Major e-bike company set to launch semi-solid-state battery electric bicycles

Late last year, I had the chance to check out the world’s first semi-solid-state batteries designed for electric bicycles. At EICMA 2025, I visited T&D, an electric mobility company that was spun out of e-bike component maker Bafang (and founded by the same co-founder of Bafang, Sunny He). There I saw the first production-destined semi-solid-state e-bike batteries.

At the time, it was a big secret which company would be the first to put them into e-bikes and get those new batteries on the road. But now we’ve finally learned who will claim the title: Giant.

Giant Manufacturing is preparing to unveil what it claims will be the industry’s first electric bike powered by a semi-solid-state battery, marking a potentially major step forward in e-bike battery technology.

The announcement positions the upcoming model as a “smart power bike” built around what Giant calls an industry-leading semi-solid battery system. While full details remain under wraps, the company is clearly aiming to differentiate itself in a market where battery innovation has largely plateaued around conventional lithium-ion chemistries.
