Do you need technical assistance?

If so your first point of contact and fastest way to resolve any issues is through the shop where you purchased the bike, even if this was on-line.

If you need to arrange a service for your Wisper ebike, or need technical assistance, your first point of contact is always with your local Wisper Dealer, even if you bought your bike on-line.  In nearly all cases they will be able to arrange a service or resolve any issue you may have with your bike quickly and efficiently. They will be pleased to hear from you and are best placed to look after you.

If they can’t resolve an issue, they will call our service department for assistance. We have many years experience and hold thousands of spare parts in our warehouse in Kent and in most cases can despatch the exact part you need within 24 hours. Uniquely in the ebike business, we at Wisper support our bikes up to and often more than seven years from new.

If your local Wisper Dealer is unable to offer the assistance you require, you are welcome to contact us by email support@wisperbikes.com and one of our tech experts will get back to you. In most cases they will refer you to your original supplier and liaise with them in order to assist you. Whatever the situation we will make absolutely sure you are looked after in the most efficient manner possible.
