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.
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.
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).

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.
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.
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]
ELECTRONIC CONTROL  The Zero-Smart-Start speed controller delivers ease of use and smooth drive control and offers a multi-function variable speed output.  It is state of the art, producing consistent efficient power.  The automatic Pedal Assist mode produces a power burst that dramatically assists the pedaling effort.  The Zero-Smart-Start electronic throttle control allows the rider to relax and not pedal at all.

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.

The UpCycle Eco-Charger is a Powerful Bicycle Generator that Utilizes an E-BikeKit™ Hub Motor and Empowers You to Generate Your Own Electricity!   The UpCycle Eco-Charger was created by Adam Boesel, the founder of The Green Microgym Say goodbye to worrying about environmental disasters and hello to making the world a better place. The UpCycle Eco-Charger is the most efficient, reliable, and powerful bicycle generator ever. Over the past two...
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...
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]
Unlike most e-bikes, the Brompton's battery is integrated into a bag that sits on the front of the bike. While that detracts slightly from the classic, streamlined design, it's handy as it can be unclipped for charging or riding as a regular bike – it's probably one of the easiest to ride without battery assistance thanks to its weight. The battery also powers two lights for safe commuting. 

Alec wants your wheels to be strong and true when they leave our doors, and a well-built wheel will stay that way for years.  Alec would rather be outdoors, but he comes in to E-BikeKit each day to make sure that you’ve got what you need to make your own outdoor adventures happen. A day when Alec can keep you rolling down the road and enjoying your bike is a...

It’s only available in one frame size but the low top tube, adjustable seat and more upright riding position make it comfortable for people of different heights. The low-ride cargo rack and smaller (20-inch) rear wheel lower the center of gravity making the bike easier to maneuver. This is a workhorse of a bike that could easily replace a second car for most day-to-day necessities.

Because the power is applied through the chain and sprocket, power is typically limited to around 250–500 watts to protect against fast wear on the drivetrain. An electric mid-drive combined with an internal gear hub at the back hub may require care due to the lack of a clutch mechanism to soften the shock to the gears at the moment of re-engagement. A continuously variable transmission or a fully automatic internal gear hub may reduce the shocks due to the viscosity of oils used for liquid coupling instead of the mechanical couplings of the conventional internal gear hubs.
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.
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.
