There are two main types of motor to suit different riding styles. The durable, "heavy duty" Direct-Drive motor, and the lightweight, efficient and fast "performance" geared motor. Electric Bike Motors, hub motors in particular, and electric bike batteries are what make electric bicycles go. Using a hand throttle you control the flow of electric current from the battery to the brushless motor. With an intelligent 20 Amp controller regulating the...
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...
Proud to assemble the first Stromer ST5 in the US for a very special customer! @vancityreynolds #Repost @stromerbike with @get_repost ・・・ Ryan Reynolds is since 5 years a happy user of Stromer.

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.
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
Whether the terrain is flat or hilly impacts the distance you can travel, as does the weight of the bike, your own weight, the gearing available on the bike, and how much juice you give it. We suggest that a distance of 10 to 20 miles is a realistic expectation. Of course, if you're prepared to do at least some pedaling, you can extend that dramatically.
"Electric bikes are great for giving you an extra boost and a bit more zip for when you're a bit low on energy," says two-time Olympic gold winner Victorian Pendleton. "E-bikes are also a fantastic route into cycling for beginners, or for those returning to cycling, as they provide a helping hand when it comes to conquering physical fitness challenges."
The wiring could be better, but I think I’m going to make some adjustments to that myself. It’s also worth noting that the motor is in the rear hub just like a basic commuter ebike. This will affect the way it feels, as bottom bracket motors give a more seamless “pedal assist” experience. Of course, this bike seems like it’s made as practical transportation. To me, anything that gets cars off the road is a good thing so lets take it for a ride.
Riding position: You also may wish to check out an e-bike’s riding position before investing in it. For short trips, the riding position might not make much difference, but for long journeys, the upright "Dutch" style with pulled-back handlebars is very comfortable – particularly for tall riders. The same goes for mountain bike styles, though these bikes are not often designed to actually go off-road.
Because e-bikes are capable of greater speeds for longer periods of time than standard bikes, you want extra control. Wider tires provide traction and some bump absorption with little penalty. You also want strong brakes to slow you (and all that extra weight) easily. It's worth looking at the quality of the brakes and investing in bikes with better ones if you can.
