Potential risk of suspension fork failure in Stromer ST3, ST5 and ST7 models

Your driving safety is our top priority at all times. With this notification, we would like to inform you about a possible safety risk.

Stromer is voluntarily recalling about 6.500 front suspension forks of the brand “WREN”, which were installed on its ST3, ST5 and ST7 Speed-Pedelecs. The suspension fork steerer tube can fatigue prematurely and crack, break or separate during use and, as a result, the rider may lose control of his bike, posing fall and injury hazard.

Stromer has received 15 reports of suspension fork steerer tubes failures, with eight associated customer injuries.

AFFECTED BIKES

The front suspension forks have been installed on about 6.500 ST3, ST5 and ST7 Stromers and mainly sold in Europe and the US. Affected customers will be notified by Stromer directly and asked to verify whether a WREN front suspension fork has been installed on their bikes.

IMMEDIATE STOP OF USE

For safety reasons, do not use your Stromer until the WREN suspension fork has been replaced. A suspension fork failure may lead to loss of control and injury.

REPAIR ACTION

Replacement parts are currently in production and we will notify you once the remedy is available. Stromer expects to send a notification by the start of 2026 for a free-of-charge suspension fork steerer tube repair at an authorized Stromer dealer.

Please contact safety@stromerbike.com for any customer inquiries regarding this recall. Stromer sincerely apologizes for the inconvenience and thanks all customers for their cooperation and understanding.

Possible risk of fork breakage in a production series of Stromer Bikes ST1, ST3 and ST5

Your driving safety is our top priority at all times. With this notification we would like to orient you about a possible safety risk.

Regrettably, we have recently discovered that the forks of a small number of S-pedelecs of the ST1, ST3 and ST5 models have a manufacturing defect. Extensive quality and stress tests conducted by an external testing institute prove that this is a sporadically occurring component defect in the manufacturing process of a certain production batch.

Specifically affected are around 500 bikes of the models ST1, ST3 and ST5 sold in the EU and Switzerland. In the course of the measures undertaken by Stromer, 414 forks have already been exchanged.

Affected customers have been informed by Stromer directly by e-mail and by letter. They can have a free fork exchange carried out immediately via an authorized STROMER dealer of their choice. The use of the affected bikes must be discontinued for safety reasons. There is a risk of fork breakage as a result of use, leading to possible injury.

myStromer AG would like to apologize expressly and sincerely for the inconvenience and thank the affected Stromer owners for their understanding.
