Easy to put together, but poor instructions for actually making it work. Luckily I'd read some of these reviews, which had mentioned a small switch (difficult to spot) on the handlebar upright which you need to have in the correct position for it to work with the Wii. I'm sure lots of people who complained that they couldn;t get the cyberbike to work hadn't discovered this switch. There are no instructions for using the cyberbike disc, so you have to work it out for yourself, which is therefore slow and frustrating. this could be easily remedied, no excuse for this kind of poor service. Having said all of this, I'm really enjoying using the bike, the story mode is good fun and time passes in a flash. It's very easy to cycle for 3/4 of an hour without realising it. I'm getting fitter!
