Most of the bikes available for rent in Taiwan are fine for a few hours leisurely touring but are too small or otherwise unsuitable for long-distance cycling. Fortunately, Giant – one of Taiwan's leading bike manufacturers – rents high-quality bicycles through some of its outlets.
Bicycles can be rented at one shop and returned to another branch. The basic fee for three days or less is NTD1,200, with each additional day costing NTD200. Bikes should be reserved well in advance and payment must be made by credit card; you'll be asked for your height and some other details. There's no central website in English or Chinese because the programme isn't being heavily promoted, but email the Hsinchu branch (email@example.com) and you'll get sensible answers in English.
