A friend of mine had bad balance, fell off his bike a couple times three years ago, bought a trike two years ago a month or two before Covid hit. He loves it. But, he is 85, has lost a lot of leg strength over the years. The trike is a Cattrike 559. Has a 26 inch wheel in back and a road triple crank. I think the shop sold him the wrong one, he would have been better off with a 20 inch rear wheel for lower gearing, he has trouble on some of the uphills. Because it is geared too high for him, I think he will convert it to electric this year.
