3.2: SEAT CLAMP ADJUSTMENT & SERVICE
CAUTION! Avoid over-tightening the seat clamp.
In particular “dropper” seat-posts may not work correctly if the seat clamp is over tightened.
CAUTION! When adjusting the saddle height you MUST obey the Minimum insertion depth requirement marked on the Seat
Post. Also consult the relevant seat-pin manufacturers instructions in conjunction with these notes.
IMPORTANT SAFETY Always stop riding when making adjustments of any kind to the bicycle!
3.3: SET UP OF FORK
Tools Required: Good Quality Shock Pump for Air Spring Suspension Fork
Small Ruler
IMPORTANT SAFETY NOTE: Always stop riding when making adjustments of any kind to the bicycle!
The front suspension fork fitted to your Whyte bike will be pre-set with the standard settings. Before riding, you may need to
adjust these setting. First is the Sag setting on the fork. This is to ensure the forks are set-up correctly for your own body
weight, so the fork will perform as intended.
To set Sag on the front fork, you need to measure the amount the fork compresses when you sit on the bike in the normal riding
position. See the table on the right for our recommendation of front fork sag on your Whyte bike. To achieve this you will need to
adjust the air spring pressure inside the fork.
Refer to the specification tables in this manual, and then to the relevant fork manufacturers set up instructions to find how to
adjust the air spring pressure in the fork. Using a shock pump, either add or remove air until Sag is correctly set.
Please note that for the detailed instructions for servicing and all matters relating to the forks fitted to your Whyte bike, please
refer to the manufacturers instructions.
Rebound Damping adjustment:
This adjustment fine-tunes the speed at which the wheel returns to its normal ride height after hitting a bump. Refer to the rele-
vant manufacturers instructions to find out how to adjust the rebound damping. To demonstrate the effect of this function, turn
the adjuster to its slowest setting. Press down on the handlebars to compress the forks, then release the load. The suspension
recovers very slowly to its original position.
Repeat the above with the adjuster turned to the fastest setting and the difference will be seen immediately the load is released.
We recommend the optimum setting is to adjust the re-bound damping to be as slow as possible, but not so slow that the
normal ride height is not recovered. On very rough terrain, if the bike becomes progressively lower as more bumps are hit then
the re-bound damping is set too slow. On the other hand if the bike feels choppy and not plush then the re-bound damping is too
fast. A bit of trial and error is needed to get the exact setting.

4.0: SAFETY
IMPORTANT: The following are intended to be advisory notes on the safe use of your Whyte bike. You should also read thor-
oughly the General Instruction Manual also supplied with your new bike. If at any stage you are uncertain about the safety or
safe operation of the bike as a whole, or any specific component, then DO NOT RIDE YOUR WHYTE and instead please con-
sult the specific component manufacturers instruction manual or your Whyte Dealer for advice.
Maximum Weight Limit for Whyte e-Bikes: 19.5st. / 125kg (including the rider and the rider’s equipment)
WARNING: As is the case with all mechanical components, the bicycle is subjected to wear and high stresses. Different
materials and components may react to wear and stress fatigue in different ways. If the design life of a component has
been exceeded, it may fail suddenly causing possible injury to the rider. Any form of crack, scratches and decolouring in
highly stresses areas are showing that the component has exhausted its life time and has to be replaced. If you are in
any doubt about one or more components on your Whyte DO NOT RIDE YOUR BIKE. Consult the specific component
manufacturers literature, or take your bike to your local Whyte Dealer.

bicycle.
For the range of bicycles contained in this Supplementary Service Manual, there is also the following specific guidance:
5.1: GENERAL WHYTE LUBRICATION
For the correct lubrication regime and maintenance of all parts on a Whyte bicycle, please refer to the specific component man-
ufacturers detailed instructions bundled with this manual or for further information visit the specific manufacturers website.

6.0 Servicing the Whyte Modular Dropout Systems:
6.1: USING THE 12mm WHYTE QR SHAFT.
Referencing Figure 19 and 20. The rear wheel is attached to the frame by a lever-actuated mechanism that allows you to install
and remove the wheel without tools.
To undo and remove the axle from the bicycle, turn the lever anti-clockwise until the axle is disengaged from the threads in the
RH dropout, then pull the axle out of the hub and through the LH dropout to remove it from the frame. Note. If you have
placed the bike in a work-stand take care to support the rear wheel as you remove the axle, to prevent the rear wheel falling
out of the frame and potentially damaging any components in the process. If you are in the habit of turning your bicycle upside
-down to remove the wheels, please take care not to damage the saddle or any of the controls on the handlebars when doing
so.
To re-assemble the axle, ensure the wheel is placed correctly into the frame and the hub is aligned with the dropouts. Insert
the Axle into the LH dropout and push it through the dropout, hub and into the RH dropout. Turn the lever clockwise.
After inserting the axle through the dropout of the frame and wheel hub, it will be necessary to turn the lever several
times to fully engage the axle into the threads in the RH dropout before the axle tightens. The required minimum hand-
force is 15 Nm.
WARNING: If you are unsure about how tight the axle needs to be done up to, DO NOT ride your bike and instead
consult your Whyte Dealer who will be able to advise and demonstrate the correct closing force.
Ensure that the lever is back to its normal position after every adjustment is made. To do this, pull the spring-loaded ever arm
away from the bike (Fig. 19 Arrow No.1) until the lever arm dis-engages from the axle (Figure 20) Whilst the lever is dis-
engaged from the axle, rotate the lever (Fig.19 Arrow No.2) around to a ‘9’0’clock’ position as shown in Fig. 20. Next release
the spring-loaded Lever arm to re-engage the Lever Arm with the axle (Fig.19 Arrow No.3).
Under no circumstances should the 4mm Allen Screw in the centre of the Axle Lever arm be loosened. Do not loosen the screw
for opening or closing of the Axle System.
Always check for safety before riding
Before every ride check your thru axle System is in the Locked (CLOSED) position. Make sure that the wheels are cor-
rectly installed on the bicycle frame or fork, and the lever does not contact any part of the bicycle. If the lever contacts
anything, it might not be closed; replace the thru axle or consult your dealer for safety. Ensure that the tightening force
of the thru axle lever is minimum 15 Nm.
WARNING: A thru axle that is not correctly adjusted and closed to a minimum hand force of 15Nm, may allow the wheel to
work or become loose or become detached from the bike unexpectedly. This could cause the rider to lose control and fall and
may result in serious injury or death. Always make sure the thru axle is adjusted and closed correctly before every ride as part
of your Pre-ride checks.
