Proper Use

&

Always ensure before riding that all components are attached
properly, as neglecting to ensure this may cause issues in the future.
Always abide by the local laws of the areas that you ride in.
Here at FLX we’re always concerned with your safety, comfort,
and happiness. We can’t stress enough the use of proper safety
equipment in addition to the correct use of any FLX product. While the
use of pads and a helmet may not be required by law they will provide
an extra layer of protection, and we highly recommend their use.
Always wear appropriately bright clothing during the day and use
head- and tail- lights at night to increase visibility. Learn and use proper
cycling hand signals and always use caution when riding on the road
whether or not there is a bike lane.
FLX products were built for high intensity and heavy use, they
can stand up to quite a bit of punishment. Please take care of them as
rust, dents and other damage can affect the performance. For cleaning
information see Cleaning and Care.
Most adjustments to any FLX product can be performed with a
basic set of hex wrenches and other basic tool. Larger issues should be
handled by a qualified mechanic.

Instructions

To start the computer press and hold the “MODE” button for 1.5
seconds. Once this is done the “Power Level” section of the screen will
display the current level of pedal assist active. Default is 0, and
maximum is 5. The level of pedal assist can be adjusted by pressing the
“UP” or “DOWN” buttons as appropriate. When active the throttle will
also be active, and this can be triggered regardless of the level of pedal
assist by depressing the throttle lever found on the right-hand grip of
the handlebars.
Additionally a walk-assist mode can be activated by pressing
“DOWN” for 2.5 seconds. This is a single-speed designed to be an
average walking pace, NOT FOR RIDING.
When full, the “Battery Indicator” will show 5 segments, when the
battery is low there will be one segment, and to indicate that it needs
to be charged the segment will flash at 1Hz.

The headlight, taillight and backlight on the LCD screen can be
activated by pressing the “UP” and “MODE” buttons for 3 seconds,

similarly it can be turned off by holding the “UP” and “MODE” buttons

Battery Care

17

Removing the battery from the bike when storing it for a long
period of time is recommended. In this case store it in a cool, dry area
away from water. The charge left in the battery should be 50%-75% for
long storage times.
Cleaning the battery and battery housing should only be done
while disconnected and powered off. Use a dry rag, and if need be a
lightly damp rag. DO NOT spray with high-pressured water to prevent
damage or possible short-circuiting.
Only charge the battery with the supplied charger as others may
not function properly, and this increases the possibility of fire or
explosion. Charging the battery during the day in a dry space with a
smoke/fire alarm is recommended, while placing the battery on a
non-flammable surface. Do not store the charger or battery in a wet
place or in direct sunlight. Lithium-ion batteries are meant to be
recharged with 10%-15% of the charge remaining to prevent damage to
the cells. Keep both the battery and charger out of the reach of children

If there appears to be an issue with the charger or battery, stop use

immediatley and contact either the manufacturer or us at hello@flx.bike.

Cleaning & Care

Whenever you service, be sure to first remove the battery.

Keeping the chain, shifter, and gear cassette properly
lubricated will help prolong the life of your bike. The greatest enemy of
any bike is rust, so make sure to dry it off after a wet ride and store it in
a dry place. In general, wiping down your bike after a rough ride with

some soap and water should be plenty to keep it looking great, just
make sure to take special care around the electronics.

Useful Tips

19

Do not turn on the bike when the brake levers are depressed as this
will trigger the faulty brake sensor and disable the motor.
Inspect the bolts on a regular basis, to ensure that they are tight
and all components are secure. This is especially important if you are
riding in demanding conditions. As with all bikes pay particular attention
to the crank bolts, as they are subject to more loosening forces than any
other bolt.
Regularly check the brake pads, the provided Tektro pads should
be replaced if they have:
Been contaminated
Less than .8mm of material
Cracks or deformation
To replace the brake pads or perform other maintenance take it to
a qualified professional at your local bike shop.
The bike has a powerful mid-motor which places more stress on
the gears than a regular bike. Reducing the force placed on the pedals
whilst shifting will prolong the life of the drivetrain.
Properly inflate your tires according to riding conditions.
Under-inflated tires are prone to pinch flats, especially if riding off-road

Legal Requirements

The regulations for electric bicycles are constantly

being revised
and may change at any time. Obtain information regarding the current
legal requirements at both a general and local levelto ensure compliance.

For FLX e-bikes, special legal provisions apply for their limit of
use. As an e-bike they can be used both as a purely mechanical bicycle
or as a motor assisted means of transportation, in essence they can
operate as a bicycle at times and not at other times. Before riding on
public roads or trails with a FLX e-bike the user must inform themselves
properly on legal requirements enforced in the user’s country,
state/territory, and city. This information can be acquired by visiting
local e-bike retailers, and bicycle or e-bike associations.
The currently valid, national and local regulations also pertain to
age restrictions and specify the minimum age a user must be to drive
on which part of the road and whether certain driving permits are
required. The regulations for children riding on public roads are also
found here. It will be made clear if a helmet is required by law, what if
any head- or tail- lights are required.
