The present invention relates to an electric drive system for a bike comprising a portable electric friction drive device (1) and a bike bracket (13) configured to be mounted on a bike. A first drivedevice attachment point (3') is located at a rear part of the friction drive device. A second drive device attachment point (4') is located between the front part of the friction drive device and therear part of the friction drive device so that the friction drive device is configured to rest against the second bracket attachment point (4). An inclination control arrangement (2) is configured tocontrol the inclination of the imaginary line between the second drive device attachment point and a contact point (9') of the drive wheel (9) by adjusting the tilt of the friction drive device over the second drive device attachment point. Further, the invention relates to a portable electric friction drive device. Yet further, the invention relates to bike (60, 70) having at least one wheel, comprising the electric drive system, wherein the drive wheel is arranged to be contactable to the tire of said wheel at said contact point.

    本发明涉及一种用于自行车的电动驱动系统,该电动驱动系统包括便携式电动摩擦驱动装置(1)和构造成安装在自行车上的自行车支架(13)。第一驱动装置附接点(3′)位于摩擦驱动装置的后部处。第二驱动装置附接点(4′)位于摩擦驱动装置的前部与摩擦驱动装置的后部之间,使得摩擦驱动装置构造成抵靠第二支架附接点(4)放置。倾斜控制装置(2)构造成通过调节摩擦驱动装置在第二驱动装置附接点上方的倾斜来控制第二驱动装置附接点与驱动轮(9)的接触点(9′)之间的假想线的倾斜。此外,本发明涉及一种便携式电动摩擦驱动装置。另外,本发明涉及一种具有至少一个车轮的自行车(60、70),该自行车包括该电动驱动系统,其中,驱动轮布置成能够在所述接触点处与所述车轮的轮胎接触。
