Following its successful acquisition of the classic German brand Urban Drivestyle (UD) and its international expansion, Taiwanese electric scooter brand SEic announced today (March 24th) a deep cross-industry technological collaboration with Delta Electronics. The two companies plan to publicly showcase the "UDX concept scooter," equipped with Delta's latest Gen2 mid-drive motor system, for the first time at the upcoming 2026 Taipei International Cycle Show.
This next-generation superbike, boasting an astonishing 100Nm of torque and a coaxial innovative patent, not only extends SEic's urban commuting aesthetics to off-road mountains and forests, but also symbolizes Taiwanese brands setting a new technological benchmark in the global field of smart micro-mobility.
Hidden, ferocious power: Delta Gen2 coaxial mid-drive motor
In the past, SEic's classic models mostly used rear-wheel hub motor systems. This design, with its rearward center of gravity, offers stability, smoothness, and low maintenance costs, making it ideal for urban commuting and daily leisure. However, to satisfy hardcore enthusiasts' desire for off-roading, hill climbing, and ultimate speed, the UDX concept car features a comprehensively upgraded powertrain.
The UDX concept car incorporates Delta's latest coaxial innovative motor (Mid-Drive Gen2). The biggest highlight of this mid-drive motor system is its peak torque output of up to 100Nm (compared to about 40-50Nm for commercially available electric vehicles), giving the vehicle extremely strong starting and climbing thrust.
Meanwhile, Delta has used its patented precision technology to integrate complex controllers and sensors into the motor and cleverly "invisibly" within the frame. This not only maintains the iconic street vehicle look of Urban Drivestyle, but also makes the overall weight distribution more central and balanced, greatly improving handling sensitivity.
Three-in-one precise sensing creates a smooth "human-machine integration" experience.
Beyond its powerful hardware output, the soul of an electric auxiliary vehicle lies in the sophistication of its "electronic control system".
Unlike traditional single speed sensors, the UDX concept car incorporates sophisticated "three-in-one sensing technology" that can simultaneously detect the rider's wheel speed, torque (pedaling force), and cadence performance in milliseconds.
This intelligent power system perfectly solves common problems in electric scooters, such as "delayed acceleration at start-up" or "abrupt power intervention." Whether starting from a red light or facing an extremely steep slope, the system can provide precise power assistance in real time, making the rider feel that their pedaling power has been amplified several times invisibly, while still maintaining an extremely smooth and natural pedaling experience.
Two-stage intelligent evolution: converting cycling mileage into "carbon reduction and tree planting".
In addition to pursuing ultimate hardware performance, SEic and Delta have also incorporated ESG principles into their software blueprint. The intelligent functions of the UDX concept car will be implemented in two phases:
• The first stage:The system achieves a high degree of integration of the motor, electronic control, battery, and instrumentation. Riders can instantly and accurately monitor pedaling power, calorie consumption, and range, unleashing industry-leading acceleration while meeting the 250W power specification.
• second stage:It is expected to be integrated with a dedicated MyBike App. In addition to supporting Bluetooth connectivity, anti-theft navigation, and online OTA firmware updates, it will also feature an "ESG carbon reduction conversion function". The system will automatically convert the rider's riding mileage into carbon reduction weight (for example, riding 20 kilometers is equivalent to planting a tree), making green living a tangible achievement badge on your phone.
Comparison of core specifications between the UDX concept car and the classic model
| Standard item | UDX Classic | UDX concept car (equipped with Delta system) |
| Motor architecture | Rear wheel hub motor | Coaxial mid-drive motor (Mid-Drive Gen2) |
| Maximum torque | 65 Nm | 100 Nm (significantly increases output thrust) |
| main scene | Urban commuting, leisure, daily transportation | Mountain road climbing, off-road driving, and the pursuit of speed. |
| System integration | Distributed components | Coaxial high integration (controller/sensor integration) |
| Sensing technology | speed sensor | Three-in-one sensor (wheel speed, torque, cadence) |
| Controlling motion | The center of gravity is shifted to the rear, resulting in stability and smoothness. | With a centrally located center of gravity, it is easy to handle and has a balanced weight distribution. |
