You've asked a decent question and made a reasonable point, so I'll repond
I honestly don't think it'll have a massively negative impact on my business. I'm comfortable our business model can adapt and the way we work will mean we continue to take market share from the big players in the UK. We can survive at a smaller size than we currently are, but I expect us to continue to grow as the bigger players who aren't as flexible and work on tighter margins have different and possibly more challenging issues.
The negative impact it will have I know about though my work in a few fields. currently import. So the reason I'm fairly comfortable that it won't impact my company too strongly is that I know the negative effects will effect all our imports. If we leave the single market that will mean everything we currently buy being sat in customers for clearance, having a handling fee charged and taking longer to get to market. This means the end consumer will pay more, even without a tariff or without continued decline in the value of the £.
So the country will be worse off with no matching pay rise at the same time.
This will decrease spending power and increase inflation. With no real benefit to the economy.
We'll still sell bikes because the type of people we sell to are generally enthusiasts or commuters. Both of these type of people need bikes, they might cut back on the price a bit, or maybe not replace their bike as often, but cyclists are cyclists... they'll cut back on lots of things before they give up on their bikes.
As for what I think the outcome will be, well honestly, I've spoken to a number of MPs and met with a Lord personally. I think Trump is the best thing that could have happened for remain campaigners. He's now giving a first hand demonstration of what a nationist, right wing, protectionist world can look like, he's also showing that scapegoating doesn't work.
I hope that A50 gets triggered, the pain starts to kick in, and people suffer, me included. I think this is needed so that people can see that we've actually been doing pretty well inside the EU, and unemployment is low, interest rates are low and we have cheap food and clothes etc etc. Our universities are boosting many poor urban areas and growing because of increased attendance from foreign students. There are lots and lots of problems in the UK, and I'm not trying to push them under the carpet, but I think they are solved by many many things that can be done by the UK and isn't being prevented by the EU. Blaming the EU for everything doesn't help anyone, apart from those that are hiding from the blame.
I think the departure of the main players in the Leave campaign tells us everything. Leave has sold a dream or a promise of a better life, which isn't possible, I suspect. I hope it is, but literally every expert I've spoken to in every field has said its a bad idea.
I'd love to be wrong, and as I've said before if you can give me things to be positive about, I'll happily change my views. But its been getting on for a year now, and still nothing sensible I'm afraid.
