About GIRDER
GIRDER (格拉德) is sold in China by 苏州格拉德自行车科技有限公司, a Kunshan company recorded in a public directory as established on 2015-01-27. The company's own site says it licensed a British brand, tracing it to the 1977 founding of the Edinburgh Bicycle Co-operative and to partners in Manchester, with China authorization in 2014. We found no independent evidence for that origin or licence, so it remains a company claim. A 2016 Biketo article calling GIRDER a domestic brand was published under GIRDER's own byline, not as independent reporting.

Brand-authored history. States that GIRDER Bicycle Technology Co., Ltd. was founded in 2015, introduced the British bicycle brand GIRDER and handles design, R&D and sales; positions products in the CNY 5,000–20,000 range. Claims the brand dates back to the 1977 founding of the Edinburgh Bicycle Co-operative, that partners in Manchester created the GIRDER brand, and that authorization to enter China succeeded in 2014. These origin and licensing claims are company-reported and were not independently corroborated. The HTTPS certificate had expired on access; the page was read over HTTP.
