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 fl ywheel to access the bolt 
on the handle side of the battery cap.

2. Using a 2.5mm Allen wrench, re-
move 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 at-
tention 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 instructions (avail-
able 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 approximately one half 
turn. Replace the old battery with the 
new battery. 

5.  Secure the cadence sensor to the main 
frame using the previously removed bolt 
and 4mm Allen wrench. Be sure to hold the 
cadence sensor arm while attaching bolt.
