That’s actually a really good question and the truth is, there’s not one answer.
Put it this way though, the way I often put it to people is, what you think you’ll save if you believe the marketing, prepare yourself for a massive disappointment as it’s not as much as people are lured into thinking.
20p or so a cycle, save 20-40{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} at best with a fair wind and sunny skies if the truths hold, it’s really not enough to get excited about. Even if it were a £1 a cycle you need to do an awful lot to cover the cost or a replacement.
