Mrs. DB logged 1.1 miles last night on a borrowed Sun trike. This is huge. Long story short, she has nerve issues that jack up her back, neck, legs, etc. Good days mean a cane, bad mean a wheelchair or walker. No pain from the trike, and she really likes the downhills in my neighborhood.
Yes, I know...no helmet. But, 5mph on a trike in my 'hood is pretty safe. If we buy it, she gets a helmet, flag, bottle cage, etc.
