Engineering Excellence

We combined real-world driver benefits with robust product features. Every component is chosen for durability and efficiency tweaked for Bangladesh 🇧🇩

Aerodynamic Design

Our unique retractable hood design significantly reduces air drag coefficient compared to traditional flat-front rickshaws. This optimization leads to a 15% increase in range per charge and better stability at higher speeds (up to 50 km/h).

Hydraulic Braking

Safety is paramount. We replaced the standard mechanical drum brakes with a triple-disc hydraulic braking system (Hand, Foot, Handle). This reduces braking distance by 40% and eliminates the risk of brake fade in heavy traffic.

Truss Chassis

Validated through ANSYS load simulations, our tubular truss chassis distributes stress evenly. It is 35% lighter than traditional angular chassis yet supports 80% more load (up to 700kg), preventing structural fatigue.

LiFePO4 Technology

We utilize Lithium Iron Phosphate batteries which offer 3000+ charge cycles (vs 500 for Lead-Acid). They are non-toxic, non-explosive, and provide consistent power output regardless of charge level.

Why TriChokro?

Driving the future of sustainable transportation with tangible benefits for drivers and the environment.

60%
Cost Reduction

Compared to traditional combustion engines, our EVs drastically cut daily operational costs, putting more money in drivers' pockets.

0 Emission
Better World for future

Zero tailpipe emissions mean cleaner air for our cities and a healthier future for the next generation.

3x
Safer Structure & Braking

Our triple hydraulic disk brake system provides superior stopping power, significantly reducing accident risks on busy roads.

The Economic Impact

"By localizing production in Bangladesh, we not only reduce import reliance but also create high-skilled jobs in engineering and manufacturing."
