The G198B Mountain Bike Electric Conversion Kit is designed for riders who need strong climbing power and long-distance durability. At its core is a robust gearless hub motor featuring a 198mm stator diameter and a 35mm magnet height. This brushless DC motor delivers 1000–1500W of power and supports 48V–52V systems, making it an ideal choice for building a high-performance mountain ebike. Its direct-drive structure offers smooth acceleration, powerful torque, and excellent reliability—well suited for steep trails and heavy-duty off-road use.
The kit pairs with a large-capacity downtube lithium battery, commonly used on mountain bikes. Ecoway Tech provides multiple battery options using 18650 or 21700 cells from LG, Samsung, Panasonic, or premium Chinese manufacturers. Some battery models are available with 5V mobile charging output and smart BMS protection. Several capacities have passed UL2271 and EN50604 certifications, ensuring enhanced safety and long-term performance.
For control, the G198B kit includes a fully waterproof controller matched to a 35A output to support the motor’s high-power characteristics. The controller can be integrated into the battery base for a clean and stable installation. It also supports Bluetooth app connectivity and optional IoT modules, enabling GPS tracking, anti-theft features, remote on/off, and navigation functions—ideal for both daily riders and fleet operators who value intelligent control.
The display options include standard LCD screens and full-color displays. Many models support multilingual interfaces and can be paired with Find My-style remote vehicle-locating features. For throttle selection, users can choose between thumb, half-twist, or full-twist throttles depending on riding preference.
Pedal assist options include both speed sensors and torque sensors. Riders who prefer natural pedaling feedback can choose the torque sensor, while speed sensors offer a classic pedelec experience. Brake options include electronic brake levers or simple brake sensors that allow bikes with high-end hydraulic brakes to retain their original braking setup.
Beyond the core components, Ecoway Tech can also supply front and rear lights, brake rotors, mechanical or hydraulic calipers, and other accessories based on customer requirements, making the kit suitable for complete OEM or DIY projects.
The G198B Mountain Bike Electric Conversion Kit is ideal for DIY mountain bike upgrades, high-power off-road ebikes, and electric tricycles that demand strong torque and long-lasting performance. Its combination of a powerful gearless motor, intelligent controls, and high-capacity battery options makes it one of the most reliable choices for building a rugged, high-performance ebike.
