ALSO TM‑B: Rivian spinoff rethinks the e‑bike with software‑defined pedaling

Rivian’s micromobility spinoff Also has unveiled its first e‑bike, the TM‑B — a modular, tech‑forward design aimed at commuting, trail rides and family/cargo hauling. The standout feature is “DreamRide”, a software‑defined pedaling system that decouples the pedals from the rear wheel to tune ride feel in software.

Key features at a glance

• Software‑defined pedaling (DreamRide): Pedal input feeds a generator that powers the battery; assistance and “gearing” are controlled in software. A limp mode lets you pedal enough power to reach a charger if the pack is depleted.
• Battery & range: Removable USB‑C battery options with up to 60 miles (standard) or 100 miles (large). Packs can double as high‑capacity power banks off the bike.
• Speed: Throttle up to 20 mph; up to 28 mph with pedal assist (local regulations apply). Regenerative braking helps recapture energy.
• Modularity: One frame adapts to multiple rider sizes via different saddles, including a bench seat and a rear cargo rack rated around 35 kg. Seats swap tool‑free via a latch controlled from the bike’s touchscreen.
• Portal display & app: A 5‑inch touchscreen provides navigation, music and calling, with companion‑app integration. Handlebar controls are customizable for volume, calls and UI.
• Security: Built‑in system auto‑locks frame and rear wheel when you walk away; supports proof‑of‑delivery style photo capture and remote features.

Also TM‑Q pedal‑assist quads (preview)

• Family TM‑Q: A compact, bike‑lane‑friendly alternative to cars that can still haul significant loads.
• Commercial TM‑Q: A larger quad aimed at deliveries; Also is collaborating with Amazon on Prime‑branded fleets.
• Timing & pricing: Not yet announced.

Why it matters

• Ride feel via software: DreamRide enables tailored assistance profiles and could reduce mechanical wear versus chains/gears.
• Urban logistics: Bike‑lane‑sized quads may help cut congestion and emissions for last‑mile delivery.
• Auto‑grade tech: The Portal display, app integration and security reflect Rivian’s tech‑first approach in a smaller form factor.

Discussion: Would you trade a traditional chain for software‑defined pedaling and a built‑in nav/security stack at $4,500—or stick with a simpler setup?
