Effigear and Valeo have made a motor gearbox combination that they display on their prototype emtb’s . Definitly interesting.
But for now I think my choice would be a kindernay Vii with a Gates Carbon belt on a Pole Voima super enduro emtb. The kindernay is not to far off the weight of a regular dereilure system and the Pole Voima doesn’t need to split the rear swing arm to get the belt on it.
I have also played with the idea of a “digital gear system”. Meaning you have a motor and dynamo setup. The cranks are connected to the dynamo motor and the drive motor goes to the reer wheel with a belt drive.
The dynamo motor provides resistance, speed controll and generates energy to top up on what the battery gives to the motor. If it was perfectly dialed in it feel just as a regular emtb,or even better. All digitial / simulated.
I’m no engineer though. And there is probably alot of issues with it.
It for sure would mean less range? It would probably need a stronger motor? Regulation issues? And your fucked if you run out of battery. But who wants to ride a heavy ebike with a flat battery anyway? (Just don’t run out of battery. And 1000wh?)
