Loaded with Features Obsessively Thought Out for Kids

Kid Optimized Crank

Prevelo crank lengths are custom sized for each size bike to make sure little riders have optimum pedal ergonomics. And they have ultra-narrow Q-factors to match the narrow hips of young cyclists. If that sounds like technical mumbo jumbo, here's the point - Prevelo cranks will help make small riders more comfortable and efficient on their bike.

Confidence Inspiring Trail Geometry

The Zulu Three features Prevelo's signature confidence inspiring geometry. Prevelo geometry utilizes a low bottom bracket that lowers the center of gravity of the bike and rider, making for a more agile and confident ride. The slack front end makes the bike forgiving to young trail riders experimenting with tough terrain.

Microshift Advent Super Short Drivetrain

The Zulu Three features the new Microshift Advent Super Short derailleur. The super short cage provides ample ground clearance for small wheels, while simultaneously providing best in class gear range. The clutch helps minimize chain drop while still providing crisp, accurate shifts.

Tubeless Ready Tires and Rims

All Zulu Threes are equipped with tubeless ready tires and rims, so you can ditch the tube, reduce flats, and get a more comfortable grippier ride. Bikes ship with tubes installed and will need to be setup tubeless by you or your mechanic.

Zulu Standard - Go-Go Grey

Fast, rugged, lean, and made with a special Go-Go Juice* formula designed to intimidate your opponents into submission as they smell the dirt kicked up by your tires.
* Contains 0% Go-Go Juice

Zulu HEIR - Battlestar Black

Formulated with particles that harness the power of the nearest star. Designed by Earthlings and tested primarily with the closest available star, a Class G2V star known as the Sun. Not tested with Class O stars - do not ride within 2 light years of a Class O star.

    Genuine Personalized Customer Service

    We pre-ordered a Zulu Three for our 7 year old son in November. As the estimated arrival would be after December 25th, Prevelo offered to send a customized “official riders license” and Prevelo jersey so we had something for him to open on Christmas Day. The thing if it was, I had missed this option when ordering the bike. I sent an email to customer service to inquire and received an immediate personalized response. To top it off, my sons riders license liklly was accidentally thrown out with the wrapping paper. My son was bummed about loosing his license so I reached out again to see if I could pay for a new one. To my surprise…Prevelo immediately sent out a new licenses at no charge. You may have noticed that I’ve yet to comment on the bike. Yes, it is awesome and my son loves it as we were expecting. What is truly surprising is the genuine personalized serviced we received from Jim and Owen. Thank you gentlemen!

    Just amazing!

    This is my sons second Zulu and he loves this one even more than the last. He rides it everywhere, local trails and even to the shops he just doesn’t want to ride anything else! When you see the bikes in person, the attention to detail is really amazing, and for the level of quality you are getting I think the price is very fair. If your little one loves the trails, don’t think twice, get a Zulu. The countless hours of fun and memories you’ll have together is so worth it!

    Worth every penny and the wait!!

    We cannot recommend Prevelo enough!! This bike is fantastic. Simple to put together out of the box and it was already set up. The gearing.... The disc brakes... the light weight.... the color... I could go on. I get tears in my eyes thinking about how awesome this bike is. And my son's love for it abounds!! It fits him now and room for growth.

    Super Sweet Li'l Rippers Ride

    I bought this for our six year old son who's an advanced mountain biker for his age. He loves this bike. It fits him perfectly (48" tall and about 45 lbs) and you've done a great job to keep the weight down to a respectable level which is key for him since he doesn't weigh too much. The geometry and frame design is fantastic and largely why I chose the Zulu Three Heir. His inaugural rides on it were in Sedona for the week over Spring Break which allowed him to ride on a variety of conditions - from buff, flowy loam to sweet technical ledges, drops, etc and everything in between (think Slim Shady, Templeton, Easy Breezy). The rake of the bike is outstanding. He was able to roll some large drops that he couldn't jump that I wasn't sure would be makeable for him. And, for jumping/dropping, the degree of rake provides a bit of extra stability without taking away from the agile nature of the bike. He also loves going to dirt jump and downhill parks. He's ridden in a few dirt jump parks and he's psyched on how it handles. I know it will be great on true downhill trails once some parks start to open up this summer. All in all, he couldn't be more stoked. It's a super sweet bike that has perfect balance for all the usual types of riding li'l rippers love.

    Prevelo is amazing

    When our youngest son started to get frustrated on his Specialized Hotrock 16 (because of the coaster break and the weight) I started doing research. We needed a bike that had hand breaks and was a reasonable weight for a 5 year old to handle on the trails. We decided to invest in the Prevelo Alpa Two and, man, was it worth it! It completely changed biking for our little guy. Suddenly he could keep up with the rest of the family on trails and his love of biking grew exponentially. When it came time to trade up to a 20” I did my research again and again came back to Prevelo. The customer service is unmatched! I called Prevelo with some questions about the Zulu Three and was blown away by the responsiveness and personalized service. We live in Maine and we got the bike in January (aka snow season) but he has already taken it out on a few rides because he just couldn’t wait to ride his new Zulu Three. The quality of the parts is superb and the bike is perfectly designed for a young rider. We are all thrilled.
