Rivian’s Also apologizes for delays in shipping futuristic e-bikes

Rivian’s micromobility spinoff Also says deliveries of its high-tech TM-B electric bike are delayed, frustrating early customers. The e-bike drew attention for features like a USB-C-chargeable battery, removable seat post, and pedal-by-wire control system, but those same innovations appear to be slowing production.

The delay highlights how ambitious hardware startups can struggle when novel design choices meet real-world manufacturing constraints. As e-bikes become more software-defined, companies may face growing pressure to balance innovation with reliability, serviceability, and predictable delivery timelines.
