Flying Dodo
It'll soon be summer
Only up to a point; a lot of Apollos are indeed heavy, cheap & nasty - principally the ones built with low quality suspension forks or even worse, full suspension. The ones without any suspension - rigids, can make a perfectly acceptable low-budget bike. I use an old Apollo rigid MTB as a local hack. It must be about 25 years old, and I've spent less than £10 on it in total. Everything works and it gets me from A to B. It is fairly heavy at about 34 lbs, but then it's a cheap steel bike not something exotic made with Reynolds tubing - so I don't expect it to be light. It's best attribute is that it's not really worth stealing, and if some junkie did nick it I've only lost ten quid. It's not true to say that a £100 bike will not last, as mine clearly has lasted, so that is too simplistic a statement. It depends entirely on what sort of £100 bike it is. Some are utter junk, some are just budget quality but entirely useable bikes. The trick is to ignore the blingy looking junk with cheap chrome and flashy paint and go for the unexciting but solid type of budget bike without suspension.
£100 spent 25 years ago would have got a far better bike than £100 now. Modern Apollo bikes are rubbish, unlike your older model and a new bike at that price point won't last, especially when you look at the poor quality components that are now used.
