Twice the speed - with half the effort, Optibike has the power. On a test ride in Boulder Colorado, a fit road cyclist was able to climb the notorious Old Stage Road at 10 MPH sitting down with an easy spin on the Optibike. On his ultra light road bike, he had to stand and grind all the way to go 5 mph!!! Twice the speed - half the effort, Optibike has the power.

The second type of electric bike is a much smaller, often foldable unit designed for convenient urban (or suburban) commuting and for easy storage in minimal space. These compact electric bikes are perfect for trips of a few miles, and many are small and lightweight enough to be carried onto trains or buses, allowing their rider to make use of multiple types of transportation in a single trip, and to store their bike in a closet or even under a desk at work, at school, or at home.
Because they’re electrically powered, e-bikes sit in a bit of a gray area between bicycles and motorcycles. While some states have enacted specific legislation to state where electric bikes can and can’t be ridden, in other states outdated laws mean they’re regulated as a moped or motor vehicle which can cause confusion over registration requirements, access to cycling infrastructure and how old you have to be before you can ride one.
The first functioning electric motor was displayed in the early 19th century, though the device constructed by British scientist Michael Faraday did little more than swirl a wire around a magnet when an electric charge was introduced. Still, the concept proved that electricity could do work. Functional electric motors would follow in many forms after that achievement in 1821. Soon scientists and tinkerers around the world, including visionaries such as Nikola Tesla, were experimenting with all manner of electric motors -- some worked with DC power, others with AC. By the end of the century, myriad electric motors had been produced, capable of exerting enough force with enough reliable control that they were practical for use in myriad applications.
Fast and fun on the trail, the SDURO HardNine handles rough terrain with ease, while its large tires roll over most obstacles without missing a beat. The pedal assist makes for quick, energy-saving climbing and the bike descends surprisingly well, too. Its front suspension provides a nice level of cushion on bumpy trails and while we missed having a full-suspension on this model, that would have added additional weight and costs.
Forward-thinking parents are giving up thier SUVs and opting for electric cargo bikes for getting the family around. Cargo bikes are seeing a resurgence in popularity with the rise of electric conversion systems that convert these awesome people movers into family toting electric vehicles. One year ago the Wall Street Journal ran a full page article in their weekend edition entitled The New Station Wagon. Since then the trend for...
The motor on the Patriot DreamE drives the chain and utilizes the gearing of the bike for remarkable power and speed. If you want more speed or hill climbing power, simply change the rear cassette. The motor is lightweight and mounted low on the frame for better balance. Unlike hub motors, this frame mounted motor allows you to remove wheels (e.g. to fix a flat) like a traditional bicycle - without any wires to disconnect and reconnect.

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.
EcoBike offers three e-bike models. The Vatavio fold-and-carry electric bike (pictured above) is innovative and well constructed. The Elegance (pictured below) is a classic design with step-through frame, offering an easy, comfortable ride. The AdventureÂ’s revolutionary frame design allows for true versatility, going from the pavement to mountain trails with ease.
The G-10 features a top-tube mounted on-off button and ‘set’ button for one of four power modes, all linked to a Groove Go wheel mounted motor via a removable clip-lock battery stashed under the down-tube. Kalkhoff has paired this with a mid-range Shimano Tiagra 1x10 speed drive-train and effective Shimano M396 hydraulic disc brakes. A nice touch is the anti-slip ‘grip-tape’-covered flat pedals, perfect for a bike to be ridden around town without specialist shoes.
This dexterous electric dirt bike is recommended for anyone over the age of 14. It’s fitted with double suspension and big tyres to help you tackle tough terrain. You also get a good selection of gears, that gives you optimal control. The Razor can go as fast as 15 mph on average, and comes with an excellent braking system. The aesthetics are on point, and the racer look is sure to impress. Don’t forget your helmet!

“I can go on Alibaba, buy parts, set up shipments, and get people to buy these things,” she says. “The question comes on the support side. Will they have spare parts? Will they have tech support? Do they carry insurance? Real manufacturers of e-bikes have serious insurance in case something goes haywire or someone has an accident. That’s $20,000 to $30,000 a year.”
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]
Designed for riding around town, this pedal-assist bike has four levels of electric assistance – Eco, Tour, Sport and Turbo – and a maximum assisted speed of 20 miles per hour. This is a well designed and engineered bike, with Shimano Nexus components and a Bosch Performance electric-assist mid-drive system. Front and rear lights are included, and you can even use the battery to charge your smartphone. The integrated ring-lock will help deter would-be thieves, but it’s always best to back this up with a dedicated bike lock.
Gearing: none (many hub motors, one motor revolution = one wheel revolution), fixed gear reduction for more torque, varies when geared motor drives the chain through the bicycle gears which increases torque about 50% (in low gear) for better hill-climbing and offers better top-end speed (in high gear) than direct drive systems using motors of similar wattage.
TerraTrikes make great electric recumbent trikes. Here are a few how to tips for converting the Rover and Rambler models, specifically with internally geared hubs. The TerraTrike Rover and the rambler models both are offered with internally geared hubs. It is possible to convert the trike to external gearing, but you will probably want the help of a bike shop that is familiar with recumbents. For a good bike shop,...

Electric bikes are here in a big way. Liberated from some of the normal constraints of standard bike design like weight and gearing, e-bike design has exploded; if you can imagine it, someone has built it. From cargo bikes to city bikes, messenger bikes to mountain bikes, road bikes, and even beach cruisers, there is something for everyone. The beauty of e-bikes is they make the joy of cycling accessible to so many people in so many ways.
