  In a Comment [Phys. Rev. Lett. 113, 029801 (2014)] on our Letter on
self-propelled asymmetric particles [Phys. Rev. Lett. 110, 198302 (2013);
arXiv:1302.5787], Felderhof claims that our theory based on Langevin equations
would be conceptually wrong. In this Reply we show that our theory is
appropriate, consistent, and physically justified.
