While out on a ride yesterday, I happened to meet someone else on a recumbent who wanted to know more about my Vendetta. He had evidently never heard of a recumbent without a fixed boom, and was understandably puzzled by the MBB. In answer to his question about how difficult it would be to ride a MBB bent, I suggested that the learning curve for an experienced recumbent rider wouldn't be that steep. After all, it had only taken me one ride on the Vendetta before I felt pretty comfortable on it, but then I've been riding various fixed boom recumbents for years. I'm less optimistic that the MBB would be just as easy to learn on as a fixed boom design for someone completely new to recumbents. Not only would he have to learn all the basic stuff, like getting started from a dead stop and being able to avoid falling over without shifting your weight (as commonly done on a road bike), but in addition to that, he would have to simultaneously learn to overcome pedal steer, which introduces a whole new dimension of difficulty. Even after 600 miles on my Vendetta, I still have problems with pedal steer when starting from a complete stop, when resuming pedaling after coasting down a slope, and when shifting gears when sprinting or climbing a steep hill. In all of these cases, the problem occurs when your upper body movements temporarily get out of sync with your pedaling, so that you aren't able to produce the right amount of pull/push on the handlebars to perfectly counterbalance the amount of force produced by your legs. I imagine I'll get better at this as I accumulate more experience, but I don't expect that there will ever come a time when the problem will completely vanish.
