Rivian’s electric mobility spinoff also announced a $3,500 starting price for its first e-bike, called the TM-B. The startup unveiled the shape-shifting e-bike last month, with options for a limited launch edition, performance edition or base model. During the unveiling, it was also said that both the Launch and Performance TM-B models would start at $4,500, but only the base model was indicated to be priced under $4,000.
While the base model TM-B is more than $1,000 cheaper than other options, it comes with a number of compromises, such as a reduced maximum range of 60 miles, weak 5x power assist, coil fork suspension and only a standard ride mode. In comparison, higher-end TM-B options have 100-mile range, 10x power assist, air fork suspension, and a choice between sport and standard riding modes. Plus only the base model TM-B is being offered in all grey, meaning you won’t get the transparent shell that highlights the virtual drivetrain called DreamRide.
Although the starting price of the TM-B is more affordable than we expected, it is still a premium price for an e-bike. The TM-B base model is available for preorder with a $50 refundable deposit and will begin shipping in late 2026.
