Anyone taking their bicycle on a BTS train on Sunday, the day of the "Bike for Mum" event, will be given a free ride between 6am and midnight.
Bangkok Mass Transit System Plc, operator of the elevated BTS skytrain system, made the announcement on its Twitter @BTS_Skytrain on Thursday
The exemption also applies to cyclists boarding a bus on the Bangkok BRT (bus rapid transit system) but on the condition that their bicycles must be the folding type only.
Owners of both folding and non-folding bikes are offered free rides on the BTS SkyTrain system.
