You are more than welcome to make your bike your own with 3rd-party accessories! Our bikes use standard bike components with traditional sizing, so many after-market bike products should work on our bikes without issue.
Before replacing any of the components on our bikes with after-market products (i.e. a new chain, pedals, tubes, tires, cassette, etc.) we do recommend you contact our technical support team first so they can give you insight into compatibility as well as if changing that particular component will impact your warranty.
We cannot give specific recommendations for any accessory or replacement part not found on our website as they have not been tested internally by our team.
