This notice has been supplied to you with your LT by your Retailer or your DOUZE Cycles Technical Centre. Every bike is assembled,
configured and checked by a qualified person who has received the relevant training and materials.
Before taking the road, please read the safety advices and instructions to get the most out of your LT:
• Before use, always check the main steering and safety elements: tightening of the handlebars, stem and wheels, tyre pressure and correctly
functioning brakes
• Always wear suitable equipment. In France, helmets are mandatory for children under 12 and are highly recommended for everyone.The wearing
of an approved high-vis vest is mandatory for all cyclists and any passengers when cycling outside built-up areas, at night or when visibility is poor.
•Always observe the Traffic Laws of the country in which you are cycling. Legislation on mandatory equipment and the Traffic Laws differ from
one country to another, so please find out before you travel.
• Ensure that you are visible and able to alert other users to your presence. In France, reflectors, headlamps and a sound warning system audible
at up to 50 m are mandatory.
• The load on your LT must be stable and not pose a danger to any passengers or other road users. Make sure that the load does not exceed the
width of the handlebars.

FIRST USE
Every DOUZE cyclist has their own unique height, body shape and ri-
ding position. Your cargo bike has been designed to be used in daily
life, for business and pleasure. It is, therefore, essential to adjust your
LT to your body shape for optimal comfort and safety. Your Retailer or
DOUZE Cycles Technical Centre will help you make such adjustments
when you receive your cargo bike. They can be tuned during the first
mandatory servicing.

FIRST USE
Adjusting the saddle height
The ideal height is when your knee is slightly bent when the pedal is in
its lowest position. To adjust the saddle height, open the saddle clamp
lever, then close it ensuring that the seat post is fully locked in place.
For your safety, do not exceed the insertion limit
of the seatpost as indicated by the marking “MIN
Insert”. (Fig-1)
Adjusting the saddle
The saddle clamp lets you adjust the angle and height of the saddle to
suit your body shape and riding style (Fig-2). A neutral configuration is
obtained with the saddle horizontal and the clamp in the centre.
We recommend that you lower the saddle if you are very tall or raise it
if you are of below-average height.
Adjusting the brake levers
Your fingers should sit naturally on the brake levers.
To reduce braking time, position the levers in line with your forearms.

On the other hand, if you intend to store the batte-
ry for a long period without using it (two weeks or
more), do not charge above 70% of the total capacity.
A completely discharged battery must not be stored
in an environment that is too cold (<10°C) or stored
for more than 24 hours without being recharged,
otherwise, it enters into a state of deep discharge,
which may damage it permanently.
Charging and fitting the battery
To optimise your battery’s performance, it is important to fully charge
and discharge the battery for the first three uses. After these first three
cycles, it is no longer necessary to discharge the battery completely
before recharging.

or any other type of non-asphalt road suitable for cycling where the
two wheels stay in permanent contact with the ground. The LT is not,
under any circumstances, intended for “all-terrain” use or any kind of
competition. The LT is designed to be ridden by an adult with a mini-
mum height of 1.50 metres, a maximum height of 1.95 metres and a
maximum weight of 100 kg. The total permitted load is 80 kg maximum
on the rear luggage rack. The total weight limit is 198 kg including the
cyclist and their load. It must never be exceeded.

Loading
Loading is possible on the rear luggage rack. Front loading is possible
only if your LT is equipped with a suitable accessory, available from
your Retailer or DOUZE Cycles Technical Centre. The load must be pro-
perly attached to the structure. It must be organised according to the
mass of each object transported with the heaviest objects placed as
near as possible to the saddle and low down. They must not exceed
the width of the handlebars. Check that there is no risk of any object
falling during your ride.
Carrying people, children or adults, is also possible on the rear lug-
gage rack only. You can use it to carry one or two passengers without
exceeding the total limit of 80 kg. Various accessories are available to
improve the comfort and safety of passengers. Accessories that make
your luggage rack compatible with MIK HD and THULE EasyFit moun-
ting systems are available.
When the passengers get on and off, the bike must
be held by the cyclist to prevent it from falling.
Make sure that your reflectors and lights are visible
once you have added your load to the luggage rack.
