Rivian’s first e-bike is unlike anything you’ve ever seen

Rivian’s micromobility spinoff Also has just taken the wraps off its TM-B e-bike, TM-Q pedal-assisted electric quad bike, and Alpha Wave helmet that represents “a breakthrough in rider safety and connectivity.” 

The TM-B (aka Transcendent Mobility – Bike) with its 24 x 2.6-inch wheels and integrated front- and rear-lighting looks and functions like nothing else on the market. It features a new pedal-by-wire drivetrain called “DreamRide” developed in-house. The rider pedals a generator, which replenishes the battery, while a separate software-driven traction motor drives the rear wheel via a Gates Carbon belt. 

The removable battery — available in either 538Wh or 808Wh packs, offering up 100 miles of range — features two USB-C ports. The batteries can be charged over USB-C at 240W, going from zero to full in two hours and 20 minutes or three hours and 45 minutes, respectively. They can also act as a portable power bank for your gadgets. An E Ink display shows the battery’s current charge.

As a Class 3 e-bike, it has a pedal-assisted top speed of 28mph (45kph). It also features a throttle good for 20mph where regulations allow, and an astounding 180Nm of torque on tap — enough to flatten steep hills and make quick starts off the line when carrying heavy loads. Hydraulic disc brakes help bring everything to a controlled stop, while regenerative braking could extend range by an estimated 25 percent.

The top frame of the TM-B is modular by design, so the bike can be transformed without tools into a cargo hauler, kid carrier, or cruiser with a bench seat. The seat post is unlocked via a quick swipe from the 5-inch circular touchscreen console. An inverted front fork suspension and air shock will help soak up bumps for riders ranging from 4 feet 11 inches to 6 feet 8 inches.

There’s also plenty of security baked in that automatically activates and deactivates when the rider is nearby. It locks the battery, back wheel, and frame, with tamper alerts and bike location provided in real time.

A $4,500 launch edition TM-B can be preordered now with delivery slated for spring 2026. A $4,000 base edition is scheduled for sometime later in 2026.

Also also unveiled its Alpha Wave helmet. “It incorporates Release Layer System (RLS), a technology that offers a step-change in rotational impact protection,” says Also, which certainly sounds impressive. It also features integrated lights and a four-speaker, wind-shielded internal audio system with two noise-canceling mics. The helmet integrates with the TM-B’s console, where music, calls, and podcasts can be controlled on the bike.

Lastly, Also’s TM-Q is the TM-B extended to a pedal-assisted electric four-wheeler to carry heavier loads. Also says it’ll be “bike lane compliant,” so it can be used for last-mile deliveries in congested cities. It’ll be sold in both commercial and consumer variants, the latter for ridding around gated communities.

The TM-B aesthetic is certainly divisive — I love it, but I was a big fan of Cake’s utilitarian designs before bankruptcy. It’s a lot to take in and certainly needs thorough testing to draw any final conclusion. But it’s good to see a fresh, deep-pocketed face breathing new life into e-bikes when entrenched players and boutique brands are struggling to stay afloat.

“Our vision is to bring together the latest technology with fun, thoughtful design to create small EVs that inspire people to adopt these more efficient modes,” said Chris Yu, president of Also. “This launch has been years in the making and it is just the beginning of a broader platform we are building that we believe will catalyze adoption globally.”
