Recumbent Bike: Realigning the Seat
If the seat rocks side-to-side, you need to realign the center wheel
underneath the seat. Adjustment screws are located on the left
side of the seat rail.
To remove seat wobble (side-to-side movement), take the following
steps.
1.
Obtain a ³⁄₁₆-inch and ⁵⁄₁₆-inch hex key.
2.
Use the ³⁄₁₆-inch hex key to loosen the two adjustment screws
as shown in the following figure.
Figure 7: Loosening the two adjustment screws
3.
Use the ⁵⁄₁₆-inch hex key to turn the wheel lock adjustment key
clockwise ¼ turn as shown in the following figure. This process
realigns the center wheel inside the top rail. Leave the ⁵⁄₁₆-inch
hex key in place while you tighten the adjustment screws with
the ³⁄₁₆-inch hex key.

4.
Remove the hex keys and check that the seat no longer rocks
side-to-side. If the rocking movement continues, you need to
repeat steps 2 and 3.
