My Crossfire is over 3 yrs old now. It’s had the cutting out issue from day 1, tho Halfords have always denied there is an ongoing problem.
They’ve given a variety of excuses – overheating (even first thing on a cold, frosty morning!), poor connections (which they claim they fixed), and water getting into the display or contacts (so my fault for riding it in wet weather!!).
Another excuse is that are they are too busy to see me – come back in the few months, when they might have availability! And they have since closed their Bath store, saying I now need to take it to Bristol or Trowbridge. The trouble is, when you take it in, they need it for the day, at least, leaving you stranded without transport, so I’ve just learned to grin and bear it, even tho it is inconvenient and sometimes downright dangerous...
I actually put a review about the Crossfire problems on the Halfords website – they immediately took it down, saying it didn’t comply with their regulations!!
