I'd bet that you WOULD pay that $5000,..... IF, you had an income that allowed you to!!! Nobody wants something cheap, if they can afford otherwise. And many would pay extra for convenience too,.... IF, they can afford to do so. Patriotism is relative to home and family. Even if you personally worked at the Bosh factory in your own home town and got a 20% discount, with above average income.... you would still only buy from Bosh if you could afford to do so, otherwise, your still jus gonna buy that $3000 Chinese special!!!
I believe the last motor I ordered direct from China a couple years ago, was subject to a 6% tariff that was included in those "high shipping costs", so often complained of. Many imports are subject to tariffs already and have been for decades,... one of the many reasons I am no longer a craftsman of leather items and accessories (rather shocking that in a country that produces so much beef and pork for domestic and export, and yet you could count the domestic tanneries on one hand with fingers missing!). The high shipping costs of imports in general, offsets high tariffs on many items while still keeping a low overall expense with few exceptions. "Most folks will hardly notice!",.... sound familiar.

Yes,... your high shipping costs helps pay tariffs on luxury items you probably can't afford!
While many are watching for the effects of tariffs on technology (motors, controllers, electronics, etc.), you likely haven't noticed other things, like STEEL!!!! I'm a bit ticked at domestic steel that has bitched about low cost imports, and now with high tariffs they raise their domestic prices, making ALL steel more expensive,... domestic or not!!! And you know damn well these prices for both will never come back down with or without tariffs!!! "Trade wars are easy to win!",... sound familiar again. Yup,... the winners are domestic and foreign corporations, and consumers seldom see any great slice of that pie!!! As a corporate employee,... you can only hope to see some scraps of the crust to enjoy.
Yes, prices of e-bikes WILL rise,.... with or without tariffs. 25%??? Maybe,... and when all has ended, we might see prices drop 10-15%!!! Which is 10-15% higher than WITHOUT this tariff battle!!!
But WTH!!! Average income has increased, right??? :? Well, for China anyways.
