I contacted
electricbikeconversions as I liked the fact that they are very close to where I live. They didn't respond via a mail sent from their web site so I rang them. The guy I spoke to was very open and friendly over the phone.
I had decided t(after much research) hat a Mid Drive motor was what I wanted, I have read quite a lot about problems with the wheels and loose spokes on hub motors so decided I wanted to avoid that. They still list a
250W kit (10 in stock) on their web site at £550 'with a 13A' (sic) battery.
I was told they actually only had two 'old' kits in stock which did not have any throttle function and it could not be added. Further they were discontinuing the mid drive units as they had been
'less successful than the hub drives'. Clearly support down the line was likely to be a problem so I decided to shop elsewhere.
I accept the 'start-up' nature of the e-bike industry, especially the conversion kit market, but you would hope they could at least keep the web site up to date.
I still may use them if I decide to convert my wife's bike, as a front motor/rack mount battery will suit her bike, but that can wait until next year.
