magnorail , in the procedure's of making a bike riding doing a constant wheelie, this is only the test run, i will tidy up the slide it runs on later - Also I have worked out a way to make the bike ride on 2 wheels and then pop a wheelie, that's still in the testing mode, will up date that part when its completed and working properly. ITs the first time I have ever owned a magnorail and I'm new to it, I didn't have any problem building the track layout like others say they do, though the chain can be a annoying cutting, smoothing it for hours. I found a lot of reject chain links in my set that was not moulded properly. I tensioned my track and chain first before screwing it down, work well the first time.
