architecture-design · 2026-07-03

Halfbike Pro, the latest model from the Bulgarian company Kolelinia Ltd., has officially launched after a decade of development. This unique three-wheeled device allows riders to stand while mimicking movements similar to cycling, running, and skiing, effectively targeting multiple muscle groups. The design includes a redesigned frame, a larger 20-inch front wheel, and a V-shaped handlebar for added stability. It also folds flat for convenient transportation and is available in Aura and Stealth finishes. The original Halfbike remains in production. Established in Sofia in 2014, the company previously secured over $1 million through a successful Kickstarter campaign.
