It’s always good news to hear a gasoline carmaker is continuing its electric mobility adventure, and what better way to do this than to stray from low-hanging fruits such as SUVs and pickup trucks. GM is no stranger to bold moves and we hope it will continue with the same determination to bring us more Volts, Bolts, and why not electric folding Jolts? (No, Jolts is not my personal entry for the $10,000 prize.)
Our high performance electric bikes offer high power, predictable handling and near silent operation. If your rides take you up steep single track trails or you just want a bike as light weight as possible, a mid drive system will offer the best hill climbing performance, lighter weight, and better weight distribution. A hub motor system will offer the most reliable day in and day out operation, faster speeds, more power, and is a better overall platform for everyday commuting.
There’s a feeling people get when everything just clicks on a ride, and the Roll is a bike that pulls it all together for you. Take it on a bike path and enjoy the smooth ride afforded by a lightweight frame and Ground Control Positioning. Feel the confidence a wider, more stable tire provides. And ride longer with the Body Geometry science that’s gone into the saddles, grips, and pedals. Get out there, get active, and feel it for yourself.
Time to give some love to my dudes and dudettes over at Bulls bikes. The Bulls E-Stream Evo AM 4 27.5+ (phew, out of breath after saying that one) is an incredible electric bike for the price point. I was going to put the step down from this bike on the list, (2018 Bulls E-Stream Evo AM 3 27.5+) but I realized that this bike is only $400 dollars more. The upgrades you get for that 400 bucks are pretty remarkable.
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.
The removable 460 Wh battery is hidden in the downtube, and the custom-built-for-Specialized Brose motor is integrated around the bottom bracket, and develops 250 watts of power. A torque sensor detects when you’re applying pressure to the pedals, and provides assistance when you need it. Aside from the glowing green LEDs indicating charge levels and output settings, there is little indicating this Turbo is anything but a typical mountain bike.
XB-300-SLA X-Treme Electric Mountain Bicycle is a great bike for the novice as it is easy to ride with simple steps. It is an affordable bike with high-quality features that work on a motor of 300 watts and offers a speed up to 20 MP on a single charge. It takes up to 4 hours to fully recharge the battery for the next use. The comfortable padded seat, 18-inch steel frame, 7-speed tourney gear, 24V lead acid battery, power assist system, and steel front forks are a few features that make it popular.
Name a type of riding, and there’s an e-bike for that. If you have zero interest in an electric road bike, you may find yourself head over heels for a high-capacity e-cargo bike that can haul 400 pounds of stuff while still cruising at a cool 15 mph. E-bikes are available in fat, cargo, commuter, recreational, hardtail, full-suspension mountain, and even performance road bike styles. For proof, here are a dozen e-bikes we love for every type of cyclist.
While I was waiting patiently for my 2017 model eBike to be manufactured and delivered, I came across an article in the local paper about a woman with a degenerative muscle disease who wants to take her eBike on forest service trails that are designated for mountain bikes. “What the hell?” I said, completely floored (what I actually said isn’t fit for publication). When I ordered this bike, the thought hadn’t even crossed my mind that it would be illegal to ride on mountain bike trails with my new, albeit electric, mountain bike.
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.
The time or distance an electric bike battery will run between chargings is impossible to judge with much accuracy. There are too many variables: terrain, speed, rider weight, bike load (shopping, kids, luggage), and more. However, we can make a few generalizations about an e-bike’s recharge time and overall working life. These generalizations should be used for comparison purposes only.
For those looking for a fast, versatile, and highly capable full suspension ride should seriously consider taking the Powerfly 7 FS Plus for a spin. Reason being, not only does the ride host an integrated mountain-specific Bosch motor with a top speed of 20 mph, but a full RockShox suspension setup, mid-fat tires for enhanced stability, and high-end mountain bike components work to elevate your mountain biking experience for the better. From rough to nearly impenetrable terrain the Trek Powerfly could very well be the solution to your desired exploration.
Range is a key consideration with e-bikes, and is affected by factors such as motor efficiency, battery capacity, efficiency of the driving electronics, aerodynamics, hills and weight of the bike and rider. Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes, have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging. This is useful for extending the range and the life of brake pads and wheel rims. There are also experiments using fuel cells. e.g. the PHB. Some experiments have also been undertaken with super capacitors to supplement or replace batteries for cars and some SUVS. E-bikes developed in Switzerland in the late 1980s for the Tour de Sol solar vehicle race came with solar charging stations but these were later fixed on roofs and connected so as to feed into the electric mains. The bicycles were then charged from the mains, as is common today. While ebike batteries were produced mainly by bigger companies in past, many small to medium companies have started using innovative new methods for creating more durable batteries. State of the art, custom built automated precision CNC spot welding machines created 18650 battery packs are commonly used among Do-it-yourself ebike makers.
While in many areas of the country you are allowed to drive mountain electric bikes in urban settings, some local jurisdictions may limit their use as some models reach 28mph exceeding the on road accepted limit of 20mph. So before you purchase one of these bikes, make sure to check the local laws in your given area. These bikes are good for many different age groups including teens and adults.
If you haven’t ridden or even seen a modern eMTB, here is what I have discovered. They are sturdy rigs that come standard with quality mountain bike components including beefy forks and rear suspension systems, strong disk brakes, and a reliable drivetrain. They are heavy but not that far out of the old downhill bike weight class. The distinguishing “e” features are the electric motor at the bottom bracket (some have hub motors), the battery pack, and the handlebar-mounted computer that controls the system. They have adjustable assist modes: off, low (barely helps), medium, and the battery-draining high mode. When everything is put together, they are something to behold.

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.
