We're gald to announce that we finally released the new 1500W BEST system. The new motor has been possible thanks to the manual winding which offer enhanced performance. With a top speed of 60km/h on a standard 27.5" mountain bike, a torque of 150Nm, and a maximum power of 2200W ( with the 48V battery) the BEST 1500 sets new standards for high performance ebikes. It's possible to buy just the motor and controller, and combine them with a custom battery up to 72V for a maximum power of over 2800W. In addition to that, the system has the full connectivity with the Smartbox module: by your smartphone you can change the motor settings to match your daily needs. Beyond the Limits.

Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.
DRIVE MOTOR The EcoBike is powered by an innovative hub-mounted, brushless permanent magnet motor with a triple planetary gear drive system and proprietary heat resistant materials. The propulsion system delivers the highest torque and is the quietest in its class. The drive motor is nominally rated for continuous output at 360 watts (Elegance & Adventure) and 290 watts (Vatavio).
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.
E-bikes are one of the latest ways technology is infiltrating the fitness market. Although they may seem techy and confusing at first, they really are just regular bicycles with a little extra boost. To test one, ask your local bike shop to demo a model they have available (pro tip: If a bike shop won't let you demo, don't shop there). Just getting on one will definitely help you understand how an e-bike works and how one might work for your lifestyle and goals.
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. 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.
In a single screen, with simple controls, the BionX command console displays important travel information and allows the rider to easily switch between different power modes. In assistance mode, the display indicates the power supplied by the battery. In generative mode, the display indicates the energy transmitted to the battery. The console is a multifunctional odometer and displays:
Irvine, Calif. – As eBikes transform into a "lifestyle product," smart aesthetics and attractive design play an increasingly important role. That’s why Bosch eBike Systems is setting the pace: for Model Year 2018, presenting the PowerTube 500, a battery which can be integrated into the frame of the bicycle. The PowerTube 500 combines modern design with first class Bosch technology for eBikers who prefer a clean and timeless look.
In a parallel hybrid motorized bicycle, such as the aforementioned 1897 invention by Hosea W. Libbey, human and motor inputs are mechanically coupled either in the bottom bracket, the rear wheel, or the front wheel, whereas in a (mechanical) series hybrid cycle, the human and motor inputs are coupled through differential gearing. In an (electronic) series hybrid cycle, human power is converted into electricity and is fed directly into the motor and mostly additional electricity is supplied from a battery.
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.
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.
Motor: We have a blog post showing some motor differences: https://www.ebikekit.com/blogs/news/its-whats-inside-your-motor-that-counts Cabling is probably the #1 issue when something goes wrong. Good connectors, good cables, and good assembly (bike shop!) are crucial Strain reliefs on all cable joints! Where you have a junction box or a connector, the stress is concentrated over a small area near this stiff spot on the cable. This can cause small breaks on the internal...
