A number of years in the past, as a skunkworks crew of engineers inside Rivian got down to develop an electrical micromobility car, one query loomed: “What will we construct in-house?” Rivian founder and CEO RJ Scaringe stated in an interview recounting the early days of Also, which spun out of Rivian earlier this yr.
“We realized the one method to do that effectively is to construct all the pieces,” stated Scaringe, who sits on Additionally’s board.
The consequence, which was revealed Wednesday at an occasion in Oakland, is a pedal-assist electrical bike referred to as the TM-B that’s greater than only a bike, in accordance with Scaringe and Additionally president Chris Yu. “It is a entire platform of merchandise we’re going to construct within the microspace,” Scaringe stated. And Scaringe wasn’t kidding. Throughout the Wednesday occasion, Additionally revealed two quad automobiles as effectively, considered one of which can be supplied to Amazon.
At a passing look, this “greater than a motorbike” appears to be like like a motorbike, albeit a sleekly designed one which has just a few hidden-in-plain-sight options. However Yu contends that what lies beneath the floor is what makes the TM-B particular and compelling sufficient to interrupt right into a crowded e-bike market.
The TM-B will are available a number of trims, together with a launch version, and efficiency and base variations.
The launch version has similar specs with the efficiency trim, together with a battery that has an estimated 100-mile vary, 10 assistive ranges, air shocks and air fork for the suspension, and two experience modes, together with “sport” that zips the rider down the street. The launch version, which prices $4,500, is sprinkled with particular “launch” colours of a purple ube and blue and can come to market this spring.
The efficiency trim, which additionally retails at $4,500, is predicted to come back to market within the first half of 2026. The bottom model, which has a battery with as much as 60 miles of vary, 5 assistive ranges, an air shock and coil fork for the suspension, and one normal experience mode, is predicted to value lower than $4,000 when it hits the market within the second half of subsequent yr, in accordance with Yu.

The entire bikes are outfitted with entrance and rear LED lighting with built-in flip alerts and have a prime pace of 20 miles per hour. Biomotion design illuminates rider’s legs as they pedal on the TM-B, which has 24-inch wheels. The TM-B may also be outfitted with all-terrain tires, pedals, and a path experience mode that offers riders extra guide management over the experience.
The battery is detachable and comes with USB-C quick charging as much as 240 watts that lets customers energy up gadgets.

There’s an built-in safety function to maintain the battery and the bike protected as effectively. The safety system is engaged as soon as the rider walks away from the bike and routinely locks the battery, wheels, and body. Whether it is tampered with, the rider will obtain an alert through the Additionally app and the bike will emit a loud honking sound.
As a facet notice: That honking sound may be deployed by the rider as they navigate metropolis streets.
“You get a push notification within the unlucky case when it begins shifting away as a result of we now have LTE and GPS, and we now have an actual time, location,” Yu stated onstage Wednesday. In a worse-case state of affairs, if the bike is bodily picked up and positioned in a car, the e-bike proprietor can remotely disable it.
“You’ll be able to brick it,” Yu stated. “And that is key, as a result of since we personal each board, every bit of software program, each a part of the bike, that signifies that no a part of that is usable.”
The tech contained in the TM-B

All the pieces was developed by the Additionally and Rivian crew, together with the detachable battery pack, energy electronics, software program, firmware, and a pedal-by-wire propulsion system that has no mechanical connection between a rider’s pedaling and the motion of the bike. Notably, the system permits for regenerative braking, which implies energy is distributed again into the battery.
Even the instruments to construct these parts have been designed right here, in accordance with Additionally CTO Jonathan Corridor, who spoke to TechCrunch forward of the occasion.
The entire trims have a number of standout design and practical options, together with a central touchscreen show that’s built-in between the handlebars. Maybe essentially the most fascinating is the modular prime body that permits the consumer to alter from a solo, bench, or utility cargo setup inside just a few seconds.

The usual solo seat comes with two water bottle cages. The utility setup has an built-in rear rack and one water bottle cage mount and may carry about extra 77 kilos of cargo. Is also providing a 3rd bench choice as effectively. And all of those may be swapped out in just a few seconds and with out instruments.
Notably, the software program of every setup is aligned with that consumer and syncs with the central touchscreen.
Like over at Rivian, Additionally’s software program is a central determine of its electrical bike and can proceed for use to roll out new options, Yu instructed TechCrunch. For example, software program is used to offer correct navigation and ETA to the rider by tightly integrating with the movement and pace of the ebike.
“As a result of we all know a lot about your expertise, we all know what help stage you’re in, we all know what experience load you’re in, we all know the common pace that you just’ve been going — we may give you a extremely, actually exact ETA,” Yu stated whereas exhibiting off the TM-B onstage. “It sounds easy, however you’re utilizing this as a car to get someplace. It form of issues to know while you’re going to get there.”
The helmet

The corporate additionally developed a helmet in-house referred to as the Alpha Wave Helmet that makes use of a newly developed expertise to enhance rotational impression safety and a redesigned strap so the consumer can tighten it — no snapping — with one hand.
The helmet has quite a few tech options past defending your mind, together with built-in lights and an audio system with 4 wind-shielded audio system and two noise-canceling microphones. The helmet syncs with the bike’s central “portal” touchscreen or the rider’s telephone to allow them to take heed to music, take calls, and obtain turn-by-turn navigation.
