Calibration of Pendulum Scale
Frame Cover Screw
Balancing spring
(attach the weight here)
4KG Weight
(10 lbs = 4.5 KG)
1. Loosen the tension device so the brake
belt feels loose.
2. Make sure the “0” on the pendulum scale
lines up with the notch in the Pendulum.
(see previous page)
3. Detach the front screw in the frame
covers.
4. Fasten a 4KG weight at the balancing
spring. A 10 lb.weight plate is 4.5KG-
and this can be used if a 4KG weight is
not available.
NOTE
: The weight should not be less
than 3KG. Take the left cover a little to
the side so the weight cord hangs between
the covers.
5. When correctly set, the Pendulum Scale
should read the same as the weight.
If using a 10 lb. weight, the scale
should read 4.5 KP.
6. If the pendulum scale is not lining up with the
weight being hung (4.5KP), adjust the
pendulum weight so that the notch on the
pendulum lines up exactly with the scale
(4.5KP). To adjust the pendulum weight, use
the hex key provided with the bike. Loosen the
screw at the back of the pendulum and slide the
small adjustment weight up or down.
Pendulum Adjustment Weight
Loosen the hex screw on the back side
of the pendulum. Loosen the screw
and slide the adjustment weight up or
down then tighten the screw.
Check the calibration of the pendulum weight once a year or when needed.
