While affordable is good, you don’t want anything that is so cheap that it is going to compromise the quality of the bike. Most of the bikes that we have discussed above run between $100 to $200, which is a reasonable amount to spend. Be wary of anything under the $50 mark. Of course, if you are buying an adult bike, you can expect these prices to multiply by into several hundreds of dollars. Whatever you pay, don’t expect that the bike is going to last forever. The more you use it, the more that general wear and tear is going to become a problem.
