You mentioned filling up the air wasn’t this bike assembled by Walmart because if it’s was that should have been done already. Next idea is you don’t mention charging the battery it’s generally shipped with almost no charge maybe enough to turn it on and check the settings so it needs a full charge which usually takes at least a few hours sometimes overnight if it’s a large capacity battery. I do bike building for Target and the reason we don’t assemble the e-bikes is that the charging is required to fully test that everything is adjusted properly especially the brake sensors and the pedal assist. On top of that test rides of all bikes are conducted inside the warehouse of our store and having the motor kick in while riding on a painted concrete floor would be dangerous so corporate decided that we would instruct guests to take them to a bike shop for the assembly. We’re not allowed to use outside to test bikes for obvious reasons insurance doesn’t cover employees working outside the store and then tires will appear used not new. I highly doubt Walmart builds the e-bikes either because the charging takes a long time. If you’re near the Chicago area I’m an avid e-bike rider and I can offer my assistance to check it out no charge if it’s not far from me or you can bring it to me but it will need a fully charged battery.
