At Triton Cycles we aim to provide a returns service that is simple and hassle-free.

Should you need to return anything to us, it is very important that you telephone us first to advise us of your intention and the reason why you wish to return the goods. If you're not completely satisfied with an item you may return it within 14 days of purchase, and as long as the item isn't fitted or used we're happy to receive it back for a refund or exchange. Return shipping costs in this instance are non-refundable.

If the item is being returned as a result of our error i.e. damaged, defective, wrong item sent etc, we will refund Royal Mail First Class or Standard Parcel postage costs. If this is the case please include a copy of your purchase receipt when you return the goods for inspection. Please DO NOT sign for goods if you think that they are damaged, or the packaging has been tampered with. Instead, refuse to accept the delivery and contact us immediately(within 3 working days) so that we can take the matter up with our courier. Replacements will be sent to you as soon as possible. Signing for goods later found to be unacceptably damaged in transit complicates negotiations with the courier in dealing with your complaint. However, if a minor component is missing or broken(e.g. a reflector) please DO NOT return the whole bike. Simply contact us and we will replace the part as soon as possible. Please DO NOT discard any original packaging until you are fully satisfied with your purchase. Should you need to return a bicycle, couriers will not transport a machine not in the original or suitable packaging. Warranty Claims: All goods purchased from Triton are covered by a full warranty and generally covers manufacturing faults and defects including poor workmanship. If you think your item is faulty and would like to make a warranty claim then please phone/email us before returning any goods - we may be able to solve your problem without you incurring any postage costs.

All purchases and refunds will be processed in Sterling (GBP). We are not liable for any currency fluctuations. Please be aware that this may result in your refund being less or more than what you originally paid in your local currency.

The delivery charge for any international orders returned due to unpaid customs and duties charges will not be refunded. Please note that for international returns the return shipping and any reverse duties & taxes are the responsibility of the customer.
