Im a rodie that tried out a friend's Warp. The thing actually had a computer on it and I was supprised how fast I got it to go on the street when I hammered on it. Maybe something like a Giant NRS2 could keep up with a road bike? Thinking of getting one just cause of the versibility and it was REALLY fun to cut across the street, go up over the curb, and another, the grass, and etc.....real fun! a real blast! Never happen on a road bike.I think I could really get into this. Just wondered how fast one could expect something better like the NRS to go on the street with the combination type tire .???
