You approach the KHS Vitamin C Hybrid Fitness Bike and immediately sense it’s built for those who want more than a basic commute- a bike that blends everyday practicality with road-bike speed. Its frame is 6061-series aluminum, custom-formed and double-butted, giving the bike a solid but light foundation. 

Looking closer, the fork is carbon (with aluminum steerer), giving just enough compliance to smooth small road bumps while keeping weight down- a subtle but important touch that makes long rides easier. 

Mount the 700c wheels- shod with 700×32c “Kenda Kwick Roller” tires with anti-puncture protection- and the ride feels confident: fast enough for light road work, plus stable and cushioned enough for urban streets or rougher pavement. 

Shift through the 2×9 drivetrain: dual-ring compact crankset (50/34T) up front, 9-speed cassette at the back, front derailleur from Microshift, rear from Shimano Sora. It’s not race-car quick, but it’s smooth, predictable, and ideal whether you’re climbing hills, accelerating from a stoplight, or cruising along. 

When you grab the brakes, you feel the firm, confident bite of hydraulic disc brakes (Bengal Aries 3, 160 mm rotors)- reliable and consistent braking, even in wet or unpredictable Vancouver weather. 

Overall, the 2025 KHS Vitamin C feels like a practical-performance hybrid: nimble and efficient enough for fitness rides or commuting, yet comfortable and stable enough for daily urban use. It doesn’t scream “race bike,” but it doesn’t feel like a clunky hybrid either. It’s a well-rounded tool that quietly tells you: “I’ll get you where you want to go- smoothly, reliably, and with a bit of edge.”
