Bike inspection
eBike Lab is responsible for bike inspections. Official full inspection, using the UCI European technical standard as a reference — including wheel measurements and software inspection — applies only to ELITE (UCI Drive Units). SL, OPEN and OPEN PLUS will be inspected to verify that motor assistance cuts off at 25 km/h. This does not limit the bike’s speed when riding without motor assistance or imply UCI sanctioning or certification.
