Re:
Saw this thread earlier in the week but didn't have the time/energy to respond. A couple of points:
1) I understand that ebike sales in the UK increased from 60,000 units last year to around 100,000 so this year: a 67% uplift. That indicates that demand is outstripping supply: prices are likely to be high. It's too quick for producers to expand their manufacturing capacity (especially in this year's circumstances) to achieve greater economies of scale: that will tend to keep prices relatively high. Furthermore, it will take longer for new entrants to the market to arrive, introduce more competition and drive prices down. In short, the ebike market is out of equilibrium, immature if it's growing rapidly and, yes, there probably are excess profits being made. In other words, basic economics applies. It might be a frustrating time for buyers but probably for sellers too: in other circumstances, they could both increase profits and lower prices. A canny, 'prieswert' Scot has probably benefited when the reverse applies and sellers have lost out so, although the frustration is understandable, this is just the flip side of a market economy.
2) You might have considered and rejected this idea already but wouldn't an ebike conversion kit for a bike you already have be a sensible solution. My concern with a dedicated ebike would be focused on when the battery reaches end of life. Will the batteries still be available and will producers, effectively, have monopolies on batteries that only fit their bikes due to a lack of industry standards. If so, you would be stuck in a similar situation again, frustrated by a market that isn't functioning well for consumers. A conversion kit is not as elegant but would alleviate that risk.
