Frequently Asked Questions

We Ship All Bikes Partially Disassembled in A Heavyweight Carton, Via UPS or FEDEX GROUND In the Lower 48. See Our Full Shipping Policy Here

We Remove the Front Wheel and Handlebars to Ship. The Headlamp, Pedals and Seat Must Be Installed, As Well As Any Accessories. You Are Welcome to Do the Assembly Yourself With the Assistance of Our Virtual Manual And Provided Tools.  The Assembly Time is Typically 45-60 Minutes.  If For Any Reason You are Not Comfortable or Capable of Performing the Assembly, We Recommend Contacting Your Local Bike Shop or A Mobile Bicycle Repair Service to Perform the Assembly For You.  One of the Benefits of Choosing Such a Service Is They May Perform Maintenance on Your Bike Throughout It's Lifecycle. This Will Give Them an Opportunity to Get Familiar With Your New Bike.  

All Wicked Thumb Bikes Come Standard With 26X4 Fat Tires. All Versions (Street, Sand and Whitewall) Have a Maximum Tire Pressure Rating of 20 PSI. If You Go A Little Less (15 PSI), The Ride Softens Up At the Expense of Softer Cornering. At 20 PSI You'll Get Maximum Firmness and Speed on A Hard Surface. For Sand Riding You May Decide to Go Lower (10-15PSI) For More Traction. We Don't Recommend Anything Lower than 10 PSI.  Each Rider is Different and Has Different Preferences, So Experiment to Your Likeness.   Just Do Not Overinflate as the Tube May Burst or the Tire May Pop Off the Bead. When the Weather is Colder, Your Tire Pressure Will Drop, So Make Sure to Check during the Winter Months.  Do the Same If You Bring Your Bike to High Altitude.  

The Whitewall and Black Street Tire Are the Same Tire, Just Different Color. If You're Doing Mostly Road, Path, Sidewalk and Hard Pack Surface Riding, We Suggest the Street Tires.  If You Will Predominantly Ride on Sand, Gravel, Snow and Rough Terrain, We Suggest the Sand Tire. Each Tire Will Perform Better on It's Respective Terrain, Yet Both Can Be Used on All Terrains.  The Sand Tire Will be Noisier at Speed and May Be A Little Slower at Top Speed. For the All-Season, All Terrain Rider, You Can Buy a Set of Both and Switch Them Out as You See Fit.

Absolutely Not!  We Have Quite a Few Bad Ass Ladies Riding Custom Destroyers, with Everything From Ape Hangers to Custom Paint Jobs, including lots of Couples.  You know What They Say - What's Good for the Goose... 

The Destroyer is A Substantial Bike, But the Standover Height is Good for Someone 5'3" or Taller and We are Happy to Cut the Seat Down if You Wish. Our Recommended Rider Height for the Stock Bike is 5'3" to 6'2”. But We Can Easily Configure the Bike With a Cutdown Seat for Someone 5'1 or Taller and Ape Hangers for Riders Up to 6'6".  The Throttle Makes It Easy to Get the Bike Going Without Pedal Power.

Any noises from your bike should be diagnosed and resolved as soon as possible. It is common for noises to pop up and they are a notification to you that something is out of alignment, loose or being overexerted.

One of the more common noises will be a squeal or grind from your brakes.  This is most commonly due to misalignment of the caliper, a bent rotor, or worn or soiled pads.  

To Align your brakes, Loosen the two allen bolts that attach the caliper to the caliper bracket (do not loosen the caliper bracket). Raise the wheel off the ground and spin it.  Apply the brake for that wheel until it stops the wheel.  Hold the brake lever down tight while tightening the caliper bolts.  Do the same for the other wheel.  This will typically resolve the issue on a new bike.  .  

A buzzing from the tank or rear hub motor will indicate the controller and motor are being overexerted. this can lead to failure of the controller and motor if prolonged. Buzzing from the controller is a sign of too much strain on the electrical drive system

Causes for this can be:

  • Overexerting the motor on a hot day.  

  • Underinflated tires (check to make sure tires are at least 15 psi on street)

  • Trying to climb a hill with throttle only (always help the bike by pedaling when climbing.  Every bit of pedaling greatly improves motor function)

  • There is too much weight on the bike

  • The battery level is low and you are trying to push the bike too hard ( do not go open throttle on a low battery )

  • Please read this blog post on battery life as it pertains to overall electric drive system longevity

Most maintenance on your bike can be performed by your local bike shop. if you currently maintain your own bicycle or e-bike, then most maintenance will be second nature. the most common maintenance items will be:

  • Brake pad inspection and change
  • Tire pressure maintenance
  • Tires / tubes inspection and changes
  • Spoke inspection and tightening
  • Brake alignment/caliper position adjustment
  • Bent rotor replacement
  • Chain inspection and replacement
  • Headset adjustment
  • Battery replacement for led tail light
  • Hand grip replacement
  • Derailleur adjustment
  • Electrical system maintenance should be performed by a reputable shop or sent to Wicked Thumb directly for replacement

Due to the speed and power of the bike, we strongly suggest taking it to your local bike shop or mobile bicycle mechanic for inspection and maintenance at least once a year.  If you ride alot more often and/or year round, seasonally may be a better schedule for you. Ultimately you and your bike are not cheap and the safety of the rider and longevity of your investment are directly affected by how regularly you maintain the working parts.
