Vests and helmets for a public bike-share system in Mexico City
The operator of a public bike-share system with 480 stations across Mexico City needed to outfit 320 mechanics, supervisors and community monitors. We produced high-visibility vests, certified helmets and reflective kits in six weeks.
Client context
The system runs a fleet of 6,500 bicycles distributed across boroughs such as Cuauhtemoc, Miguel Hidalgo, Coyoacan and Benito Juarez. Operations had 320 field staff: mobile workshop mechanics, station supervisors, community monitors and incident response personnel. Each role had a distinct uniform and staff turnover was high.
Management launched a road-safety campaign that included three pieces per staff member: a class 2 high-visibility vest with reflective strips, a helmet certified under NOM-133, and a kit of reflective accessories for the personal bicycle (wristbands, tire bands and an LED front light).
The operation had to be coordinated with the quarterly staff training calendar. The previous supplier had delivered batches with mismatched sizes and vests without EN ISO 20471 certification. Management wanted a partner that would deliver certified pieces with upfront size capture and a safety margin to replace worn items.
The client clarified that invoicing had to follow local government rules: CFDI 4.0 with 16% VAT breakdown, framework contract with a quarterly FX-adjustment clause, and monthly inventory reports for audit by the city's Mobility Secretariat.

Methodology
The vest was fluorescent yellow mesh with two horizontal and two vertical reflective bands, certified under NOM-133-STPS-2009 and EN ISO 20471. The base fabric is 100% polyester with water-repellent treatment. It was produced in two versions: a front-closure version for mechanics and a side-opening version for supervisory staff.
The helmet was manufactured at a plant in San Luis Potosi with an ABS shell and expanded polystyrene inner suspension. It features an adjustable nylon strap and an occipital adjustment wheel. Certification covers impact and penetration tests. Each helmet was marked with an internal serial number and a QR code for individual assignment.
The reflective kit included two vinyl wristbands with velcro closure, two tire bands in flexible PVC, and an LED front light with a silicone mount and three lighting modes. Everything was packed in an individual bag with Spanish installation instructions.
Size capture was done in person at three zonal workshops of the operator over a week. Special sizes were covered through direct factory orders at no extra cost, within the 7% safety margin over the initial calculation.
We closed the cycle with a joint retrospective. The client leadership and our account team reviewed the indicators from each phase, identified recurring friction points and proposed improvements for the next cycle. The conversation was documented in an act signed by both parties, which served as the basis for the client internal operating manual and as a reference for future projects with other operators in the sector. This closing discipline, uncommon in the merchandising industry, has differentiated our value proposition and has generated organic referrals among operations leaders at sister companies in the group.
Results
The operator reported a 42% drop in field incidents involving third parties during the first quarter after delivery, attributed to the combination of visible vests and certified helmets. The Mobility Secretariat audit verified the certifications without observations.
HR cut wrong-size exchange requests by 68%. The 7% safety margin covered staff turnover over the following six months without additional purchase orders. The operation was replicated for a similar system in Guadalajara during the second half.
The client internal operations team documented additional savings in man-hours spent preparing each kit before season start. Before the project, the supervisor at each location spent half a day per week reviewing sizes and sorting pieces; with the new scheme, that task disappeared from the operating calendar. Monthly replenishment consolidated into a single order leaving our El Marques, Queretaro hub, with delivery at each base in less than five business days.
From a commercial perspective, the client reported growth in the post-delivery recommendation rate, measured through the online survey every recipient receives after receiving the product. Reuse of pieces in social media by end users generated organic content equivalent to several tens of thousands of pesos in paid media during the first quarter, per the marketing area estimate.
The tax team validated the CFDIs issued under the general legal regime, with 16% VAT breakdown in each invoice when applicable. The client claimed the expense deduction in its annual return as part of operating expenditures, representing a tax benefit close to 35% of the invoiced amount. The operation set a precedent for the annual renewal of the programme, with minor catalogue adjustments to incorporate new pieces or recycled materials based on market demand.
Lessons learned
- EN ISO 20471 and NOM-133 certification must be verified with a physical sample and documentation, not only a technical sheet.
- In-person capture at zonal workshops prevents mass returns from incorrect sizes.
- A 7% safety margin is reasonable for operations with high staff turnover.
- Direct communication between the production team and each location lead dramatically reduces rework driven by last-minute changes. Reuse of the pieces by end recipients is an unplanned marketing asset: designing pieces that withstand continuous use multiplies brand return without additional paid media cost.
