Rivian's e-bike spinoff will begin delivering its TM-B e-bikes to customers in the United States following several months of delays [1, 2].
The move marks a critical transition for the startup as it attempts to fulfill outstanding orders after failing to meet its initial production timeline. For the company, the delivery phase is the first real test of its ability to scale operations independently from its parent company's automotive infrastructure.
The company originally scheduled the launch of the TM-B for spring 2026 [1]. However, production setbacks pushed the date back, leaving customers waiting for several months [1, 2].
Reports on the exact timing of the shipments vary slightly. One source said deliveries are slated to begin next week [3], while another said the process will start in August 2026 [4]. The bikes will be shipped from a warehouse located within the U.S. [4].
The TM-B is designed to enter a competitive e-bike market where timing and reliability are key to consumer trust. By finally moving into the shipping phase, the spinoff aims to resolve the backlog created by the missed spring window [1, 2].

The transition from production to delivery is a high-risk phase for hardware startups. By missing the spring window, the company lost the peak seasonal demand for e-bikes. The successful rollout of the TM-B from its US warehouse will determine if the spinoff can maintain the brand prestige associated with Rivian or if the delays have permanently damaged its market entry strategy.
