Donghai SM 750 (with sidecar) - Specifications & Review

Company History

Donghai appears among numerous Chinese manufacturers focused on essential mobility—durable, inexpensive step-throughs and scooters sold domestically and via regional importers abroad. The typical Donghai recipe centers on air-cooled singles, steel frames, and CVT or simple geared transmissions, with emphasis on load-carrying racks and fuel efficiency. In many cities and provincial towns, such machines underpin last-mile delivery and family transport, with dealers stocking consumables and common hard parts to keep downtime minimal. Over time, the brand’s offerings followed broader industry improvements: better wiring looms and connectors, tighter plastics, and EFI adoption in stricter markets. Electric three-wheel cargo variants have also entered the portfolio where regulations favor quiet, low-emission vehicles for dense neighborhoods. Historically, Donghai stands for the democratization of powered transport—the idea that mobility is a utility before it is a luxury. While little marketing lore surrounds the badge, the impact is tangible in kilometers ridden and paychecks earned. For owners, the calculus is practical: a bike that starts each morning, hauls what’s needed, and can be fixed with basic tools. That quiet competence is Donghai’s legacy.
