Stu....in an ideal world we would all have a national chain who would have a sample of every bike from every marque they advertise for sale.
Unfortunately there is just not a big enough market in the UK for that to be possible,this is in contrast to Germany which has a market some 20 times that of the U.K.,every decent size town has a bike shop which will have a good display of electric bikes.
One of the other problems is the Brits seem not to want to spend much more than £1k,especially on their first e-bike. It is difficult to balance the need to give a dealer a profit,the importer a profit,provide a nice bike and keep the package at less than £1k. Many dealers won't work with low profit margins,I can't blame them with the cost of running a retail bike shop in the UK,so they tend to stock and sell higher value bikes which have the headroom to develop higher margins.
There are some internet sellers who are internet only sale,it is easier to work under the £1k limit because you don't have to allow the dealer margin but you have to take the risk of buying a bike unridden.
In Holland there is a massive market for cheap step thrus bought on the internet but the Dutch are not so fashion conscious about their bikes,they know that a certain size/spec is what they want and the only choice is about colour.
They say there is no such thing as a free lunch,if you want dealer support then it's not unreasonable that the dealer makes a profit,if you are prepared to take a bit of a gamble you can buy cheaper off the internet.
The distant selling regs require a cooling off period that gives you the opportunity to return something you don't like or say doesn't fit,but these bikes are expensive to move around so it seems fair that if a supplier sends the bike out free carriage,you pay the return carriage cost if you change your mind. The bike must be returned in new condition in original packing,so always keep the box,in the spirit of being fair most suppliers will accept the tyres have some use and a bit of cleaning on return.
If the market was bigger in the UK it would all be so much easier but we all have to accept that is where it is.
Hope the info is useful.
