So you see this is for an diy electric bike. I want to use a 895 dc motor that runs at 12v 3000rpm 5kg/cm torque and at 24 6000rpm 10kg/cm torque . I can gear it down with a ratio of 8 to 1, so the rpm would become 375 at 12v and 750rpm at 24v. The bike will go at to maximum of 25km/h, after that the motors will stop working (because of the law). but even just 12v 375rpm is about twice as much as the rpm that the wheels will have at 25km/h. So i'm worried this will not be efficient/ effective at all? I mean will it even be able to exert some torque in this scenario?
