CHAIN
Lubrication
The chain should be lubricated at regular
intervals with a suitable chain oil. Never let the
chain dry out. A dry chain wears more quickly,
becomes stiff and can start to rust. Replace a
damaged chain.
1. Clean any dirt off the chain.
2. Lubricate the chain.
3. Pedal a few turns so that the oil comes in
the links.
4. Wipe the chain with a cloth or sponge.
Tension
A chain that is not properly tensioned can
be dangerous. It should not be possible to
move the chain more than 1 cm “up or down”
at the mid point, but neither should it be
overtensioned.
1. Undo the nuts on the back wheel and pull
the back wheel backwards to stretch the
chain.
2. Tighten the nuts. Make sure the wheel is
fitted straight.
3. Check that the wheel is firmly in place.
HUB BEARINGS
Check for play in the hub bearings by holding
the rim of the wheel on the bike and moving it
from side to side. Adjust any play immediately,
otherwise there is a risk of damaging the hub
bearings and the wheel.
FRONT BRAKE
The wire tension for the front brake is adjusted
with the adjuster screw on the brake handle.
FIG. 12
GEARS
The gear wire tension is adjusted with the
adjuster screw on the hub of the back wheel.
FIG. 13
SPOKES
Spoke tension
The spokes should be equally tensioned round
the wheel.
1. Check the spoke tension by squeezing two
adjacent spokes together.
2. Go round the wheel to check if any spokes
are loose.
3. Check that the rim is not warped by
turning the wheel and using the brake
pad as a reference point.
Broken spoke
Note that a warped rim or broken spoke
indicates that the wheel is damaged. Take the
bike/wheel to a workshop to be repaired.
LUBRICATION
Lubricate regularly as instructed below to keep
the electric bike in good working condition.
Make sure not to use too much lubricant,
otherwise there is a risk of it accumulating on
the brakes and reducing the braking power.
The speed control, brake pads and rims should
be kept free of grease and other lubricants.
• Lubricate the chain and derailleur with
transmission lubricant at 1 to 2 month
intervals, or more often if necessary.
• Grease the saddle post and lubricate the
eccentric brake screw, the front hub and
pedals with grease at 1 to 2 month
intervals, or more often if necessary, to
avoid unnecessary friction and to prevent
the saddle post fastening.
