Rivian’s Smart E-Bike Adapts Perfectly to Your Ride

The new Rivian-spinoff Also TM-B electric bike represents a bold leap forward in personal transportation, blending automotive-inspired technology with a highly adaptable riding experience. When the company first revealed its debut model, the reaction was decidedly mixed. The unconventional design certainly turns heads, while its heavy reliance on sophisticated software raised immediate questions about reliability and complexity. For cycling traditionalists who value mechanical simplicity, this e-bike appears to be anything but straightforward.

A review of the technical specifications only deepened initial skepticism. The TM-B incorporates a zonal architecture, series hybrid powertrain, and a completely novel pedal-by-wire system, features completely alien to conventional bicycles. This isn’t just an incremental improvement; it’s a fundamental reimagining of what a bicycle can be. With such ambitious engineering, the obvious question emerges: exactly which riders is this high-tech machine intended for?

With a starting price of $4,500, the TM-B positions itself firmly in the premium e-bike market. This becomes particularly striking when you consider that America’s bestselling e-bikes are often folding, fat-tire models available for under $1,000. Also clearly isn’t targeting the mass market, instead focusing on early adopters willing to invest significantly in cutting-edge cycling technology.

However, any lingering doubts quickly evaporate the moment you begin to pedal. The riding experience is genuinely transformative, especially in urban environments. Navigating Manhattan’s 10th Avenue, the TM-B’s “10x” assist multiplier provides enough power to not only match but frequently surpass surrounding car traffic. This capability isn’t about speed for its own sake, it’s about creating a safer, more confident riding experience in challenging conditions.

The pedal-by-wire system eliminates traditional mechanical connections between the pedals and wheels. Instead, torque sensors translate your pedaling effort into electrical signals that drive a traction motor within the distinctive square-shaped “Dream Ride” powertrain. An additional motor in the rear hub provides supplementary power, creating a remarkably smooth and responsive acceleration profile.

The bike’s true genius lies in its software-driven adaptability. Riders can instantly switch between riding modes with a simple button press. Auto mode stands out for its intelligence, select your preferred pedaling rhythm and the system automatically adjusts motor output to maintain that cadence whether you’re climbing hills, descending, or riding on flat terrain. The system responds in real time, creating an effortlessly consistent riding experience.

For those who prefer more traditional feedback, manual trail mode simulates the sensation of shifting through gears despite the absence of physical gears or derailleurs. Using a handlebar-mounted switch, riders can click through virtual gear settings to find their ideal pedaling resistance. The transition between resistance levels feels intuitive and gradual, allowing you to find that perfect balance between effort and assistance.

Product director Saul Leiken emphasized that the TM-B’s software-based system creates “no mechanical ceiling,” enabling the bike to conquer exceptionally steep inclines while maintaining a steady cadence around 70 RPM. He described effortless ascents of San Francisco’s notorious 30% grade hills, a feat that would challenge many traditional e-bikes.

Regarding reliability concerns, Leiken clarified that the core drivetrain logic operates entirely locally, ensuring the bike remains fully functional even during cloud service outages. While certain features like anti-theft protection and firmware updates do require connectivity, the riding experience remains uncompromised regardless of network status.

The 5-inch circular touchscreen display provides one of the most sophisticated interfaces currently available on any e-bike. Unlike the basic LCD screens common on budget models, the Portal screen offers vibrant graphics with intuitive access to battery status, navigation, and ride mode information. The interface strikes an excellent balance between providing comprehensive data and avoiding information overload.

Modularity extends to the physical design through an interchangeable top frame system. Without requiring tools, riders can swap between different seat posts to reconfigure the TM-B as a cargo carrier, child transporter, or comfortable cruiser with bench seating. While this flexibility is impressive, the additional cost of accessory seats may give pause to buyers already investing significantly in the base bicycle.

The premium pricing remains the most significant barrier to widespread adoption. At $4,500 for the launch edition, the TM-B competes in a rarefied segment of the e-bike market. While the connection to Rivian’s design language and brand identity may attract certain buyers, the unconventional styling and advanced technology likely confine it to niche appeal.

For those with the budget and desire for the most technologically advanced e-bike available, the TM-B delivers an unparalleled riding experience. The combination of sophisticated software, powerful performance, and thoughtful design elements creates a product that genuinely pushes the boundaries of what electric bicycles can achieve.
