Replace Hub Batteries (400 Pro/300 Pro only)
Over time, the batteries that power the electronics in the hub will need to be changed. See Preventative Maintenance for
when to replace. The CycleOps Pro Series indoor cycle uses two AA batteries. The battery cap is split to make this task as
easy as possible.
1. Rotate the flywheel to access the
bolt on the handle side of the battery
cap.
2. Using a 2.5mm Allen wrench,
remove the bolt on the battery cap.
Pull the plastic battery cap away
from the hub using the molded
handle.
3. Replace the batteries, paying close
attention to properly line up the +/-
poles, then replace the battery cap
and tighten the bolt.
6. Using a 4mm Allen wrench and three
chain guard bolts, reattach the chain
guard.
NOTE: After replacing the battery, Joule must relearn the coded ID for the sensor. Reference Joule user guide for instruc
-
tions (available at www.cycleops.com).
4. Using the new battery (compatible
CR2032), remove the battery cover
on the back of the cadence sensor by
turning counterclockwise approximate-
ly one half turn. Replace the old battery
with the new battery.
5. Secure the cadence sensor to the
main frame using the previously re
-
moved bolt and 4mm Allen wrench. Be
sure to hold the cadence sensor arm
while attaching bolt.
