- Rivian-backed startup Also unveiled the TM-B, a modular electric bike that adapts for multiple uses.
- The TM-B uses a pedal-by-wire system called DreamRide that replaces the traditional chain drive.
- Its Rivian-grade battery doubles as a power bank and can charge other devices via USB-C.
- Launch is expected in 2026 with a starting price of around 4,000 dollars.
A California startup called Also has introduced an e-bike that could completely change how people move through cities. Backed by electric vehicle maker Rivian, the new model, named TM-B, is built with a modular system that lets riders transform it from a cargo carrier to a trail-ready bike in seconds.
The Palo Alto-based company calls it the Transcendent Mobility Bike, and it is designed to make electric mobility simple, flexible, and fun. Unlike typical e-bikes, the TM-B is built from the ground up using the same engineering principles that power Rivian’s advanced electric vehicles.
Built for Change
The TM-B’s most striking feature is its modular design. The central body of the bike can accept different “top frames” that change how it functions. Riders can switch from a standard saddle setup to a family-style cargo seat or even a low scooter-style bench. All of this can be done at the press of a button on the digital display.
Each configuration connects securely through an electrical locking system, similar to how snowboard bindings clip in. Every attachment is also powered, meaning rear lights and other accessories automatically sync with the bike once connected. This kind of flexibility means one e-bike can serve as a commuter vehicle, family hauler, or adventure machine—all in one package.
The Future of Pedal Power
What sets the TM-B apart technically is its pedal-by-wire system called DreamRide. Instead of using a traditional chain or belt to transfer power, the system relies on sensors and smart software. These sensors measure the rider’s effort, the road incline, and the desired speed to deliver a perfectly balanced level of assistance.
The bike offers ten assistance levels, and riders can even choose digital gear mapping that mimics real gear shifts for trail riding. With pedal assist up to 28 miles per hour, the TM-B qualifies as a Class 3 e-bike in the United States. The settings can also be adjusted to meet local laws when it launches in other countries.
Chris Yu, the founder and president of Also, says DreamRide was created to make e-bikes easier for everyone. He explains that many new riders struggle with gear changes and assist levels. DreamRide handles all of this automatically, learning from the rider’s input to deliver a natural experience. It also features regenerative braking that feeds power back into the removable battery.
Power That Goes Beyond the Road
The TM-B’s battery system deserves special mention. It uses Rivian-grade cells and doubles as a portable power source. With two USB-C ports offering up to 240 watts of output, users can charge laptops, cameras, or camping gear while off-grid. This makes the TM-B as useful at a campsite as it is on the city streets.
The e-bike’s Portal display gives riders full control through both touchscreen and handlebar buttons. It manages everything from ride modes to media playback. The system pairs with a smartphone, which also acts as a smart key. The TM-B locks automatically when the rider walks away and unlocks when they return. In case of theft, the bike can be completely disabled remotely, turning the electronics into dead weight and making the bike useless to resell.
Expanding the Ecosystem
Also is not stopping with bikes. The company has already adapted the TM platform for four-wheel vehicles known as TM-Qs. These compact quads are designed for stability and can carry heavy cargo or multiple passengers, making them ideal for family use or last-mile deliveries.
Alongside the bike, Also has introduced the Alpha Wave Helmet, featuring new safety technology called Release Layer System (RLS). The system provides better rotational impact protection than traditional designs and comes with built-in lights, microphones, and speakers. The helmet even supports voice commands and hands-free calling.
High-End Tech at a Reasonable Price
Despite its impressive technology, Also plans to sell the TM-B starting at around 4,000 dollars. That is significantly lower than other e-bikes offering similar performance. With 180 newton-meters of torque, advanced suspension, and a range of up to 100 miles, the TM-B matches or beats models that often cost three times more.
Also credits this price advantage to Rivian’s influence. By building and designing everything in-house, the company avoids relying on outside suppliers, keeping costs lower without sacrificing quality.
The first TM-B units are expected to appear in Rivian stores and select retail outlets by spring 2026. Also will launch a variety of accessories and configurations, from cargo racks to custom luggage, alongside the Alpha Wave helmet.
