Yes, we take trade-ins! We can only give you trade in value here at the shop after inspecting the bike. Only "bike shop" bikes are considered, no department store bikes, huffy, pacific, mongoose etc. as we can not re-sell them. After we take a trade in, we go through the bike, replace parts that need replacing, tune them up and re-sell them to another rider. If you are shopping for a new perfect fitting bike bring your old one by and have us take a look at it for its trade value. Happy Riding!
