Our guide to help you understand gear ratios and what gears you might need when buying an ebike
In the late 19th century, derailleur gears were invented to enable the chain to shift from one cog to another, hence the term "derail." The purpose of gears stems from the understanding that efficient pedaling on a bicycle occurs when the rider maintains a cadence of around 80-90 revolutions per minute. This cadence feels natural and optimizes the use of muscle strength while meeting the cardiovascular demands of cycling. While pedaling at this speed is ideal on flat terrain, gradients introduce the necessity for gears. When an electric motor is added to the equation, it significantly increases the achievable speeds beyond what one would typically cycle at.
The gear ratios needed for an e-bike depend on various factors such as the type of motor, the terrain you plan to ride on, and your personal preferences. Here are some considerations to keep in mind when selecting gear ratios for your ebike:
It's important to note that electric bikes often have a higher average speed compared to regular bicycles due to the assistance provided by the electric motor. Therefore, it may be beneficial to have a wider gear range.
The Evari 856 model incorporates the Gates Carbon Belt drive system, which is utilized in both our single-speed and Rohloff electric bikes. This system offers several advantages over traditional chain drives. One notable benefit is that the drive belt does not require oil, resulting in a cleaner and maintenance-free experience.
For our single-speed setup, the high-torque (85Nm Bosch Performance Line) motors are well-suited. We have carefully selected a gear ratio that allows for comfortable cruising without exerting excessive energy to overcome inertia when starting from a stationary position. The single-speed configuration performs admirably on flat terrain and can handle mild gradients of approximately 3-4%.
The Rohloff E-14 system we offer provides comprehensive versatility via an electronic shifting system. With 14 gears available, gears 1 to 6 are not typically necessary for flat terrain. When you come to a stop, the Rohloff system defaults to the 7th gear, optimized for smooth starting on level ground. Moving through the gears is quick and seamless, and if you need to exceed the motor-assisted limit of 25 km/h, there are still ample gear options to propel you beyond 40 km/h. On the other end of the spectrum, the gear range allows for conquering steep inclines. The easiest gears enable climbing gradients exceeding 30% with minimal effort while in turbo mode.
In summary, the Evari 856 presents the choice between the simplicity and low maintenance of a single-speed setup, ideal for flat terrain, and the versatility of the Rohloff system, offering a wide gear range to handle various scenarios, including steep climbs and high-speed riding.
We are currently in the process of developing an 856 with a Classified gear system, a revolutionary advancement in gearing technology. This innovative system introduces two distinct gears: a launch gear and a cruise gear. The launch gear is specifically designed to accelerate swiftly from a stationary position and conquer hills with ease. On the other hand, the cruise gear is optimized for achieving optimal efficiency once you have reached your desired speed.
The Classified system utilizes an exceptionally lightweight internal hub gear mechanism. Shifting between gears is seamlessly executed by a convenient toggle control located on the handlebar, which is wirelessly connected via Bluetooth technology. The results from our ongoing testing phase have been highly promising, and we are excited to share further updates in the near future. Stay tuned for more news on this groundbreaking gear system.
Over run - Bosh ebike motors have the ability to carry on producing power for a short period of time when you stop pedaling. This is mostly useful for mountain biking to get over obstacles.
