I own a Salisbury (the blokes version of the Windsor) and still ride it for shorter journey when I want something a bit less powerful than the Wisper and not to have to be so paranoid about theft (as it doesn't look as flash).
TBH the Infineum was a missed opportunity for them, it has taken so long to sort out the issues, IMO they would have been better off making a 36V version of the Salisbury rather than inventing a whole new bike...
this and problems with reliability on their other bikes also overloaded their customer service / support resources which appear to be shared rather thinly between all the other companies in the Akther group.
After a good start, the management also seemed to actively discourage their staff from participating in these forums, perhaps because it diverted them from a workload dealing with other issues and encouraged publicity over problems, especially when they suffered a drop in profits one half-year (which they appear to have recovered from).
Akther group do still sell the computers, and it appears the Salisbury / Windsor (which can be found on considerable discounts) are still good bikes if you get a decent one, and they appear to have become a bit better at customer service recently.
One caveat though about these diversified businesses (unlike a company solely making e-bikes) is that customer service resources and good people follow the money and the markets - they can be diverted to other more profitable business lines as bikes are only part of the business.
