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.
