^this is sound logic. However, if your reasons are simply that you'd like to try it out, or that a new shiny thing might be fun, or some other reason, then think hard about it.

1) Expense. The true cost of ownership includes not just the substantial entry fee, but also any replacement parts that you might foresee over, say, 5 years. Are there components that are unproved, or that might be prone to failure? Consider the full costs.

2) Complexity. Are you a do-it-yourselfer? So, you'll be taking on the troubleshooting, maintenance and repair of these additional component parts, too? Is that what you want? Have a voltmeter, continuity checker, and troubleshooting skills? If not, you'll pay. See #1 .

Those would be two reasons to consider. Me, I'm 60, fit and a pretty strong rider. I have no immediate need for help. I like my bikes as they are. But, things always change, don't they?
