Note: Maximum travel distance on a fully charged battery is measured at a condition
of 20°C, no wind, flat road, total bike weight 75Kg, and 25km/h speed. This will vary
according to load, road conditions, wind direction, temperature, braking and restarts,
tyre pressure and prompt battery charging. To obtain the maximum travel distance, we
suggest you check all factors within your control, including overloading, driving style,
tyre pressure and timely battery charging.

3. Assembly & Adjustments
3.1 Assembling And Adjusting The Handlebar
• Place the handlebar onto the handlebar stem, place on the cover, and fix with the
four screws provided. The tighten torque should not be less than 18 Nm.

Hexagon socket screws

• To align the handlebars, face your bike and hold the front wheel between your
legs. Turn the handlebars so that they are perpendicular to the front wheel.
• Tighten the screw that fixes the handlebar attachment to the frame. The
tightening torque should be no less than 18 Nm.

3.2 Adjusting The Saddle
• The saddle post must be inserted to at least the circular safety mark
engraved on the tube (shown below).
• An ideal saddle height is when the knee is at a soft bend when you are
sat on the saddle with your foot on the pedal at it’s lowest point. Adjust
the saddle to this height.
• The saddle should be parallel to the ground for maximum comfort
• The tightening torque for the saddle mounting screw and saddle post
mounting screw should not be less than 18 Nm.

3.3 Adjusting The Wheels
• Tighten the screws to make sure the front and back wheels are fixed to
the front fork and frame.
• Recommended tightening torques are as follows:
Front wheel hub: 18 Nm
Rear wheel hub: 30 Nm

9fb.com/westhillbikes • westhillbikes.com
3.4 Adjusting And Maintaining The Brakes
• Make sure the rotors are true. Spin the wheel and, sighting against
the pads, watch for wobbles. If the rotor clears the pads and calliper,
the bend probably isn’t worth straightening. If you spot a warp, try to
straighten it by clamping a clean adjustable wrench along the rotor and
bending toward true. Make sure everything that touches the rotor is
clean. You don’t want any grease there to reduce the grip.
• If your brakes squeal, something is probably loose. Check all bolts
holding the rotor on, as well as the calliper bolts and adapter bolts (if
your bike is fitted with one).
• If everything’s snug, the rotor and pads should be cleaned.
• If one lever pulls back farther than the other, try to equal out the travel
by dialing the lever limit screws in or out. If that doesn’t work, it’s time
for a shop to bleed your hydraulic fluid.
• Inspect hydraulic system for leaks. Check the levers, callipers and all
along the housing. Take a leaky system to a professional or contact us.

3.5.2 Adjusting The Rear Derailleur
• Adjust the lower bolt to make the guide wheel move to the free-wheel; align the
centre of the guide wheel and the outer line of the smallest sprocket.
• Turning the front chain-wheel, operate the gear lever to shift to the lowest gear,
then tighten the derailleur cable and fix it by the derailleur cable nut.
• Turn the low adjustment screw so that the guide pulley moves to a position
directly below the largest sprocket.
• Tighten the adjust nut when the real gear is lower than the gear shift shows;
loosen the adjust nut when the rear gear is upper than the gear shift shows. It is
OK when the gear changes correctly and smoothly.
