comfortable and fun.
Ironically, not only would a US e-bike manufacturer need to import the raw materials for their frames, but they could still be subject to import tariffs that the Trump administration has placed on imported steel and aluminum from China. Thus, the e-bikes could end up even more expensive than just US-built e-bikes, as customers would also have to pay for the higher cost of the imported raw materials.
Yes, there are less expensive ebikes on the market but most come with a few serious caveats. The Espin Sport delivers on the full promise of an electric bike, but in a more affordable fashion. This bike isn’t going to tow you around for a 60-mile round-trip endeavor but those seeking their first ebike will get plenty of return on their investment with this model.
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.

Automated Transit Networks (ATN), and the small-vehicle subset of Personal Rapid Transit (PRT), are emerging technologies that can help solve the related problems of congestion, dependence on foreign oil, and planetary climate disruption. ATN/PRT offers clean, quiet, responsive public transit with automated non-stop service available 24 hours a day. In addition to these service benefits, PRT costs far less to build and operate than other transit options ¯ and is safer than walking and cycling on nearby busy streets.
Everyone seems to know a lot about Haibike’s e-MTBs, but I think their commuting and touring bikes are just as good, if a little bit underrated by the e-bike community. Another bike with the Bosch speed motor, this bike is quick and powerful. I really like the spec upgrades on this bike from the Trekking speed model in 2017. You’ve got Magura MT4 hydraulic disc brakes, a Shimano Deore XT M8000 Shadow Plus drivetrain, and the headlight and taillight run off a dynamo.
All three road bikes receive their power from Yamaha’s PWSeries SE motor that comes with four levels of support: ECO+, ECO, STANDARD, and HIGH. The mid-drive motor supplies a maximum of 70 Nm (52 ft-lbs) of torque and cadence support up to 110 rpm. The motors are designed to provide assistance up to 20 mph (32 km/h). Any faster, and it’s all you providing the power.
The other thing to consider is that this is a Kickstarter project, so you aren’t directly purchasing from the company, but rather “backing the project” in exchange for a bike. Technically, Stark Drive, or any Kickstarter creator, could cut and run with the money, leaving their backers without legal recourse. In this case though, Stark Drive has already run a successful crowdfunding campaign for their previous bike and demonstrated their ability to deliver, so this is probably at least somewhat safer than a brand new Kickstarter start-up.

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]
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...
The frame itself incorporates a series of mounts allowing you to easily trick-out the Road E+1 with a rack, fenders, or panniers to more aptly meet your touring requirements. Again, most touring purists will certainly scoff at the mere notion of pedal-assistance, however, individuals looking for more of a guided tour and less of a tour de force will swoon over the Road E+1.
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.

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.
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.
Motor: We have a blog post showing some motor differences: https://www.ebikekit.com/blogs/news/its-whats-inside-your-motor-that-counts Cabling is probably the #1 issue when something goes wrong. Good connectors, good cables, and good assembly (bike shop!) are crucial Strain reliefs on all cable joints! Where you have a junction box or a connector, the stress is concentrated over a small area near this stiff spot on the cable. This can cause small breaks on the internal...
Though aside from the extra battery and abundance of included accessories, Riese and Muller’s use of a Gate’s belt drive means no shifting of gears, no greasy maintenance, and much higher durability. If you have the money to spend, Riese and Muller’s Delite nuvinci is one of the best on the market and an ebike we just couldn’t get enough of during our own tests.

Riese & Muller’s Nevo line definitely tops my list for commuting electric bikes. These bikes are premium, custom made bikes for a reasonable, middle-of-the-road price. All Riese & Muller bikes are hand made in Germany exactly to your specifications. The Nevo line specifically is incredibly well balanced and keeps riders in a comfortable, upright position. Riders also get a suspension seatpost (either the Cane Creek Thudbuster or Satori Elegance LT), which is a nice compromise between the full suspension Homage line and a complete hardtail.

Electric Bike Technologies has been delivering the best experience in electric bike kit conversion since the company was founded in 2008. Driven by a respected founder and a team of dedicated electric bike enthusiasts, the E-BikeKit™ electric bike conversion systems have been sold worldwide to thousands of electric bike riders and fostered partnerships with some of the best brands in the bicycle industry. The company has been featured on NBC’s Good Morning America and the E-BikeKit system is the only electric bike kit system distributed by J&B Importers, the largest bicycle distributor in the United States.
Featuring Bosch’s newest CX Drive motor, the Trekking has enormous torque (that equals acceleration) compared with the rest of the bikes on test. From a standing start the Haibike reaches the 15.5mph European speed limit in seconds. Pair this with mid-sized 27.5in wheels and laid-back mountain-bike geometry, and you have a grin-inducing almost motorbike-like riding experience. This is accentuated off-road, where a rider’s lower average speed is under the motor cut-off point for more of the time, so suddenly the hefty Trekking makes complete sense.
We Can Build It.   Built by hand in Pennsylvania, mostly by Harry and Alec. Custom Wheelbuilding Some people don't know that we build every one of our wheels here by hand in Pennsylvania. This lets us control each step of the process, ensuring that the spokes are uniform, straight, and undamaged, allowing us to apply spoke-prep to the spokes, oil to the nipple seats, and inspect the rims before...
The Cyrusher doesn’t have the reliable Bosch motor that higher-end bikes sport and the Samsung battery is only good for around 500 recharges, which is less than you’d expect for a lithium battery. But with the low price point, there are bound to be some compromises. A great option if you want a decent, all-around model for easy trails or commuting.
Probably the most important thing to consider when researching the best electric touring bike for you is how far you need your bike to take you every day. Be realistic about this. If you purchase a lower end electric bike, don’t be surprised when it only takes you half as far as you want to go. Think about whether or not there are going to be opportunities to charge your battery in the middle of your daily riding. If not, it might be a good idea to buy an extra battery.
Designed for riding around town, this pedal-assist bike has four levels of electric assistance – Eco, Tour, Sport and Turbo – and a maximum assisted speed of 20 miles per hour. This is a well designed and engineered bike, with Shimano Nexus components and a Bosch Performance electric-assist mid-drive system. Front and rear lights are included, and you can even use the battery to charge your smartphone. The integrated ring-lock will help deter would-be thieves, but it’s always best to back this up with a dedicated bike lock.
The frame itself incorporates a series of mounts allowing you to easily trick-out the Road E+1 with a rack, fenders, or panniers to more aptly meet your touring requirements. Again, most touring purists will certainly scoff at the mere notion of pedal-assistance, however, individuals looking for more of a guided tour and less of a tour de force will swoon over the Road E+1.
Another reason I chose the Lacuba Evo E8 is because of its overall geometry. First, check out the upright position you’ll be riding in. This positioning is ideal for bike touring because you’ll be traveling long distances. You’ll be much more comfortable in this position than you probably would be hunched over a road or hybrid bike. I also love how the Brose battery integrates completely into the downtube. Not only does this hide the fact that you’re getting a little extra help (if you’re self-conscious about that), but it also leaves you space to mount water bottle cages, a frame pump, or even a frame-mounted bag. These are sometimes crucial items during a bicycle tour, and many electric bikes cannot accommodate these due to the protrusion caused by a battery.
With over a decade of experience as an advertising executive, Mark is certain that the market will accept the electric bike and is here to make sure it happens. Mark has an impressive list of former clients in industries like pharmaceuticals, convenience stores, community banks, floor coverings, visitors’ bureaus, resorts and Location Based Services (LBS). When he’s not on Facebook, tweeting or learning how to leverage the latest viral marketing techniques,...
However, Emu sells a little foldable number if that's your bag. The Emu Crossbar is for  town commuters that require a sweet ride that's backed up by solid Shimano Nexus hub gears and Tektro brakes, which are adequate if not the best on the market. Riding is smooth and easy, with the crank moving sensor doing its best to iron out any gaps in power delivery.
“First, Taiwan and China have been building almost all the bikes for the entire world for the past 30-40 years. They have ecosystems and two generations of tradesmen that result in the best bikes in the world. Look at all the top brands—Giant, Specialized, Cannondale— they all make their top end bikes in China and Taiwan. Even look at the Italian brands and you’ll see they build their frames in China and Taiwan and paint them in Italy.”

Most consumers want an e-bike that will accommodate its motor without being too cumbersome and will remain stable in spite of its electronic components. Some consumers want only the most basic of e-bike features, including lights, a cargo rack/basket, and a water bottle holder. Others are focused more heavily on safety features, such as brake type. And still others are concerned with convenience and portability.
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.
Out on the road the Soho is easy to fire up, just press the button hidden under the top tube (a nice discreet touch), you’ll then get a set of five top-tube mounted LED’s light up to give you a charge indication. First impressions were that the engagement of the motor is a little jerky in tight traffic (tested in central London) and you could find yourself pulled toward the cars you’re weaving though at slow speeds - unless you’re feathering the brakes.
What a treat to do business with the folks at Hill Topper. I now have two commuter units one in Idaho and one in Denver my average ride is 25 to 35 miles. I have been riding for about 15 years but being the age of 80 I needed a little help the past few years. I researched electric bikes a few years ago even rode a couple here in Denver but I wanted my own personal look and feel. So about five years ago I found Hill Toppers. What a treat first the units are the best but that is part of the good part the people at Hill Toppers are the very best to work with and enjoy. I had to have a knee replacement last July well thank god for my bike it was the best therapy I could ask for. When in Idaho I get to ride along the Snake river what a treat knowing that I have this unit to help if the wind or rain shows up. When in Denver I cover a lot of area as they have wonderful bike trails all over the area. I ride all of the downtown area and the Cherry Creek dam up and over it takes some effort to get that done but with the help of Hill topper it is a beautiful ride up and overlooking the whole of Colorado. Thank you Andrew,Charles,Sam,Mark.

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.
