Whether Brose, Bosch, or Bafang – modern mid-motor pedelec drives are all pretty similar. The start-up Revonte, on the other hand, wants to do a lot differently with its One Drive.
Last year, the Finnish start-up Revonte presented the new One Drive e-bike drive. The compact mid-engine offers an integrated transmission, which like an automatic CVT, can automatically switch to the appropriate gear while driving. This, in turn, makes it possible to dispense with hub or derailleur gears, which brings optical advantages in particular.
However, the company has no interest in making the bikes themselves. They want to simply become a drivetrain supplier. In this regard, it’s already signed up Tunturi and Lavelle Bikes, two bicycle brands that are expected to launch the first models with the innovative pedelec motor in 2021.
The Lavelle, it is a young British brand that builds very eye-catching e-bikes with a carbon frame and one-armed front fork. And in the case of Tunturi, it is a well-known traditional brand, especially in Scandinavia, which has meanwhile incorporated the Dutch Accell Group. It is still unknown which type of bike Tunturi will equip with the One drive.
Now that the first bikes and manufacturers have known where the system is installed, the makers have published a video that shows how their mid-engine works when driving. To do this, they present various situations that can be experienced on a journey and how the drive responds to them.
The Revonte One-drive, which weighs less than 5 kilograms, provides 250 watts of continuous and 1,500 watts of maximum power as well as 90 Nm (66 lb-ft) of torque. The driver either uses a continuously variable mode, in which the support force automatically adapts to the driving situation. Alternatively, it is possible to simulate gear shifts with five or ten gears.
In addition, the drive enables performance adjustment via a comprehensive mobile application, which allows the user to modify the drive character according to his own wishes. In addition, to configure your bike behavior, the app will also allow you to get theft alerts and track bike location, monitor the health of your bike, or view the stats of every ride you’ve ever done.
