Serial Number

Find the serial number on the underside of the machine base. Decode the information in the serial number with the below instructions:

XXXXXX - SKU

VVV - NLS Vendor Code

WKYY - Week/Year

9999 - Machine that made production run

Troubleshooting

Problem: Chain is too loose, tight, or making a grinding sound.

Solution:

Use a 15mm wrench or socket to loosen ﬂywheel nuts (A) and1.

tensioning screws so that when you grab a pedal and try and

move it back and forth, you can feel play in the chain.

Use a 3mm Hex wrench to gradually tighten the drive side ten-2.

Check for free play with the crank in the 12, 3, 6, and 9 o’clock3.

positions in case there is a loose or tight spot and make sure

there is no play.

Add an additional 1/2 turn on the drive side tensioning screw.4.

This should help keep the chain tensioned as it is new and

breaks in.

Tighten the non-drive side tensioning screw to align and center5.

the ﬂywheel in the brake assembly.

Tighten both ﬂywheel nuts.6.

NOTE: Make sure that the ﬂywheel aligns with the frame.

Troubleshooting

Problem: Smart Release engages/disengages when pedaling

Solution: Adjust Smart Release

Attention: Only a mechanic trained to work on Schwinn®IC

bicycles should do this procedure. Make adjustments

to the Smart Release™ mechanism only to restore

the mechanism to factory speciﬁcations. Never

overtighten.

1. Begin by riding the bike. This forces the the Smart Release™

mechanism to break free. Pedal up to a moderate speed with

little or no resistance on the ﬂywheel while applying enough

back pressure to the cranks to release the mechanism. Repeat

this several times to ensure that the mechanism is up to

operating temperature and to feel the initial setting.

2. From the front of the bike, insert the Smart Release™ adjusting

tool into the space between the chain guard and the ﬂywheel.

3. Rotate the ﬂywheel until the 7mm diameter hole in the Smart

Release™ adjusting plate is visible from the front of the bike.

4. Tighten the resistance mechanism to prevent the ﬂywheel

from rotating.

5. Place a 50 lb. dumbell or weight on the right side pedal (chain

guard side) with the crank in the 9 o’clock position.

Note: When properly adjusted, the Smart Release™

mechanism should break free allowing the crank arm

to rotate down under this amount of weight.

6. Insert the Smart Release™ Adjusting Tool so that the bend in

the tool corresponds to the shape of the ﬂywheel.

7. Insert the pin of the tool into the hole of the Smart Release™

adjusting plate.

8. Pull the handle of the tool UP toward the top of the ﬂywheel

to increase the release pressure (higher breakaway force)

and DOWN to decrease the release pressure (lower

breakaway force).

9. Ride the bike to test that the factory speciﬁed resistance has

been achieved.

Problem: Metal scraping sound from brake

Solution: Flywheel or Eddy brake misaligned

Follow previous procedure to tighten the chain.1.

Troubleshooting

Problem: Bike is Wobbling or Uneven While Riding

Solution:

Check the foot levelers on the bottom of the stabilizers.1.

Adjust the levelers and the bike until it is square on the ﬂoor.2.

Secure the leveler nuts to prevent them from loosening.3.

(See Figure 5.)

Problem: Crank Arms or Pedals Feel Loose

Solution:

Make sure the pedals are tightly screwed into the crank arms.1.

Make sure the crank bolts on both crank arms are tight.2.

Make sure the bottom bracket is tight in the frame and bearings3.

operate smoothly. Torque bottom bracket cups to 600-700 kgf*cm

/ 44-51 lbs*ft / 60-69Nm.

Tighten and torque the crank arm bolts to 550-600 kgf*cm /4.

40-44 lbs*ft / 55-60 Nm.
