Don't normally post in 50+.....usually in Alt Bike.......But I am 57, and have been building custom style bikes for a few years. WARNING: Be careful with the Footbikes, Kickbikes. Because they are VERY addicting! They're a great way to get in shape. But you don't have to be in shape to start "kickin". Are they worth the money.....Let me see, I just spent Sunday scootin around the neighborhood with my two youngest grand-kids. That ALONE makes it worth every penny. you can go as fast as you want or as slow as you want. Also my wife has a Kickbike City Cruiser, so we can go for "romantic" rides.......... instead of romantic walks.
I bike 10-15 miles a day, and have used the Footbike a few days a week. Guess what, this has made me a stronger cyclist (not an athlete, just like to ride). Legs are definitely stronger, even the one with the new knee. For me, I can't leave anything "untouched". This is my version of an Express.
