Chedech

Designed to be light, strong and give a superb riding experience, the Chedech from Korea is a cycling innovation that has to be ridden to be fully appreciated

Ride it. Love it. Chedech All-Carbon 

The New All-Carbon Chedech 18" folding bicycle is a ground breaking innovative bicycle with many features that result in a superior riding experience.

   

Strong and Durable. We completely understand where to use carbon and where to use metal. For the folding hinges, we used metal to keep it strong for folding movements. For the other frame parts we used carbon to keep the bike light and comfortable. In addition, we use a stronger carbon material for the parts connecting the metal hinge and carbon frames. This is done by adding extra chemicals, which make those linking parts stronger than the other carbon areas.

Flexibility. It’s commonly known that a carbon frame gives a much more comfortable riding experience, especially for long journeys. Many bike riders think that it’s natural for a mini-velo to shake and vibrate a lot because of the smaller wheels that rotate more cycles per distance as compared to standard size wheel sets, as well as shorter forks. We solved this shaking (or vibrating) problem by using a carbon material, because carbon absorbs impact and vibration. Chedech gives the rider a smooth carbon bike and flexible riding experience. You will feel and enjoy the carbon body in each pedal stroke. The bike will glide a long way even when you stop pedaling.

Great Looking Design! It was not easy creating a unique style for Chedech. It’s a fast riding carbon bike that is also comfortable. We could either show our bike as easy-riding with a more comfortable look, or we could show our bike as a fast riding carbon bike with a sharp shape. So, we were initially torn between the two design concepts, but finally we found a balance that we hope you like. Chedech looks comfy and fast.

 

Technical Features. This bike was designed with many technical improvement and new innovations.

 

Hexa Form Main Frame. The main frame has a hexa form, which makes the frame resist against twisting. In order to make it foldable into a compact, small size, we adopted a one line frame system, not a triangle system that often leads to an unstable riding condition due to the bike being affected by twisting between the handle and the saddle.

 

Chemically Reinforced Carbon Fiber. Our study group tested many different carbon fibers in order to diminish the twisting movement on the frame. We did everything possible to come up with a more stable frame, such as testing different fibers, adding extra chemicals, or adopting various ways of adding carbon sheet per each part. As a result, the final product has a much stronger frame than normally experienced in carbon frames.

Hidden Wall Inside the Frame. To reinforce and strengthen the frame to resist twisting and maximize stiffness, we came up with a new design concept. A wall is inserted into the frame that gives more support that resists against pulling in one direction. This added a little weight, but helped us complete a dream bike that features a one line carbon frame that does not shake while riding. This internal wall features in the main frame, handle post and seat post, the result being the Chedech is super stable, and immediately noticeable.

New Folding Mechanism. In order to make a more competitive folding bike, we paid careful attention to the folding mechanism. We studied the way other bikes folded and tried to make our own way to attain a more stable and faster movement while folding. The hinge between the main frame and rear frame is a new invention that allows speedy folding and unfolding. Special hinges were developed for this new quick release system.

Optimum geometry for a one size frame bike Most folding mini-velos are limited in frame size due to the folding mechanism, and they offer only one size, regardless of the bike-rider’s height. Nevertheless, it’s very important to design a one frame size bike that is capable of accommodating different sized cyclists. The Chedech is very stable for most bike-riders, regardless of uphill or downhill cycling. This well-balanced geometry allows a wider variety for the bike-rider and more stability.

Speed. The main concern for a bike is speed. But this factor is forgotten for many folding bikes. Most manufacturers ignore speed in order to make the bike foldable. Impact absorption is often sacrificed in favor of small wheels. So, this foldable mini-velo is not fast or does not allow fast riding with added vibration. But you don’t need to worry about losing speed with foldable mini-velo now. With Chedech’s anti-twist main frame design, you can run fast as much as you do with carbon road bike. Most testers started their review with one sentence, that they could feel the riding emotion when they usually have with a carbon road bike, and we think that is good explanation for the final Chedech. It gives fast and smooth riding condition.

Weight. All bike designers get stressed-out about weight, especially with folding bike designs. A lighter bike is often the reason someone buys. For a folding bike, weight is a topic of much discussion and research because most cyclists want to carry their bike inside public transportation, into buildings, and even store under their desks. A stable carbon folding bike could not be made for several decades, so the task has been impossible to solve until now. With Chedech, you can have the first hand-carryable, light, folding bike. Chedech-5 (five speed bike) is 9kg, and Chedech-1 is single speed bike, with weight of 8kg only.

Made in Korea with love and inspiration

Fast and easy to fold into a small, convenient, compact size. One of the main features of Chedech is its small-sized folding function, which is perfectly suited for commuting. And, when you arrive at work you don’t need to let your bike stand outside in all weather, unwatched. You can keep it under your desk and then quickly unfold it for the ride home.

Chedech’s folding mechanism was built with time management in mind. We invented a quick release system and even a new hinge system for the main folding part. When folded, Chedech is secure and easy to carry.

Lightweight.   Chedech uses a special carbon material throughout the frame (main and rear) and handles.All the major parts are made of carbon fiber, and that leads to a lightweight bike. Our five-speed model is only 9kg (without pedal) and the single speed model is a mere 8kg.This lightweight design helps you to ride faster, and you can also ride uphill more easily. Just like a good carbon road bike, it feels like someone is pushing you from behind per each
