Measuring Sag
The recommended sag of the front fork is 20mm into the travel, which can be measured with
the o-ring found on the lower portion of the right stanchion. To measure sag, place your bike
somewhere level where you can safely put your full weight on the bike while balanced. It is
recommended to have a friend help balance the bike during this portion of adjustment.
• Slide the o-ring all the way up to the bottom of the air chamber.
Then seat yourself on the bike, engage the brakes, and move into an
aggressive standing position with your feet on the pedals.
• Dismount from the bike and measure the amount of travel between
the o-ring and the air chamber. If the measurement is more or less
than 20mm, start with adjusting the air compression appropriately
and then fine-tune by adjusting the preload.
Adjusting Air Compression
Adjustment of air compression will require a shock pump. Use Figure 1 “suggested starting air
pressure” on pg. 20 to find your recommended air pressure.
• Remove the valve cap on the bottom right side of the front fork and
connect your shock pump to the pressure valve.
• Review the current air pressure and adjust according to Figure 1.
finetune the pressure with the shock pump to your desired comfort.
• Be sure you remove the shock pump in between adjustments as
leaving it on can affect the active pressure in the suspension. After
completing adjustment, reinstall the pressure valve cap.
The R-series defaults to a baseline setting. Follow the guides below to adjust the suspension
to your desired comfort level. The RX is equipped with an inverted coil-spring fork with air
assist and the ability to adjust preload and rebound damping. The rear suspension is a coilover
piggyback mono shock with the ability to adjust preload, compression, and rebound damping.
The R is equipped with a standard front coil suspension fork and only allows adjustment to the
rear suspension.
Adjusting Preload
Preload is adjusted with the dial on the top left stanchion.
• Turning the preload dial clockwise (+) will increase pressure on the
spring coil.
• Turning the dial counterclockwise (-) will decrease pressure on the
spring coil.
Suspension Adjustment Guide
Front Suspension Adjustments
If any of the instructions are beyond your skill set, we recommend taking your Super73
to a certified E-Bike specialist or professional cycle mechanic for adjustments.
!
Changing suspension adjustment can change the handling and braking characteristics of
your Super73. Never change suspension adjustment unless you are thoroughly familiar
with the suspension system instructions and recommendations, and always check for
changes in the handling and braking characteristics of the Super73 after a suspension
adjustment by taking a careful test ride in a hazard-free area.
