Congratulations on the purchase of your Fahrbike! You have chosen a bike that will give you an unparalleled
riding experience and you have made a wise choice.
Please read this Owner's Manual carefully before using your new e-bike. It is your reference for assembly,
maintenance, and safety.
If you are not confident in assembling the bike yourself, we strongly recommend that you have your bike
assembled by a qualified bicycle mechanic.
If you have questions or need assistance, please contact us directly.

Introduction

Safety Check
02FAHRBIKE-ROADSTER73
1
Please check the following components: Handlebars, stem, pedals, crank arms, and wheels. Make sure they
are properly assembled and tightened. Even if some of the components are pre-assembled, each part must be
tightened to the specified torque. If you do not notice a loose component, it may come loose during use and
cause serious injury.
It is recommended that the above safety checks be performed every 200 - 300 km (120 - 180 miles) or when
the bicycle has not been used for three weeks.
Wheels: An important part of assembling your bike is attaching the front and rear wheels and checking
that the wheel axle nuts are tight. Properly assembled wheels are essential for the safe use of the bicycle.
Tires: Both tires must be inflated according to the specifications in the manual. Failure to do so will reduce
performance, increase tire wear, and compromise your safety.
Crank and pedals: Make sure the crank arms and pedals are tightened to the specified torque. A required
tool for the crank: 8 mm hex key, recommended tightening torque 30-35 Nm. Required tool for the pedals:
15 mm wrench, recommended torque 35-40 Nm.
Brakes: Make sure the brakes are working properly and are properly secured. When braking, apply the rear
brake first, then the front brake. Incorrect application of the brakes can result in serious injury.
Throttle: The throttle mechanism can be used to partially or fully activate the engine power. Inexperienced
users should be a bit more careful when operating the throttle for the first time. The throttle function is
deactivated when the pedal assistance is set to "0".

Users must familiarize themselves with the power controls before riding. It is strongly recommended that you
ride your new bike in an open area and set the assist level to "0". Once you become accustomed to operating
your bike, gradually increase the assistance level.
It is a good practice to keep your hands over the brake levers. The brake levers are equipped with motor
protectors that shut off motor power when activated. If you lose control for any reason, immediately apply the
brake levers to shut off motor power. Do not attempt to stop your bike with your feet as this may cause you
to lose your balance.
When walking or carrying your bike, turn off the power to avoid accidentally turning on the motor. If the
motor is accidentally turned on, immediately apply the brakes to cut the power to the motor.
