The first bike that we put a WeeRide on an was Apollo LSX 1.2 (see picture) - infact you used to be able to see our daughter on the home page of http://weeride.com/ sitting on the seat of that bike - they've changed the photos now - here's the image.

Don't use the bike anymore - but happily rode with our daughter for well over 2 years on it. although it's hanging on the wall now - but as you can see it's cables run along the top. So I'd say yes - it will fit.
