Pre-Order Dates

We do not open pre-orders for a shipment until we have a good amount of confidence in the ship date.  That being said, the estimated delivery dates listed on our website are based on the best information that we have at the moment.  While we cannot control every variable, we pledge to be honest and transparent about lead times.

- The ship dates that are on the website represent our honest estimate of the date that the bikes will ship on.

- Where information is imprecise (for example, referencing a month or quarter), it is because there are unpredictable factors that make it so we cannot credibly be more precise.

- We will work tirelessly to keep the bikes on schedule. It's part of our company culture to be very involved in our supply chain and to be proactive about addressing issues that could turn into delays.

- If something happens that changes the ship date we will communicate quickly and clearly about the delay.

- You can cancel your pre-order any time before your bike ships.


Pre-date changes

Your pre-order date will be included in your order confirmation. If we learn something that changes that date, we will contact you. You might see the pre-order date change on the website. There are a variety of things that could cause a change in the pre-order date including shipping delays, back logs, or moving through different batches. Just because the date on the website changes, does not mean that the date of a pre-order already placed has changed.  Again, if you place a pre-order and the estimated delivery date changes, we will inform you.


Pre-order payment policy

Your credit card will be charged immediately when you place your pre-order.  Your pre-order is cancelable and fully refundable. If you need to cancel a pre-order contact us and we'll take care of it!

Durable Rear Stays and Rear V-Brake

Kids are going to put their bikes through the ringer, so the Alpha Zero is built kid tough with robust rear stays. And the v-brake lets riders start learning braking right at the beginning.

Quick Adjust Seat Height

The quick-release seat post clamp makes it easy to adjust the seat height without tools.

Kid Friendly Hubs

The hubs feature allen head skewers that are strong, easy to use, and have smooth edges. Additionally, since children will often ride their bikes through mud, the hubs are equipped with seal cartridge bearings to keep out dirt and grime, ensuring smoother operation and longevity.

Integrated Handlebar and Stem

The Alpha Zero features a one-piece handlebar and stem combo that keeps weight low and design clean. It’s shaped specifically for young riders, with a slim 19 mm diameter grip and short reach for easy control. All bolts are recessed, and the stem has a rounded profile, so there are no sharp edges or exposed hardware for knees to catch on. Thoughtfully engineered for both comfort and safety.

The Beginning.

Two Wheeling Tots

My little guy's 18 months and just figured this bike out...He's already decided he's a mountain biker and loves heading out on the Prevelo Alpha Zero on the little dirt path behind our house and lifting his front wheel over roots on the trail

Pinkbike

Little ones with a penchant for adventure will love the sturdy ride of Prevelo’s Alpha Zero. Built with high end components like Tektro brakes, a threadless headset for more secure handlebar alignment, and a lightweight aluminum frame, it offers a supremely smooth ride whether they’re hitting the pavement or a wooded trail.

Motherly

The confidence on display in my son’s riding is undoubtedly due to the design and geometry of the Prevelo Alpha Zero. Its handling and quality build has set him up perfectly to progress onto a pedal bike.
