Revolutionary E-Bike Battery Promises Fireproof Charging

The German e-bike manufacturer Lemmo has unveiled its first cargo bike, the Lemmo 3, distinguished by its innovative semi-solid state battery technology. This advancement significantly enhances safety by reducing the risk of thermal runaway, a common issue with traditional lithium-ion batteries. The new battery chemistry also provides improved energy density, leading to a longer lifespan and extended range.

The Lemmo 3 is engineered to deliver up to 180 kilometers (110 miles) on a single charge, thanks to its 960Wh semi-solid state battery. This battery is claimed to be 20% smaller and lighter while offering 30% greater longevity. Additionally, the removable battery can function as a power source for AC appliances up to 1000W and USB-C devices up to 66W.

Marketed as an eSUV, the Lemmo 3 is a robust, full-suspension cargo bike built for utility rather than off-road adventures. It has a total load capacity of 200kg, with 80kg supported on the rear rack and 20kg on the front rack. Compatibility with MIK HD accessories further enhances its practicality, allowing for easy attachment of child seats, bags, and boxes.

The bike features a rear-hub motor with varying power outputs depending on the region (750W in the US, 250W in Europe). It includes an AI-driven adaptive system that optimizes gear selection in real-time for a seamless ride. The Lemmo 3 is also equipped with integrated lighting, a 3.5-inch touchscreen, GPS tracking, and hydraulic brakes that engage both wheels simultaneously. Pre-orders are open via Kickstarter for the EU, UK, US, and Canada, with deliveries anticipated in April 2027.
