A 49-year-old woman died after she was riding an electric bike in Manhattan and struck a curb, cops said Saturday.

Dayanara Deschamps Betances was zipping northbound on her e-bike, with a 75-year-old passenger seated behind her, in the right lane of Amsterdam Ave. at W. 181st St. in Washington Heights on May 2 around 3:19 a.m., when she struck a curb.

Both Betances and the man were ejected from the bike and hit the sidewalk.

EMS transported Betances to Columbia University Irving Medical Center where she died.

The older man didn’t sustain any injuries from the accident.

Betances lived in Washington Heights, cops said. She was seven blocks away from her home.

The NYPD Highway District’s Collision Investigation Squad is investigating the collision.
