The bicycle is also used for recreational purposes, such as bicycle touring, mountain biking, physical fitness, and play. Bicycle competition includes racing, BMX racing, track racing, criterium, roller racing, sportives and time trials. Major multi-stage professional events are the Giro d'Italia, the Tour de France, the Vuelta a España, the Tour de Pologne, and the Volta a Portugal.

Like most electric bikes, the Rad Wagon is also fairly heavy, weighing 72 pounds. The last drawback is that it comes in only one frame size (which I imagine helps to keep costs lower) that fits rider heights between 5 foot 2 inches and 6 foot 2 inches. My 6 foot 4 husband, however, can ride the bike just fine, so there’s some wiggle room to this range.

The two most common types of hub motors used in electric bicycles are brushed and brushless. Many configurations are available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design. The motor is built into the wheel hub itself, and the stator fixed solidly to the axle, and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.
As is the case with any e-bike assembled from Chinese parts, Wing has its share of clones that can be found for sale on sites like IndieGoGo and Kickstarter. For example, the Danish company Strom Bikes has a model for city biking that also looks incredibly similar to Wing’s Freedom — and is apparently several hundred dollars cheaper too. This is also commonly found with electric scooters, with startups buying Chinese-made models and rebadging them for sale in the US.
E-bikes are typically offered in 24V, 36V and 48V configurations. Higher voltage generally means higher top speed – but that may not always be the case. Since the efficiency of a motor and drive system can have an effect on power and speed, a 24V setup could have the same top speed as a 36V setup. Generally you can expect 15-18 mph on a 24v setup, 16-20 mph on a 36V setup and 24-28 mph on a 48V setup. Although it far exceeds Federal laws, some conversion kits can even be run at 72V for speeds of 35+ mph! However, this puts significant stress on bicycle components. Consider that even the fastest athletes only travel 17-18 mph on a conventional bicycle, so 20 mph feels very fast to most riders. Anything over this speed can be unsafe and exceeds law regulations.

Yes, there are less expensive ebikes on the market but most come with a few serious caveats. The Espin Sport delivers on the full promise of an electric bike, but in a more affordable fashion. This bike isn’t going to tow you around for a 60-mile round-trip endeavor but those seeking their first ebike will get plenty of return on their investment with this model.
As the managing editor of Ars Technica, one of my duties is to monitor the daily torrent of news tips and PR emails. The overwhelming majority of them is deleted after a glance, and the news tips and story ideas are passed along to the appropriate writer. Sometimes a product announcement will catch my eye, and I will follow up. Once in a blue moon, I'll say, "please send me one so that I may review it." And that's how I ended up riding an electric bike around the Chicago suburbs for two weeks.

There are no ADRs applicable to AA or AB category vehicles. There are ADRs for lighting, braking, noise, controls and dimensions for LA category vehicles, mostly referencing the equivalent UN ECE Regulations. An approval is required to supply to the market any road vehicle to which ADRs apply and an import approval is required to import any road vehicle into Australia.[5]
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.
^ Consumer Product Safety Act, Pub. L. 107–319, December 4, 2002; codified at 15 U.S.C. 2085(b): The CPSC regulations do not differentiate between commercially manufactured low speed electric bicycles and those converted from ordinary bicycles by their owners using an aftermarket electric motor and battery kit, nor do they regulate the construction of electric-power bicycles using owner-built or sourced components.
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.
Cargo bikes and city bikes are common in the e-bike space, but until recently we haven’t seen that many performance road bikes. The Giant Road E+1 is a pedal-assist performance road bike that’s made for more than just commuting; the powerful motor can crank you up to 28 mph very quickly on the highest setting so you can rip the flats, join your local group ride, or blast through the mountains with far less effort than a traditional road bike. It won’t feel like a 16-pound race bike when you lean it into high-speed turns, but the endurance-oriented geometry allows for an aggressive position on the bike and keeps it nimble and agile at high speed.
The Super Commuter is very aptly named. The 350w Bosch motor will help you sustain speeds of up to 28mph, and the burly, 2.4-inch wide, Schwalbe Super Moto-X 650b tires will keep you secure on even the roughest city streets, and Shimano Deore hydraulic brakes provide ample stopping power. Fenders provide welcome protection from road spray so you arrive at your destination fresh, integrated lights are critical for post-sunset riding, and a side-view mirror hanging on the left side of the handlebar gives a great view of traffic around you. After all, you can ride at the speed of urban traffic on the Super Commuter.
Operators are subject to driving rules and equipment requirements (if applicable) when operated on the public streets or highways (which includes the main traveled portion of the road, shoulder and sidewalk). This means that an operator could be cited for speeding, failure to signal, unsafe change of course, driving on the sidewalk, DWI (this would apply to anywhere in the state and not just the streets/highways), and all other driving rules contained within state law that would apply. They may also not ride more than two abreast and may not impede the normal and reasonable movement of traffic. On a laned roadway, they must operate within a single lane.[citation needed]

I called Geico earlier today. They could insure me with Renters Insurance, but … I would need to have a Renter's Policy first, before the secondary insurance company they deal would insure my two bikes (Surly Long Haul Trucker and Yuba Sweet Curry custom eBike). BUT … unfortunately …. The company that would insure my bicycles will NOT insure me because we have a Pitbull !!! Can you believe that … !!!
Electric bicycles have two main methods of operation: pedal-assist and/or throttle-control. As the name implies, pedal-assist “assists” your pedaling and requires some input. With this method, a torque sensor picks up movement or stress to determine the power requirements of the rider. Everything is automated so there’s nothing to think about, just jump on and start riding. Some bikes have multiple settings, while others have just one setting with the addition of a throttle control. Depending on the setting, pedal-assistance can help a little – or a lot. At lower settings, pedal-assist is barely noticeable but helps extend your range. At higher settings, the power is quite obvious and feels like a strong wind at your back with the motor doing most of the work while you pedal along.
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]
In the 1890s, electric bicycles were documented within various U.S. patents. For example, on 31 December 1895, Ogden Bolton Jr. was granted U.S. Patent 552,271 for a battery-powered bicycle with "6-pole brush-and-commutator direct current (DC) hub motor mounted in the rear wheel". There were no gears and the motor could draw up to 100 amperes (A) from a 10-volt battery.[5]
Staring up the bike path of the Manhattan Bridge on a recent frigid February morning, I feel the familiar dread when confronted with a steep, uphill climb. There are few things more discouraging to a city biker — especially a fair-weather one like me — than an arduous, sweaty ascent in work clothes. But before my thighs can cramp up, I remember that I’m riding a new electric bicycle from a company called Wing.
My one complaint is the bike’s weight. This sucker is heavy! The aluminum frame looks light, but the the hub motor (4 pounds) and battery (5 pounds) add up. The bike’s total weight is 39 pounds, which is about average for e-bikes but not something you’d want to lug around all day. “This is not a solution for everybody,” Miller admits. “If you live in a fifth floor walkup this is probably not going to work.”
UPDATE (2019-03-15): I've now got more than 110 miles on the bike and still loving it. The longest ride I did was 28.5 miles and the display was still showing about two bars left on the battery. But the battery gauge is not accurate. Even when it went down to two bars it would also jump back up to 4 bars and stay that way for awhile. So it's really hard to tell how much power you have left. On one ride, after 14 miles the pedal assist stopped working all of a sudden. I stopped and re-seated the cadence sensor and it started working again. Even when PAS didn't work the throttle was still working. It hasn't happened since. There was also a lot of rattling noises which I found was the battery rattling around in the mounting bracket.

We've also released our first native 72V battery pack in a conventional downtube battery casing, assembled using the high power Samsung 27100 40T cells so that even with the small 8Ah capacity it is able to deliver 40-50A continuous currents. This is an ideal battery for fast and sporty offroad ebike builds, allowing powerful performance without the weight or complexity of most 72V setups (either two 36V packs in series or a large triangle frame battery).

In China, e-bikes currently come under the same classification as bicycles and hence don't require a driver's license to operate. Previously it was required that users registered their bike in order to be recovered if stolen, although this has recently been abolished. Due to a recent rise in electric-bicycle-related accidents, caused mostly by inexperienced riders who ride on the wrong side of the road, run red lights, don't use headlights at night etc., the Chinese government plans to change the legal status of illegal bicycles so that vehicles with an unladen weight of 20 kg (44 lb) or more and a top speed of 30 km/h (19 mph) or more will require a motorcycle license to operate, while vehicles lighter than 20 kg (44 lb) and slower than 30 km/h can be ridden unlicensed. In the southern Chinese cities of Guangzhou, Dongguan and Shenzhen, e-bikes, like all motorcycles, are banned from certain downtown districts. There are also bans in place in small areas of Shanghai, Hangzhou and Beijing. Bans of "Scooter-Style Electric Bikes" (SSEB) were however cancelled and in Shenzhen e-bikes may be seen on the streets nowadays (2010–11).
In Norway, e-bikes are classified as ordinary bicycles, according to the Vehicle Regulation (kjøretøyforskriften) § 4-1, 5g. Hence, e-bikes are not registered in the Vehicle Registry, and there is no demand for a license to drive them. Still, there are constraints on the bicycle construction. The maximum nominal motor power output can be no more than 250 watts and the maximum performance speed of the vehicle when the engine is running is 25 km per hour (15 mph).[40] A function that reduces motor power when vehicle speed exceeds 25 km per hour is mandatory. However, if the motor is not running, the e-bike, or any other bike, answer only to the constraints of the ordinary speed limits.

In Manitoba Electric Bikes can be classified as a scooter or a moped/mobility vehicle depending on the power of the engine used and its top speed. If the engine on the Electric Bike is less than 50cc and it cannot exceed 50 km per hour the rider is not required to have a motorcycle licence or any specific training.[26] Electric Bikes can be driven by anyone with a Class 5 driver's licence in any stage of the graduated licensing process.[27] A Class 5 Learners Licence requires one to be age 16 (parents consent if under 18) and a visit to a licensing office to pass a vision test and a written knowledge test about the rules of the road and traffic signs.[28]

Depending on local laws, many e-bikes (e.g., pedelecs) are legally classified as bicycles rather than mopeds or motorcycles. This exempts them from the more stringent laws regarding the certification and operation of more powerful two-wheelers which are often classed as electric motorcycles. E-bikes can also be defined separately and treated under distinct Electric bicycle laws.
This was the first ebike I ever bought. I've since become a builder and make my own. But this was a really reliable vehicle. I used it everyday for transportation. The company sent me any part I needed. It's got a power motor on it so it's super reliable. I wouldn't hesitate to buy this bike especially if you're new into the ebike world. If your looking to have some real fun buy this bike.. If your looking to meet new people buy this bike. If looking to go more green buy this bike. This bike is so much fun you well want to ride all day. This bike should be twice the price . I love love love it .

Firstly there's a magnetically-fired locking pin in the rear wheel, triggered by kicking a button on the hub. This is fairly secure in itself and almost impossible to remove without destroying the bike. In London, we'd pair it with a more traditional bike lock so there's a more obvious visual deterrent, though a LED matrix screen on the frame does issue a warning to would-be tea-leafs.
