How Does an Electric Bicycle Work? (2025)

wired.com Stephanie Pearson 2025-12-03 09:00:00

An electric bicycle—it's a regular bicycle, but with a motor on it! There are enough moving pieces on these personal mobility vehicles to make buying one confusing. Even if you're pretty sure you know what an electric bicycle is—and that you're not, riding, say, an electric motorcycle from a dealership—the technology changes almost daily. Over the past 10 years, battery capacity has increased by around 50 percent, according to Joe Buckley, the e-mountain bike product manager at Specialized. In

techcrunch.com Sean O'Kane 2025-12-03 20:00:51

The mystery buyer of the former General Motors factory owned by Foxconn in Lordstown, Ohio is apparently SoftBank, according to Bloomberg News. SoftBank wants to use the factory to build AI servers as part of the Stargate data center project being spearheaded by the Japanese conglomerate, OpenAI, and Oracle. The report comes just a few days after Foxconn announced it had sold the factory, along with electric vehicle manufacturing equipment that was inside of it, to a buyer it only referred to a

Honda Is Giving Up on the All-Electric Dream

gizmodo.com Luc Olinga 2025-12-04 15:15:49

Honda just dealt a huge blow to the all-electric dream. In a stunning reversal, the Japanese auto giant has announced it is rethinking its electrification strategy, signaling that battery-electric vehicles (BEVs) are no longer the holy grail of its future. The move is a major setback for the EV industry, which is already reeling from the September 30 expiration of federal tax credits that made electric cars competitive with their gas-powered counterparts. For years, the auto industry, mesmerize

Linear sent me down a local-first rabbit hole

Foxconn sells former GM factory to mystery buyer after failing to make EVs

Will the UN finally broker a treaty to end plastic pollution?

To tackle what's been called the plastic "epidemic," the UN spun up a committee in 2022 tasked with brokering a legally binding global agreement. This ambitious treaty between UN member states was to address the full life cycle of plastics, from production to disposal: In short, define what counts as plastic pollution and curb the sorts of unchecked production that inevitably leads to it.
