Unlike treadmills, the internal drive belts of bikes and ellipticals are sealed and do not require regular lubrication. However, if you hear a noise inside the casing after a year of use, simply book a "General Service" via the Decathlon App.
PRO-TIP FOR ELLIPTICALS:
Ensure you tighten the "pivot point" bolts every 6 months. This keeps your motion completely silent and smooth!
