Good quality heavyweight bike (be warned, it's 40kg and much heavier than I expected but that's mostly down to my own lack of attention to detail when buying!) Interface is nice with some nice details like tablet holder. Saddle position, seat height, and handlebars are all adjustable which is good because the bike suits both me and my much taller partner. Big improvement on my little £99 folding bike which was not ergonomic at all. Haven't used the interval programmes yet but will try them soon. Easy enough to assemble, however I would say that the silver plastic covers on the top of the bike don't fit great and looking like they've been badly moulded or distorted when cooling out of the tool, so the seams are all a bit wonk! As this is merely decorative it wasn't worth the trouble of a return. All in all a good buy.
