FAQ

Chedech is a small-wheeled city folding bike. We usually call it folding bike or folding mini-velo. Chedech is a city bike, not a mountain bike. Several fatigue tests have been conducted, and we are confident that our bike frame is strong enough for the rigors of urban riding!

No! Chedech is not an experiment bike. Rather, it is a very practical bike. This is not much different from a standard, everyday high quality bike. However, this is the last bike that could have been possibly made of carbon, and we made it. In that way, it’s a huge advancement!

Chedech has a wheel size of 18 inches, which makes it interchangeable with other standard 18 inch wheels. Some bikes use odd sizes that are not standard, forcing the user to buy all replacement parts directly from that manufacturer at a higher cost. Again, we are using an android model for maximum compatibility. 16 inch is too small for the riding comfort level, and 20 inch would interfere with the folding mechanism. 18 inch is becoming more popular in this category of bicycle. Tannus currently makes an 18 inch puncture-free polymer tire that is perfectly suited for city bikes.

We have released Chedech with the very strongest carbon fiber available. It is light and durable! There’s always a bit of a trade-off. Many bike riders require a folding bike that is as light as possible, but rides smooth. Chedech appeal to riders who want a carbon fiber folding bike that includes some other exciting wish-list features. Having said that, there’s something to be said for good old British steel, and many bike riders would rather have a heavy bike that is nearly indestructible. Chedech will be durable, but it will not be a tank.

A carbon folding bike has not been easy for us to produce, and this may be why there aren’t many (if any) high quality, yet affordable models on the market.

This bike can surprisingly accommodate a wide range of riders. However, in order to maintain safety and a good ride, cyclists should be under 100kg.

Like all folding bicycles, Chedech features a one-sized frame. We designed it as a mini-velo, and therefore does not have the size flexibility of full-size  non-folding diamond “triangle” frames. We have designed it so that, the distance between the front wheel and the rear wheel is shorter than standard frames. The weight of the bike rider can be leaning backward when riding uphill and forward for riding downhill — our bike is light, so rider needs to be careful when traveling on steep inclines and declines.

Chedech is a mini-velo folding bike. It only has one size frame. However, we will prepare two different handle type to help accommodate different size riders.

We carefully considered whether or not to have rear suspension. It adds riding comfort, but also adds a little weight. Ultimately we felt that the suspension elastomer was an important component to deliver the ultra smooth ride you notice immediately.

Currently, the air pressure is 85psi.

chedech is 5 gears model.
Chainring teeth: 46T
Casette= Sturmey Archer SRF5(w) 5-speed internal hub
(Sprocket teeth= 13T).

Gear Ratio:
• Gear 1 – 62.5%
• Gear 2 – 75%
• Gear 3 – 100%
• Gear 4 – 133.3%
• Gear 5 – 160%

A few small parts may be susceptible to rusting. For an example, the tip of brake line is covered by iron, which can rust. The majority of parts on our bikes will not rust.  We recommend that after riding, the steel parts be cleaned and dried off with a towel or cloth.

Our frame is built in China, other parts are from Japan and China. Assembly and quality control is done in Korea.

Shipping time varies. It normally takes about a week to ship from Korea to USA.

We ship fully assembled. Note:  You may need to adjust brake lever angle and a few other things to accommodate your body size.

Safety test from Korea Certification inspection takes very strict and particular process, so people who had doubts about making a folding bike with carbon should now relieve.

KC (Korea Certification) Inspection process as follows:
1. Frame & Front Fork Assembly – Impact Test: A weight of 22.5kg is dropped onto the front axle of the upright frame-fork unit from a 180mm height.
2. Fatigue Test of Cycling Forces: Alternating push force on both side of pedal spindle for 100,000 cycles and having amplitude of 1000N.
3. Fatigue Test of Vertical Forces: Alternating push force on seat tube for 50,000 cycles and having amplitude of 1200N.

chedech perfectly passed all inspections points.

Bicycling involves risk of injury and damage. By choosing to ride a bicycle, you assume the all responsibility for that risk, so it is important to understand and practice the rules of safe riding and of proper use and maintenance of your bicycle.

We would like to announce the increase of chedech’s frame warranty to three years. Initially, we believed that one year was enough, but we concluded that three years demonstrates greater confidence in our bike and provides customers with extra protection and peace of mind. Please check below “Warranty” for detailed information.
