Wife and I are 68. Bought each other custom configurated Surly Trolls for each other's birthdays, just a few days apart from our 38 wedding anniversary. Researching the various products, learning, finally selecting is the fun part. I had planned to assemble the bike myself, but the LBS wanted the work more than I wanted to save labor expense. So I say, this purchase of two trolls covers everything, and everything I should save done and should have gifted her but neglected to do so, since the time I bought her an iPhone 6+ and a new iPad
