Reverse Two Seater Trike (Three-Wheeler) - Development and Optimization

We were tasked by one of our clients to engineer an Electric Truck Skateboard Platform designed to cater to the diverse needs of urban transportation. After putting a lot of mind throughout the design phase, we figured we shall design the platform to cater to a key aspect of urban mobilization – Flexibility. This product was designed to be modular in order to effectively serve various sectors including commercial, passenger, supply chain, and military applications. This makes for a much broader market using the same basic platform and manufacturing facility. We take pride in delivering a product that has a foundational design set in the field of electric mobility.

Proof of Concept: Initial Product Design

We designed an initial minimum viable product to serve as a proof of concept and to help the client pitch it to potential investors. This also allowed us to evaluate the vehicle's dynamics and performance under various conditions at a reduced cost. This phase enabled us to thoroughly test and refine the suspension design, ensuring it meets automotive safety and reliability standards.

This Vehicle is designed to utilize readily available aftermarket production parts & components, minimizing the need for custom part development and reducing costs.

An air-cooled engine coupled with an automatic transmission, powers the vehicle while the chassis is designed to be configurable for an EV variant in the future. On the rear, a belt drive system transfers the torque to keep things simple and easy to maintain.

Because of the target market, we were focused on making the vehicle comfortable and easy to use. This is why we had to design and develop an independent suspension system tuned for smooth ride. The final design incorporates bucket seats that offer ample leg space. The driving interface is that of a four-wheeled vehicle to give the users confidence behind the wheel.

Testing

Design Refinements Based on Testing Results

Following extensive testing of our proof of concept, we implemented several key adjustments to enhance the design. We refined the suspension system to improve stability and handling, creating a smoother and more reliable ride.

Minor upgrades were implemented to the vehicle's seating and driving ergonomics to increase comfort and user-friendliness, catering better to our target audience.

The rear trailing arm suspension was tuned to enhance durability and performance, providing better control and responsiveness while maintain better traction during turns and load shifts.

A roof was added to the final design to make sure the product offers more value for money and reduce the exposure of the occupants. This decision was based off multiple feedback polls where target audience demanded reduced exposure and better weather shielding.

The final design upholds most of the design elements added by the client. We offered the client a lot of different concepts, each with their own characteristics. Based off extensive production estimates and product pricing, a simple body design was chosen due to the lower initial costs for manufacturing as the startup looked to start small-scale production for this product right away.
