Routine Maintenance
Daily use:
Keep the spinning bike on a dry, ventilated and flat floor. If not used in a long time, the bike
should be covered to keep its body clean and tidy.
Frame maintenance:
Wipe off sweat on the frame with cloth after exercise. Do not wipe the bike with wet cloth, in
order to avoid rusting.
Belt maintenance:
Check the belt pulley for cracking and deviation, and adjust or replace the belt in time.
Regularly clean the belt groove to prevent the belt from jumping out of the groove.
Inspection of body screws:
Always check the screws of all body parts for loosening or falling, and tighten or replace them
in time.
Inspection of resistance adjustment knob:
Always check the resistance adjustment knob for loosening or falling. Check whether the
resistance is reasonable, so as to calibrate resistance in time.
Inspection of pedals and cranks:
Always check the screws of pedals and cranks for loosening, and tighten them in time.
Saddle maintenance:
Always check whether the saddle is loose and tighten it in time. Wipe the saddle with cotton
cloth to keep it dry.
