Excellent! I was hoping the revised version of this would be up. First of all, very impressive visually; I love the color scheme. I also like how you tackled the problem of going over the bump. It looks like you won't have any problems with that.
Unfortunately, it looks like your center of gravity will have moved up quite a bit, which may pose a problem with tipping, though that's just from looking at it, so don't take it as a fact.
And one more thing that Im just echoing from the first revision. You want to be careful with that suspension to make sure that if one wheel's springs are compressed and the others are in the normal position, it doesn't throw your chain off.
Other than that, it's an impressive design that looks quite promising. Good luck!
