We rode the Vado through the gauntlet, including some of the steepest hills in Palo Alto, and it easily handled everything we threw at it, maintaining a steady 20 miles per hour even on the most daunting of ascents. The bike also handles well on downhills and is both nimble and quick on city streets and paved trails. It’s even comfortable to ride for extended distances, which is vitally important for any bike built for urban settings.

Designed for the same maneuverability as a non-electric bike, this roughly $3,000 model designed for the city can handle hills and distance. Using a Bosch motor for 100-mile cycling on flat or hilly terrain and a lightweight aluminum frame, the Dutch-made Gazelle model aims for a “sporty posture” and “precise cycling performance” in a robust offering.

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.

Added help on the hills: An extra boost on the hills or when cycling into a headwind is probably the first thing most people think about when they’re considering an electric bike. If you live in a valley where the only way out is up, then having a bit of motor assistance may mean the difference between a happy cycling experience and not cycling at all.
I wanted to include an electric bike that would be ideal for off-road and trail bike touring, and I think the Bulls E-Stream Evo 3 27.5 Plus is it. This hardtail mountain bike would be perfect for bike tourists going out on the trails for a few days. You could conceivably go for a few days without needing to recharge the Brose 650 watt hour battery, so even if your camping in the wilderness with nowhere to recharge for 60-100 miles you would likely be fine on battery life.
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.
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.
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.
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.
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...
The environmental effects involved in recharging the batteries can of course be reduced. The small size of the battery pack on an e-bike, relative to the larger pack used in an electric car, makes them very good candidates for charging via solar power or other renewable energy resources. Sanyo capitalized on this benefit when it set up "solar parking lots", in which e-bike riders can charge their vehicles while parked under photovoltaic panels.[66]

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]
E-bike usage worldwide has experienced rapid growth since 1998. In 2016 there were 210 million electric bikes worldwide used daily.[33] It is estimated that there were roughly 120 million e-bikes in China in early 2010, and sales are expanding rapidly in India, the United States of America, Germany, the Netherlands,[2] and Switzerland.[34] A total of 700,000 e-bikes were sold in Europe in 2010, up from 200,000 in 2007 and 500,000 units in 2009.[35]
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]

This dexterous electric dirt bike is recommended for anyone over the age of 14. It’s fitted with double suspension and big tyres to help you tackle tough terrain. You also get a good selection of gears, that gives you optimal control. The Razor can go as fast as 15 mph on average, and comes with an excellent braking system. The aesthetics are on point, and the racer look is sure to impress. Don’t forget your helmet!
The bike recently took first place at the Interbike Hill Climb Challenge, a third of a mile sprint up a six per cent gradient hill. Fortune powered in front of professional riders to secure a decisive win in the first of an annual competition especially created for electric assist bikes. The race was sponsored by the Light Electric Vehicle Association (LEVA).
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.

One of the biggest misconceptions about e-bikes is that you're not actually doing any work when you ride one. Not true. Thanks to that battery-powered motor, E-bikes are heavy! So if you turn the assist mode to low or off, you're still putting in plenty of effort. Many commuters have found that traveling home from work with assist off (when they're not in as big of a rush and don't mind getting sweaty) is a great way to fit exercise into a busy schedule.
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...
This bike is designed for hauling. The Yuba Spicy Curry has a combined capacity of 500lbs (200lbs on the front including rider, and 300lbs of passengers or cargo on the back). To help move this weight, you’d expect a decent motor, and the Bosch Performance Line CX delivers. Normally only found on mountain bikes, the 75Nm of torque makes light work of hills, even with the heavy load.
The Panasonic Akku cells used in this pack are among the best lithium polymer cells Panasonic makes, which is one of the finest names in the industry for lithium battery technology. This means the pack will give you years of long life without worries about a battery fire or breaking down. The battery, along with the rest of the components of this electric bike, come with a 2-year warranty. The bike comes with a relatively fast 200-watt charger that will refill this pack in only 2.5 hours. And the battery locks into the bike with a key lock, good for preventing theft. The battery pack includes a built in battery meter that shows battery level whether it’s on or off the bike.

Thanks to clever engineering, the Electric Brompton folds up identically to the non-powered variety. It is heavier than a standard Brompton of course, but quite light by e-bike standards. It has small , suitcase-style additional wheels that come into play once folded up, and the way the weight is balanced means it is quite straightforward to trundle along in that state.  
On the road, it takes only a few turns of the pedals to activate the Vado’s motor and get it up to speed. In Turbo mode — the bike’s highest level of pedal-assist — the Vado reaches speeds of up to 28 miles per hour, after which the electric drive system automatically shuts off to conserve power (and abide by local law). A built-in LED readout on the handlebars allows riders to monitor battery life, check current speed, and track calories burned while also being able to glance at distance traveled. The Turbo Vado Mission Control app (iOS/Android) also connects to the bike via Bluetooth and allows riders to further tune their ride and adjust the bike’s settings.
Look at Bulls giving you options! Very similar bike, but with the Bosch Performance Speed motor. Why did I include if it’s so similar? Because I think Bulls has build super interesting commuters. They set you up with a adjustable stem so you can literally be as upright as you want, if you’re a posture freak. Underrated part of this bike: water bottle boss placement. Call me crazy, but it’s little touches like these that tip the scales on commuting bikes for me. It isn’t always easy to find places to put cages on e-bikes.

Irvine, Calif. – As eBikes transform into a "lifestyle product," smart aesthetics and attractive design play an increasingly important role. That’s why Bosch eBike Systems is setting the pace: for Model Year 2018, presenting the PowerTube 500, a battery which can be integrated into the frame of the bicycle. The PowerTube 500 combines modern design with first class Bosch technology for eBikers who prefer a clean and timeless look.
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.
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, at the same time, tough. 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.
TerraTrikes make great electric recumbent trikes. Here are a few how to tips for converting the Rover and Rambler models, specifically with internally geared hubs. The TerraTrike Rover and the rambler models both are offered with internally geared hubs. It is possible to convert the trike to external gearing, but you will probably want the help of a bike shop that is familiar with recumbents. For a good bike shop,...

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 the geared motor, a small and lightweight motor spins very fast inside. The electric bike motor then uses a planetary reduction gear inside the motor to reduce the rpm to the correct speed for a bike wheel. Electric Bike Motor An electric bike motor on an electric bike can be any kind of electric motor. There have been some very creative home brew e bikes that used any motor...

There are two basic categories of electric bike, and their uses don't offer equal crossover value. The first category is essentially a normal bicycle that has been outfitted with an electric motor. These bikes are the same size as a standard bicycle, and handle almost identically, save for the obvious benefit of added motive power thanks to a motor and battery.
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.
Some power-on-demand only e-bikes can hardly be confused with, let alone categorised as, bicycles. For example, the Noped is a term used by the Ministry of Transportation of Ontario for e-bikes which do not have pedals or in which the pedals have been removed from their motorised bicycle. These are better categorised as electric mopeds or electric motorcycles.
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.
This bike is named the GSD because with it you can Get Stuff Done. Twenty-inch wheels keep the center of gravity low so heavy payloads—it's rated up to 400lbs—are easy to balance and a short (for a cargo bike) 70-inch wheelbase, similar to a standard single bike, make the GSD easy to maneuver. Designed with the urban commuter in mind, the bike can easily break down to 60 percent of its original size to fit into the back of a car and the rear rack doubles as a stand that allows it to stand upright to minimize space inside tight apartments. Put two child seats on the back and take the family along, or drop the seat and let you kid take the bike out himself—anyone from 4'10" to 6'5" can ride this bike. Last but not least, the GSD gives you the option of adding a second battery to extend your range up to about 150 miles on a single charge.
