Rivian Spinout Also Apologizes for E-Bike Shipping Delays

Rivian’s Also has issued a formal apology for the continued shipping delays of its high-tech TM-B electric bike, acknowledging that customers have waited far longer than promised. The futuristic bicycle, which debuted as a standout product from Rivian’s micromobility spinoff last year, features a software-controlled pedal-by-wire system, a removable seat post, and a USB-C chargeable battery. These innovative design elements initially generated significant excitement in the e-bike community, setting the TM-B apart from conventional models. However, the very complexity that made the bike unique has now become a major obstacle in getting units into the hands of early adopters.

Originally, Also projected that deliveries would begin in spring 2026, with timelines later shifting to summer. As autumn approaches, no customers have received their bikes, leading to growing frustration among reservation holders who have taken to platforms like Reddit to voice their concerns. In an unusual move for a hardware company, Also addressed these complaints directly on the forum through Saul Leiken, the company’s product manager. Leiken posted a detailed letter explaining that the hold-up stems from a commitment to strict quality standards rather than rushing an unfinished product to market.

Leiken identified several technical hurdles contributing to the delay. He pointed to significant supply chain challenges exacerbated by the AI boom, specifically noting difficulties in sourcing adequate printed circuit board (PCB) and integrated circuit (IC) materials. In instances where original components were unavailable, the engineering team had to identify alternative materials that deviated from the initial design, necessitating additional testing and validation work.

The bike’s powertrain and battery systems have also faced regulatory and manufacturing scrutiny. The TM-B offers battery packs of either 538Wh or 808Wh, designed to provide up to 100 miles of range. However, the system’s 240W power delivery exceeds current regulatory guidelines, requiring Also to collaborate with standards groups to develop new safety and testing protocols. Additionally, the DreamRide drivetrain, a sophisticated pedal-by-wire mechanism that uses a generator motor on the crank and a rear traction motor connected via a Gates Carbon belt drive, demands high-precision manufacturing. Leiken admitted this requirement has slowed production ramp-up to ensure quality control.

While Rivian aimed to create one of the most technologically advanced e-bikes ever produced, the timeline slippage highlights the difficulties of scaling such complex hardware. Leiken conceded that the company could have improved its communication regarding these anticipated challenges. Addressing the balance between speed and quality, he stated: “With any complex and technology-laden product, we have a choice,” he said. “As we ramp production we can relax standards against an original timeline or we can hold to a high standard and face potential delays. We believe our decision to hold that standard was, and is, the right one. And, at the same time, we agree that we should have been more communicative along the way.”
