This is not the case: first, the passenger capsules are completely enclosed and are climate controlled; secondly, the capsules are positioned on the outside of the wheel structure and are fully motorised; and third, the entire structure is supported by an A-frame on one side only. ''However the Singapore Flyer subsequently billed itself as the`` world's largest observation wheel'', despite being supported on both sides, and the official londoneye.com website also refers to the London Eye as ``Europe's tallest Ferris wheel ''.
