## Rivian's bold e-bike vision
Rivian spinoff Also generated massive hype with the TM-B, an ambitious e-bike featuring a software-controlled pedal-by-wire system and removable battery design.
## Delivery delays spur backlash
Deliveries were originally promised for spring 2026 and pushed to summer. With fall approaching and zero bikes shipped, frustrated reservation holders took to Reddit.
## AI boom squeezes chip supply
Product manager Saul Leiken posted an apology, blaming shortages of circuit boards and integrated circuits driven by demand from the AI boom.
## Regulatory battery roadblocks
The high-capacity battery's 240W power delivery exceeds current safety guidelines, forcing Also to work with standards groups on new safety protocols.
## Complex pedal-by-wire system
The DreamRide drivetrain eliminates mechanical connections between pedaling and wheel movement. The high-precision system slowed production ramp-up significantly.
## Prioritizing quality over speed
Also admitted it failed to communicate effectively about delays, but stood by its decision to hold back shipments rather than compromise on standards.

> As we ramp production we can relax standards against an original timeline or we can hold to a high standard and face potential delays.
## Key takeaway

Cutting-edge hardware features often come with steep manufacturing and regulatory hurdles that push back delivery timelines.
