Besides demo events and visiting SPOT, is there any other way I can test ride a bike?

Yes, there is another option but it requires that the bike is purchased first. You can buy the bike and ride it for 30 days. If you decide it's not for you, we'll take it back for a refund minus 10% if it's used. This is almost like a trial period or the ability to demo the bike with the cost being 10% of the price. So, if it doesn't work out you have options and if it does, you have a bike ;).
