Fork steerer
Source: EN 15194:2017: part of a fork that rotates
around the steering axis of a ebike frame head
tube. It is normally connected to the fork crown or
directly to the fork legs, and is normally the point
of connection between the fork and the handlebar
stem.
Fracture
Source: EN 15194:2017: unintentional separation
into two or more parts.
Maintenance
Source: DIN 31051: maintenance is generally per-
formed at regular intervals and often carried out
by trained technical staff. This ensures a maxi-
mum service life and low wear and tear for the
maintained items. Proper maintenance is often
also a pre-requisite for providing a warranty.
Manufacturer
Source: Directive 2006/42/EC on Machin-
ery,17.05.2006 Any natural or legal person who
designs and/or manufactures machinery or partly
completed machinery covered by this Directive
and is responsible for the conformity of the ma-
chinery or the partly completed machinery with
this Directive with a view to its being placed on the
market, under his own name or trademark or for
his own use.
Maximum continuous power rating
Source: BULLS: the maximum continuous power
rat-ing is the maximum power for the electric
motor output shaft during 30 minutes.
Maximum permitted total weight
Source: EN 15194:2017: weight of the fully as-
sembled ebike plus the rider and gear, as
specified by the manufacturer.
Maximum saddle height
Source: EN 15194:2017: vertical distance from
the ground to the point where the top of the seat
surface is intersected by the seat-post axis, meas-
ured with the saddle in a horizontal position and
with the seat-post set to the minimum insertion-
depth mark.
Maximum tire pressure
Source: EN 15194:2017: maximum tire pressure
recommended by the tire or rim manufacturer for
a safe and efficient performance. If the rim and
tire both indicate a maximum tire pressure, the
maximum inflation pressure is the lower of the two
pressures indicated.
Minimum insertion depth
Source: EN 15194:2017: mark indicating the min-
imum insertion depth of handlebar stem into fork
steerer (fork stem) or seat post into frame.
Model year
Source: BULLS: the model year refers to the first
production year that the series-manufactured
ebike was manufactured in the version in ques-
tion and is not always identical with the year of
manufacture. The year of manufacture may be be-
fore the model year in some cases. If no technical
modifications are introduced to the series,
produc-tion may continue of ebikes from a
previous model year.
Mountain bike
Source: ISO 4210 - 2: ebike designed for use off-
road on rough terrain, on public roads, and on
public pathways, equipped with a suitably
strengthened frame and other components, and,
typically, with wide-section tires with coarse tread
patterns and a wide range of gears.
Negative deflection
Negative deflection or sag is fork compression
caused by body weight and gear (e.g. a backpack),
their sitting position and the frame geometry.
Off-road rough terrain
Source: EN 15194:2017: rough gravel tracks, for-
est trails and other generally off-road tracks where
tree roots and rocks are likely to be encountered.
Operating instructions
Source: ISO/DIS 20607:2018: part of the user in-
formation that machine manufacturers provide to
machine operators; it contains guidance, instruc-
tions and tips related to the use of the machine in
all its life cycle phases.
