A cheap used treadmill that is of poor quality can end up costing more in the long run. Things like repair and maintenance can really add up not unlike buying a bad used car. Never hesitate to ask questions if something seems off about the machine whether it is the belt not running smoothly or motor noises.

One good way to protect you is with decent warranty coverage. Some places will offer warranty on parts for the first few months you own the treadmill. It can be a good idea to pay a little money for extended coverage and be sure that it includes both parts and labor. Some manufacturers offer warranty only on the motor and not the other parts while other manufacturer warranties are not transferable to a second-hand owner. Make sure everything the salesperson promises is in writing and if possible take the extra step to contact the manufacturer support yourself and verify if the warranty is valid as the salesperson promised.

A good insurance against possible defects can be a big money saver but it is even more important to apply due diligence and research the treadmill before buying. There are many cheap used treadmills available in the market and online as well. There is never a reason to rush into a decision, nor buy if anything seems uncertain.
