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...

Another great thing about this particular electric bike is that it comes with a Nuvinci shifter and belt drive system. This replaces a traditional derailleur, chain, and cassette. This means there is no need to tune your drivetrain or fix a broken chain. Nuvinci systems are virtually maintenance free, which is great for beginning bike tourists who don’t want to spend half a day figuring out what went wrong with their drivetrain.
This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection - our Direct-Drive motors are now all High-Torque 6x9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the...
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...
The final major consideration is what type of riding you will be doing. Are you going on an off-road adventure through the mountains? You’ll want a very different electric bike than you would need if you’re riding on paved roads the whole time. Most bike tours are going to be on paved roads, but you should always research the area in detail during your planning process.
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.
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.
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.

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.
Fast and fun on the trail, the SDURO HardNine handles rough terrain with ease, while its large tires roll over most obstacles without missing a beat. The pedal assist makes for quick, energy-saving climbing and the bike descends surprisingly well, too. Its front suspension provides a nice level of cushion on bumpy trails and while we missed having a full-suspension on this model, that would have added additional weight and costs.
BattleBots legend Christian Carlberg and his company C2 Robotics are using Electric Bike Technologies direct drive hub motors to power 'OverDrive', their latest BattleBot on ABC!   Team C2 Robotics is set to battle again tonight at 9pm EST on ABC!

Because they’re electrically powered, e-bikes sit in a bit of a gray area between bicycles and motorcycles. While some states have enacted specific legislation to state where electric bikes can and can’t be ridden, in other states outdated laws mean they’re regulated as a moped or motor vehicle which can cause confusion over registration requirements, access to cycling infrastructure and how old you have to be before you can ride one.
If the bike is in fact similar to the EB-5, then it is probably a great around-the-city or campus electric bike, but perhaps not the best long distance commuter for rough roads. Though considering the bike won’t ship for at least another 4 months and the US shipping cost will bring the total price of the Spark Drive Mini to $499, impatient riders might be better off with the equally priced and Amazon-shipped EB-5 anyways.
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]

Tackle your daily commute with ease or go for a weekend cruise in style with the Gazelle CityZen T10 e-bike. And don’t worry about those thigh-burning hills; the Bosch motor offers four assist levels—Eco, Tour, Range Sport, Turbo—making hills a breeze and the Lithium-Ion battery provides a range of up to 85 miles in Eco mode. The bike is one of the first to use Bosch's new integrated battery, which is concealed in the downtube. The matte black paint and classic, step-through design give a classic look while fenders, pannier racks, and integrated lights add practical functionality. The bike is easy to maneuver in city streets, but still has assist up to 28mph so you can cover a lot of miles and power up steep hills. There's a suspension fork too. It's not at the level of something you'd find on a mountain bike (or even some better e-bikes) but it takes the edge of some potholes and curbs.
