High-Performance eMTB Fork: Elevate Your eSUB Hardtail Adventures

Engineered exclusively for eSUB Hardtail electric mountain bikes, this high-performance fork is built to handle the unique demands of powered off-road riding—combining robust strength, adaptive performance, and versatile design to elevate your e-mountain biking experience. Whether you’re tackling steep climbs, technical descents, or rugged trails, it delivers the power, control, and durability needed to match the torque and capability of your e-bike.​

With four adjustable travel options (80mm/100mm/120mm/130mm), this fork adapts seamlessly to every terrain and riding style. Opt for 130mm travel to crush rough descents and absorb heavy impacts, 100-120mm for balanced trail performance, or 80mm for lightweight efficiency on XC-style climbs—ensuring optimal shock absorption and control in every scenario. Paired with LOR/LO damper systems, it delivers responsive, consistent damping that minimizes bounce and maximizes traction, even when pushing your e-bike to its limits on technical terrain.​

Offering dual spring options—air or coil, both with preload adjusters—this fork lets you fully customize performance to match your weight, riding intensity, and terrain. The air spring delivers lightweight agility for efficient climbs and quick maneuvers, while the coil spring provides superior sensitivity and durability for heavy-duty use, ensuring optimal power transfer and trail contact. Compatible with up to 27.5"x2.6" (65-584) ETRTO tires, it accommodates wide, high-grip tires perfect for navigating loose dirt, rocky paths, and muddy trails—maximizing the off-road capability of your eSUB Hardtail.​

Crafted with a C58/1.5" to 1-1/8" tapered (CTS) alloy steerer (with an optional C68/1.5" to 1-1/8" tapered CTS alloy steerer) and 34mm STKM steel stanchions, this fork offers exceptional rigidity and strength to handle the increased weight and torque of e-bikes, without compromising on responsiveness. The 44mm offset optimizes wheel geometry, enhancing steering precision and stability at high speeds—critical for maintaining control when powering through technical sections. The alloy bottom case resists corrosion and wear, standing up to the rigors of frequent off-road use and ensuring long-lasting reliability.​

Equipped with a 15AH4-110 (15AH3-110 optional) axle and φ15-110 O.L.D design, it provides rock-solid wheel retention even during high-intensity rides and jarring impacts, while simplifying wheel installation and removal. The post-mount brake compatibility supports up to 203mm rotors via direct mount, delivering powerful, consistent stopping power to match the speed and weight of e-bikes—essential for safe navigation of steep descents and technical trails. Integrated short and long fender mounts add practicality, letting you attach fenders to keep mud and debris at bay in varying weather conditions.​

Whether you’re exploring backcountry trails, tackling technical singletracks, or embarking on long-distance e-bike adventures, this eSUB Hardtail fork delivers the performance, durability, and versatility you need. It’s the perfect upgrade to enhance your e-bike’s handling, comfort, and confidence—turning every off-road journey into a powerful, controlled, and exhilarating experience. Invest in a fork built to keep up with your e-bike’s power—dominate the trails and elevate your electric mountain biking journey today.
