I doubt that iron man can keep up with a derestricted 500W BBS02 crank drive kit and 15AH bottle battery. Downhill yes, but not up hills.He is way past fanatical.....he is full blown iron man 100 miles every sunday....but i rekon if i can do a 50 mile 'short ride' at a good pace then it wont be as painful for him to go out with me! lol
