Back-to-school season often means shopping for backpacks, notebooks, and maybe even a new ride. For a growing number of families, that ride is an electric bike.

And I’m all for it. Giving teenagers the freedom to get themselves to school, sports practice, or a friend’s house without needing a car is one of the best things e-bikes can offer.

Archer Aviation is buying three of Boeing’s aerospace subsidiaries: autonomous air-taxi developer Wisk Aero, military drone maker Insitu, and airspace-software firm SkyGrid. The deal also hands Boeing a stake in Archer.

Investors loved it. Archer (ACHR) stock jumped more than 20% on Monday, and the acquisition instantly turns a pre-revenue eVTOL startup into a company with a profitable defense business behind it.

It could accelerate Archer’s eVTOL plans.

SpaceX confirmed it will power Terafab, its $16.8 billion chip megafactory in Texas, with its own natural gas power plants and “very large battery arrays.” Tesla solar isn’t in the plan.

Chinese autonomy experts Pony.ai are planning to put 1,000 autonomous electric commercial trucks to work by 2027, but it’s the company’s plans to put 100,000 self-driving trucks on the road by 2030 that’s making headlines.

Zero Motorcycles has launched a new incentive program that offers cash back to newly licensed riders who purchase one of the company’s electric motorcycles or scooters. It’s an interesting way to encourage new motorcyclists to skip internal combustion and go electric from day one.
