United KingdomStromer ST3, ST5 and ST7 S‑pedelec bicycles fitted with WREN front suspension forks (bikes with automatic pedal support) are affected; they can be identified by the model names and the fitted WREN suspension fork. The WREN forks can fail prematurely — cracking, breaking or separating during use — which may cause the rider to lose control and be injured, and they do not meet the General Product Safety Regulations 2005. Stromer has contacted affected customers and advised they stop using the bikes immediately; replacement forks are being produced and owners should contact their authorised dealer to arrange a free replacement when notified.
