Determining Where the Buzzing is Coming From
The first thing you need to do is determine which component is causing the noise. This is most easily done with a bike stand, but if you don't have one, you can tip the bike onto the kickstand.
Check the rear fender. Before you do anything else, make sure that the fender isn't bent and touching the tire. Spin the wheel and check to see if any part of the fender is touching the tire. If so, then simply bend it out of the way and see if the buzzing goes away. If not, let's move onto the next step.
Put your hand on the rear fender. We're going to put our hand onto three specific parts of the fender to hold it in place. Please make sure that you keep your fingers away from the wheel. We'll be spinning up the wheel so you definitely don't want your fingers to get caught.
- First, place your hand on top of the fender near the bolts that hold the fender-stay on the fender itself. Using the throttle, spin up the wheel. Take note if the buzzing goes away.
- Secondly, carefully place your hand on the fender-stay arms down near the frame, there are two of them so be sure to check both sides. Using the throttle, spin up the wheel. Take note if the buzzing goes away.
- Finally, place your hand on the side of the fender down near the crank. Spin up the wheel once again and see if the buzzing goes away.
Check the rear light. If the buzzing doesn't go away, then we need to check the rear light.
- Grip the Rear Light with your hand and spin up the wheel. Take note if the buzzing goes away.
Check the rear caliper. If the buzzing still hasn't gone away, let's check the rear caliper.
- Once again, be sure to keep your hand away from the spokes of the wheel. They definitely hurt when the wheel is spinning.
- Carefully grip the rear caliper and spin up the wheel. Take note if the buzzing goes away.
Fixing the Buzzing
Once you've determined what is causing the buzzing, all you need to do is tighten the right bolts.
Depending on what you've determined during the testing, we'll need to tighten the bolts in one of three places. Of course it's totally fine to tighten all three if you want to be sure.
- Let's tighten the bolts on top of the fender. Grab your allen wrench and tighten them up.
- Next, let's tighten the bolts on the fender-stay arms down near the frame. Be sure to tighten both sides.
- Finally, let's tighten the bolts on the side of the fender down near the crank.
If the buzzing was coming from the rear light, simply tighten the bolts on the casing of the light.
If the buzzing was coming from the rear caliper, simply tighten the bolts on the rear caliper.
That's it! You should now be able to ride your Euphree electric bike without any buzzing noises. If you have any further questions, please don't hesitate to contact us.
