carrera crossfire no assist

It sounds like there's a separate torque sensor then. That could be the source of the problem. I wonder where it is and what type? There must be more under that cover.

Many Chinese ebikes around £1,000 suffer from niggly electrical faults.

In terms of what you do next, the first thing you need to do is accept the above, so there's no point in buying another £1,000 ebike because your experience will likely repeat itself.

If you can spend closer to £2,000, you could get something that has a very good chance of being reliable.

And if you buy from a supplier in this country who stock spare parts and can help as well that helps as well.

...thinking back the bike kept cutting out a lot taking the battery at least 4 times on a 3 mile journey and putting back in started then 100 yds faded again .

That's a totally different problem with this specific e-bike, mentioned on a few threads here, but well documented on Halfords own site. It seems the battery jiggles around a little in its' bracket breaking connections - using a strap or Velcro pads to hold it firmly appears to stop that.

Back to Halfords? As one of Halfords most popular models, they must know this particular e-bike and its common problems inside out.

That's different then. You should have mentioned that before. You need to solve this step by step starting with the battery. You need a voltmeter. if you haven't got one, you need to get one. You can't do anything without one.

Charge up the battery, take it off the bike and measure the voltage on the terminals. Can you show some photos of the terminals and the charge socket?

Or you could spend £500 on a Chinese bike and get one that's totally reliable.

You could spend £2 on a Lotto ticket and win millions.

In terms of probability, there's probably not much in it.

Edit: Speaking of niggly faults, the software seems to be producing random quoted posts in this thread.

just letting you know my carrera has been fixed by halfords in hull. the bike was not under warranty m being the second owner,the problem was inside was all corroded new one fitted took about 3 weeks running very nice.

 

[cyclebuddy]

Your earlier photos did show some rust and corrosion, which did seem a bit unusual given the bike was only 6 months old. Glad to hear you bike is now fixed.
