Occasionally, after assembly or after riding, a whining, whistling, or squeaking noise may be heard coming from the front wheel. This is almost always resolved by applying some low-weight lubricant or grease to the areas of the bike shown below. An example lubricant would be chain lube oil you may already have. A few drops carefully placed just inside the seal will likely resolve the issue. It is easy to apply; just be sure to avoid getting any on the brake rotor. There is a dust cap cover on both sides of the wheel, be sure to apply it to both.
Again, be sure not to get grease or any lubricant on the brake rotor. Avoid touching the brake rotor with fingers. The oil can contaminate it and cause a completely different noise - check Brake Noise Article.
In some instances, if the noise persists, it will be best to remove the front wheel and even slide the dust cover off, as shown in the 3rd and 4th picture below, to apply grease. If this does not resolve the issue, please contact support: https://ride1up.com/contact/
