Incident Overview

According to a report filed with the CPSC on April 2, 2026, the owner of a 2024 HeyBike Cityscape electric bike described two separate incidents in which the bike suddenly and inexplicably accelerated without the throttle being touched. In October 2025, the consumer was riding the bike when it surged forward as she turned a corner. She was thrown onto the sidewalk, resulting in a sprained ankle, road rash, and a broken foot. A second incident occurred two weeks before the report: as the consumer turned on the bike and walked it through a school yard, it again accelerated on its own, causing severe bruising and welts on her legs and hips.

The reporter noted that the school's CCTV camera captured the second event, showing the bike suddenly accelerating without input. The consumer stated she had reported the issue to her wife multiple times before the injuries occurred. The bike was purchased in July 2024 from Amazon.com. The report did not indicate whether the manufacturer had been contacted or if any repairs were attempted.

Safety Concerns

Immediate Dangers: Unintended acceleration of an e-bike while riding or walking it can cause the rider to lose control, leading to falls, collisions with obstacles, or being thrown from the bike. The force of sudden acceleration can result in fractures, sprains, and soft tissue injuries, as seen in this incident.

Long-Term Risks: If the underlying design or component defect is not corrected, the risk of future accidents remains. Continued use of a bike with known acceleration issues could lead to additional injuries, potentially more severe, especially if the rider is in traffic or near pedestrians.

Who Might Be Affected: The primary person at risk is the rider, but bystanders—especially children in settings like school yards—also face danger from an out-of-control e-bike. In this case, the second incident occurred in a school yard, raising concerns about harm to others.

Warning Signs: The described behavior—sudden, throttle-independent acceleration—is itself a warning sign. Any instance of the bike moving without rider input should be taken seriously. Riders may also notice hesitation or unexpected power surges during normal operation.
