The BYD B12DS is a battery-electric double-deck city bus offered by Chinese manufacturer BYD Auto Industry (比亞迪). Designed for the Singapore market, it is a right-hand-drive vehicle featuring 3 doors and 2 staircases.
The bus was first spotted in Singapore in October 2024. Delivered in a Lush Green livery, this bus is possibly a demonstrator unit being offered to the Land Transport Authority (LTA) for revenue service trials.
In line with LTA’s ongoing efforts to rapidly electrify the public bus fleet, half of all public buses will be electric by 2030. Detailed coverage of this rollout can be found at Electric Buses in Singapore.
SITCE 2024
The bus was exhibited at the LTA-UITP Singapore International Transport Congress & Exhibition (SITCE) in November 2024, bearing a red advertising wrap for BYD, advertising the bus’ key specifications.
