1. Bicycles with pedal assist
1.1 What is the difference between "electrically pedal-assisted" and "electrically powered"?
Your Bunch cargo bike is electrically pedal-assisted; that is completely different from electrically powered.
Electrically pedal-assisted means that you will only be assisted by the electric motor if you yourself apply
(sufficient) pedaling force to the pedals. If you stop pedaling, the motor will also stop "helping" you. In an
electrically powered vehicle, you only have to keep a button pressed in or operate a lever, and the vehicle will
drive without you applying your own pedaling force.
1.2 Cycling with pedal assist
Cycling with pedal assist gives you the feeling that you are always "riding with the wind behind you," and the
experience is quite different from cycling without assist: it makes it easy to start from a stationary position or
on a hill, or to ride against a headwind, and of course you can reach higher speeds comfortably. Our advice is
first to try out The Coupe on a quiet bike path, for instance, without children in the cargo box and also with
limited assist (see Display and operation). Note that the rear frame will tilt slightly to the left or the right on
curves; this is completely normal and is specially designed to optimize riding behavior on curves and make it
feel more natural.
Set the pedal assist to a higher level once you feel like you have the bike "under control." The maximum
speed that may be reached with the assist is legally specified at 20mph; this means that if you cycle faster
than 20mph, the motor will stop providing assistance.
Note: We recommend greatly reducing the speed on curves to prevent the risk of tipping over. Please keep in
mind that 20mph is quite fast for a cargo bike; not everyone in traffic is ready for that yet!

2.2 Overview of functions
Speed indicator: Screen showing current speed (SPEED), maximum speed (MAXS) and average
speed (AVG).
Speed displayed in kilometers or miles: You can switch between kilometers or miles on the
display.
Intelligent charge indicator: Stable display of the battery status is guaranteed by an optimization
algorithm. This avoids the problem, common to many displays, of fluctuating display of the battery
level.
Operation of lights: The headlight, taillight and screen display illumination switch on and off
automatically, depending on the light conditions.
Screen illumination: Choose between different lighting levels, from level 1 (dim) to level 5 (bright).
Assist level indicator: This indicates the current assist mode (level 0 to 5).
Trip distance indicator: The maximum distance is reached when 99999 appears on the screen. You can
display the distance for a single trip (TRIP) or the total distance (TOTAL).
Error indicator
Pedal assist
The service lights will appear depending on the charge status and the total distance traveled. The
display automatically estimates battery life and issues a warning if the set number of battery
charges is exceeded. A warning is also issued when the total distance traveled exceeds the set
value. This function can be turned off.

the WALK symbol appears.
I - Lighting:
The characters will light up as soon as the headlight and taillights are turned on.
J - Distance mode:
You can display either the distance for a single trip (TRIP) or the total distance (TOTAL). The maximum
distance is reached when 99999 appears on the screen.
K - Battery charge status:
