The Finnish Revonte One is a lightweight powerful middrive ebike unit with built in CVT transmission that can operate in either automatic or manual shifting mode, It looks like pretty cool technology that won't be in North America for a while.
The Revonte One is a drive unit and gearbox combined, removing the need for a traditional gearing system in the rear wheel.
More radical designs of the mid-drive are certainly on the horizon though, in particular in the form of Finland’s Revonte ONE system. It is essentially a drive unit and gearbox combined, removing the need for a traditional gearing system in the rear wheel. The gears can be automatically changed with the continuously variable transmission, or CVT. design.
What are the potential advantages? It’s no exaggeration to say it could revolutionize many aspects of the e-bike. The most obvious one is that it removes gearing from the rear wheel which would bring the advantages of a totally maintenance-free e-bike. It also puts more weight low down and centrally so that handling characteristics would improve.
The drive unit quoted stats are a weight of 4.7kg, 250W continuous power rating with a maximum 1,500W and 90Nm torque. There’s a 416% gear range at 60rpm. The battery comes in at 3.98kg and has been developed to work with the system by partner company BMZ. Concept bikes have already been produced by Tunturin and Lavelle.
