Have you personally inspected and/or test-ridden either bike? I have inspected the IOS 9 and other Eclipse models, but have test-ridden neither. IMHO, they are both high-quality items. Thor may be one of the few participants in this forum who has some first-hand knowledge of both models. And, as he states, if you are wanting to buy a new bike, availability of the IOS may make that issue moot.
