The European Bicycle Manufacturers' Association has filed an anti-dumping complaint with the European Commission against cheap Chinese e-bike imports.
The Commission less than a month to determine whether to start an investigation.
The EBMA is also preparing a related complaint alleging illegal subsidies and asking for registration of Chinese e-bike imports.
Bicycles have already been a flashpoint, reports Reuters. "The EU blamed China last December for scuppering a global environmental trade deal by insisting that bicycles be included as a tariff-free green product."
Chinese bicycles have been subject to EU anti-dumping duties since 1993.
EBMA says more than 430,000 Chinese e-bikes were sold in the EU in 2016, a 40 percent increase on the previous year, and forecasts the figure will rise to around 800,000 in 2017.
