About Zulu Two Heir Lub Tsheb Kauj Vab Toj Roob Rau Menyuam Yaus

Zulu Two Heir yog lub tsheb kauj vab toj roob hardtail 16-nti uas tsim los rau cov menyuam yaus caij hauv tej kev toj roob. Qhov ntev ntawm ob lub log thiab qhov qauv tsim ntxeem me pab zam txim rau cov menyuam uas tseem tab tom kawm caij hauv tej kev toj roob. Lub bottom bracket qis thiab tus crank luv luv ua rau tus neeg caij nyob ze rau hauv av thiab tseem txhawb kev tsuj pedal kom zoo raws li lub cev. Lub frame yog ua los ntawm 6061 aluminum alloy, thiab cov brakes disc hydraulic pab kom nres tau yooj yim thiab muaj zog. Lub air fork tsim los rau cov log 16-nti, siv carbon fiber thiab aluminum kom txo qhov hnyav, thiab hloov kho tau rau cov neeg caij uas sib.

Unique Properties: The Prevelo Zulu Two Heir is the first 16-inch hardtail mountain bike. It is a trail-capable bike for very young riders. The long wheelbase and slack geometry are forgiving to young riders who are still learning how to ride on trails. Making this bike required a new airfork designed to fit small wheels and capable of working with lightweight riders. The Heir 16 fork is the first airfork designed for 16-inch bicycles and features carbon fiber and aluminum construction.
Dimensions & Packaging: Wheel Size: 16" inches
Fork: 60mm travel airfork with HM Carbon Fiber and AL6061 lowers and AL7050 hard anodized 30mm diameter stanchions and adjustable rebound, lockout and compression
Brakes: Hydraulic disc
Frame Material: 6061 aluminum alloy
Wheel base: 790mm
Tags: bicycle, bikes, childrens bike, kids bike, mountain bike, kids mountain bike, 16-inch bike
Production Technology: The frame is made of 6061 alloy and incorporates a special low bottom bracket design and short crank lengths to create a bike that keeps the rider low to the ground while maintaining good pedaling ergonomics. The cranks are cold forged aluminum and custom made to our specification for length. The Heir 16 fork on the Zulu Two Heir uses aluminum alloy and carbon fiber construction to minimize weight. The fork utilizes an air spring that can be adjusted to accommodate lightweight riders and adjustable rebound dampening.
Design Challenge: Prior to the development of the Zulu Two Heir, there was no air fork available for this size wheel. We needed to develop a fork that would work with a 16-inch wheel. We also spent time researching how children ride on trails. There was little understanding of optimum geometry for bicycles for very young children on trails. We needed to research and observe children riding to understand the best geometry.
Research: Our objective was to create a bicycle that would make children most confident riding a bicycle on trails. Our primary form of research was watching children ride on trails, and soliciting input from parents that frequently rode trails with their children. In particular watching children ride trails, and experimenting with different geometries and components. We found that children rode more confidently with bikes that were lower, had strong easy to user brakes, and had forgiven geometry and suspension that helped correct for learning mistakes over technical terrain.
Inspiration: The design was inspired by watching children learning to ride on trails. We wanted to design a bike that would make children more confident riding on trails. In order to be confident on trails, children need a bike that is forgiving and stable, and has easy to use brakes, and a low center of gravity.
Project Duration: The project started in 2017 in California. Prototyping completed April 2018. First production bikes available to ship to kids in the United States in November 2018. Continued refinement through December 2021.
Operation Flow: This design makes it easier for children to ride on trails.
