Very bad experience with Mammoth Bikes

I had a very bad experience with Mammoth Bikes. I ordered a SPECIALIZED Turbo Creo 2 Expert at Mammoth Bikes. To fix the fenders and some other things I brought the bike to a Specialized garage. They informed me, that the speed wire was not in place and that it has to be fixed. I had a look at the situation and can confirm, that the fixation of the wire was not correct. The garage had to refix the wire. I informed Mammoth about the situation and asked them to share in the costs for the fixation. Unfortunately, Mammoth was not in the least willing to contribute to the costs. I'm sorry to say I cannot recommend Mammoth to anyone looking to buy a bike.

Thank you for sharing your experience, Thomas.
We have reviewed your case and would like to clarify that the bicycle was inspected prior to shipment. Furthermore, it was connected to the Specialized diagnostic system, and no errors were detected.
In your initial communications, you indicated that the speed sensor cable was not installed. However, in your subsequent review on Trustpilot, you noted that the cable was present but not properly secured. This discrepancy makes it difficult to determine the exact nature and origin of the issue.
Additionally, you informed us that the bicycle had been taken to an independent workshop for the installation of mudguards and other work before you reported the problem.
We understand your dissatisfaction; however, based on the information available, we cannot confirm that this is a manufacturing defect, nor can we cover the costs of the work performed by the independent workshop.

I had a very bad experience with…

I had a very bad experience with Mammoth. The replacement parts are being sent out with weeks of waiting time and repetitively to the wrong addresses. I would never purchase from this company again.

We regret that your experience has not been satisfactory, although we would like to clarify a few points. In this case, this was not a purchase but a warranty claim, a process that may require a certain amount of time to complete and for the replacement part to be received.

Regarding the shipment, the replacement part was sent to the address provided in your original order. Although you subsequently requested a change of address, unfortunately, we were unable to make the change in time.

We apologize for the inconvenience caused and appreciate your understanding.

I don't recommend

Unfortunately, a total failure. I ordered a bike rack to go on vacation. After a week of waiting, it turned out that they sent it to the wrong address. Now I have neither the trunk nor the money because the refund will be made, of course, after another week when the trunk returns to them. My first and last purchases in this store!!!

Reply from Mammoth Bikes

We are sincerely sorry for what happened, and we completely understand your frustration, especially as you needed the bike rack for your holiday.

However, in this case, the shipping company has informed us that the delivery address provided for the order was incorrect and, for this reason, they returned the package directly to us. Unfortunately, the carrier did not give us the option of arranging a new delivery to a different address.

This situation also results in additional shipping costs for us, which, as you can understand, is not something we want to happen. Nevertheless, these costs are incurred when the parcel has to be returned to our facilities.

As soon as we receive the package back, we will process the refund for the full purchase amount as quickly as possible.

We sincerely apologize for the inconvenience and understand that this has not been the experience you expected.

Delays…

After ordering a bike I got an email stating that the parcel was shipped and so was the information on my account. After 2 days when the status was not changing I contacted them to ask what is going on and it turned out that the order wasn’t even sent yet! They kept assuring me that it will be sent “soon” and after next two days of waiting when I asked for a specific date of shipping they said the parcel won’t be able to make it before my holiday to pick it up. They have such a mess that two weeks is not enough to ship a bike.

We are very sorry for the inconvenience caused and for the delay in delivering your bicycle.

We understand that the wait may have been frustrating. In our terms and conditions, we explain that, for bicycles, delivery times are always estimated, as they must first go through our workshop for preparation, inspection and proper packaging before being shipped.

During periods of higher workload, such as the current one, these processes may take slightly longer than initially expected.

In any case, we always work to ensure that each bicycle is dispatched as soon as possible and, especially for deliveries to distant destinations, with the necessary packaging and protection to ensure it arrives in the best possible condition.

We sincerely apologise once again for the inconvenience and thank you for your patience and understanding.

Avoid at all cost

Avoid at all cost. You can end up like me, paying a few thousand euros for a bike and all you get are emails about how the bike is waiting to be packed. This argument has been going on for several weeks now. Better choose an e-shop that takes the sale of goods responsibly, otherwise you can end up like me without money and without a bike.

UPDATE:
Finally my order was sent. But not by DPD, GLS, Fedex or any other well-known company. It was sent by Redur. A company that has a 1.3 star rating on Trustpilot. According to the tracking of the Redur shipment, four days after the shipment was sent, Redur does not have my shipment or any information about it.

A truly terrible customer experience.

A truly terrible customer experience.

I ordered a product in January, but it wasn't delivered until April—almost three months late. By then, I had every reason to believe the package was lost, so I had no choice but to purchase the same product from another retailer.

As a result, I ended up with two identical products.

Despite the fact that this situation was entirely beyond my control, Mammoth refused to offer any commercial solution or refund. Even worse, they eventually stopped responding to my emails altogether.

Delays can happen. However, the complete lack of communication, the disregard for customers, and the refusal to take responsibility for the consequences are simply unacceptable.

The true measure of a company is how it handles problems when they arise. In my case, Mammoth's customer service was nonexistent from start to finish.

I will never buy from Mammoth again, and I strongly discourage anyone from doing business with them.

Reply from Mammoth Bikes

We believe it is important to clarify the facts.

According to the carrier's records, the order was successfully delivered in January, with a signed proof of delivery.

Several months later, you contacted us requesting a return. However, your request was sent from a different email address than the one used to place the order, and the name provided also did not match the details associated with the purchase. For data protection and security reasons, we cannot process requests or disclose order information unless they come from the account used to place the order or from the verified purchaser.

For this reason, we asked you to contact us from the original email address so that we could review your case, even though the order was already outside our standard return period. Unfortunately, we never received any communication from the email address associated with the purchase, so we were unable to continue our assessment or verify the circumstances you described.

We always strive to help our customers whenever possible. However, we must also apply the same data protection and security procedures to every order in order to protect our customers and prevent fraudulent requests. We regret that we were unable to take the matter any further under these circumstances.

Quality of the customer support - NOK

I was not satisfied with the quality of the customer support I received.
My questions were not properly investigated, and the responses I received did not reflect the actual status of my shipment.

For example, I was informed that tracking information would only be updated once the parcel arrived in Slovakia. However, I had previously received an order from your store via GLS, and the tracking was updated throughout the entire journey, including while the parcel was passing through other countries. Furthermore, the tracking was eventually updated while the parcel was still in Germany, proving that the information I had been given was incorrect.

Later, I was informed that the shipment had been returned to Spain due to an error by the shipping company. This important information was only provided after I repeatedly contacted customer support to ask about the unusual delay.

I expected my concerns to be investigated more thoroughly from the beginning and to receive accurate information about the actual status of my order.

We are truly sorry that your experience did not meet your expectations.

Unfortunately, your shipment was affected by an error on the part of the carrier, who returned the parcel to Spain during transit. As soon as it was received back at our warehouse, we arranged for it to be shipped again immediately to avoid any further delay.

We also wanted to acknowledge the inconvenience caused, which is why we refunded the shipping costs as a gesture of goodwill.

We sincerely regret that, despite our efforts to resolve the situation as quickly as possible, the overall experience was not satisfactory for you. Your feedback is valuable to us and helps us continue improving both our communication and our customer service.

We apologize once again and thank you for taking the time to share your experience.

Bike Lost, Months of Poor Communication

I would strongly advise anyone considering buying a bike from Mammoth to think twice based on our experience.

We placed an order for a bike on 8 April. The bike left Spain on 14 April, but after that we received no meaningful updates about its whereabouts. We repeatedly contacted customer service asking for information, but the responses were vague and gave no clear explanation of what had happened or what Mammoth was doing to resolve the issue.

The most frustrating part was the lack of communication. We were never proactively informed that there was a serious problem with the shipment and had to keep chasing for updates ourselves.

By early June, after nearly two months of uncertainty and repeated attempts to get answers, we sent a formal email explaining that we would take further action if the matter was not resolved. Rather than acknowledging how poor our experience had been or apologising for the situation, the response we received was defensive.

Mammoth eventually admitted that the bike had been lost. While they did refund us in full, there was no attempt to offer a replacement bike, discuss alternative options, or find a solution after we had already waited so long. Instead, after months of uncertainty and repeated emails, the matter was simply closed with a refund.

The refund was, of course, the right thing to do once it became clear the bike was lost, but it did not make up for the time wasted or the lack of customer service throughout the process. After everything we went through, it felt like the easiest option for Mammoth was simply to refund the order and move on, rather than make any effort to put things right.

I understand that delivery problems and lost shipments can happen. What matters is how a company responds when they do. In our experience, Mammoth failed to communicate openly, failed to keep us informed, and left us to do all the chasing ourselves. The only part of the transaction that worked efficiently was taking our payment.

Based on our experience, I cannot recommend buying from Mammoth.

We are deeply sorry for the experience you had and all the inconvenience this situation caused you.

Unfortunately, your bicycle was lost in transit. From the moment we became aware of the problem, we launched an investigation and did everything we could to expedite the process. However, when a shipment is handled by a third-party carrier, we are dependent on their procedures and investigation timelines, which are not always as quick as we would like.

We fully understand the frustration the wait and uncertainty caused you, and we sincerely regret that our communication did not meet your expectations during this process.

As soon as the carrier confirmed the bicycle was lost, we immediately processed a full refund for your order.

We appreciate you taking the time to share your feedback. It helps us review our procedures and continue improving how we communicate and support our customers when unforeseen situations like this occur. We apologize again and wish you all the best.

Made me paid the VAT when was indicated…

Made me paid the VAT when was indicated that was included, and then they lied and spoke with superioririty. Then, you reply to this comment saying you try to reach me to solve me, you only reached me to tell me I had to pay the VAT and that is my fault and not yours, liars.

We regret your feedback. We are in contact with you and have tried to resolve the issue. It was a mistake by the transport company, as you have indeed paid VAT and do not need to pay it again. We hope to resolve this as soon as possible.

Mammoth bikes Order to the UK

First time using Mammoth bikes. Delivery to the UK. Item delivered was a used. Return was accepted but the returns process is really difficult as items have to be collected due to customs. It’s took weeks to get this sorted, involving a PayPal claim. I got my money back but it was a stressful experience. I do not recommend mammoth bikes for Uk delivery it’s not worth the hassle.

We are very sorry to hear about your comment. We have tried to resolve it in the best way possible, and as you indicated, your money has been refunded. The customs issue is complicated due to the time involved, as they take a long time to process and return the merchandise.

We will try to improve in any way we can.

No Bike/No Updates/No Accountability

I've read many reviews on this site regarding late/non-existent deliveries as well as a lack of communication by this company. I was a fool not to check the reviews before ordering from them, because I recently had a similar experience. Thankfully, I received a full refund in just a couple of days.

I trusted this company because I had success ordering helmets from them a couple years ago. This time, I ordered a bicycle - I was given a two-to-three-week delivery schedule, so I waited patiently for 16 days (with zero updates from the company). When I contacted them on Day 17, they told me that my bike was being prepared for delivery "today or tomorrow" - after these two days passed with no delivery information, I cancelled the order the following day. They replied that my bike was ready for delivery, but I no longer trusted their words - it was my opinion that they were waiting for the bike to be delivered to them and lied in an effort to prevent me from canceling my order. Of course, I cannot prove this - but none of us can prove such shady activities.

I've noticed a theme on this review site - the company responds to most of the negative reviews, and they claim to be victims of misunderstandings; however, they don't seem interested in improving their faults. They never accept responsibility for their lack of communication, and they act shocked when anyone reports a negative experience. If only they communicated as effectively with their customers as they do when responding to a negative review!

If they had simply sent me an email telling me that my bike was delayed, I would have trusted them more. Perhaps they are overly disorganized or merely lazy, but the stories on this review site seem to indicate that they are not proactive with their customers. Perhaps they should use these reviews to improve their business activities, but they obviously don't seem interested in changing their behavior.

We regret that this was your perception of the experience, but we believe it's important to clarify a few points.

First, your order did not meet the estimated delivery time indicated at the time of purchase. When you contacted us for information, we responded immediately, informing you of the status of your order and that the bicycle was being prepared for shipment.

Subsequently, when you decided to cancel the order, we processed your request without any objection, canceling it and issuing a full refund, which you received very quickly.

We respect your decision not to wait any longer for an order, but we cannot agree with the claims about alleged dishonesty or "shady dealings," as they are unfounded. Furthermore, we consider it unfair to extrapolate this perception to the general operation of our company, especially since in your case the cancellation and refund were handled quickly and without incident.

We work every day to provide the best possible service and welcome constructive criticism, but we also believe that public reviews should objectively reflect the facts. In this case, we understand that this review damages our reputation without accurately reflecting what happened during the handling of your order.

Stock issues, can't reach them

Ordered a shirt and a few things but they answered a few days later that they don't have the majority on stock but they want to send me the rest.
I can't contact them because all their mailboxes are full and don't receive mails.
On the website I managed to fill the contact form and I got a reply pretty soon.

Easy shopping and return policy

Bought some spare parts from them with a pretty good price. Everything went well. Delivery on time. Had to return something because I made a mistake with my order and the return process was very smooth and exceptional. Very good experience that led me to buying a gravel bike from Mammoth Bikes a month later. Contacted support with a question and got a prompt reply. Delivery on time. Very efficient store with good deals. I am a very satisfied customer!

Disappointing experience: Sold opened items as new

I ordered the Cannondale Cargowagen Neo Surround Rails, expecting a brand new, sealed product. However, the package arrived having clearly been opened, and several essential parts (M6 washers and spring washers) were missing. The remaining hardware was just loosely thrown into a hand-tied plastic bag.
I honestly regret not inspecting the contents immediately upon arrival. I never expected that essential assembly hardware would be missing from a brand new product. Because four weeks had passed before I noticed the issue, I fully understand that my claim may not be considered valid under the shop's 24-hour reporting policy.
However, when I contacted customer service to address this and requested that they simply send the missing washers, they refused, stating that my request could not be accepted due to the time elapsed. They ignored the fact that this is clearly a warehouse/packing error. It is unacceptable to sell returned or B-stock items as brand new without disclosure.
Most concerningly, these are safety-critical rails for a child passenger. The essential hardware for securing the rails to the bike frame—specifically the lock washers—were missing 3 out of 4. Selling an incomplete, safety-sensitive item and ignoring the customer’s safety concern is completely irresponsible. While I accept my part in the delayed inspection, the primary responsibility for providing a complete and safe product lies with the seller, especially when it concerns children's equipment.
My advice to future customers: even if the package looks fine, be sure to open and inspect every single part immediately upon arrival. Unfortunately, I cannot recommend this company due to this experience.

Hello,

We sincerely regret that your experience was not satisfactory and apologize for the feedback you left.

However, we received your message approximately one month after the item was delivered. Due to the time that has passed since receipt, we cannot determine whether the condition of the packaging or the product corresponds to the time of delivery, as the item may have been handled afterward.

For this reason, and because the issue was not reported within a reasonable timeframe after receiving the order, we are unable to address your request at this time.

Thank you for your understanding.

Unexpected delivery time

I bought bikeframe. Unfortunately, the delivery is taking longer than I expected, and I saw this on the website. The delivery to Cyprus took 1 month, I think because the package went through several countries and frame was going from provider to Mammoth some time.

Great communication with Mammoth Bikes

Communication with Mammoth Bikes was great - I bought a Cannondale Habit HT which didn't come with the seatpost that was on the spec sheet. Although it took some time, Mammoth made sure that Cannondale gave me the correct seatpost. Much appreciated; thumbs up!

Good to know for Swiss Customer (import costs)

I have purchased a Woom 4 Off.
I had to pay - apart from the custom import fee (c.ca 70 CHF) - the transport company mgmt. fee of 95 CHF.

I paid the bike 580 EUR + 99 EUR shipment.
Custom fee+mgmt. fee=162 CHF.

For customer requiring import to Switzerland, a simple advice: take into account the import costs when calculating the total.
