Setup and Assembly
The ONETWOFIT Mini Exercise Bike typically requires minimal assembly. Follow these steps for initial setup:
- Unpack: Carefully remove all components from the packaging. Ensure all parts are present according to the packing list (refer to product packaging for details).
- Attach Pedals: Identify the left (L) and right (R) pedals. Attach them securely to the crank arms. Note that the left pedal often screws counter-clockwise.
- Placement: Place the exercise bike on a flat, stable surface. For leg exercises, position it under a desk or in an open area. For arm exercises, place it on a sturdy table or desk.
- Secure with Strap (Optional): If the unit tends to slide during use, utilize the included strap to secure it to a table leg or chair leg. The anti-slip rubber pads on the base provide additional stability.
