The YKB-R04 is a premium flat handle road bike engineered to bridge the gap between the speed and lightness of traditional road bikes and the stability and maneuverability of mountain bikes. Designed for riders seeking adaptability across diverse terrains, this model redefines multi-purpose cycling with its thoughtful combination of high-performance components and durable construction. Whether navigating busy city streets, exploring scenic country roads, or tackling light off-road trails, the YKB-R04 delivers a balanced riding experience that caters to both daily commuters and leisure cyclists. Its straight handlebar design enhances comfort during long rides, while precision engineering ensures efficiency and control in every scenario.
At the core of the YKB-R04’s exceptional performance is its 6061 aluminum alloy frame—a material renowned for its optimal strength-to-weight ratio. This high-grade aluminum alloy undergoes advanced manufacturing processes to achieve a frame that is both lightweight (critical for long-distance riding and climbing) and remarkably rugged. Unlike heavier steel frames, the 6061 aluminum construction reduces overall bike weight without compromising durability, making it resistant to corrosion, impacts, and daily wear. This material choice ensures the YKB-R04 can withstand the demands of urban commuting, occasional off-road use, and frequent long rides, maintaining structural integrity for years of reliable performance.
The 6061 aluminum alloy frame is the foundation of the YKB-R04’s appeal. Weighing significantly less than traditional steel frames, it minimizes rider fatigue during extended journeys, whether commuting to work or embarking on weekend adventures. Simultaneously, its high tensile strength ensures the bike can handle rough patches, curbs, and light off-road obstacles without bending or warping.
Equipped with a dry 10-speed chain drive system, the YKB-R04 offers an extensive range of gear ratios to adapt to varying terrains. From flat urban roads requiring high-speed cruising to steep inclines demanding more torque, riders can seamlessly shift gears to match their pace and effort. This versatility eliminates the need for multiple bikes for different scenarios, making the YKB-R04 a cost-effective all-in-one solution.
The integrated aluminum alloy front fork enhances the bike’s rigidity, providing superior stability during high-speed rides and precise handling on uneven surfaces. This design reduces vibration transfer from the road to the handlebars, ensuring a smoother experience even on gravel paths or bumpy city streets.
Safety is paramount, and the YKB-R04 delivers with Shimano MT200 hydraulic disc brakes. These brakes offer powerful stopping force and instant response, even in wet or muddy conditions—critical for urban commuting where sudden stops are common. Unlike rim brakes, hydraulic disc brakes maintain consistent performance regardless of weather, reducing the risk of skidding and ensuring reliable control.
The transmission system combines Shimano M2010 shifters, FD-T500 front derailleur, and RD370d rear derailleur for precise, smooth gear changes. Paired with the Sunrace MTH2099 9s Cassette Index Freewheel, this setup ensures durability and consistent performance, even with frequent use. Riders will appreciate the seamless transitions between gears, whether accelerating on straightaways or navigating tight turns.
The YKB-R04 excels in city environments, thanks to its lightweight 6061 aluminum frame and efficient 10-speed drive system. It glides through traffic with ease, while the flat handlebar provides a comfortable upright riding position—reducing strain on the back and shoulders during daily commutes. The Shimano MT200 brakes ensure quick stops at intersections, making it a safe choice for busy streets.
Weekend riders will love exploring parks, coastal roads, or countryside paths on the YKB-R04. Its balanced design offers both speed for covering distance and stability for enjoying scenic routes. The comfortable handlebar and smooth transmission make long rides enjoyable, while the durable frame handles occasional detours onto gravel or dirt tracks.
Though primarily a road-focused bike, the YKB-R04’s rugged frame and stable front fork allow it to tackle light off-road terrain. Whether exploring forest trails or unpaved backroads, it maintains control and comfort, making it ideal for riders who want to venture beyond city limits without investing in a full mountain bike.
For cyclists planning multi-day trips, the YKB-R04’s lightweight construction reduces fatigue, while its efficient drivetrain maximizes energy usage. The reliable braking system and durable components ensure it can handle the demands of extended journeys, from coastal highways to hilly countryside routes.
Yes, the YKB-R04 is beginner-friendly. Its flat handlebar design offers intuitive control, and the 10-speed drive system is easy to adjust, even for new riders. The stable frame and responsive brakes also build confidence, making it a great choice for those new to cycling.
The YKB-R04’s 6061 aluminum alloy frame keeps its total weight relatively low (exact weight varies slightly by size, but typically ranges from 10-12kg), ensuring it’s easy to carry up stairs or load onto bike racks.
With regular use, the Shimano M2010+FD-T500+RD370d transmission and Sunrace MTH2099 9s Cassette should be serviced every 500-800km. This includes cleaning the chain, lubricating moving parts, and adjusting derailleurs for optimal performance.
Yes, the bike is compatible with common accessories like fenders, racks, and lights—ideal for urban commuters needing to carry bags or ride in low-light conditions.
