Rivian has since discontinued its “micromobility business”. Individual startups Also said earlier this year, there was a lot of speculation about what kind of vehicle the company was working on. Now, also showcasing its first products: a lineup of e-bikes and two pedal-assist electric quads.
The TM-B e-bike is an attempt at a do-it-all e-bike that can adapt to a variety of daily commutes, trail riding or kid and cargo transportation. It sports a modular frame that can also accommodate a bench seat or a rear cargo rack that supports up to 35kg.

Different seats can be easily swapped without additional tools. Instead, a button on the bike’s touchscreen display controls a latching mechanism that releases the seat. It only comes in one frame size, but it also says it should be able to accommodate “multiple body shapes” for different seat sizes and styles.

The removable USB-C battery comes in two sizes: standard, which can power up to 60 miles of riding, and large, which tops out at 100 miles of range. When you’re not riding, the batteries can also be used as a large external battery pack.
In terms of power, the TM-B tops out at 20MPH on the throttle, though the bike can reach speeds of up to 28MPH with extra pedaling. It’s also taking an interesting approach to its drive system, with a setup it labels “DreamRide.” Instead of a mechanical connection between the bike’s rear wheel and the pedals, the TM-B uses “software-defined pedaling.”

In practice, this means that you pedaling is actually feeding the generator that powers the bike’s battery instead of pushing you straight ahead. However, a representative also told me that the bike also has a “limp mode” for running out of juice so riders don’t get stuck. In this situation, pedaling will give the bike enough juice to hopefully get you to a place where you can recharge.
The TM-B also envisions a number of scenarios, many of which involve carrying a lot of cargo.

Software-controlled pedaling probably won’t appeal to purists, but say it enables a more customizable riding experience. While in Auto mode, the bike will adapt to the speed you’re pedaling, though you can push the throttle to get a boost. There’s also a manual mode that lets you select a “gear” (these are also software-controlled).

It also uses regenerative braking, so tapping the brakes helps recharge the battery. On my short test ride though I found I didn’t need to use the brakes much, as the bike decelerated very quickly when I stopped pedaling, similar to taking your foot off the accelerator in an EV.
Also display apps and portals.

Given the bike’s roots in the Rivian, it’s no surprise that there are other tech-enabled features, including a 5-inch touchscreen display, called “Portal,” which supports navigation, music playback and calling features via an accompanying app. There’s also a built-in safety system that automatically locks the frame and rear wheels when you walk away. On the handlebars, there are customizable controls that can be used to adjust volume and music playback, answer calls, or navigate through displays.

Also selling the TM-B in three configurations. First to ship next spring will be the $4,500 TM-B Limited Launch Edition, which features up to 100 miles of range, support for Standard and Sport ride modes, and transparent purple accents. The $4,500 TM-B Performance has the same features as the limited edition model, but a slightly different color scheme and will be available in the “first half” of 2026. Finally, there’s a base-level TM-B model with a range of up to 60 miles that only comes with standard ride mode. Also didn’t announce an exact price, but said it will cost less than $4,000 when it ships “after 2026.”
Pre-orders for the launch edition are open now And two other bikes are available to reserve with a $50 deposit. The bikes will be showcased in Rivian showrooms later this year,

The company previewed two electric, pedal-assist quads it’s calling TM-Q. The small quad is apparently meant for “families and individuals looking for a safe, compact alternative to a vehicle” that can still carry “significant loads”. The larger TM-Q, on the other hand, is meant for commercial distribution.
It has also partnered with Amazon to build a fleet of such vehicles that can be used by delivery drivers. Both quads are intended to use the bike lane, also according.
