Frequently asked questions
Is Giant as good quality as Trek?
Giant makes frames for half the bike industry, including some Trek models actually. Their own-brand bikes use identical manufacturing standards. At equivalent prices, Giant often includes better components because they're cutting out more middlemen.
Why is Giant cheaper than Trek?
Giant owns the factories. Trek outsources manufacturing, often to Giant funnily enough. Giant also spends less on professional team sponsorships and flashy marketing. Lower overheads mean lower prices without compromising the actual bike.
Which brand is better for women?
Giant runs Liv as a dedicated brand with its own engineering team and geometry, it's not just paint jobs. Trek offers WSD (Women's Specific Design) versions of existing models. We'd give the edge to Liv here, they take female-specific design more seriously with purpose-built frames rather than painted-and-shrunk versions.
Which has better resale value?
Trek holds value marginally better because brand recognition runs a bit higher. The difference is maybe 5% on equivalent models though, nothing dramatic. Both sell quickly on the used market if priced sensibly.
