A cyclist riding what appears to be an illegally modified e-bike crashed into a car in Ubi after allegedly attempting to overtake a BMW, according to footage shared online.
The incident reportedly happened along Ubi Avenue 1 at around 1.57pm on 13 August 2026. The dashcam footage, shared by SG Road Vigilante, shows the camcar travelling behind a lorry before traffic slows down.
According to the camcar driver’s account, the lorry ahead stopped, prompting the driver to brake normally. When traffic began moving again, the driver heard a loud impact from behind and discovered that an e-bike had crashed into the rear of the car.
E-Bike Allegedly Failed To Slow Down
After reviewing the dashcam footage, the driver reportedly believed the e-bike had not slowed down sufficiently before hitting the car.
The rider was allegedly attempting to move through traffic while overtaking a BMW when the collision occurred. The impact left the e-bike behind the camcar, while the car driver got out to inspect what had happened.
What apparently surprised the driver even more was the rider’s response. According to the account accompanying the video, the cyclist asked the driver why he had braked.
The incident has since attracted a wave of reactions online, with many commenters questioning the rider’s decision to overtake in traffic and whether the e-bike complied with Singapore’s rules.
Throttle E-Bikes Are Not Allowed On Singapore Roads
Under Singapore’s regulations, an approved power-assisted bicycle must obtain power assistance through pedalling. A throttle that allows the bicycle to move under motor power without pedalling is not permitted.
The rules surrounding power-assisted bicycles are designed to ensure that such devices remain within the permitted technical and safety requirements. E-bikes that are illegally modified may face enforcement action if found to breach these requirements.
The footage has therefore prompted renewed discussion about illegal modifications, road safety and whether riders understand the rules governing e-bikes in Singapore.
Several commenters called for the matter to be reported to the authorities, while others questioned whether the bicycle would be inspected following the collision.
Online Users Question Rider’s Reaction
The comments section quickly filled with criticism of the rider’s apparent reaction. Some users argued that the driver had every reason to brake when traffic ahead stopped, while others focused on the apparent speed of the e-bike.
One commenter sarcastically suggested that the rider should have asked, “Why you never brake?”, highlighting the frustration among viewers who felt the collision could have been avoided.
Others raised concerns about the financial consequences of a collision between an e-bike and a car, particularly if the rider is unable to cover repair costs. Some commenters also called for stronger enforcement against illegally modified e-bikes.
However, the available footage only captures the incident from the dashcam’s perspective. It does not independently establish the cyclist’s speed, the exact modification status of the e-bike or liability for the collision.
The video nevertheless serves as a reminder that overtaking in busy traffic requires careful judgement, particularly when road users are slowing or stopping unexpectedly.
For motorists, cyclists and other road users, maintaining a safe following distance and anticipating sudden changes in traffic can help reduce the risk of collisions. As the footage continues to circulate online, the incident has once again fuelled debate over e-bike regulations and road safety in Singapore.
