Whatever you do please DO NOT buy the Blackburn.
I bought one and that thing was way off on assimilating road conditions. At the store they told me about the gears, break in period, type of tire, bla bla bla...
Its not consistent at all, one moment is fine and then out of the blue when increasing speed is super hard to pedal. I even opened it up to verify the ball bearings were not getting jammed or in the incorrect position, double checked nuts and bolts to see if anything was making it run erratic and inconsistent. No matter how much I hate to return expensive things I really had no choice as it was a POS for how much it cost me.
Edit: this is what happens when I do not read the whole thread, by the way how does that one perform?
