What kind of wheels do recumbents use?
The 26-inch (559 mm) rear wheel and 20-inch (406 mm) front wheel combination is the most popular. Reasons for using other sizes would be more performance (650c or 700c), lowering of the seat (combos using 20- and 16-inch wheels), or making a bike more compact (20/16 combos). Small wheels don’t perform as well, wear more quickly, and have less gyroscopic inertia than their larger counterparts. Small rims and tire sizes can be more difficult to find. Tires: Consider using fatter tires than you would normally use. The reason is that you cannot deweight your wheels when riding as you can on a diamond-frame bicycle. Fatter tires are more comfortable, less skittish to ride, and have fewer flats.
