Buy the bike you will ride. Keep the change.

Most family rides do not require a bicycle with the engineering budget of a space program. They do require a bike that fits, stops and makes you want to go again.

Start with the route

Choose the type for where you actually ride. Pavement, mixed paths and technical trails ask different things of a bike. Fit matters as much as the label on the frame. REI's bike selection guide explains the categories and fit considerations.

Compare ride-ready totals

For a new bike, ask whether assembly and an initial adjustment are included. For used, include an inspection and any immediately needed repairs in your price. Add a suitable helmet, lock and any lights you need to both options. Comparing a bare used frame with a fully equipped new bike is creative accounting.

Example only: a $180 used bike needing $120 of work costs $300 before accessories. A $280 new bike may be the cheaper start—or may not be the right fit. Price alone cannot settle that.

Questions before buying used

• What model, size and year is it? Can ownership be reasonably verified?
• Has it had a crash or frame damage?
• Do brakes and gears work correctly? Are tires, chain or wheels due for work?
• Will the seller allow an independent shop inspection?

Have a qualified mechanic assess anything you cannot judge. A visual checklist does not certify a bike safe. Walk away from unclear ownership, damage or pressure to decide immediately.

Spend on fit before features

Try the actual size. Consider where it will be stored and transported. A heavy bike that is miserable to lift may spend a lot of time being a garage decoration.
