Klosterneuburg, July 5, 2023: woom, the Austrian manufacturer of bikes for kids and teens, is reaching out to its customers with a maintenance notice: woom ORIGINAL bikes from model years 2018 to 2021 that have a single (silver) stem clamp bolt require a service. Customers can easily identify if their bike is affected by using an online tool to verify and, if necessary, order their free woom ORIGINAL Stem Maintenance Kit.

The maintenance notice applies to woom ORIGINAL models from model years 2018 to 2021 in sizes 1, 1 PLUS, 2, 3, 4, 5, and 6. The stem of these bikes is secured with a single silver bolt. There is a slim likelihood that the stem could become loose or detach. The risk is increased when the stem clamp bolt is not fully tightened to the recommended torque of 10 Nm. woom ORIGINAL bikes from earlier model years (–2017) and after 2021 are not affected. Additionally, the woom OFF, woom OFF AIR, woom NOW, and woom UP are not affected.

Customers are now being encouraged to use the woom Online Stem Checker to identify their bike and determine if it is affected. If so, they can immediately order a free woom ORIGINAL Stem Maintenance Kit, which includes a torque wrench, a 5mm hex key, assembly paste, and accompanying instructions. Equipped with their Stem Maintenance Kit, customers can service the stem at home and ensure that their woom bike is safe to ride again. As an additional option, customers in Austria and Germany will receive a voucher for a complimentary stem service at participating woom dealers.
