6. General Performance Criteria
The vehicle representative of the type submitted shall not display any deterioration in the direct
control of the vehicle which might be observed by the driver or by any another road user when
the vehicle in question is in the state defined in C.4 (EN 15194 Annex C).
Section C.4.6.2.1 in Annex C: A vehicle is deemed to fulfil the requisite conditions if, during the
tests carried out in the manner required by this clause, there are no abnormal changes in speed
of the vehicle’s drive wheels, there are no signs of operational deterioration which might mislead
other road users and there are no other noticeable phenomena which could result in a
deterioration in the direct control of the vehicle.

7. General Test Information
The bicycle was arranged according to EN 15194 in the test chamber. The bicycle was positioned
in a fixture there the bicycle-pedals were driven by an adjustable pneumatic motor and the back
wheel was loaded with an appropriate load for each test moment. The speed of the pedals was
adjusted until assistance speed conditions were reached.
Emission tests was performed in these EUT conditions:
- A load applied in order to test at 75% ±10% of the continuous rated power declared by
the manufacturer.
- Front-wheel activated by an external motor to obtain the front light functions. Standstill
mode of assistance part.
Immunity tests were performed in these EUT conditions:
- Standstill mode.
- 90 % of the “start-up assistance mode”.
- 90 % of the design maximum assistance speed.
The EUT was verified by monitoring the back-wheel speed and displayed data on Shimano STEPS
display.

Requirement: Criterion acc. to C.4
Result: PASS
Test Result: Criterion acc. to C.4
Test Description
The EUT was placed 1 dm over the chamber floor. The distance from antenna varied dependent of which polarization used.
The EUT was then subjected to radiated EM fields from 20 – 2000MHz.
These antenna types was used for each frequency band:
Antenna BBAE 9179 and VHBD 9134 was used at EM fields of 20-80 MHz.
Bicon elements and VHBD 9134 was used at EM fields of 80-200 MHz.
Horn antenna AH-220 was used at EM fields of 200-1000 MHz.
Horn antenna Emco 3115 was used at EM fields of 1000-2000 MHz.
The RF signal was swept in frequency with a 1% interval and with a dwell time of 2 seconds per frequency.
The EUT was verified by monitoring the back-wheel speed and displayed data on Shimano STEPS display.
Test conditions: 1. Standstill mode
2. 90 % of the “start-up assistance mode”.
3. 90 % of the design maximum assistance speed.
