TROUBLESHOOTING
A loud squealing sound from the brake pads – Using a 4-mm Allen Wrench, take off the bolt and spring
then slide pads out of the assembly. There is no need to remove the shroud from the Evolution model in
order to remove the pads. If the pads look glossy or shiny, you will need to rough up the surface with a wire
brush. After doing so, the pads need to be saturated with SCHWINN® Fit-Tech Silicone (#72016). Tighten the
bolt and spring to the pads only finger-tight. This will create longer life for the brake pads on your bike.
Tight resistance assembly – (The brake pads touching the flywheel with the resistance knob turned all the
way to the left). Turn the resistance knob all the way to the right and let sit over night. This will relax the
guide rod springs allowing space between the pads and the flywheel.
Brake pads off-center - Use a 10-mm wrench to loosen the nylon nut (# 95456) on the front of the bike.
This will allow you adjust the brake assembly until the brakes are evenly spaced from the flywheel. Retighten
the nylon nut using moderate torque.
Play in the Chain - (chain is too loose). Use a 14-mm wrench or socket to loosen each axle nut of the
flywheel. Use a 10-mm wrench and turn each chain tensioner bolt ¼ turn to the right. Get on the bike and
check for any play in the chain by rocking back and forth on the pedals. Once the pedals and the flywheel are
moving as one, tighten the axle nuts on the flywheel. Make sure the flywheel remains in alignment with the
frame.
Grind in the Chain – (chain is too tight or flywheel is out of alignment with frame). Loosen each axle nut
using a 14-mm wrench. Adjust the 10-mm chain tensioner bolts to align the flywheel with the frame. Make
sure that the chain tension is adjusted properly without being too tight. Adjust the chain tension by locating
the point where the chain is tightest during one revolution of the crank. Check the tension; you should be
able to move the chain up/down a total of 3/8” (in either direction). Ensure that the chain is properly
lubricated, then test-ride the bike.
Bike wobbling or uneven while riding – Check the foot levelers on the bottom of the stabilizers. Adjust
until the bike is square on the floor. Securing the leveler nut will prevent leveler from loosening.
Tight fit on the handlebar or seat post – Ensure that the handlebar/seat post extension tube and frame
sleeves are both clean and lubricated with SCHWINN® Fit-Tech Lube. If fit remains tight, try switching the
handlebar or seat post with one from another bike. If this does not fix the problem order new sleeve
(#84966 for IC bikes, #8001 for Evolution bikes.)
