Rivian is taking its electric brilliance off four wheels and onto two.

Its new offshoot, Also, has unveiled the TM-B, which is a clever modular e-bike that feels more like a piece of precision engineering than a simple commuter.

At its core is DreamRide, a propulsion system that flips convention on its head. Instead of the pedals driving the wheels, they charge the battery as you ride, turning effort into energy.

Fast charging pushes the battery to 80 percent in under two hours, while the top-tier model promises 100 miles of range and a zippy 28-mph top speed.

What really stands out is versatility.

You don’t need multiple bikes for multiple activities.

The TM-B’s interchangeable top frame lets riders swap between cargo mode, solo cruiser, or full bench setup in seconds. It’s part utility, part play, and very attractive for those that want one bike that can do it all.

This is where Rivian’s DNA shines through. Their deep EV expertise brings smarter batteries, faster charging, and rock-solid software integration.

Even the onboard display feels more connected than most e-bikes on the market.

AS Rivian’s CEO has mentioned: Large electric SUVs and trucks address only a small part of the market. More mobility devices like e-bikes and scooters are essential.
