Pipedream Cycles is a British mountain-bike frame brand founded in 2005 by engineer Alan Finlay. Originally producing titanium frames, it now concentrates on steel hardtails with aggressive, long-and-slack geometry aimed at trail and enduro riding.

Signature models include the Moxie and Sirius hardtails and, from 2023, the Full Moxie single-pivot steel full-suspension frame. In 2024 the company was acquired by Scottish firm Route Assembly, which set out to bring frame production to the UK.
