Because we are an authorized dealer for all the brands we sell on our store, we can make sure that you are getting the best price on the market for all of our products. Our manufacturers have what's called a MAP (Minimum Advertised Price) enforcement policy which ensures that we can offer you the lowest possible price in the industry!

If you find any other store selling the exact same item we have on our store but cheaper, then we will match that price, even if you've already purchased from us!

All you have to do is contact us here! 

There are exceptions where our Price Match Guarantee doesn't apply:

- The store you found is not adhering to the manufacturer's MAP policy. Some stores try to cut corners by slashing prices below the manufacturer's MAP pricing, which is not allowed by the manufacturer. The reason it is not allowed is because the customer usually gets a horrible product or service. 

- The store isn't an authorized dealer by the manufacturer.

- The item must not be part of a special promotion, sale or offer.

- Our manufacturers occasionally change the prices of some items. We change the prices to match our manufacturer's MAP policy. The Price Match Guarantee doesn't apply to orders placed on our website in the past where the item's price was higher.

We guarantee you that you are getting the best possible price in the industry. We know that because it's illegal to offer any lower prices than our manufacturer's MAP policies ;) 

If you find a cheaper price than ours for any particular item(s), please contact us and we'll get back to you as soon as possible! If all checks out, we'll match that price for you!

Although we make it our mission to provide you with the highest quality products and the best customer service in the industry, we understand that sometimes things just don't work out. 

If you are not 100% satisfied with your purchase, then we are here to help!

What Should I Do If My Order Is Damaged?

    Quick shipping + an extra bike lock

    The shipping from ebike vault was very fast I only had the problem with FedEx that they kept putting me off for at least 5 days delayed shipping through them otherwise I would have had it five days later after shipped what can I say this bike is Big it's bad and it's heavy it's one monster bike and it rides really comfortable. I'd like to thank e-bike vault for responding to all my questions very promptly and I would say get a bike through these people I did have my money down for a sondors but they kept continuously changing the ship date and so I found ebike vault and chose them and the next day the bike was shipped. And I'm very happy I did thank you once again.

    What a great bike

    My boyfriend has had an e bike for a year and I had a standard pedal bike. His is exactly the same bike in almost every regard except a few add ins like rack and fenders. I actually paid a little less and got a bit more with e vault. That been said, I would struggle trying to go where he could go with his pedal assist and it started to take some of the joy out of riding together. We live in a hilly area. Now we can explore much more and never worry about how tired we are or saving energy for the trip back or whether it’s up hill! Opens up a whole new aspect to riding bikes.
