Company History
GreenTrans emerged during Taiwan’s first serious push toward electric two-wheelers, focusing on practical city scooters designed to replace 50–125 cc petrol models. The goal wasn’t headline speed; it was livability—hub motors that shrug off rain, battery packs sized for daily commutes, and charging that works from household sockets. As incentives and municipal pilot programs appeared, GreenTrans supplied fleets for campuses and light-duty delivery, iterating quickly on waterproofing, connectors, and BMS accuracy after real-world feedback. While later entrants popularized battery swapping and app ecosystems, GreenTrans helped prove the base case: if an e-scooter starts every morning, reports range honestly, and is cheap to run, riders will adopt it. The company’s manufacturing partners in Taiwan’s mature supplier network improved consistency in plastics and looms, raising reliability over early prototypes. Historically, GreenTrans represents the groundwork phase of electrification—smaller brands taking risks before infrastructure and consumer habits caught up. Their scooters trained dealers on EV service, taught riders about charging discipline, and nudged regulators toward clearer homologation rules. Even where the badge is less visible today, the discipline of modular design and apartment-friendly charging that GreenTrans normalized still underpins Taiwan’s thriving e-scooter culture.
