ride. The electric motor is turned off as soon as you stop pedaling. At the maximum aided speed,
the motor starts to reduce its power output until the aided pedals are turned off. For example,
the maximum aided speed is 25km/hr (15.5mph) in European countries. You may ride faster than
this maximum aided speed if you turn off the assisted pedaling function.

Safety
Please read the information of qualified and authorized professional distributors in the
user's manual.
Safety Equipment
It is recommended to turn the light on even when riding at daytime. As an electrically assisted bike,
the Darfon Innovation bike is subject to road traffic regulations, such as the German
Straßenverkehrs-Zulassungs-Ordnung (StVZO). The Darfon Innovation bike is equipped with the
lighting system required for active and passive parts when riding on a road, and an adequately
designed brake system as well. The lighting system features that following:
• Front and rear lights
• Front white reflecting mirror
• Rear red reflecting mirror
• Reflecting sheet on the spoke of the tires
• Yellow reflecting sheet on the pedals
For the safety of rider, please go to a BESV-authorized dealer for regular service of the e-bike.
Proper Accessories
You may need a helmet to ride an electric bike depending on the country you are in. However,
Darfon Innovation recommends you to wear a helmet that fits you and protective eyewear
regardless the requirement of helmet. Wear bright-colored clothing that catches attention when
on a Darfon Innovation bike for a joyride, and a comfortable pair of shoes that are fit for
pedaling. Familiarize yourself with local traffic rules and requirements and keep them in mind
when riding on a road. It is for the safety of yours and others on the road.
Pre-riding Check
Check the Tires and Wheels
While riding an electric bike, the tire valve may break if you sit one-sidedly on the bike. If this
happens, the tire will lose pressure and there is a risk of accident. Therefore, always check that
the valve is at the correct location. It has to extend from the edge of tire inclining towards the
right hand side. Correct the valve immediately if the position is off. Check the following every
time before you mount your bike:
• Check that the tires and wheels are intact without damage and whether the tires are pierced by
any foreign object. Damaged tire will lose pressure and further damage.
• The depth of tire treads.
• Normal activation refers to the two wheels rotating freely. If a wheel is not rotating in a perfect
circle, it is possible that the tire broken, has a damaged axle or worn spoke.
In addition, investigate the source of any unusual noise if necessary, and check the loads carried
and the tightened connection.
Check the Chain and Chain Cover
While riding an electric bike, the chain and cover that are not tightened may be slacking and
cause accident and injury. Make sure that the chain is engaged and tightened and that the cover
is secured every time before riding the bike. Check also that the chain and chain cover are
installed correctly to prevent falling off or sliding.
Handle the chain as instructed, particularly every time when the rear wheel is removed or
installed. Be extra careful in these situations to prevent damage to the chain and chain guard.

Proper Accessories
You may need a helmet to ride an electric bike depending on the country you are in. However,
Darfon Innovation recommends you to wear a helmet that fits you and protective eyewear
regardless the requirement of helmet. Wear bright-colored clothing that catches attention when
on a Darfon Innovation bike for a joyride, and a comfortable pair of shoes that are fit for
pedaling. Familiarize yourself with local traffic rules and requirements and keep them in mind
when riding on a road. It is for the safety of yours and others on the road.
Pre-riding Check
Check the Tires and Wheels
While riding an electric bike, the tire valve may break if you sit one-sidedly on the bike. If this
happens, the tire will lose pressure and there is a risk of accident. Therefore, always check that
the valve is at the correct location. It has to extend from the edge of tire inclining towards the
right hand side. Correct the valve immediately if the position is off. Check the following every
time before you mount your bike:
• Check that the tires and wheels are intact without damage and whether the tires are pierced by
any foreign object. Damaged tire will lose pressure and further damage.
• The depth of tire treads.
• Normal activation refers to the two wheels rotating freely. If a wheel is not rotating in a perfect
circle, it is possible that the tire broken, has a damaged axle or worn spoke.
In addition, investigate the source of any unusual noise if necessary, and check the loads carried
and the tightened connection.
Check the Chain and Chain Cover
While riding an electric bike, the chain and cover that are not tightened may be slacking and
cause accident and injury. Make sure that the chain is engaged and tightened and that the cover
is secured every time before riding the bike. Check also that the chain and chain cover are
installed correctly to prevent falling off or sliding.
Handle the chain as instructed, particularly every time when the rear wheel is removed or
installed. Be extra careful in these situations to prevent damage to the chain and chain guard.

BESV recommends that you shall always turn on the lighting system when riding the E-bike. In
case the lighting system can not be turned on, it must be checked by an authorized dealer for
safety.
Riding Manual
Assist Power Level of Electric Assisted Riding
A slippery pedal or riding the E-bike on the slippery pavement may cause the rear wheel
slipping and insufficient tire grip force. It will raise the emergency risks for the rider. In the case,
please turn off the pedal assistance. BESV E-bike assists a rider when she/he pushes hard on the
pedals. Therefore, the motor will be closed when the rider stops to push the pedals.
If the maximum power assisted speed (depended on countries) is exceeded, the pedal
assistance will be turned off. The assist power level is based on the selected assist level, such as
CRUSE, TOUR, and SPORT. By pushing the pedal, the speed sensor can detect the force more
effectively and activate the electronic control system more quickly to provide assistance. It
provide more particular advantage when riding the E-bike uphill.
Brake System
BESV E-bike supports hydraulic disc-brake equal to the same level of MAGURA MT4. If
necessary, it will provide quick and safe braking. The response of disc-brake is quicker than this
of drum-brake, especially riding on a slippery pavement. Hydraulic brake requires few hand
force to generate sufficient braking. To distribute the braking force on the two wheels, please
brake the two wheels at the same time. Please notice the following brake precautions:
• Riding the E-bike on a slippery pavement: The friction between the tires and the road is
decreased, and the water reduces the braking effects of the brake pad and disc. It will increase
the brake distance and emergency risks.
• Riding the E-bike on a slippery pavement shall reserve longer brake distance and practice the
brake more carefully to avoid the wheels are deadlocked.
• In case of braking the front wheel suddenly, the rear wheel may be lifted and raises unexpected
risks.
• Please apply the brakes on the front and rear wheels. When braking suddenly, please keep
your balance.
The pedal assistance of the E-bike is controlled and interrupted by the brake (or stopping
pushing the pedals). If you are not familiar with the hydraulic disc brakes, please practice and
test the brakes in a place with poor traffic and the pavement supporting high tire grip. Avoid
continuous braking. When riding the E-bike on a long slope downhill, please shortly and stably
apply the two brake together. When you release the brakes intermittently, they can be cooled
down again. In case of overheating indications, please stop riding immediately. The overheating
indications include increased hand force, odor accumulation, and loud noise.Please cool down
the brake system before riding. Humidity will reduce the braking effect and cause the tires
slipping more easily. Riding the E-bike on a wet pavement shall reserve longer brake distance,
slow down the speed, and brake carefully.
Brake System Wear
The wear of brake pad and disc are caused by friction. The more riding in a mountainous terrain
and rain or mud, the greater the wear of the E-bike. Since the wear of brake pad and disc can not
be evaluated based on the brake lever, please check it before each trip. The brake pad must be
replaced by a qualified dealer.
