Finding my (electric) wheels

Hi everyone,
My husband has this bike and, there is a constant creak from the handlebar area.
The bike shop stripped the front down, looked at the flexible stem, rebuilt the bike and, it's still there.
Suggestions would be welcome.

also the back wheel cheeps (constantly).
Spokes have been checked.
The brakes checked.
No chaffing on the mudguards?
Again, suggestions are welcome.

lastly, does anyone else see two bars of battery left but, its dead
The bike has done 350 miles and had a check over service and a full strip down service last week.
Many thanks in advance.

There are cyclic load changes at the bars every pedal stroke as the arm forces change to balance the pedal forces. Anything with the ability to move will, and low level noises will be the result.

It should be possible to reproduce the noise when stationary, possibly needing a second person's assistance. Try pulling up on one grip whilst pushing down on the other, then reverse the directions, repeatedly.

My leading suspects would be anything a bit different to a run of the mill handlebar area, which would have me looking in great detail at the flexible stem.

The cheaping from the back is probably the disc touching the caliper. You can determine that by holding on the brake slightly to see if the noise changes. If that's what it is, loosen the two screws that hold the caliper to the adapter, hold the brake on hard and retighten the screws while holding. I have seen on some bikes, where the brake caliper is a bit low, the cheaping only comes after you apply the brake because the heat makes the disc expand enough to touch then it stops touching when it cools down and shrinks. In that case, you solve it with a washer to lift the caliper a bit. It's not likely to get that problem on an OEM bike, though.
