Rivian's Also division apologizes as TM-B e-bike rollout stalls

Also, the micromobility offshoot of Rivian, revealed its high-tech TM-B e-bike last year, promising features such as a USB-C-charged battery, removable seat post and a software-driven pedal-by-wire system. Initial delivery timelines targeting spring 2026 were later pushed to summer, but the bike has yet to be shipped as fall approaches. In a 661-word Reddit post, product manager Saul Leiken apologized to reservation holders, explaining that a surge in AI-related demand has strained the supply of printed circuit boards and integrated circuits needed for the bike’s electronics.

Battery packs of 538 Wh or 808 Wh also exceed current regulatory limits, forcing negotiations with safety agencies. Additionally, the DreamRide drivetrain’s high-precision manufacturing has slowed the production ramp-up. Also emphasized that it chose to uphold quality standards rather than rush an unfinished product, while acknowledging poor communication with customers.
