Photo: This typical electric bicycle, a Sanyo Eneloop (now discontinued), had a range of about 30–55 km (17–35 miles) and a top speed of around 24 km/h (15 mph). Note the 250-watt hub motor on the front wheel and the 5.7Ah lithium-ion battery pack (black, marked "Sanyo," just in front of the back wheel).

Great bike. Easy to assemble by yourself but if you have a rack let pros do it. No charge for that. Contacted the Addmotor people a few times and they got back quickly even on weekends. Great service. Bike is solid as a rock and excellent components. Only drawback is lack of fenders which I hope someone can manufacture. I would buy again in a nano second!
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.
Not all e-bikes take the form of conventional push-bikes with an incorporated motor, such as the Cytronex bicycles which use a small battery disguised as a water bottle.[44][45] Some are designed to take the appearance of low capacity motorcycles, but smaller in size and consisting of an electric motor rather than a petrol engine. For example, the Sakura e-bike incorporates a 200 W motor found on standard e-bikes, but also includes plastic cladding, front and rear lights, and a speedometer. It is styled as a modern moped, and is often mistaken for one.[citation needed]
Eight provinces of Canada allow electric power assisted bicycles. In all eight provinces, e-bikes are limited to 500 W output, and cannot travel faster than 32 km/h (20 mph) on motor power alone on level ground.[12] In Alberta prior to July 1, 2009, the limits were 750 W and 35 km/h (22 mph), but presently match federal legislation.[13] Age restrictions vary in Canada. All require an approved helmet. Regulations may or may not require an interlock to prevent use of power when the rider is not pedaling. Some versions (e.g., if capable of operating without pedaling) of e-bikes require drivers' licenses in some provinces and have age restrictions. Vehicle licenses and liability insurance are not required. Generally, they are considered vehicles (like motorcycles and pedal cycles), so are subject to the same rules of the road as regular bicycles. In some cases, regulatory requirements have been complicated by lobbying in respect of the Segway PT.
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]
Because e-bikes are capable of greater speeds for longer periods of time than standard bikes, you want extra control. Wider tires provide traction and some bump absorption with little penalty. You also want strong brakes to slow you (and all that extra weight) easily. It’s worth looking at the quality of the brakes and investing in bikes with better ones if you can.
Rose Heyer and Josie Tabor of Dept Tech, Department of State Information Center, the Secretary of State and the office of ROCK AND BORGELT, P.C., Attorneys at Law, 24500 FORD ROAD, SUITE 10 DEARBORN HEIGHTS, MI 48127-3106, determined electric bicycles are considered mopeds and need registered and licensed. In order to operate an electric bicycle on public streets, the driver must have a valid operator, chauffeur, or special moped license. However, not all electric bicycles are street legal unless they have the following safety equipment: operating brake light, headlight, and turn signals. The local police department must inspect the bicycle using Form TR-54 which is taken with proof of purchase to the DMV. The fee for the plate is $15 for a three year decal, whereas the fine for no decal is $150 per incident.
The Christmas day is coming soon, since I receive the bike, it's about a week, and I am satisfied with it! just as advertised, very powerful and good design. the most important point is that once the battery is FULL CHARGE, how far it can reach up to. I have a funny test, in the normal road(not in the dramatic slope or uphill), it can goes almost 44 miles. That is what I give 5 star for this bike! very powerful with reasonable price!
To operate the bike, you have to pedal for a second or so before the thumb throttle becomes active. This is often a cost and energy-saving measure designed into electric bicycles and scooters. Being able to start the motor from rest requires extra sensors and higher battery power. Starting the motor while it is in motion removes the need to install extra sensors in the motor (and thus removes one more possible failure or maintenance issue) and also eeks more range out of the battery by putting the energy intensive initial startup responsibility solely on the rider.
The BC Bike Show is the premier cycling and outdoors event in Western Canada and is happening in just 2 weeks on March 2nd and 3rd. We'll be there of course, and in addition to our exhibitor booth we'll also be hosting Cycle Stage to give more public presentations. On Saturday at 11:45 am we'll talk on how to navigate the various motor and battery options available for ebike retrofits, and on Sunday at 2pm we'll be doing a live demonstration of a regular bicycle being converted over to electric assist.
Having spent some quality time with Wing’s e-bike, I understand why so many people are excited about the growing popularity of electric-powered vehicles like bikes and scooters. They take a lot of the work out of getting from point A to point B, while retaining all of the joy. They can give you more confidence when navigating a treacherous city terrain that prioritizes cars over people. And let’s face it: bikes are cool, and always will be.
In the 1870s many cycling clubs flourished. They were popular in a time when there were not cars on the market and the principal mode of transportation was horse-drawn vehicles, such the horse and buggy or the horsecar. Among the earliest clubs was The Bicycle Touring Club, which has operated since 1878. By the turn of the century, cycling clubs flourished on both sides of the Atlantic, and touring and racing became widely popular. The Raleigh Bicycle Company was founded in Nottingham, England in 1888. It became the biggest bicycle manufacturing company in the world, making over two million bikes per year.[31]
Bicycles are popular targets for theft, due to their value and ease of resale.[113] The number of bicycles stolen annually is difficult to quantify as a large number of crimes are not reported.[114] Around 50% of the participants in the Montreal International Journal of Sustainable Transportation survey were subjected to a bicycle theft in their lifetime as active cyclists.[115] Most bicycles have serial numbers that can be recorded to verify identity in case of theft.[116]
But two other concerns are also front and center when it comes to biking: cost and convenience. Not many people have showers at their places of employment, and who wants to show up to work coated in sweat and stinky for the rest of the day? Electric bikes solve the convenience problem by making the process almost effortless; you can bike for miles—even up and down hills—without breaking a sweat.
Electric bicycles are not allowed in any public area, meaning an area where there is full or partial public access. Any kind of pedal assist, electric bike, scooter, moped or vehicle which has any form of propulsion, whether in full or as assist, other than human power, must be approved as either a car, motorcycle, van, truck, bus or similar. This makes pedelecs and tilt-controlled two-wheel personal vehicles illegal in all practical ways, as they cannot be registered as a motor cycle.[36]

The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885.[7][8][9] However, many details have been improved, especially since the advent of modern materials and computer-aided design. These have allowed for a proliferation of specialized designs for many types of cycling.
For many bikes, battery range is more important than total power (because they’re all pretty powerful). You want a bike that delivers a range long enough for your rides at the power levels you want. Most e-bikes will have three to five levels of assist that kick in anywhere from 25 percent of your pedal power to 200 percent. Consider how fast the battery takes to recharge, especially if you’ll be using your bike for long commutes.
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.

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.
"Moped" means a device upon which a person may ride which has two or three wheels in contact with the ground, a motor having a maximum power output capability measured at the motor output shaft, in accordance with the Society of Automotive Engineers standards, of two horsepower (one thousand four hundred ninety -two watts) or less and, if it is a combustion engine, a maximum piston or rotor displacement of 3.05 cubic inches (fifty cubic centimeters) and which will propel the moped, unassisted, on a level surface at a maximum speed no greater than thirty miles per hour; and a direct or automatic power drive system which requires no clutch or gear shift operation by the moped driver after the drive system is engaged with the power unit.

During nighttime operation, the bicycle must be equipped with a front headlamp, a rear-facing red reflector, and reflectors on the front and rear of pedals, and the bicycle or rider must have reflective surfaces on each side. Minn. Stat. §169.222, subd. 6. An electric-assisted bicycle can be equipped with a front-facing headlamp that emits a flashing white light, a rear-facing lamp that has a flashing red light, or both. The bicycle can carry studded tires designed for traction (such as in snowy or icy conditions).

And let’s not forget the economic advantages of owning an e-bike. The annual cost of running a new family car is, on average, about $9,000 per year. Running an electric bike costs around $400 per year. And while filling a gas tank costs around $30, recharging an electric bike battery costs only about 50 cents. A tank of gas may get you further, but not 60 times further!

The 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[4].
Some of the Rad Wagon’s (small) flaws became apparent once I added more weight to the bike. The integrated rear rack can attach various panniers, platforms, or baskets to cary your cargo, but I was most concerned with hauling my two kiddos to school. Riding the bike with my three year old was a cinch; he held on to the bars in the caboose (available as an accessory add-on) and enjoyed the view. Adding my very tall, almost seven-year-old daughter, however, was a bit more complicated.
Historically, materials used in bicycles have followed a similar pattern as in aircraft, the goal being high strength and low weight. Since the late 1930s alloy steels have been used for frame and fork tubes in higher quality machines. By the 1980s aluminum welding techniques had improved to the point that aluminum tube could safely be used in place of steel. Since then aluminum alloy frames and other components have become popular due to their light weight, and most mid-range bikes are now principally aluminum alloy of some kind.[where?] More expensive bikes use carbon fibre due to its significantly lighter weight and profiling ability, allowing designers to make a bike both stiff and compliant by manipulating the lay-up. Virtually all professional racing bicycles now use carbon fibre frames, as they have the best strength to weight ratio. A typical modern carbon fiber frame can weighs less than 1 kilogram (2.2 lb).

I am very pleased with the quality and performance of this electric bike. I find that the twist grip throtle works better for me than the peddle assist low, medium and high settings. It is not necessary to change out of high gear to climb most hills while peddling with the throttle also providing power. The shocks work well on dirt paths and the seat is comfortable. This bike goes maximum speed up to 19 mph on flat ground. I have
Power assisted bicycles are classified in two categories in Saskatchewan. An electric assist bicycle is a 2 or 3-wheeled bicycle that uses pedals and a motor at the same time only. A power cycle uses either pedals and motor or motor only. Both must have engines with 500 watt power or less, and must not be able exceed 32 km/h (20 mph), i.e., electric motor cuts out at this speed or cycle is unable to go this fast on a level surface. The power cycle has to meet the Canadian Motor Vehicle Safety Standards (CMVSS) for a power-assisted bicycle. The power cycle requires at least a learner's driving licence (class 7), and all of the other classes 1–5 may operate these also. The electric assist bicycle does not require a licence. Helmets are required for each. Both are treated as bicycles regarding rules of the road. Gas powered or assisted bicycles are classified as motorcycles regardless of engine size or if using pedals plus motor. Stickers identifying the bicycle's compliance with the Federal classification may be required for power cycles by some cities or municipalities.[31]
I discovered these downsides when, on my third day with the bike, I got a flat tire and had to carry it onto the subway with me for those last few miles back to my apartment. The cause of the flat is unknown; the bike mechanic who eventually fixed it didn’t see anything wrong with the rims. But the experience of trying to maneuver an almost 40 pound e-bike on and off a crowded subway car during rush-hour is not one I can recommend.
Louisiana Revised Statute R.S. 32:1(41) defines a motorized bicycle as a pedal bicycle which may be propelled by human power or helper motor, or by both, with a motor rated no more than one and one-half brake horsepower, a cylinder capacity not exceeding fifty cubic centimeters, an automatic transmission, and which produces a maximum design speed of no more than twenty-five miles per hour on a flat surface. Motorized bicycles falling within this definition must be registered and titled under Louisiana law. Additionally, a motorized bicycle operated upon Louisiana roadways or highways by a person fifteen years of age or older and producing more than five horsepower must possess a valid driver's license with a motorcycle endorsement and adhere to laws governing the operation of a motorcycle, including the wearing of approved eye protectors or a windshield and the wearing of a helmet. The statute also states that "Motorized bicycles such as pocket bikes and scooters that do not meet the requirements of this policy shall not be registered."

Today I’m looking at the Rattan Challenger 350W ebike. It can be found for under $680 at Amazon (after Electrek coupon code 5AIDO2GB) shipped and includes free assembly at a local bike shop. I assembled mine at home however in about 15 minutes with the graciously supplied in box hex tool and wrenches. It is pretty straight forward – the hardest part was bolting the front light on.
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. 

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 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.

The U.S. Consumer Product Safety Act states that electric bicycles and tricycles meeting the definition of low-speed electric bicycles will be considered consumer products. The Consumer Product Safety Commission (CPSC) has regulatory authority to assure, through guidelines and standards, that the public will be protected from unreasonable risks of injury or death associated with the use of electric bicycles.[61][62]

Pedelec is a European term that generally referred to an electric bicycle that incorporated a torque and/or a speed sensor and/or a power controller that delivered a proportionate level of assist and only ran when the rider pedaled. On the opposite side, a Noped is a term used by the Ministry of Transportation of Ontario for similar type vehicles which do not have pedals or in which the pedals have been removed from their motorized bicycle. Finally, Assist Bicycle is the technical term used to describe such a vehicle and Power-Assisted Bicycle is used in the Canadian Federal Legislation, but is carefully defined to only apply to electric motor assist, and specifically excludes internal combustion engines (though this is not the case in the United States).
In my research about ebikes and the law, I cannot begin to justify how often articles about the laws evolved into the various ways and techniques to sneak around public notice and be stealth with the your ebike. The goal is to ride fast and fun, stay away from public awareness, and ‘Fly under the Radar’. I have been there and I get the drift. Sales and production are up. Electric bike kits, DIY enthusiast, long distance commuters, and a general drive for value is raising the desire for more options for consumers, wanting speed for fun and function, while developing amnesia for the law. People want to ride their new ebikes, and have the same access to safe pathways as they did the week before on their 100% human bike. Rather than deal with the inevitable conflicts over access, behavior and perception within the general public, the typical user will try to blend in with the normal cycling community.
Electric Bicycles are defined by the California Vehicle Code [32][33]. In summary, electric bicycles are to be operated like conventional bicycles in California. There are several exceptions to this. A person must be at least 16 years old, and anyone riding an electric bicycle must wear a bicycle helmet. The e-bikes must have an electric motor that has a power output less than 1,000 watts, is incapable of propelling the device at a speed of more than 20 miles per hour on level ground, is incapable of further increasing the speed of the device when human power is used to propel the motorized bicycle faster than 20 miles per hour, operates in a manner so that the electric motor is disengaged or ceases to function when the brakes are applied, or operates in a manner such that the motor is engaged through a switch or mechanism that, when released, will cause the electric motor to disengage or cease to function.

In 2012, two e-bike advocates completed the first 4,000-mile (6,400 km) transcontinental e-bike tour from New York to San Francisco to advocate for e-bikes in major cities across the U.S.[81] Pedego Electric Bikes is the best selling brand in the U.S. Many e-bikes in the United States are standard bicycles converted using a kit. In general, the kits include the motor (the majority of which are hub motors built into the front or rear wheel), a speed controller, throttle (usually twist-grip or thumb throttle), necessary wiring and connectors, and a battery. Several U.S. companies offer conversion kits which also offer advanced lithium battery packs. Major manufacturers also offer complete e-bikes. Trek offers a line of e-bikes using the Bionx system in which the rider programs the controller to determine how much effort the motor will give in response to rider effort, from 25% up to 200% of the rider's power. This system ensures a minimum level of rider participation and is also used to comply with many European laws mandating partial human effort before the motor engages.
Because I am in an area with quite a lot of hills and steep inclines, some very steep, and the motor on the bike handles these hills effortlessly along with pedal assist. I will say I am not fit in anyway and there is no way I would have got up half of the hills I got up if it were not for the 250 watt motor on this bike, the low , medium and high pedal assist options are great and it is easy to assess which option you'll need depending on the hill.The battery was a lot heavier than I expected when holding it, feels like holiding a 3 LTR bottle of coca cola but I can forgive that
Electric bicycles are considered as "bicycles" under Montana law as the law defines bicycles in a two part definition where the first part of the definition describes a conventional bicycle propelled solely by human power and the second part of the definition describes a bicycle equipped with an independent power source for propulsion in addition to foot pedals to permit muscular propulsion. (Montana Code 61-8-102).[104]
Our hope is that this plug will become to motors in the 500-1500 watt power range what the 9pin Z910 became for the low power geared motors, with all motor manufacturers agreeing to the same pinout standard for easy swapping and interchangeability . We have an L10 version of the Phaserunner motor controller available now and will soon be expanding this to a Grinfineon offering as well.

Simple, convenient, cheap, and economical—bicycles are one of the world's favorite forms of transportation. But they're not for everyone. They can be hard to pedal up and down hills or with heavy loads, and elderly or disabled people may find them impossible to manage. In the last few years, a new generation of electric bicycles has begun to revolutionize our idea of environmentally friendly transportation. These new cycles have all the convenience of cars with all the simple economy of ordinary cycles. Let's take a closer look at how they work.
