An electric wheelchair with quick-release drive wheels includes: a chassis, and two guide wheels and two said drive wheels. The drive wheels are rotated by a drive mechanism and connected to the drive mechanism by a quick-release mechanism. To detach the drive wheel, the user can press the cover to make the rolling balls move out of the receiving groove and back to the arc-shaped engaging portion, which allows the hollow shaft to disengage from the drive shaft. Then, keeping pressing the cover can detach the drive wheel from the drive mechanism. To assemble the drive wheel, the user can press the hollow shaft into the axial hole to make the rolling balls engage in the receiving groove, so that the drive wheel is assembled to the drive mechanism. The assembly and disassembly of the drive wheel require no wrenches or other tools, and therefore are very convenient.
