- Extremely well made, stable even when sprinting out of the saddle at highest resistance. We've had ours 6 weeks, but experience with a 30 yr. old Concept2 Model C rower suggests that even in a gym environment these will still be going strong after other cycles have worn out several times over.- Pedaling response is like that of a nice road bike, more realistic than the friction or magnetic resistance of spinning cycles. After setting the damper for one's exertion vs. pace sweet spot, one can move between high intensity and recovery by varying pace over a modest range w/o touching the damper. (For full, out-of-the-saddle sprints I do max out the damper.)- US Made, responsive and knowledgable company assistance, little or no waiting. Concept2 stands behind their products, but builds them so well they there's little need for it.- The only negative (from my wife) is she can't smoothly perform spinning class style quick out-of-the-saddle jumps with it, nor when pedaling slowly out-of-the-saddle to rest without feeling a glitch or brief loss of resistance as the cranks go through vertical. I suspect her problem is with the cranks vertical she can't push forward/pull rearward sufficiently hard or fast to stay ahead of the flywheel's free wheeling clutch. In contrast, at high damper settings I have no trouble riding smoothly out of the saddle, but I also don't feel compelled to jump - I have real bikes for that. If this spinning class move is important to one's routine they probably should consider a dedicated spinning bike, paying about twice as much for equivalent build quality.- Other than jumping, for a solid workout of any intensity, including sprints, I don't think one can go wrong with a BikeErg.
