I sure can! To add a roof rack to the flush rails on your 2024 Kia Niro EV, I recommend the roof rack by Yakima which includes the following parts:
Yakima JetStream Crossbars - Aluminum - Black - 50" Long - Qty 2 item # Y00425
SightLine Towers for Yakima Crossbars - Flush Side Rails - Qty 4 item # Y64AR
SightClip Fit Kit for Yakima SightLine and RidgeLine Roof Rack Towers item # Y27AR
This aero bar roof rack system has a 165 lbs capacity. I recommend adding the Yakima Same Key System... view full answer...
The 35 lb per bike weight capacity of the Hollywood Racks Destination # HR4000 is for each bike position - the trays are only able to safely handle up to 35 lbs each. Since your bikes weight more than that we need to find you an alternative (the Destination is one of my favorite racks so I definitely see the appeal of it).
The best rack for your situation is the Hollywood Racks Sport Rider SE Bike Rack for 4 Bikes # HR1400Z as it has a weight rating of 50 lbs per bike and secures them... view full answer...
The Curt Trailer Hitch item # C77NR weighs 30 lbs. This hitch is confirmed to fit the 2023 Kia Niro EV.
If you are planning on towing you will also need a wiring harness item # 119250KIT and a ball mount kit item # C45534. view full answer...
