San Diego-based electric bicycle manufacturer Ride1Up has made history launching the world's first electric bicycle with a semi-solid state battery, the Revv1 EVO, in which it claims to be one of the most significant technological shifts in e-bikes in years. The new battery offers major advantages such as safety, longevity, and thermal performance. It replaces the traditional lithium-ion cells used in nearly every e-bike with a gel-like material that offers improved stability, longevity and thermal stability. The battery can fully recharge in around two hours, which could potentially be a game-changer for riders in colder climates. It also retains around 70% capacity even at -20°C (-4°F), which could be a significant advantage for those riding in cold weather. The company's new bike uses a 52V 20Ah battery (roughly 1 kWh) and a high-power 9A charger, compared to the typical 2-3A charger typically paired with most e-vehicle.
