Incident Overview

In late 2023, the consumer's Aventon Pace 500.2 suffered a thermal event during normal use, where the battery terminals melted and fused the battery to the frame. The manufacturer replaced the unit with a Pace 500.3 in January 2024. However, in December 2025, with fewer than 800 miles of use, the replacement unit experienced the exact same failure while the bike was in operation. The electrical terminals reached temperatures high enough to melt high-density plastic and weld metal components together. No impact or improper handling preceded the incident.

The consumer described this as a systemic design or manufacturing defect that creates a significant fire and burn hazard. The heat generated at the terminal interface was sufficient to melt the battery casing, posing a direct risk of lithium-ion battery ignition. Because the terminals fused together, the battery could not be removed from the frame, preventing the user from isolating the fuel source in the event of a fire. The failure occurred on two different model generations (.2 and .3), suggesting the underlying electrical resistance issue has not been addressed. The report is available on SaferProducts.gov under Report ID 5928730.

Safety Concerns

Immediate Dangers: The thermal event at the battery-terminal interface can cause the battery casing to melt, potentially leading to lithium-ion battery thermal runaway. This can result in intense heat, flames, and toxic smoke, posing an immediate fire and burn hazard to the rider and nearby persons.

Long-Term Risks: Even if a thermal event does not lead to full ignition, repeated heating cycles can degrade battery cells and connectors, increasing the likelihood of a future catastrophic failure. The pattern of recurrence across two model generations indicates a systemic issue that may affect other units.

Property Damage Potential: The inability to de-energize the battery by removing it from the frame means that if a fire starts, the battery continues to supply fuel to the flames. This can escalate property damage, especially if the e-bike is stored in a garage or home.

Warning Signs: The incident report notes that the failure occurred without warning during normal use. However, any signs of overheating, such as a hot battery or melting near the terminals, should be treated as an urgent indicator of an impending failure.

What Our Clients Say

What Consumers Should Do

Stop Using Immediately: If you own an Aventon Pace 500.2 or Pace 500.3, discontinue use until the battery-terminal connection can be inspected by a qualified technician. Continuing to ride increases the risk of a thermal event.

Preserve the Product: Keep the e-bike in its current condition, including any melted or fused components. Do not attempt to separate the battery from the frame, as this could destroy evidence needed for investigation.

Document the Incident: Take clear photographs and videos of any damage, including melted plastic, scorch marks, or fused terminals. Save purchase receipts, warranty documents, and any communications with the manufacturer.

Contact the Manufacturer: Report your concerns to Ride Aventon, Inc. Even if your warranty has expired, the recurring nature of this defect may warrant a safety response.

Report to the CPSC: File a report with the Consumer Product Safety Commission at SaferProducts.gov to help regulators identify patterns of defects.

Check for Recalls: Monitor CPSC.gov for any recall announcements related to Aventon Pace 500 series e-bikes.
