It's what's inside your motor that sets it apart from the rest. Quality parts and assembly We've written here before about how to choose a motor, the different types of motors, the performance differences between motors, etc. But today I want to show you what makes our motors different from other hub motors. Today, harry is replacing the axle on a customer's direct-drive motor. The bike was crashed and the...

Stark Drive has always included a front head light by default at no charge for safety with the rear brake light being optional for those who needed this. Now we have reconfigured the homepage so that the rear headlight options i clearly visible and availble without needing to compllicate matters by adding it from our accessories page. We highly recommend a rear brake light no matter what motor you choose for Stark Drive.


Sure, you train hard and eat right, but there’s just one thing missing—an edge. The Amira gives you two. First, there’s the performance edge you get from its FACT carbon frame and tapered head tube. The combination results in responsive handling and true get-up-and-go accelerations. Then comes the psychological edge. The feeling that, when teamed up with a lightweight, high-performance machine, there’s no limit to what you can achieve together.
Though aside from the extra battery and abundance of included accessories, Riese and Muller’s use of a Gate’s belt drive means no shifting of gears, no greasy maintenance, and much higher durability. If you have the money to spend, Riese and Muller’s Delite nuvinci is one of the best on the market and an ebike we just couldn’t get enough of during our own tests.
A 2008 market survey showed that the average distance traveled in the Netherlands by commuters on a standard bicycle is 6.3 kilometres (3.9 mi) while with an e-bike this distance increases to 9.8 kilometres (6.1 mi).[79] This survey also showed that e-bike ownership is particularly popular among people aged 65 and over, but limited among commuters. The e-bike is used in particular for recreational bicycle trips, shopping and errands.[79]
Range is a key consideration with e-bikes, and is affected by factors such as motor efficiency, battery capacity, efficiency of the driving electronics, aerodynamics, hills and weight of the bike and rider.[36][37] Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes,[38] have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging.[39] This is useful for extending the range and the life of brake pads and wheel rims. There are also experiments using fuel cells. e.g. the PHB. Some experiments have also been undertaken with super capacitors to supplement or replace batteries for cars and some SUVS. E-bikes developed in Switzerland in the late 1980s for the Tour de Sol solar vehicle race came with solar charging stations but these were later fixed on roofs and connected so as to feed into the electric mains.[40] The bicycles were then charged from the mains, as is common today. While ebike batteries were produced mainly by bigger companies in past, many small to medium companies have started using innovative new methods for creating more durable batteries. State of the art, custom built automated precision CNC spot welding machines[41] created 18650 battery packs[42] are commonly used among Do-it-yourself ebike makers.
We’re an e-bike retailer based in Brooklyn, serving NYC, the rest of the US, and several other countries. Propel grew out of the recognition that e-bikes hold the potential to transform transportation as we know it. We’ve dedicated ourselves to bringing that transformation about since our founding in 2011. We’re pioneering a new industry standard that all the electric bikes we sell must meet, educating legislators so e-bike riders will be treated fairly under the law, and guiding consumers away from expensive pitfalls towards their perfect e-bike match.
Aluminium alloy frames and downtube mounted batteries with integrated motors provide a budget friendly introduction to these motor-assisted bikes, allowing riders who would struggle to keep up to enjoy the stamina of the pros. For those hard hitters, fully integrated battery and motors combine with lightweight alloy and carbon frames to deliver a ride that’ll take on the most demanding trails.
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.

However, if your friends are riding a bigger single battery pack, you’ll have to either choose to cut the ride short or conserve battery life while they run in turbo. If your local rides are short, fast blasts but you want to benefit from the ability to take on longer tours, the Sam2 could be for you. We love the Pro version, but it’s also available at a range of price points.

Our high performance electric bikes offer high power, predictable handling and near silent operation.  If your rides take you up steep single track trails or you just want a bike as light weight as possible, a mid drive system will offer the best hill climbing performance, lighter weight, and better weight distribution.  A hub motor system will offer the most reliable day in and day out operation, faster speeds, more power, and is a better overall platform for everyday commuting.
There are two main types of motor to suit different riding styles. The durable, "heavy duty" Direct-Drive motor, and the lightweight, efficient and fast "performance" geared motor. Electric Bike Motors, hub motors in particular, and electric bike batteries are what make electric bicycles go. Using a hand throttle you control the flow of electric current from the battery to the brushless motor. With an intelligent 20 Amp controller regulating the...
There are various kinds and classifications of electric bikes on the market, but the more common type is the Class 1, or pedal assist, bikes which have motor units that are activated by pedaling and are limited to lower speeds. In the US, Class 1 electric bikes, the type tested and reviewed here, are limited to a top speed of 20 mph and their motors are designed with a speed governor to regulate this. These types of e-bikes resemble modern mountain bikes, but they have significant battery packs and small motor units integrated onto and into the frame design. The e-MTB pedal-assist motor is typically built around the bottom bracket and provides varying levels of pedaling "support" directly into the drivetrain while the cranks are turning. Most drive unit systems offer several support settings that provide pedal assistance between 25% and 100% of the user's pedaling input.

Remember the freedom, fun, and sense of accomplishment that your first bike gave you? Well, these days, kids can share that excitement at even earlier age with our collection of kids' bikes and equipment. From toddler-friendly walk bikes to pint-sized helmets, we have everything you need to get your little ones away from the screen and out on their bikes.
E-bikes use rechargeable batteries, electric motors and some form of control. Battery systems in use include sealed lead-acid (SLA), nickel-cadmium (NiCad), nickel-metal hydride (NiMH) or lithium-ion polymer (Li-ion). Batteries vary according to the voltage, total charge capacity (amp hours), weight, the number of charging cycles before performance degrades, and ability to handle over-voltage charging conditions. The energy costs of operating e-bikes are small, but there can be considerable battery replacement costs. The lifespan of a battery pack varies depending on the type of usage. Shallow discharge/recharge cycles will help extend the overall battery life.

The LT or long travel line that Haibike is one of the most interesting developments in electric mountain biking in quite some time. I’ve chosen the FullSeven LT 4.0 because I wanted to show you another quality, low-cost option. The FullSeven line is built a little less aggressively than the AllMtn series, but still functions as a great all-around mountain bike for those riders who want to hit fire roads, and maybe the occasional single-track trail. The coolest thing about the LT line is that it costs exactly the same as the standard FullSeven line that comes with 120mm of travel. You can upgrade to 150mm on any FullSeven bike for no extra cost.
As my boys were growing up in the 2000s, we would bike together in local parks and I always dreamed of taking them on my favorite big rides when they reached their teenage years. But in 2012 I started getting sick and I didn’t know why. Two years later, after countless doctors visits, tests, and head scratching, I received some bad news from my doctor: somewhere in my adventures, I had contracted Lyme Disease. My life has never been the same.
By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle.[7] Schnepf's invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.[8]
