I wonder if anyone can help ? I know that Wisper have a good reputation on here but it appears that there has been a change in ownership and the brand is now owned by Da Forza Ltd and they don’t seem to be responding to any customers who bought bikes prior to the transfer of the brand. I have serious issues with a bike that was delivered in October 2025 and which has done only 24 miles due to defects and issues. Despite assurances that these would be addressed there has been no response from them since December 2025. Has anyone had any luck with the new Company honouring warranty issues with bikes previously supplied by the old Company ?
