Rivian's micromobility spinoff Also unveiled the TM-B electric bike last year, and it quickly caught attention in the e-bike market. The bike stood out with a software-controlled pedal-by-wire system, USB-C rechargeable battery, and a removable seat post—features that represented a different approach to e-bike design.

The company has now apologized for delays in shipping the TM-B to customers, who have grown frustrated with the wait. While the snippet does not provide specific details about revised delivery timelines or reasons for the delays, the apology signals that Rivian's Also division has faced challenges in meeting its original shipping schedule.
