A record number of journeys were made by people using the NS shared bike scheme last year. In total, users made 3.2 million trips, a rise of 33% on 2016, the AD said on Friday.
NS scrapped the €10 subscription fee in January last year and the number of people using the distinctive blue and yellow two-wheelers has since soared from 200,000 to 500,000.
It costs €3.85 to rent a bike and some 15,000 are now in regular use, spread across 300 railway stations nationwide. NS is planning to order a further 6,000 bikes this year, spokeswoman Corien Koetsier told the paper.
