Yes, ....My electric assist trike was about $5,000.
Roughly 25 years ago I paid the equivalent of about $600 but our dollar was trading close to par back then, for an inferior product (lead-acid gel cells, heavier steel frame, etc).
Today, most ebikes are lighter due to the energy storage medium (litium-ion or lithium polymer), lighter frame (less payload == less steel), aluminum wheels, etc. At today’s exchange rate it would set me back about USD$2,000. Trikes probably cost more due to higher shipping costs necessitated by the increased weight (~150-200%) so you probably paid about the same.
After all, it’s ultimately about Value. Like Beauty, it is in the Eye of the Beholder.
