Glenn has over 15 years of experience building bicycle wheels and has worked for and with the local cycling community in the Philadelphia area for the past 20 years. Glenn is in charge of all wheel building activities at E-BikeKit and oversees quality control on wheels built in the Newportville, PA location. Since joining E-BikeKit in early 2010 Glenn has had a huge impact on the success of the company...
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.
Electric bikes and E-bike kits (bikes with electric conversion kits) are part of a wide range of Light Electric Vehicles (LEVs) that provide convenient local transportation. Generally designed for one person and small cargo capacity, electric bike range, speed, and cost are moderate. For most of us, the majority of our trips are less than 20 miles - within the range of most e-bikes considering the latest advances in affordable lithium batteries. Clean, quiet, and efficient LEVs offer the advantages of an extra car without the burdens.
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.
You should be extra aware about your local regulations as in many countries an L1e-A certified bike needs to be registered and insured (be sure to consult your local laws and rules) and with registration comes the security that the bike can be tracked if it is stolen or misplaced. This approval that we have received is European Union wide and even those countries that are not part of the EU but rather EEA do adopt similar regulations in order to keep the market common but you will need to consult with your authorities. We will detail more about the registration process in an upcoming blog post but if you have any questions you can email us and we will respond in kind.
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. Their bikes are over-engineered to over-perform and yet stubbornly maintain value over time.
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...
The eZeeBike has been a successful and sought-after line of e-bikes in Europe that are now available in the United States. Range of 30 miles and top assisted speed of 20 mph is possible with the three standard (non-folding) models. With well-crafted aluminum alloy frames and lithium batteries, these bikes are lighter than other electric bikes. Equipped with 250- and 350-watt silent (gearless) hub motors, eZee bikes come with many accessories as standard equipment. Different models may include: fenders, front shocks, suspension seat tube, Velo cycle computer , integrated front and rear lights, rear luggage rack with spring-loaded bar and integrated bungy chords, chain guard, and foldability.
On the other end of the pricing spectrum (although not as high-end as possible) falls the Riese & Muller lines. The Nevo line, which features a Bosch motor, hydraulic disc brakes and speeds up to 28 mph also has a roughly $5,000 sticker (a variety of models allows for a cheaper price). Using a carbon belt and Nuvinci grip shifter, maintenance worries lessen. The German-made premium models are hand made to specifications and comfort reigns supreme.
While the first electric bicycle was invented way back in the 1890s, historically e-bikes have struggled to gain momentum, only breaking into the market in mainland Europe at the turn of the 21st century. E-bikes now account for 38.5pc of all bicycles sales in Germany (Holland and France and also big players); belatedly, the trend is starting to register in the UK. Battery assisted bikes now make up around a third of bike sales at Evans Cycles West End.
DRIVE MOTOR The EcoBike is powered by an innovative hub-mounted, brushless permanent magnet motor with a triple planetary gear drive system and proprietary heat resistant materials. The propulsion system delivers the highest torque and is the quietest in its class. The drive motor is nominally rated for continuous output at 360 watts (Elegance & Adventure) and 290 watts (Vatavio).
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.

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.

I picked this bike because it’s definitely one of the lowest cost 28mph bikes out there that is still high quality. Magura MT4 hydraulic disc brakes keep you good and safe. The geometry provides a comfortable ride. Personally, I don’t always think a suspension fork is totally necessary since they are less efficient. If you’ve got a pretty smooth road to ride this is a great option.
