Comfort Bikes
The key is that comfort bikes let you sit upright which eases lower back strain. They also come with bigger tires that ensure a smooth ride, have raised, swept-back handlebars to reduce pressure on the wrists and hands and offer oversized seats to eliminate saddle soreness.
Keep in mind, that what you gain in ease when you ride a comfort or cruise bike, you lose in speed. The upright position is not exactly aerodynamic, so if you're looking for speed, or if you want to do some off-road riding on a bumpy mountain path, this would not be the bike to choose.
Comfort bikes are for pleasure, fitness rides around town, running errands, and generally to have fun and some exercise.
Recumbent Bikes
These are the odd-looking, low to the ground, stretched-out frame bikes that allow you to recline with your legs positioned in front of you. Recumbent bikes are very comfy, easy on the back and aerodynamic which makes them ideal for long rides and touring. The disadvantages, because they are low-to-the-ground, they are harder to balance and maneuver and are more difficult for other vehicles to see. They are also available in three wheel versions.
Tandem Bikes
Now here is a bike that you can have fun with, in particular if you plan to ride primarily with your spouse or another partner, consider purchasing a tandem bike that both riders can pedal at the same rate.
Folding Bikes
For boomers who like to travel, folding bikes have become very popular. Dahon offers the best variety of ergonomic
features including a low step-through frame.
