China's experience, as the leading e-bike world market, has raised concerns about road traffic safety and several cities have considered banning them from bicycle lanes. As the number of e-bikes increased and more powerful motors are used, capable of reaching up to 30 miles per hour (48 km/h), the number of traffic accidents have risen significantly in China. E-bike riders are more likely than a car driver to be killed or injured in a collision, and because e-bikers use conventional bicycle lanes they mix with slower-moving bicycles and pedestrians, increasing the risk of traffic collisions.
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
Using an electric bike for long-distance touring has its pros and cons. The motor will help carry the extra weight of your kit, particularly on the hills, but you have the added hassle of having to charge the battery every night. You’ll want a powerful motor and a good battery, though if you’re fully loaded, don’t expect to achieve the maximum advertised range.
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.
Having never ridden one before, I took a few electric bikes out to review in Central London and was an instant convert. For a commuter, they're ideal. While you still feel you've done exercise, the assistance means you won't arrive at work in a hot and sweaty state. The power boost whenever you start from a standing position is ideal for a speedy getaway at a traffic light with buses and lorries right behind you. And you'll get a nice ego boost every time you effortlessly ride past a struggling regular cyclist.
This bike is named the GSD because with it you can Get Stuff Done. Twenty-inch wheels keep the center of gravity low so heavy payloads—it's rated up to 400lbs—are easy to balance and a short (for a cargo bike) 70-inch wheelbase, similar to a standard single bike, make the GSD easy to maneuver. Designed with the urban commuter in mind, the bike can easily break down to 60 percent of its original size to fit into the back of a car and the rear rack doubles as a stand that allows it to stand upright to minimize space inside tight apartments. Put two child seats on the back and take the family along, or drop the seat and let you kid take the bike out himself—anyone from 4'10" to 6'5" can ride this bike. Last but not least, the GSD gives you the option of adding a second battery to extend your range up to about 150 miles on a single charge.
China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008, and reaching an estimated fleet of 120 million e-bikes in early 2010. This boom was triggered by Chinese local governments' efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities. Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car. Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007. By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.
“Second, even if you do make bikes in the US, they will be multiple times more expensive than their overseas counterparts and 99.9% of consumers won’t pay that price. When my shop tried selling a US-made bike next to a Chinese bike, with signage that explained why the US-made bike was more expensive, we couldn’t even sell one. Customers would stand there and talk about how they want American-made goods, then they would buy the Chinese bike.”
Built by a company that’s made cycling equipment for more than four decades, the Vado feels more like a traditional bicycle than almost any other ebike. Its frame and components have been tuned to provide a familiar experience, making it easy for new and long-time cyclists to jump on and start pedaling. Specialized’s heritage shines through nicely, helping separate itself from the competition in an increasingly crowded ebike market.
There are two basic categories of electric bike, and their uses don't offer equal crossover value. The first category is essentially a normal bicycle that has been outfitted with an electric motor. These bikes are the same size as a standard bicycle, and handle almost identically, save for the obvious benefit of added motive power thanks to a motor and battery.
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...
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.
The Soho is one of Coboc’s four single-speed pedal-assist bikes. The bikes are differentiated with finishing kit - handlebar style, bar-tape, saddle and paint finish. With a retro / bespoke styling with Bullhorn bars, Brooks fabric-tape and Cambium saddle and brushed aluminium frame, the Coboc is an e-bike for riders who don’t want to look like they’re riding an e-bike. The ONE Soho is for a rider that doesn’t want gears either.
Electric bikes are here in a big way. Liberated from some of the normal constraints of standard bike design like weight and gearing, e-bike design has exploded; if you can imagine it, someone has built it. From cargo bikes to city bikes, messenger bikes to mountain bikes, road bikes, and even beach cruisers, there is something for everyone. The beauty of e-bikes is they make the joy of cycling accessible to so many people in so many ways.
