The Freshly Charged Take


Can the Kingsong F18 Become The King Of EUCs Again?

After years of rocky launches, KingSong has built an electric unicycle that can finally trade punches with Begode, LeaperKim, and InMotion. The F18 pairs a 5,000W (nominal) motor and a 2,664Wh Samsung 50S pack with 100mm of toolless, adjustable quad suspension, and it stopped from 20 mph in just 12 feet in the team's first official EUC brake test. Jimmy and Andrew loved the carving, speakers, and app, but they also hit snags with restrictive stock pads, a loose trolley handle, and exposed lighting, so we break down who should buy it and whether KingSong has earned its crown back.
