While the first functional battery was developed in the year 1800 by Italian physicist Alessandro Volta, a practical battery would not be seen for several decades yet. By the end of the 19th century, practical and portable batteries were more widely available, this finally freeing the electric motor to be used in a wide new array of applications. It might come as a surprise, but the electric motor, battery, and a bicycle were first paired as far back as the 1890s. It would be approximately 100 years later that electric bicycle development finally entered the mainstream, but the technology and concept behind the electric bike were all in place generations ago.
Propel started in a small, second floor office with a motivating belief that electric bikes would change people’s lives, and they have. Since 2011, we have been closely listening to our customer’s needs, spent countless hours traveling and researching to learn more about ebike technology as it evolves, and we are advocating for changes in policy that promote a more equitable stake for electric bicycles in the world of transportation. Join us in this movement towards a more sustainable future; together, let’s change the way we move.
The F1-trained engineers at William Advanced Engineering assisted with the electrical parts and the result is a 250W motor that provides pedal assistance via the front hub – which is a highly unusual approach – drawing power from a 300Wh battery pack that sits in a bag and goes on the front where the Brompton luggage rack would normally sit. You can also opt for a larger bag that holds both the battery and your spare suit or laptop or whatever.
The Patriot DreamE results from the combination of the popular Day 6 bicycle with the Kinetic8-Fun mid-drive motor kit. The unique Day 6 styling eliminates leaning forward, so you sit perfectly upright. That means there is no more stress on wrists, neck, back, and crotch. It also means a superior breathing position and a better way to enjoy the scenery. The step-through design makes for easy mounts and dismounts, while the low seat allows the rider to reach the ground with both feet for stability and safety.
Cape Fear Community College students are utilizing the E-BikeKit™ electric bike kit in the designing and building of their own electric bicycles! ORIGINAL ARTICLE POSTED by the Port City Daily staff "CFCC student-built electric bikes to be in Azalea Fest parade Some innovative designs by Cape Fear Community College students will be featured in this year’s N.C. Azalea Festival. For the past year, students in CFCC’s mechanical engineering program have been hard...
But this bike isn’t just about the accessories. The powerful 48V 13Ah battery will allow you to pedal for longer, with some riders getting over 100 miles from one charge. The bike can be ridden as pedal-assist or throttle only and it’s equipped with full suspension and puncture-free Kenda tires. It folds up neatly to fit into the boot of a car or for commuting, though at 57 pounds, it’s heavy to cart around. A great value-for-money commuting bike with lots of features.
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…
Riese & Muller’s Nevo line definitely tops my list for commuting electric bikes. These bikes are premium, custom made bikes for a reasonable, middle-of-the-road price. All Riese & Muller bikes are hand made in Germany exactly to your specifications. The Nevo line specifically is incredibly well balanced and keeps riders in a comfortable, upright position. Riders also get a suspension seatpost (either the Cane Creek Thudbuster or Satori Elegance LT), which is a nice compromise between the full suspension Homage line and a complete hardtail.
Pedelecs are much like conventional bicycles in use and function — the electric motor only provides assistance, for example, when the rider is climbing or struggling against a headwind. Pedelecs are therefore especially useful for people in hilly areas where riding a bike would prove too strenuous for many to consider taking up cycling as a daily means of transport. They are also useful for riders who more generally need some assistance, e.g. for people with heart, leg muscle or knee joint issues.
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.
Tackle your daily commute with ease or go for a weekend cruise in style with the Gazelle CityZen T10 e-bike. And don’t worry about those thigh-burning hills; the Bosch motor offers four assist levels—Eco, Tour, Range Sport, Turbo—making hills a breeze and the Lithium-Ion battery provides a range of up to 85 miles in Eco mode. The bike is one of the first to use Bosch's new integrated battery, which is concealed in the downtube. The matte black paint and classic, step-through design give a classic look while fenders, pannier racks, and integrated lights add practical functionality. The bike is easy to maneuver in city streets, but still has assist up to 28mph so you can cover a lot of miles and power up steep hills. There's a suspension fork too. It's not at the level of something you'd find on a mountain bike (or even some better e-bikes) but it takes the edge of some potholes and curbs.
