Got questions?

ALL Prevelo bikes have hand brakes.  The Alpha One also has a coaster brake, which can be removed with our freewheel kit.

Alpha Zero:  rear hand brake only

Alpha One and Zulu One:  front and rear hand brakes + coaster brake (removable with freewheel kit)

Alpha Two, Alpha Three, Alpha Four, Zulu Two, Zulu Three, and Zulu Four:  front and rear hand brakes (no coaster brakes)

We believe that the best way to teach children to ride is to prioritize teaching balance.  Balance is the most difficult part of learning to ride a bike and the skill that training wheels are poor at teaching.

We do not offer training wheels for our bikes.  And because of the design of the rear drop out on Prevelo Bikes (where the rear wheel attaches to the bike), it would be challenging to fit training wheels on our bikes

Our recommended teaching method is to let children learn balance by practicing without the pedals on that bike (so the child is running with the bike underneath them).  After some time doing this, your child should learn to coast for short distance by sitting in the seat and lifting her feet off the ground.

Prevelo bikes come almost fully assembled.  Here are the complete assembly requirements for each bike:

Alpha Zero:  (1) attach handlebar to stem and (2) adjust seat height

Alpha One, Alpha Two, Zulu One and Zulu Two: (1) attach handlebar to stem, (2) attach pedals and (3) adjust seat height

Alpha Three, Alpha Four, Zulu Three and Zulu Four:    (1) attach handlebar to stem, (2) attach front wheels, (3) attach pedals and (4) adjust seat height

You can find instructions for operating the Presta valve on the Zulu Series tires at the bottom of the tire pressure guide page.

In order to remove the coaster brake you need to have the Alpha One Freewheel Kit.  If you would like to purchase a freewheel kit for the Alpha One, you can either check the box to include it with your Alpha One purchase, or you can buy it separately here: Alpha One Freewheel Kit

To remove the coaster brake and install the freewheel kit, please see the Freewheel Kit Installation Instructions

Please view our kickstand installation instructions here:   

NOTE: If you order a bike and a kickstand in the same order, the kickstand will come installed on the bike. These instructions are for customers who purchased the bike and kickstand separately.

If the brake rub is slight, it will likely go away over time as the brake pads wear and the brake cable stretches.  But if the brake rub is severe, or if you would like to try to perfectly tune the front wheel so there is no brake rub, please view the instructions here:

If the front end of the bike feels loose or wobbly inside of the head tube, the most likely culprit is a loose headset.  Tightening the headset is simple and only takes a minute.

If your handlebar is not lined up with the front wheel on your bike, follow the instructions here to straighten it out:  LINK
Please see the video here for tips on adjusting and troubleshooting v-brakes (rim brakes).

The HEIR 16 fork will fit on the Zulu Two.  But there are a couple of caveats to be aware of:

  1. The Zulu Two (standard) and Zulu Two HEIR frames are not identical.  The Zulu Two HEIR frame's headtube angle is adjusted to correct for the longer fork.  If you put an HEIR 16 fork on a Zulu Two (standard), it will slacken the head tube angle.
  2. You will need a 160mm brake rotor for the front.

You can purchase the HEIR 16 fork here: HEIR Fork

Service instructions for the HEIR fork can be found here: HEIR Fork Service Guide

The brake levers on Radius hydraulic brakes found on Zulu Series bikes are reach adjustable.  See instructions here:  Adjusting reach on Radius hydraulic brake levers

United States CPSC standards require the Alpha One to be shipped with a coaster brake installed. A coaster brake is the type of brake the is operated by pedaling backwards.  Many parents/riders prefer to a bike without a coaster brake.  The freewheel kit allows the removal of the coaster brake and installation of a freewheel. It includes a complete extra wheel with a freewheel hub, tire and tube. Requires Installation.

Like most brands Prevelo bikes are made in Asia (specifically, Prevelo bikes are made in Taiwan, Cambodia and Thailand).  The ownership, product development, marketing, graphics design, web design, and pretty much everything else, is done right here in the United States.  When you buy a Prevelo bike, some of the money goes to Asia for manufacturing costs (like most brands).  The rest stays in the United States.


Here are the approximate shipping weights and dimensions of each bike.  Note that there are some variance in weight, particularly if accessories are added:

Refunds are always processed onto the card that you used to purchase the order that is being refunded.  If you purchased with a gift card such as a Visa or American Express gift card, the funds will go back onto that gift card.  If the payment method used to make the purchase has been cancelled (for example, if you closed a credit card account after making the purchase) you will need to contact your bank to see about receiving the money that is refunded.

The one exception to this rule is for Trade-Up Club returns.  With Trade-Up Club returns the credit for the old bike is refunded to the payment method used for the new bike.
