OP linked to 'performance bikes'... a franchise or company owned chain.. they sell over the internet too..

Often what separates 'A Good bike' from one disappointing is the assembly Mechanic's skill &focus,

and the service after the sale of the Seller. and those are unknown by Me, I can only speak about My Local.



since the same few factories ship out multiple Brands to dozens of Importer-distributors..
' brand ' is often just the name painted on in following the export contract.
