Some perspective. My BA is/was MY first bike. Got it delivered. Next day took it down the block. Dropped it trying to turn around. It sat for the rest of the winter till I took the MSF course in April. THEN I took it out again and went around the block a bunch, etc. So unless your wife is bigger than 6', 250, I think maybe she should start smaller

At the VERY least, take the MSF course to get a feel. Only bad part is you fail if you drop it...
