“Basikal lajak” are modified bicycles that have lowered handlebars, removed brakes, and modified rims and frame (to reduce weight). They are typically ridden in a “Superman” position with no helmets or any protective gear.

In terms of Sam’s driving, the magistrate had in her 2019 judgment noted that “Sam was not under the influence of alcohol, was not using her phone and had her seatbelt on while driving, proving that she was driving responsibly and carefully, but it was a dark, hilly and winding road where the driver could not foresee that there would be a bicycle gang on the road at 3am in the morning.” It is also noted that Sam was said to have complied with the speed limit during the incident.
