Biki, Honolulu’s bikeshare service, is offering free rides to new users on Sunday, March 4.

Bikeshare Hawaii said it will give away one free, ride, up to 30 minutes, to new Biki users, as part of a promotion to achieve its goal of achieving 4,000 trips in one day. Currently, Biki says it averages 2,008 rides per day.

To get the free ride, new users can enter the promo code, BIKI4K on the Biki mobile app or at any of Biki’s 100 kiosks located from downtown to Diamond Head.

The promo code will be valid from 12 a.m. to 11:59 p.m. on March 4, and can be redeemed by new users only as well as once per person. Normal usage fees will kick in after the 30-minute mark. Regular fares for single rides are $3.50 for each 30 minutes of use. A $50 security will still apply and will be released within three to five business days after the bike is returned.

Biki riders must be 16 years and older, and must register with a credit or debit card. Riders can download the Biki App for a map of the stations. Prizes will be randomly awarded throughout the day, said Biki, to thank all participants for helping it reach its new record attempt.
