Great bargain, however, I would clean them, then sell them on
ebay for a hefty profit
then, save up a bit more, and search ebay in Spring next year and get another bargain that you will keep for long, and use often
looking at those bikes, on ebay you can expect £60-£70 per bike but you would need to list them with a buy it now at £80 with best offer .... be patient and dont accept less than £50 .. that would give you £150-£180 min ..... add another £150 and you will get a really good bike off ebay if you are patient and search ebay daily for new listings
