Defective Items:

We love the suppliers we work with and those relationships come in handy. We will go to bat for you. Each product has it's own manufacturers warranty. Contact the store for each brands specific product warranty.

Automotive Bike Racks:

Automotive bike racks have a 14 day return period and are subject to examination by our staff.

Bikes:

Your first assignment when you buy a new bike is to fall in love with it. If you don't, you have 14 days to return it in new condition. Often times we find that it's an adjustment that can make your bike feel a lot better. Maybe consider having afitting done. After 14 days you have 1 year of free service. We will make any adjustments for you for the first year you own your bike. We do not cover damaged parts or issues caused by neglect. We will repair any flats you have for the first year you own your bike. Flat repair covers the cost of the tube and labor.

Skis and Snowboards:

Your first assignment when you buy a new ski or snowboard is to go skiing or snowboarding and how the new equipment does on the slope. You have 14 days to return it in new condition. Often times we find that it's a binding adjustment that can make your skiing faster or snowboard turns tighter.

Service Work:

We work on just about every type of mechanical bike. If you think you have something weird, give us a call and let us figure out how we can help. We do have to draw the line at some e-bikes. If it's not a brand we are familiar with, we may refuse to work on it. Typically we'll be able to do the mechanical work but we will ask you to leave your battery at home. Some Lithium Ion batteries can be dangerous and we need to take precautions.

We want you to be happy with your bike. When we see service bikes come back to us we want to get it right.There are so many variables when dealing with those bizarre pops and clicks that sometimes we've fixed a "pop" and you wanted the "click" fixed. For that reason, we cover our service for 6 months from the date of repair. All replacements and warranty work is to be done at Spoke-N-Sport.
