It’s probable that GM was hoping for more press for its announcement of the same day as Musk’s interview going live, that it had actually built and was going to sell a pair of electric bikes. It launched a $10,000 naming contest. The bikes were built in-house by GM, including engineers who had worked on the Bolt. The Director of General Motors Urban Mobility Solutions, Hannah Parish said:
On a trip to Palo Alto last year, we had the chance to ride Specialized’s pedal-assisted Turbo Vado and the model is still our favorite ebike on the market. Utilizing a 350-watt motor and 604-watt-hour lithium-ion battery, the Turbo Vado is capable of traveling a whopping 80 miles on a single charge, which should be more than enough for any daily commute with plenty of miles left over.
Countless others have popped up since all over the world, proving that the design has been popular with consumers. However, most people don’t know where the craze started. In fact, it can all be traced back right here to Coast Cycle’s original Buzzraw, which actually started life as Coast Cycles’ Ruckus bike. The Singapore-based company quickly changed the name to Buzzraw, probably fearing Honda’s lawyers.

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.
This past July 1st we moved our location to Croydon, PA and doubled our space. Additionally we're looking to hire at least 2 additional employees! This is all to support our expanding conversion kit business and to support some new business we have planned starting in September (more to come on that soon). We would like to thank every single one of our customers, partners, associates and fans for your...
It’s important to note that because this is an electric bike, not all trails are legally accessible. You’ll need to check with the federal, state, or local land management agency in charge of the trails you want to ride to see if it’s possible. You may also face some resistance from holier-than-though cyclist types. Those guys are best avoided anyway, and the glowing LEDs on the down tube should at least help you identify them quicker.
Catrike Expedition converted with a 26" Performance E-BikeKit This Catrike Expedition was a custom conversion done at Electric Bike Technologies in Croydon, PA. If you have a Catrike Expedition and wish to convert it on your own, the following may help. If you would like to purchase the kit and add-ons used in this conversion, you can order them from our online shop or call us at 866.882.3245 M-F 9am-5pm EST....
REBEL electric bikes powered by the Yamaha central motor create Dynamic and Responsive Power. It also enables the use of a conventional groupset and offers no resistance in «no assistance» mode. The eMTB bikes range have an “External DT System” battery, located in the front triangle and integrated with the design of the frame. The relative position of the less lightweight parts of the system (motor and battery) enables a low center of gravity, guaranteeing a reactive and stable ebike. See the REBEL electric bike models...
Those are our choices for the top eMTBs this year. There are loads of great options as battery life continues to improve and motors provide more assistance than ever before. Electric bikes are primed to move heavily this year. It’s the only bike market that continues to grow every year. The more units that sell, the better the bikes become. That’s great for consumers and the bike community in general!
The Netherlands has a fleet of 18 million bicycles. E-bikes have reached a market share of 10% by 2009, as e-bikes sales quadrupled from 40,000 units to 153,000 between 2006 and 2009, and the electric-powered models represented 25% of the total bicycle sales revenue in that year. By early 2010 one in every eight bicycles sold in the country is electric-powered despite the fact that on average an e-bike is three times more expensive than a regular bicycle.
In a parallel hybrid motorized bicycle, such as the aforementioned 1897 invention by Hosea W. Libbey, human and motor inputs are mechanically coupled either in the bottom bracket, the rear wheel, or the front wheel, whereas in a (mechanical) series hybrid cycle, the human and motor inputs are coupled through differential gearing. In an (electronic) series hybrid cycle, human power is converted into electricity and is fed directly into the motor and mostly additional electricity is supplied from a battery.
