Aventon recalling Sinch.2 folding e-bikes

Published January 4, 2024

WASHINGTON (BRAIN) — Aventon is recalling about 2,300 Class 2 Sinch.2 folding e-bikes because they can accelerate unexpectedly, posing a crash and injury hazard. Aventon first announced a safety update to the bikes last August and has made a software update available to customers since then. It notified the CPSC at the time the problem was discovered and worked with them to make a voluntary recall announcement this month.

The e-bikes were sold in two colors (quicksilver and sapphire blue) with "Aventon" on downtube and "Sinch.2" on the chainstay.

The CPSC announcement says consumers should stop using the e-bikes and contact Aventon for a free repair, including a controller software update, toll-free at 866-300-3311 from 9 a.m. to 4 p.m. PT Monday through Friday, by email or online.

The company said they are asking that customers contact their local dealer if possible because the dealers have flash drives available for a quick software updates.  If the customer has no nearby dealers they should call Aventon directly. 

Before the CPSC announcement, "all Sinch.2 inventory in our warehouse was updated and drives were shipped to our retail partners for them to update their inventory as well as service customer bikes that were already in the market," the company told BRAIN.

According to the CPSC, there have been six reports of the Sinch.2 models accelerating unexpectedly, but no injuries reported.

The e-bikes were sold at bike stores nationwide and online at and from April 2023 through August 2023 for about $1,800.
