An e-bike is identified as a "motor assisted cycle" (MAC) in British Columbia, which differs from electric mopeds and scooters, which are "limited-speed motorcycles." Motor assisted cycles must: have an electric motor of no more than 500 W; have fully operable pedals; not be capable of propelling the device at a speed greater than 32 km/hr [19.9 mph]. The engine must disengage when (a) the operator stops pedaling, (b) an accelerator controller is released, OR (c) a brake is applied. A driver's license, vehicle registration, and insurance are all not required. A bike helmet must be worn.[22]
An affordable GPS enabled bike security alarm device with text and email updates, runs on the 2G Verizon network to send notifications about location and status, includes iPhone, Android and web apps to control the device, track, and download ride data. Mounts to any standard bottle cage bosses if there is enough horizontal room, the device is 10" long and 3/4" thick with rubberized contacts to reduce vibration, rear rack and quick clamp mounting accessories available to work with just about any bike...
Gulas boast that their Pi1S is the world’s fastest e-bike achieving a maximum speed of 71mph (115km/h) while pedal assisted.  You won’t see one of these in the UK without a licence plate because any electric bike having motor assistance above 15.5mph has to be registered as a road vehicle.  This 38bhp electric bike weighs in at 128kg, with two separate battery options; a 6.5 kWh battery giving around 75 miles per charge, and a 10 kWh boasting 120 miles per charge range.  Pricing starts at £17,500.  Visit www.gulas.bike for more information or to book a test ride.
Saddles also vary with rider preference, from the cushioned ones favored by short-distance riders to narrower saddles which allow more room for leg swings. Comfort depends on riding position. With comfort bikes and hybrids, cyclists sit high over the seat, their weight directed down onto the saddle, such that a wider and more cushioned saddle is preferable. For racing bikes where the rider is bent over, weight is more evenly distributed between the handlebars and saddle, the hips are flexed, and a narrower and harder saddle is more efficient. Differing saddle designs exist for male and female cyclists, accommodating the genders' differing anatomies and sit bone width measurements, although bikes typically are sold with saddles most appropriate for men. Suspension seat posts and seat springs provide comfort by absorbing shock but can add to the overall weight of the bicycle.
Introduction A quick of note of my experiences riding a Moustache Dimanche eBike, kindly provided by Fully Charged, on a spectacular 4 day trip, coast-to-coast across Italy. Overall, an amazing experience in terms of the quality of the ride, the scenery and the new experience of quite painless climbing of the many steep hills. I … Continue reading The joys of crossing Italy coast 2 coast on an eBike – by Andreas Credé
As electric bike options continue to expand, more brands are integrating the battery more seamlessly. That makes them look sleeker (and more like a real bike). Batteries are expensive, so make sure there’s a good way to lock the battery to your bike if you’ll be keeping it outside. Overall weight is important. Some battery and motors can add 15 pounds or more to the bike. With assist, you won’t feel that much when you’re riding, but you will if you have to carry your bike up stairs or lift it onto a bike rack.
Template:Cleanup Template:Split Many countries have Electric bicycle laws which legislated to one extent or another the legality of Electric Bicycles. Countries Like the United States and Canada have Federal regulations governing the safety requirements and standards of manufacture. Other countries like the Signatories of the European Union have agreed to wider ranging legislation covering use and safety for what they term EPAC(Electric pedal assisted cycles).
The recommendation depends a lot on what you plan to use the bike for and how you plan to ride. That said, I would recommend at least a 750 (if not 1,000) watt motor, and, if you want reasonable range, 48 or 52v cells with a minimum rating of 19ah. For shorter rides, you can use a smaller battery. Multiply battery voltage by amp hour rating to get battery watt hours. Divide the watt hours by the motors power rating to get a general idea of how many hours of heavy use you might get. I’d also recommend a mid drive as opposed to a hub drive, or to find a hub drive wheel rated to take your and the bicycle's combined weight.
Electric motor assisted bicycles have been banned in the State of New York and are not permitted for on-road use.[50][51] It appears the only known allowance of an electric bicycle is if it is an electric powered moped, at this time. There is a proposed bill to allow ebikes. As of May 2009, Bill A2393("Defines the term electric assisted bicycle") has been passed in the NY State Assembly[52] and its corresponding Bill S4014, sponsored by Senator Thomas Morahan, is before the NY State Senate.[53]
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.

Another style is the recumbent bicycle. These are inherently more aerodynamic than upright versions, as the rider may lean back onto a support and operate pedals that are on about the same level as the seat. The world's fastest bicycle is a recumbent bicycle but this type was banned from competition in 1934 by the Union Cycliste Internationale.[43]


Most consumers want an e-bike that will accommodate its motor without being too cumbersome and will remain stable in spite of its electronic components. Some consumers want only the most basic of e-bike features, including lights, a cargo rack/basket, and a water bottle holder. Others are focused more heavily on safety features, such as brake type. And still others are concerned with convenience and portability.

One of the profound economic implications of bicycle use is that it liberates the user from oil consumption.(Ballantine, 1972) The bicycle is an inexpensive, fast, healthy and environmentally friendly mode of transport. Ivan Illich stated that bicycle use extended the usable physical environment for people, while alternatives such as cars and motorways degraded and confined people's environment and mobility.[105] Currently, two billion bicycles are in use around the world. Children, students, professionals, laborers, civil servants and seniors are pedaling around their communities. They all experience the freedom and the natural opportunity for exercise that the bicycle easily provides. Bicycle also has lowest carbon intensity of travel.[106]
This little bike is great I weight like 175 and it's just great it can go up hills and it's an awesome little bike for NYC cops give me no issues and with a phone mount you can see your speed and battery life you have left... It's just a great bike nice and light I can pick up with one hand and it folds. The only cons I would say is I wish the battery lasts longer I get around 6.5 miles at full throttle at varying terrain and the horn is weak, I installed an air horn on my bike
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. On power alone the bike goes about 15 to 18 mph on flat ground. I have been able to go about 24 miles using combined power and peddling before running out of battery. I assembled this myself.
Oklahoma defines an Electric-Assisted Bicycle in 47 O.S. 1-104 [122] as "Two or three wheels; and Fully operative pedals for human propulsion and equipped with an electric motor with a power output not to exceed one thousand (1,000) watts, incapable of propelling the device at a speed of more than thirty (30) miles per hour on level ground, and incapable of further increasing the speed of the device when human power alone is used to propel the device at a speed of thirty (30) miles per hour or more. An electric-assisted bicycle shall meet the requirements of the Federal Motor Vehicle Safety Standards as set forth in federal regulations and shall operate in such a manner that the electric motor disengages or ceases to function when the brakes are applied." 

Despite the illegal status in the state of New York, enforcement of this law varies at the local level. New York City enforces the bike ban with fines and vehicle confiscation for throttle activated electric bikes.[113] However, Mayor Bill de Blasio has recently changed the city's official policy to legalize pedal-assist electric bikes that have a maximum speed limited to 20 mph. [114] Contrarily, Tompkins County supports electric bike usage, even providing grant money to fund electric bike share/rental projects.[115]

In a friction drive motor, a small, solid wheel rotates against the side of the tire in order to drive it. The first motorcycles used the same concept, with a motor mounted above the front wheel. The problem is that the drive rubs at the side of the tire. It's inefficient, and it quickly wears the sidewall away. Tires need to be replaced every couple hundred miles. For this reason, you'll seldom see electric bikes with this type of drive anymore.
To operate a motorized/electric-assisted bicycle on the streets or highways a person must have a valid driver’s license or a motorized bicycle permit. A person under the age of 16 operating a motorized/electric-assisted bicycle under a motorized bicycle permit is subject to restrictions of no passengers (a parent or guardian my ride if the motorized/electric assisted bicycle is equipped with a seat and footrests for a passenger), no night driving, driving on any highway marked as an interstate, must wear a helmet, foot rests for passengers (if designed for passenger(s). A motorized bicycle permit is available to persons of at least 15 years of age who have passed the motorized bicycle test or passed a motorized bicycle course. A motorized bicycle would need the same coverage as a motorcycle would in this state. An electric-assisted bicycle would not need coverage.

The body is made from light and durable aluminum. The handlebar comes with simple controls to let you accelerate, brake, monitor battery life, operate headlights and of course…sound the horn. There’s even an USB point that will let you charge your iPhone or Android on the go. The bike can reach a top speed of 10mph. Feel the wind in your hair as you zoom up and down hills and past all that city traffic…
When last checked, no E-bikes satisfied this requirement, so ebikes cannot be registered in New Jersey.[108] However, NJ Bill A2581, introduced March 22, 2010, would permit the use of low-speed electric bicycles upon the roadways and bicycle paths in NJ, where a low-speed electric bicycle is defined as a two-wheeled vehicle with fully operable pedals for human propulsion and an electric motor of less than 100 pounds and 750 watts, whose maximum speed on a paved level surface is less than 20 miles per hour.[109] The bill has been referred to the state's Assembly Transportation, Public Works and Independent Authorities Committee.[110]

Even with cheaper or heavier bikes, once you accept that you are really meant to pedal gently and let the motor do the work, non-speed freaks will get into it. E-bikes are great for commuting and for places that aren't pancake flat. They'll pull you away from the lights quickly, iron out hills and stop you getting sweaty, so you can bin the Lycra and ride in jeans, a suit, or a winter coat.
1. Eligibility: Sweepstakes (the "Sweepstakes") is open only to those who sign up at the online sweepstakes page and who are at least 18+ years old at the time of entry. The sweepstakes is open to the legal residents of the Contiguous USA and Canada and is void where prohibited by law. Employees of Electric Bike Technologies INC. (the "Sponsor") their respective affiliates, subsidiaries, advertising and promotion agencies, suppliers and their immediate family members and/or those living in the same household of each are not eligible to participate in the Sweepstakes. The Sweepstakes is subject to all applicable federal, state and local laws and regulations. Void where prohibited.

If you have dynamo-powered bicycle lights, you already own an electric-powered bicycle! Consider: as you pump your legs up and down on the pedals, you make the wheels rotate. A small dynamo (generator) mounted on the rear wheel produces a tiny current of electricity that keeps your back safety lamp lit in the dark. Now suppose you could run this process backward. What if you removed the lamp and replaced it with a large battery. The battery would kick out a steady electric current, driving the dynamo in reverse so that it spun around like an electric motor. As the dynamo/motor turned, it would rotate the tire and make the bike go along without any help from your pedaling. Hey presto: an electric bike! It may sound a bit far-fetched, but this is more or less exactly how electric bikes work.


All classes of electric-assisted bicycles may be operated on a fully controlled limited access highway. Class 1 and 2 electric bicycles can be used on sidewalks, but Class 3 bicycles "may not be used on a sidewalk unless there is no alternative to travel over a sidewalk as part of a bicycle or pedestrian path."[143] Generally a person may not operate an electric-assisted bicycle on a trail that is designated as non-motorized and that has a natural surface, unless otherwise authorized.
While falling gas prices have temporarily halted years of gains in the number of bicycle commuters, more and more of us are using the bicycle to get around. It’s economical, provides good exercise, and is much cheaper than owning a car. But unless you’re in really good shape, you aren’t going to get very far. Enter the electric bike: a glorious new contraption allows us to get around without having to worry about arriving at our destinations a sweaty mess.

Class 1 makes great inroads to establish set boundaries for off road/natural surface trail access for eMountain bikes. There is fierce resistance from some mountain biking purists to allow ebikes on trails. BPSA and IMBA have done good work to justify the impact of class 1 ebikes on natural surface trails, and eliminate the wear-n-tear argument, though IMBA members are not 100% on board.


Under the Guide Section of EBR, Court has written a full article, dedicated to the new classification approach, which was initiated by the BPSA (Bicycle Product Suppliers Association), supported by PeopleForBikes, and then Calbikes. The initiative was meant to be pro-active with ebike legislation, to establish self-imposed, measurable, distinct classes of electric bikes before states start hearing about anecdotal problems and potentially overreact to the technology with wide sweeping limitations.
Electrically-assisted cycles are usually classified as either pedelecs or e-bikes. Under European Union regulations adopted in the UK in June 2003, only power-assisted cycles meeting the pedelec classification are considered to be pedal cycles. The maximum power allowed in the European Union for (pedelec) electric bicycles is 250 W, with a maximum assisted speed of 25 km/h.[15]. To meet the pedelec specification the electric motor must be activated by the rider's pedalling effort and the power must cut out completely whenever the rider stops pedalling. Control of the motor by pedalling is often the key difference between a pedelec and e-bike.
As with all these bikes, the assisted speed is capped at 15mph, but unlike some of them, the Gtech eBike City or its identical (spec-wise) sibling the eBike Sport (this just has a standard frame rather than a step-through one) is light and agile enough for you to be able pedal harder without feeling like the weight is fighting you back down to 15mph. You can even, at a push, use it without the motor on flatter roads.
As of May 19, 2009, Nevada amended its state transportation laws to explicitly permit electric bicycles to use any "trail or pedestrian walkway" intended for use with bicycles and constructed with federal funding, and otherwise generally permits electric bicycles to be operated in cases where a regular bicycle could be. An electric bicycle is defined as a two- or three-wheeled vehicle with fully operable pedals with an electric motor producing up to 1 gross brake horsepower and up to 750 watts final output, and with a maximum speed of up to 20 miles per hour on flat ground with a 170-pound rider when powered only by that engine.[106]
A local unit of government having jurisdiction over a road or bikeway (including the Department of Natural Resources in the case of state bike trails) is authorized to restrict e-bike use if: the use is not consistent with the safety or general welfare of others; or the restriction is necessary to meet the terms of any legal agreements concerning the land on which a bikeway has been established.

The other is our first foray into the larger 45mm wide motor series, similar to those sold by MXUS, QS, Leafbike etc. as 3KW or 5kW hubs. We got these made up to properly fit either a standard 135mm dropout with a single speed freewheel, or a 150mm dropout with a 7-8 speed freewheel and some spacers. As expected from Grin they are sealed, include a 10K thermistor for temperature sensing, and have a disk hole injection port for Statorade, and are hubsink compatible. Check out the performance on our simulator both with and without statorade. Unlike so many other direct drive motors, both of these have the proper alignment for disk rotor position and room for disk calipers without shimming things out.
Nevada Electric Bicycle (NRS 482.0287) Bicycle 20 (motor only on the flat with 170LB rider, undefined if pedal assist is allowed to go faster) 750W (it is undefined as to whether this is input or output power, but in the USA, motors are rated on output power at the shaft) No none (use caution here because of "reckless endangerment" laws) no (not a "motor vehicle")
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.
I'm one of the hardcore cyclists at Ars, along with Jay Timmer and his new-as-of-last-fall road bike as well as copyeditor Kerry Staurseth. I love cycling, and it was a major factor in my dropping 120lb over a 12-month period starting in the summer of 2009. My daily rider/errand-runner is a 1998 Gary Fisher Marlin mountain bike. For longer rides, I use my 2009 Trek XO2 cyclecross bike. I've made a few modifications to it, including removing the bumpy cyclecross tires and swapping out the front 46-tooth chainring for a 50-tooth one. I went with a cross bike over a road bike because I'm still a Clydesdale, and I like the slightly longer wheelbase of a cross bike. I've also briefly owned a 2011 Trek Madone 5.9, which I sold not long after I bought it due to severely screwing up my right knee.
For a more stylish ride, cast your eyes over the Coboc Rome. It's a full-size bike, with gorgeous stylings, and large wheels that let you pick up plenty of speed on the road. It has a fuss-free approach too, with its automatic motor assistance -- all you need to do is get on and ride. It's very much like any fixed gear bike you'll see on the streets, but with the additional motor, it's less effort to get about.
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]
Brock had been running his esoteric shop on Cambie St. for over 30 years, pioneering the sale and production of recumbent bikes, tricycles, velomobiles, unicycles, and of course electric bicycles well before any of these things were popular. He was dabbling with early ebike conversions in the 1990's when we were still in grade school and has been for many years one of the few shops always willing to say yes to electric retrofits. We hope to still see him riding around streets of Vancouver in a white velomobile. 
In summary, federal law trumps all States’ laws. That is true with bicycle law, too. States cannot constitutionally pass legislation that reduces or eliminates Federal laws, they can only pass legislation that enacts additional (tighter) restrictions on its people. States can’t define an ebike a bicycle if greater than 750W/20mph, nor can they define an ebike a motor vehicle if less than the Federal Government’s limit of 750 Watts and a top electric-powered speed of 20 MPH.3This is the Federal definition of a low speed electric bike, which equates it to a bicycle.
Hmm, that’s unfortunate. I actually have a doctors note that I carry along which recommends the use of an assisted bicycle. I ride thoughtfully and have never been asked to show it. I cannot comment on the federal parks, perhaps they are not aware of the federal law classifying electric assist bikes that perform at or below 20 mph and 750 watts as bicycles. Having a note and this information would be a good response if you were questioned.

In addition to this, however, you’re going to want to invest in additional safety gear if you don’t want to end up as a statistic. This must include a helmet, as your skull is incredibly vulnerable when moving along at biking speeds. There are even some helmets that have lights and turn signals integrated into their design, giving you greater visibility for drivers.
Beginning January 1, 2017, manufacturers and distributors of electric bicycles will be required to apply a label that is permanently affixed, in a prominent location, to each electric bicycle, indicating its class. Should a user "tamper with or modify" an electric bicycle, changing the speed capability, they must replace the label indicating the classification.
It’s a topic that many eMTBers are interested in: fast charging. What has long been a reality with electric cars is now also being partly improved for ebikes with high amperage chargers. Bosch has presented a 6A charger this year that can charge a 500 Wh battery in 3 hours, more than a third faster than the standard charger. The new benchmark next year, however, will probably be the 10A charger presented by Haibike and BMZ. It is claimed to be capable of charging a 630 Wh battery in just 1.5 hours.

If you are a regular bicyclist who wants to add some excitement to your rides or wants some help with those hills, a full sized electric bike is the way to go. If you are considering a bike as a means of transportation more than an outlet for amusement, then a smaller, folding electric bike is the convenient choice. In each category, consider the speed and range you want, as these factors impact price.
Awesome little machine. My wife loves it. She gets so many people asking her where she got it and that they want one too. I have an 6 speed/ electric bike but she is not comfortable riding it or any bike for that matter but she’s totally comfortable and confident when she rides the swag. Great product. Exceptional quality and cool looking too. You can’t go wrong with this machine for your wife or daughter or whomever wants to ride but doesn’t want anything bulky or to heavy.
It should be noted that the definition as written does not define the power of the motor in Watts as is conventionally done for electric bicycles but rather in brake horsepower. Thus for an electric bicycle, motor kit, or electric bicycle motor that is not rated by the manufacture in brake horsepower but rather in Watts a conversion must be made in the units a conversion which is not given in the code of the law and thus the court will have to consider a factor of conversion that is not directly encoded in the law. Industry standard conversion for Watts to horsepower for electric motors is 1 horsepower = 746 watts.[105] Acceptance of that conversion factor from industry, however, as interpretation of the law is subject to the process of the courts since it is not defined specifically in the law.

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!
