Bridge the gap between science and nature with F1s, the next generation pleasure product for men that makes you the master of your destiny. And with a window in the casing, you can add a never-seen-before element and see your pleasure in action.

Using powerfully intense dual motors, Cruise Control™ and LELO’s revolutionary SenSonic™ technology, F1s massages you with deeply satisfying sonic waves for an entirely new, completely mind-blowing sexual experience. Or better yet, utilize the free SDK to create your very own sensations and track your progress - and prowess - through the customizable internal sensors!


Download the exclusive LELO app, compatible with iOS and Android. Connected by Bluetooth, the app allows you greater and closer control over your personal pleasure. With the app, you truly put pleasure at your fingertips!


Free SDK for iOS and Android platforms is now available for download.



Through its unique dual-motor design, the F1s Red combines conventional vibrations with an entirely new sensation never before experienced in a male pleasure product: SenSonic™ technology.


It’s the same high-tech concept that made the LELO SONA™ the world’s bestselling sex toy of all time. Instead of standard vibrations, one of the motors emits powerful sonic waves that permeate deep into your penis, making it feel as though it’s resonating pleasurably from all directions all at once, instead of simply tickling the nerve endings on the surface of your skin. It will help you achieve the most overwhelming orgasms of your life. 


Combined with the patented Cruise Control setting, which ensures F1s never experiences a frustrating power drop during vigorous use. Instead, it intelligently monitors and controls the intensity to ensure you get a completely seamless, uninterrupted experience.
