Introduction
TNT Moto Designs embarked on an innovative project to design and fabricate a vintage-inspired electric cycle named Vint-E. The primary objectives were to create a lightweight and affordable electric cycle suitable for tourism, capable of pedaling, throttle operation, and battery-assisted features. The weight target was set at 40 kg, and the range target was 70 km.
Design Brief
The Vint-E project was driven by a clear and ambitious design brief:
- Vintage Aesthetics: The electric cycle was to emulate the style of a 1930s scrambler motorcycle.
- Lightweight Construction: Achieving a weight of 40 kg required meticulous material selection and design optimization.
- Affordability: The design needed to be cost-effective to ensure accessibility for tourism purposes.
Engineering and Design Challenges
Weight Optimization
To meet the weight target, the team decided to use aluminum for the primary structure. Aluminum’s lightweight and durable properties made it an ideal choice for the frame and major components.
- Aluminum Structure: The frame and key structural elements were fabricated from aluminum, significantly reducing the overall weight.
- Fiber Plastic Components: The fuel tank storage and the front and rear fenders were made from fiber plastic, further contributing to weight savings.
- Polypropylene (PP) Plastic Engine Chamber: The mock engine chamber, housing the battery and Battery Management System (BMS), was fabricated from PP plastic to keep the weight low.
Power and Range
The engineering team focused on ensuring that the Vint-E met its range target of 70 km while providing reliable power for various terrains.
- Battery and BMS: The battery and BMS were crucial components, housed within the mock engine chamber. These systems were optimized to deliver a range exceeding the initial target.
- Hub Motor: A hub motor was installed in the rear wheel, offering efficient power delivery while keeping the weight distribution balanced.
Design Aesthetics
Maintaining a vintage aesthetic while incorporating modern electric components was a key challenge.
- Vintage Design Elements: The Vint-E was designed to mimic a 1930s scrambler motorcycle, with careful attention to vintage design cues.
- 26” Tires: Large 26-inch tires were selected to handle the varied terrains around nature resorts and hotels, ensuring a smooth and stable ride.
Final Outcome
The Vint-E project was a resounding success, meeting and exceeding the initial design targets.
- Weight: The final weight of the Vint-E was 38 kg, 2 kg lighter than the target, thanks to the efficient use of materials and innovative design.
- Range: The assist range achieved was over 90 km, significantly surpassing the original 70 km target. This was accomplished through optimized battery and BMS configurations.
- Vintage Appeal: The electric cycle’s design effectively captured the essence of a vintage scrambler, blending classic aesthetics with modern engineering.
Impact and Future Prospects
The Vint-E project demonstrated TNT Moto Designs’ ability to innovate and deliver cutting-edge solutions that cater to contemporary needs while preserving timeless aesthetics. The success of the Vint-E has opened new avenues for TNT Moto Designs in the electric vehicle (EV) market, particularly in the tourism sector.
- Tourism Applications: The Vint-E is perfectly suited for use in nature resorts and hotels, offering tourists a unique and eco-friendly mode of transportation.
- Expanding the EV Portfolio: The insights gained from the Vint-E project provide a strong foundation for developing future electric vehicles, expanding TNT Moto Designs’ portfolio in the growing EV market.
