Electric-assisted bicycles are treated as human-powered bicycles, while bicycles capable of propulsion by electric power alone face additional registration and regulatory requirements as mopeds. Requirements include electric power generation by a motor that cannot be easily modified, along with a power assist mechanism that operates safely and smoothly. In December 2008, The assist ratio was updated as follow:
On the other hand, the battery doesn’t lock into the bike, which means you can’t just leave it on your bike when you park at the bike rack. Anyone could walk by and simply remove your battery. That seems like an oversight to me, though perhaps the designers assumed that such a small battery would just be easy to take with you. And it is. My wife could probably lose this battery in her purse.
Under the statute, mopeds must be registered. To be registered under Hawaii law a moped must bear a certification label from the manufacturer stating that it complies with federal motor vehicle safety standards (FMVSS). A moped must also possess the following equipment approved by the D.O.T. under Chapter 91: approved braking, fuel, and exhaust system components; approved steering system and handlebars; wheel rims; fenders; a guard or protective covering for drive belts, chains and rotating components; seat or saddle; lamps and reflectors; equipment controls; speedometer; retracting support stand; horn; and identification markings.

"Electric power-assisted bicycle" means a vehicle that travels on not more than three wheels in contact with the ground and is equipped with (i) pedals that allow propulsion by human power and (ii) an electric motor with an input of no more than 1,000 watts that reduces the pedal effort required of the rider. For the purposes of Chapter 8 of this title, an electric power-assisted bicycle shall be a vehicle when operated on a highway.[142]

I was hesitant to buy this battery at first due to the minimal amount of review feedback and poor English Grammer in the description. You never know. But, I ended up being very happy with it. Out of all the ebike components I ordered, this battery took the longest by far to get to me, about 11 days to reach me in North Central Florida. However, I believe that's because they ship from China which would also explain the poor grammar in the description. When you think about it, 11 days all the way from China is not bad. Considering the great price and inclusion of the rear rack, it really was worth the wait. I put it on a fat tire mongoose dolomite equipped with a 48v 1000w front hub motor. It was a very heavy bike to begin with, and my thinking was that having the motor in

There's much less of a sensation of the Electrified S2 'fighting back' once you hit 15.5mph, as well. That's helped by the automatic 2-speed gear box, although this does take some getting used to. Because its cogs are very different sizes you can end up with all sorts of cadence problems as it auto-shifts from high back to low. With practice you can avoid this, or of course you could in theory fit a second cog that's closer in size to the first.

I had gotten this to build an electric bike but I have never worked with wires before so I didn't realize that we needed to attach our own connectors to the wires. The person who I talked to at Joyisi was super nice and explained that to me and even offered to send me connectors for free. I had already ended up getting a different bike altogether though and so I just wanted to return the battery. But because I am returning it for my own reasons (as opposed to the battery being faulty), they would normally have me pay for return shipping and deduct the cost of shipping to me (which is a lot, because they are international) and the inspection fee from my refund, but they were super nice and offered to take on most of the costs and I would only have to pay for the return
IZIP ebikes is currently holding their huge annual sale. We know that IZIP makes high quality electric bikes that you can buy and ride with confidence. The current sale is a clearance of their 2018 models. One of the best ways to get a good deal on any bike is to buy a previous year’s model. Plus, IZIP offers free same-day shipping. So we have highlighted two of the best bargains in ebikes available from IZIP right now.

A lot has happened since we founded the very first eMTB specific magazine in 2013. In the beginning, manufacturers simply mounted electric motors on regular mountain bikes, more or more often than not, rather less successfully. Last year a lot of brands focused on the topic of battery integration. There are some exciting new trends and developments headed our way next season, which we take a closer look at below.
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.
The electric bike revolution has officially crossed into the arena of off-road motorbikes. For those who prefer riding in nature, Cake introduced a product which not only respects the environment but other riders, as well. Cake’s Kalk is a silent off-road motorbike that releases no emissions into the atmosphere. Additionally, its electric motor means no gear changing or clutching — a silent motorbike that won’t detract from the experience of others. Perhaps the best part is Cake avoided any sacrifice in performance. The Kalk reaches speeds of fifty miles per hour and features three distinct driving modes: Discover, Explore, and Excite.
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.
Would an e-bike that used a trailing generator to power the electric motor still be considered an e-bike? The purpose of the generator is allow greater distances to be traveled and all day riding. The gen-set that I am looking at uses a 49 cc gas engine with a 12 volt generator, this would be from the ground up build using a 1 hp electric motor. This seems to stay within the state laws of AZ. where I reside. Thanks for your thoughts.

The bicycle was recognized by 19th-century feminists and suffragists as a "freedom machine" for women. American Susan B. Anthony said in a New York World interview on February 2, 1896: "I think it has done more to emancipate woman than any one thing in the world. I rejoice every time I see a woman ride by on a wheel. It gives her a feeling of self-reliance and independence the moment she takes her seat; and away she goes, the picture of untrammelled womanhood."[74]:859 In 1895 Frances Willard, the tightly laced president of the Woman’s Christian Temperance Union, wrote A Wheel Within a Wheel: How I Learned to Ride the Bicycle, with Some Reflections by the Way, a 75-page illustrated memoir praising "Gladys", her bicycle, for its "gladdening effect" on her health and political optimism.[72] Willard used a cycling metaphor to urge other suffragists to action.[72]
But in Great Britain, the European Union definition is applicable, and the tighter restrictions of the Electrically Assisted Pedal Cycle Regulations 1983 (including a 200 kg weight limit on solo bicycles) were removed on 6 April 2015 by the Electrically Assisted Pedal Cycles (Amendment) Regulations 2015.[48][49] Riders must be at least 14 years of age, but no driving licence is required.
Many newer or smaller companies only design and market their products; the actual production is done by Asian companies. For example, some 60% of the world's bicycles are now being made in China. Despite this shift in production, as nations such as China and India become more wealthy, their own use of bicycles has declined due to the increasing affordability of cars and motorcycles.[102] One of the major reasons for the proliferation of Chinese-made bicycles in foreign markets is the lower cost of labor in China.[103]
In the theoretical electric bike we considered up above, we had the dynamo/motor driving the back wheel directly, simply by pressing on the tire. Most electric bikes work a different way. They have compact electric motors built into the hub of the back or front wheel (or mounted in the center of the bike and connected to the pedal sprocket). Take a look at the hub of an electric bike and probably you'll see it's much fatter and bulkier than on a normal bike. You can read more about how these motors work in our main article about hub motors.

To qualify as an electric-assisted bicycle under state law they need to have a seat and fully operable pedals for human propulsion, meet federal motor vehicle safety standards, an electric motor that has a power output of not more than 1,000 watts, maximum speed of not more than 20 mph (electric motor and human power combined), disengages or ceases to function when the vehicle’s brakes are applied, two or three wheels 

In the Netherlands all train stations offer free bicycle parking, or a more secure parking place for a small fee, with the larger stations also offering bicycle repair shops. Cycling is so popular that the parking capacity may be exceeded, while in some places such as Delft the capacity is usually exceeded.[64] In Trondheim in Norway, the Trampe bicycle lift has been developed to encourage cyclists by giving assistance on a steep hill. Buses in many cities have bicycle carriers mounted on the front.
For those who missed seeing it live, we've also uploaded a youtube video of our live demonstration of a regular bike being converted over to electric assist. We hope that this helps demystify the process for some considering their first kit purchase. It was a fun opportunity as the owner of the bike was at the show and could ride it away the next day.

They also served to teach the industrial models later adopted, including mechanization and mass production (later copied and adopted by Ford and General Motors),[76][77][78] vertical integration[77] (also later copied and adopted by Ford), aggressive advertising[79] (as much as 10% of all advertising in U.S. periodicals in 1898 was by bicycle makers),[80] lobbying for better roads (which had the side benefit of acting as advertising, and of improving sales by providing more places to ride),[78] all first practiced by Pope.[78] In addition, bicycle makers adopted the annual model change[76][81] (later derided as planned obsolescence, and usually credited to General Motors), which proved very successful.[82]
E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque, and others, like Bosch’s Active Line, are nearly silent. But, generally, all four make good options. Look for motor output (in torque), which will give you an idea of total power. Just like car engines, more torque equals more power off the line and more boost to your pedaling. But watt hours (Wh) is perhaps a more important figure to use—it takes into account battery output and life to give a more accurate reflection of power (higher Wh equals bigger range).
I did my commute a few times with the Rattan and while I would never give up my “bike store” e-bike for this, it was a worthy substitute. It never gave out on the big hills, nor did I have to brake because I felt the bike was falling apart. The frame is a little small for 6-foot me but it only comes in one size. I really miss the low rolling drag of having road tires however and this is something that both Rattan and Ancheer could improve upon. I don’t think many people are seriously off-roading with these bikes. Put some Schwalbe Big Bens on there!
An itinerant wordsmith with a broad constellation of interests, Lydia Chipman has turned iconoclasm into a livelihood of sorts. Bearing the scars and stripes of an uncommon diversity of experience -- with the notable exceptions of joining a religious order or becoming an artist -- she still can’t resist the temptation to learn something new. Lydia holds a master of arts in English from Georgia Southern University, and a bachelor of arts cum laude in integrative studies from Clayton College. Her expertise is in the areas of robotics, electronics, toys, and outdoors and computer equipment.
Whether squeezing onto the 4 train or pedaling through Lower Manhattan, I notice a few curious glances at the bike with the big battery in the center of the frame. This is not surprising; e-bikes are huge practically everywhere but the US. According to the latest figures from the Confederation of the European Bicycle Industry, e-bike growth in the UK is up from 40,000 units in 2016 to 63,000 in 2017.
Hi Levi, I’m not super familiar with Minnesota or the age limits on ebikes but Pedego just launched one specifically for younger riders (it goes a little slower). Many ebikes let you program a top speed and I feel like this is one area where you can decide as a parent. When I was 13 I had a moped and fixed up a goped with my Grandpa on his farm so… I guess it might be a family decision?

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")
Earlier UK regulations required that the motor has an average power output limited to 200 W (250 W for tricycles and tandems) and weight limited to 40 kg (60 kg for tricycles and tandems). These regulations must come in-line with the EU regulations by (find deadline). For models sold before June 2003, e-bikes conforming to the speed, weight and power limits may also be considered pedal cycles. Electric bikes with higher power outputs, or those not meeting the "pedelec" definition are now treated as motorcycles and require a license.
I converted my Kona Dew Deluxe to electric with a controller and 1000 watt front wheel. The SLA batteries I tried initially were _functional_, but the bike had a range of about 6 miles @ approx. 50% throttle use. Since upgrading to the Joyisi pack, the utility of the bike has increased exponentially. I need to add a better gauge so I can drain the battery more fully between charges, but I'm getting at least 20 miles per charge, including some very aggressive uphill segments. On flat ground, the battery powers the bike to approx. 35MPH; even on really steep hills with minimal pedal assist, I do at least 15MPH. Biking 15MPH uphill with little/no effort is EPIC.
To be honest, this bike is really designed for city commuters or kids riding around the suburbs. The fact that it’s foldable will let you carry it on the bus, on the train or even on the plane. It’s just not designed for heavy riding, long distances or tough terrains. If you want something sleek and fabulous at a fraction of the cost of most other e-bikes, this baby’s for you.
An electric bicycle is a bicycle with an electric motor used to power the vehicle, or to assist with pedaling. In many parts of the world, electric bicycles are classified as bicycles rather than motor vehicles, so they are not subject to the same laws as motor vehicles. Electric bicycles are one type of motorized bicycle. However, electric bicycles are defined separately and treated as a specific vehicle type in many areas of legal jurisdiction.
Built around a heavy-duty alloy frame, the GSD eschews many of the traits of other cargo bikes: long wheelbases, bigger wheels, and especially, an unwieldy ride. Yet it boasts an extensive capacity, nimble handling—even fully loaded, thanks to a short wheelbase and 20-inch wheels—and enduring range in a package not much bigger than most non-cargo e-bikes. The stout frame holds a 250-watt Bosch motor that gives up to 275 percent of your power back to the pedals and reaches 20 mph. The GSD has room for two battery packs, extending the batteries’ combined range to a claimed 150 miles and making the Tern one of the longest-lasting e-bikes on the market. A laundry list of accessories and a (claimed) 396-pound carrying capacity round out the GSD’s status as an epic day-tripper. 

A KS LEV Integra dropper post, 130mm of front and rear travel, 27.5-inch wheels, and trail-grabbing 2.8-inch tires make this pedal-assist mountain bike a great option if you want to climb farther to shred longer, but don’t want to lug your bike uphill for ages. The 250-watt motor, placed slightly farther forward than most other bikes to optimize weight distribution and handling, provides a nice boost so you can enjoy the ride up and not be too gassed when you get to the top.

In built up cities around the world, urban planning uses cycling infrastructure like bikeways to reduce traffic congestion and air pollution.[59] A number of cities around the world have implemented schemes known as bicycle sharing systems or community bicycle programs.[60][61] The first of these was the White Bicycle plan in Amsterdam in 1965. It was followed by yellow bicycles in La Rochelle and green bicycles in Cambridge. These initiatives complement public transport systems and offer an alternative to motorized traffic to help reduce congestion and pollution.[62] In Europe, especially in the Netherlands and parts of Germany and Denmark, bicycle commuting is common. In Copenhagen, a cyclists' organization runs a Cycling Embassy that promotes biking for commuting and sightseeing. The United Kingdom has a tax break scheme (IR 176) that allows employees to buy a new bicycle tax free to use for commuting.[63]

The days when eMTBs were defined solely by the power of their motors and the size of their batteries are over. Riding performance has become the most important metric. In that pursuit, manufacturers are increasingly developing eMTBs with less power and battery capacity, which in turn handle more like regular mountain bikes. FOCUS started this movement some time ago with its Project-Y concept and later presented the FOCUS RAVEN² PRO, the first production model in a new category of bikes. However this sporty ride only convinced a handful of riders. Meanwhile, Lapierre and BULLS have both announced full-suspension trail bikes featuring the lightweight FAZUA motor for next year. It remains to be seen how many other brands will jump on board this bandwagon – but the rumour mill has already started rumbling. Moreover, it is only a matter of time before the next motor manufacturer will release its own small, lightweight motor.
"Electric-assisted bicycle" means a bicycle with two or three wheels, a saddle, fully operative pedals for human propulsion, and an electric motor. The electric-assisted bicycle's electric motor must have a power output of no more than one thousand watts, be incapable of propelling the device at a speed of more than twenty miles per hour on level ground, and be incapable of further increasing the speed of the device when human power alone is used to propel the device beyond twenty miles per hour.[66]
Every inch of the bike is thought through, from how the simple, rugged battery connection to the hydraulic disc brakes to the tire choice, to the adorable little bell. The custom battery shape works aesthetically with the frame and is not some obtrusive piece strapped to the down tube of the bike. By putting it down low, it also adds to the stability of the bike, making it handle like a dream, regardless of speed.
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. (AB441, amending NRS 480, 482 and other sections)

Speaking of which, if you're used to non-electric cycles, be aware that e-bikes are heavy and capped at 25kph or 15.5mph. In many cases, that means the bike starts to feel like its actively fighting against you, if you try to push the speed higher than that by pedalling. That's especially true with heavier bikes, for obvious reasons, and can take a while to get used to.

GPS Firmware: This net update will be much appreciated by people who have a GPS Analogger device with their CA3. With a simple hardware modification to the Analogger circuit, the GPS data will be transmitted from your existing TRS cable back to the Cycle Analyst. You can then see the time of day, your elevation, position, and direction all on the CA3 screen. The firmware also features additional custom views on the main screen, allowing you to replace or toggle the battery voltage with any of these new parameters to get just the display you are after.
I would advocate you ride legal within the laws of your state. I would also look into some kind of liability rider or umbrella policy with your home owner’s policy, which covers your personal liability and theft. Get your bike registered; wear your helmet, eye protection, whatever is required by state law so that if an accident occurs and you are at fault, there is no legal recourse. Even if you own a 750W/20mph ebike that meets the definition of a bicycle, any at-fault cyclist may still be denied coverage by stingy insurance companies who want to support their clients. Your health insurance will usually cover your medical bills, but the costs of an expensive ebike may be lost.
