RETROFIT

Axle-Based Electric Retrofit · Gen-1 System

Electric assist for existing cargo trikes ; without replacing the vehicle or the livelihood.

Tirare is a non-invasive, axle-centric electric retrofit system for cargo trikes and cycle carts already in use. It reduces physical strain while preserving ownership, serviceability, and local repair ecosystems.

CONTEXT · HUMAN LOAD · URBAN LOGISTICS

Manual cargo movement relies on sustained human strain.

Across Indian cities, millions of workers move goods using pedal-powered or manually assisted carts. These systems demand sustained physical output under load, often for 8–10 hours per day, with limited mechanical assistance.

  • PHYSICAL LOAD Continuous exertion exceeding sustainable human output during starts, inclines, and stop–go traffic.
  • HEALTH IMPACT High incidence of chronic back, knee, and joint injuries linked to repetitive high-torque effort.
  • ECONOMIC CONSTRAINT Daily income is directly tied to physical endurance rather than efficiency or distance covered.

OPERATING CONDITIONS · THERMAL STRESS

Rising ambient temperatures amplify physical risk.

With summer temperatures regularly exceeding 45 °C in many regions, sustained physical labor under load becomes increasingly unsafe. Heat stress, dehydration, and exhaustion compound existing mechanical strain.

Under these conditions, reducing peak human effort is not a comfort upgrade ;it is a safety requirement.

NON-HUMAN LOAD · ETHICAL CONTEXT

Animal-powered carts remain part of urban logistics.

In several cities, horses, donkeys, and oxen are still used to pull heavy cargo under high ambient temperatures. These animals are subjected to sustained load without mechanical assistance, rest intervals, or adequate hydration.

When fatigue or collapse occurs, outcomes are often unmanaged due to the absence of alternatives rather than intent.

Electrifying load assistance removes the need for animal traction in short-range cargo movement ;improving welfare without disrupting livelihoods.

Ground Reality

This is not tradition. This is abandonment.

In Indian cities, elderly rickshaw drivers continue working into their 70s and 80s ;not by choice, but by necessity. When strength fails, they do not stop. They step down, and pull.

SYSTEM ARCHITECTURE · NON-INVASIVE ELECTRIFICATION

An axle-based electric retrofit ;not a new vehicle.

Tirare is a modular electric assist system that retrofits onto existing cargo trikes and cycle carts. It injects controlled torque at the axle, reducing peak human effort while leaving the original vehicle, ownership model, and repair ecosystem intact.

  • NON-INVASIVE No frame cutting, no wheel replacement, no permanent modification to the original cart.
  • AXLE-CENTRIC Torque is delivered through a mechanical reduction unit coupled to the existing axle, optimized for low-speed, high-load operation.
  • LOCALLY SERVICEABLE Uses standard components and simple interfaces compatible with local workshops and mechanics.

DEPLOYMENT · OPERATOR-OWNED

Retrofit kits installed on the operator’s existing vehicle, reducing fatigue immediately without disrupting daily work.

DEPLOYMENT · PILOT / CSR

Limited-run field pilots to validate thermal behavior, durability, and real-world effort reduction before scale.

The goal is assistance, not replacement ;engineering support for work that already exists.
