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. Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes, have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging. 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. 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 created 18650 battery packs are commonly used among Do-it-yourself ebike makers.
The final thing I love about this the Riese & Müller Delite GT Touring is the plus size tires. If you’ve ever been on a bike for the majority of the day, you know that any little bit of cushioning can make all the difference. Riese & Müller have provided this extra cushion in their tires. These tires are also excellent for wet weather and some light off-roading if you want to take a shortcut.
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.
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...
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…
For many bikes, battery range is more important that total power (because they're all pretty powerful). You want a bike that delivers a range long enough for your rides at the power levels you want. Most e-bikes will have three to five levels of assist kicking in anywhere from 25 percent of you pedal power to 200 percent boost. Consider how fast the battery takes to recharge, especially if you'll be using your bike for long commutes.
