Mobike, ofo, SG Bike and GBikes have submitted their applications to the Land Transport Authority for a full licence to operate dockless bicycle services.
GBikes, which started in May last year, will cease its bicycle sharing service on 7th July, the same day a new licensing regime kicks in.
The Government has issued new guidelines that require all new private developments to provide bicycle parking spaces.
Bike-sharing users who park indiscriminately more than three times will be temporarily banned from renting from all operators for a full year.
The Singapore-MIT Alliance for Research and Technology has found that dockless shared bicycles are only used for half an hour a day on average.
Bike-sharing firms in Singapore will soon come under a licensing regime as part of the Land Transport Authority's plan to curb indiscriminate parking.
Bike-sharing firms will have to ensure that their bicycles are parked within designated zones by the end of the year.
The Land Transport Authority announced that it had signed an agreement with bicycle-sharing firms and NParks to encourage the responsible use of shared bikes.
Bicycle-sharing firm GBikes joins oBike, Mobike, ofo and SG Bike after quietly rolling out its bicycles for almost five months.
