Optimization of steel bearings for urban cargo bicycle
Design and structural validation of a front-loading cargo bicycle frame, manufactured in 6061-T6 aluminum alloy, with a precision steel bearing system in the headset and bottom bracket.
Parametric three-dimensional mechanical modeling and finite element analysis (FEA) to evaluate fatigue resistance under cyclic loads of up to 150 kg gross weight. An analytical tablet was used for field data collection and deformation validation.
Generation of hexahedral mesh in critical areas (welded joints and bearing supports). Simulation of 10,000 maximum load cycles with a safety factor of 1.8. Adjustment of wall thicknesses in the top tube to reduce stress concentration.
22% reduction in total frame mass compared to the initial design, maintaining an estimated service life exceeding 50,000 km. A detailed industrial manufacturing budget was obtained for a batch of 500 units, with a unit cost reduced by 15%.

Milestones that defined the course of precision engineering in sustainable mobility.
We were born with the vision of transforming urban mobility through the industrial design of ultralight mechanical frames. The first cargo bicycle prototype was modeled in a workshop in Barahona.
We registered our first precision component patent: a high-strength steel bearing for drive shafts. This milestone consolidated our reputation in mechanical engineering.
We launched the first virtual course on high-end metallic material resistance, combining 3D modeling with structural analysis. Over 500 engineers were trained in the first year.
We developed a digital tool for industrial manufacturing budgets, integrating material costs and machining processes. We reduced quotation times by 60%.
We signed an agreement with the Institute of Sustainable Mobility to standardize electric bicycle components. Our three-dimensional technical drawings became an industry reference.
We were awarded the Latin American Industrial Design Prize for our modular frame system. Today, we export plans and technical consulting to 12 countries.
