The current crossfire is better than the previous model. It now has a complete Suntour powertrain with no mixing and matching of components and appears more reliable. Battery capacity is decent too. Whether its a nice bike to ride dynamically is another matter. Not my cup of tea to ride, but that is much a taste thing as anything else.
Carrera ebikes have a bad rep on these pages, some of it perhaps deserved, much of it definitely not. However, Halfords modestly claim they have sold more Carrera ebikes in the UK than every other brand combined. Nevetheless, if you go back through the pages of this forum looking and threads from people that are having problems the majority will be from other makes, despite these other makes being far, far less common, which is rather counter to the supposed wisdom that some commentators trot out. Go back through these pages and see that for yourself, rahter than listen to mere opinion.
Leaving aside it doesn't suit my riding style, I would have no qualms with the Crossfire. I recently apent some time with the 2020 Subway Electric and thoroughly enjoyed it so is worthy of consideration, although that has a lesser battery capacity so assisted range will be less in comparison.
Alas, I have no experience of the Raleigh so can not advise.
