Bike riding and SmartLipo. Will cycling reduce or increase the length of time for swelling to decrease?

Long distance cycling two weeks after lipo will cause you to swell. There's no way to tell how much swelling you will experience, but you will be uncomfortable perhaps for several days afterwards. If the bicycle seat makes contact with the treated areas, you will experience additional inflammation. I would recommend you support the charity event in some other way.

Thanks for sharing your question. I can
appreciate your concern.Biking will increase the fluid collection among the tissues making the improvement of the contour to be delayed. Wait until the tissues are more stable and the fluid management is more controlled. 

Finally, make sure that your doctor is
aware of your process. He should be able to guide you best in your care.

Wishing you the best in your journey

I allow my patients to be as active as they are comfortable being after this procedure. I don't think it's going to cause any harm or delay in the healing. It's a pretty big push that soon after the surgery So don't get hopelessly ego involved if you can't complete the entire ride.
