In her second year as a professional Niewiadoma shone as one of the best young riders in the peloton, giving Poland results it had never had in women's cycling.
She once again demonstrated her climbing abilities with 6th place in the inaugural edition of Strade Bianche Donne and 5th in the prestigious World Cup race La Flèche Wallonne Féminine.
She also took a podium spot in the Dutch race Boels Rental Hills Classic, finishing behind Lizzie Armitstead and Emma Johansson.
In June she won Emakumeen Euskal Bira, a five-day stage race in the Basque Country, and won silver in the elite women's road race at the European Games.

Despite being only 21, Niewiadoma started the season's biggest race – the Giro Rosa – as one of Rabo–Liv's leaders.
She quickly assumed the lead of the young rider classification and held on to the top places on the mountain stages.
She then clocked the fifth-fastest time on the demanding route of stage 8, a 21.7-kilometre (13.5-mile) time trial, and climbed up to 4th overall with just one mountaintop finish to go.
The long climb to San Domenico di Varzo proved decisive and Niewiadoma crossed the line in 7th, finishing 5th overall, winning the white jersey for best young rider and celebrating Anna van der Breggen's overall success.
With those results under her belt Niewiadoma led the Polish national team at the European Road Championships in Tartu and took gold in the women's under-23 road race, bridging to the leading group on the last lap and claiming the sprint ahead of Italy's Ilaria Sanguineti and fellow Rabo–Liv rider Thalita de Jong.
She concluded the season at the World Championships in Richmond, being a part of a Rabo–Liv squad that secured bronze in the team time trial event.
She also led the Polish team in the elite women's road race and sprinted to 7th place.
