Upper Dublin Township in Pennsylvania is initiating a pilot project to gauge the advantages of using electric bicycles. The e-bike, as they are more commonly known, will be used for police work and for the Township’s Sitewatch program, which patrols and monitors parkland and playing fields. The people behind the program believe the electric bike could prove to be a useful tool, giving police officers and parks personnel a clean,...
On the 8.0 specifically, Haibike sets you up with the brand new Yamaha PW-X motor. This motor comes standard with a 500 watt hour battery, Bluetooth connectivity, and 80 nm of torque out the gate. The PW-X also boasts the benefit of a dual chainring up front. This means you’ll save some battery if you’re willing to work a little harder and use those gears! Speaking of gears, you’ll get a Shimano Deore XT drivetrain. Pair that with Fox 34 Float Performance front suspension and a Fox Float DPS rear shock (150mm travel) and you’ve got a fully-capable, all-around ride.
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.
I know that this topic is new and still contentious, but the community needs to be talking about it because it isn’t going away. The weather up here in Seattle is rainy and cold (no surprise there), so I haven’t ridden my new eBike except around the block to make sure it worked. I can’t wait to hit the trails (legally or illegally). Expect a follow up comparing the eMTB to my other mountain bikes both in how it performs and the feeling I get from riding it. I never thought I would be riding an eMTB, so trust me, I won’t hold back.
And let’s not forget the economic advantages of owning an e-bike. The annual cost of running a new family car is, on average, about $9,000 per year. Running an electric bike costs around $400 per year. And while filling a gas tank costs around $30, recharging an electric bike battery costs only about 50 cents. A tank of gas may get you further, but not 60 times further!
As a household name, Specialized is to be trusted in this world without a doubt. That’s because, in addition to their inventory of pedal-powered machinery, they’ve gone ahead and introduced us to their S-Works Turbo. Here, in conjunction with their custom Trail-tuned motor for off-road use, the Levo FSR frame is constructed entirely of FACT 11m carbon fiber allowing for both a lightweight and stiff ride through the local wilderness. Additional features include instant engagement, heat management, and a silent output for good measure. Not bad Specialized. Not bad at all.
Assembly was pretty simple and straightforward, there are some videos online explaining it. Definitely important to know how to switch it on, though -- pressing the "M" button for two seconds with the key in the "on" position. Despite being a heavy bike, it's very quick and nimble. I ride about 15 miles per day and was able to get two trips out of it before charging, riding fast. My only complaints are the squeaky brakes, and the front fender. Said fender is a bit too close to the tire on the front wheel and doesn't mount very securely, so it kept making very loud noises as it would catch the tire whenever I went over a bump or had to brake hard. I just took it off for the time being.
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.
Riding a pedal-assisted road bike may seem counterintuitive but during longer training sessions, the minimal addition of power helps prevent overall muscle fatigue and injury. Similarly, those looking to enjoy longer scenic routes will appreciate the general boost an electric drive provides. With a top speed of 28 mph, the Road E+1 uses three power modes to give you ultimate control over your ride and assistance level. A four-point sensory system monitors the pedaling force allowing the motor to amplify your movements seamlessly.
On mine I got the Topeak front and SKS rear mud guards, an Axiom rear rack, front and rear lights. They didn’t have a headlamp with the lumens I wanted, so Tommy the owner went ahead and ordered one for me! He was always available for any question I may have had through his mobile phone, and updated me with pictures showing me different possible setups to see if I would like it.

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...
The Haibike AllMtn line makes an appearance again with this incredible price-point option. The AllMtn 6.0 is a nice option with entry level components but the same aggressive build as the rest of the AllMtn line. And when I say entry level components, I definitely don’t mean that as a negative. You still get 150mm of travel with a Suntour Aion 35 RC suspension fork, a RockShox Deluxe RT rear shock, Magura MT32 hydraulic disc brakes, and Shimano Deore M6000 drivetrain with 20-speeds.
Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike. The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.
