California-based manufacturer Ride1Up has unveiled the Revv1 evo, a moped-style electric bike featuring a pioneering semi-solid-state battery designed to solve the longevity and reliability issues common in traditional lithium-ion packs. Priced at $2,395, the Revv1 evo is marketed as the first mainstream, accessible ebike in the United States to utilize this advanced chemistry. By replacing the flammable liquid electrolyte with a stable gel-like mixture, the battery offers significantly higher safety standards, improved performance in freezing temperatures, and a lifespan nearly triple that of conventional electric bike batteries.
The introduction of semi-solid-state technology marks a significant middle ground between standard lithium-ion and the fully solid-state batteries currently under development for the automotive industry. This chemistry provides enhanced chemical stability and fire resistance without the manufacturing hurdles that have prevented full solid-state cells from reaching mass production. Ride1Up reports that the Revv1 evo’s battery can withstand over 1,200 charge cycles before its capacity drops to 80%, compared to the 500 cycles typical of standard packs. For the average rider, this extends the battery’s functional life from approximately four years to nearly a decade.
Performance metrics for the new battery are equally notable. The system supports a full charge in just two hours, utilizing the semi-solid-state’s ability to manage heat more effectively than liquid-based cells, which often degrade rapidly under fast-charging conditions. In extreme cold, the battery reportedly maintains 70% of its capacity at temperatures as low as -20 °C, offering more predictable performance for winter commuters. On a single charge, the bike provides a range between 48 and 96.5 kilometers, depending on riding conditions and assist levels.
Built on the established Revv1 platform, the evo features a 750-W motor delivering 100 Nm of torque. It offers pedal-assist speeds up to 45 km/h and utilizes a specialized battery management system to monitor the health of the pack in real-time. The hardware includes DRT-spec suspension and Vee Huntsman all-terrain tires. However, the bike’s robust construction brings its total weight to approximately 41 kilograms, positioning it closer to a traditional moped than a lightweight bicycle. This makes it ideal for open-road commuting rather than urban environments requiring frequent lifting or indoor storage.
At a price point of $2,395, the Revv1 evo significantly undercuts other manufacturers exploring similar battery technology, such as the premium mountain bikes from Germany’s Nicolai. While other niche motorcycle-style ebikes have experimented with semi-solid cells, Ride1Up’s move signals that the supply chain for this technology is maturing enough for the broader consumer market. Pre-orders are currently open for the US market, with the first units expected to ship in August.
