Questions & Answers

Design and configurations

Why have you chosen to fit Erik with mechanical brakes?

All else being equal, there is no inherent difference between the braking ability of a cable brake and a hydraulic brake. The hydraulic does however feel firmer because of the cables ability to cushion the load. 

It is a popular belief that hydraulic brakes provide better braking effect than mechanical, but it is really a reaction to the difference between single and double action that most people are comparing. Double action calipers are considerably more efficient because they are grabbing the disk evenly from both sides instead of deflecting the disk from the one side in towards the second brake pad. 

We have chosen double action cable because, despite being more expensive than the hydraulic options (yes more expensive), they are much easier to service and maintain and therefore better suited to everyday wear and tear in an urban environment where they need to perform day in and day out in all kinds of weather. They need to do so without you having to worry about bleeding them, temperature changes, or kinks in the tubing due to people having treated them roughly while parked on the street. Cable is just easier to service and maintain on the go and therefore we believe it is more appropriate for urban bicycles.

Why choose a belt drive instead of a chain?

All of our urban bicycles are kitted with internal gears and a Gates Carbon beltdrive for ease of maintenance and a smoother ride. Belt drives provide silent power transfer, last up to four times longer than a chain, can never rust or smear oil on your pant leg and so you are guaranteed years of low-maintenance riding in all conditions. Only maintenance needed is an occasional rinse with water and a soft brush. Simple as that. 

Why did you design the Erik for 650B wheels?

Despite the illusion, there is no reason that large wheels are any faster than smaller wheels. Actually it is easier to get smaller wheels up to speed and that means they accelerate faster. Maybe the best example of this is that the 200 meter flying start World Speed record is held by a bike with 17” wheels – and it has been so for the past 33 years. All else being equal, smaller wheels accelerate faster than bigger ones and that means they are much better suited for urban riding, where one often has to stop at lights and stop signs.

Another reason we designed with 650B’s is that the bike has a pretty sporty front end geometry and the 650B’s reduce the percentage of radial instance of toe overlap. This makes the bike a lot easier to handle without compromising the very sporty feel.

So, what are the disadvantages of smaller wheels? In extreme cases, smaller wheels give a harsher ride on rough terrain like cobble stones, but that is not an issue for a frame like the Erik, which has a natural ability to absorb road vibration.

Why have you chosen to fit mechanical gear shifters on your gravel and road bikes?

Coh&Co’s stock bikes are assembled with mechanical group sets because they are a solid, time proven and serviceable solution. Combine all of this with being cost effective and a tinge of traditionalism and it seems like the natural choice. Having said this, we do recognise that “times they are a changin'” and that electronic group sets perform great. So for those who just love gadgets, we can offer electronic shifter set upgrades for our carbon road racing frames. Our WOOCA and Erik frames just aren’t designed for them – as of yet.

Can I use tubeless tires for the Erik?

Our rims are tubeless ready meaning that with a conversion kit it is possible to change for tubeless.

Do you offer frame kits?

We offer our WOOCA bikes as frame kits. 

All of our other models are sold as fully assembled bikes.

Do you offer electrical bicycles?

Yes.

For our urban models we will soon be offering the Erik with a rear hub electric motor and battery in one. It is automatically recharged and has an impressive range of up to 50 kilometers at 250W. The Erik Electric is lightweight, simple in its design and easy to use. Watch out for it as we aim to launch it in the summer 2020.

Our VeloSled cargo bike is also offered with a high quality rear hub drive from German NeoDrive. Sign up for our newsletter for more information when we are ready for launch.

Cargobikes

Why have you chosen a rear hub drive for the electric version of the VeloSled?

Our rear hub driven, electric motor solution can be fitted to any sled, so that when the kids are old enough to ride by themselves, your sled can become yours again and be on stand by as the ”family wagon”. The VeloSled is designed to be modular so that the motor option can be swopped on or off throughout its life and the rack combination and accessories can be added or removed as needed.

What's the idea behind lefty steering?

Forks make plenty of sense when put on a traditional bicycle but as soon as we separate the front wheel steering axis from the handlebars and move the front wheel way out in front; then they make about as much sense as they do on an automobile. Some cars once had forks but they are neither necessary nor efficient. A lefty configuration allows us to make a stiffer composite frame assembly and reduce the height over the front wheel so that we can extend the bed without raising its center of gravity.

Why have you chosen to build a cargo bike in composite material?

Two wheeled cargo bikes are long and can carry a lot of weight. This means that they present unusual challenges when it comes to dealing with frame twist. We chose our own StoneWeave material technology (carbon and basalt) because it is several times stiffer than aluminium and much better at withstanding fatigue than most other materials.

Additionally StoneWeave does not corrode which makes it well suited for the task at hand and is phenomenally tough and quite repairable.

We have designed our laminate with maintainability and reparability in mind should it ever be damaged.

Do you offer an additional canopy to cover children completely from heavy rain?

Not as of yet but we will get there!

The Coh&Co philosophy

What does the 'Bicycles for life' philosophy stand for?

Coh&Co Copenhagen is a bicycle brand and manufacturer with the mission to bring new riding experiences, quality and a sustainable mindset to urban cycling.

All Coh&Co Copenhagen bikes come with a lifetime warranty and a buy back guarantee, as we take responsibility for recycling the frame or rekindling it for further use – we call it Bicycles For Life

What is StoneWeave material technology?

The name ’StoneWeave’ refers to Coh&Co Copenhagen’s new and radical frame building technology. Interweaving carbon and stone fibres, and fusing them in the world’s first recyclable high performance composite resin, opens new doors for sustainable composite technologies as such – and for the utilisation of composites for bike manufacturers in particular.

In addition to being the world’s first fully reclaimable composite bicycle, our StoneWeave technology lends itself to producing exceptionally tough frames at reasonable weights. Tough as can be and void of the corrosion issues so common to traditional urban frame technologies, StoneWeave frames are ideal for creating the low maintenance high power ride craved by urban bike commuters.

How is StoneWeave a sustainable material technology?

Coh&Co’s Stoneweave technology is unique and it is producing the worlds first recyclable composite bicycles. As many of you may be aware, carbon fiber composites have a very high CO2 foot print and we can’t hide this – on the other hand they have the potentiel for a very long lifespan and they open the door for some really unique design opportunities. No one can deny the fact that when measured by the kilo carbon fiber composites have a CO2 footprint many times that of a material like steel. Fortunately we don’t need a lot of it to make a great bike. What Stoneweave is opening the door for is reutilising these materials so that their material lifespan has a proportionally lower material lifecycle footprint. We believe that in recycling Stoneweave we can reduce the materials CO2 footprint so that it becomes comparable to and even better than some metals while still offering the fantastic design opportunities that composites so famous for.

How is this done?
In short, we can dissolve the resin system back out of the retired frame. This is done utilising a controlled low energy chemical process that relinquishes near virgin fiber and a series of resin substrates all of which can be utilised in other areas in industry.

What does "Lifetime warranty" mean?

When receiving your new Coh&Co bicycle all you have to do is opt in online and take good care of your bike. Each bike comes with a QR code  and a frame number (to be found inside the driveside chain stay) and these can be used to register an ownership profile that initiates the Bicycles for life warranty.

Once the warranty is initiated it will provide you with all maintenance manuals and guidance and keep a digital profile of your bike. Upgrades and maintenance notes are sent to this user account in much the same manner as we would normally receive a software update. This is your personal warranty and it is valid forever as long as you maintain an uninterrupted profile.

Coh&Co’s warranty is transferrable should you wish to pass on ownership of the bike, and as such acts as theft protection as well. Transfer of ownership takes a day or two and needs to be approved through Coh&Co in Copenhagen – this helps us to confirm that ownership is being transferred with your consent and not by a third party.

Buy back guarantee
After 10 years the warranty converts into a buy back guarantee in which Coh&Co Copenhagen buys back used bicycles. Whenever practical and possible possible we will always chose to refurbish a used bike for resale and get it back out on the streets. If not, we are dedicated to reclaiming the material, extending and its lifecycle beyond that of the bicycle frame alone.

When buying back the bicycle from you we assess the value of the bike on its service history and general appearance of the bike and then we will report back to you with a reclamation agreement that lets you know how much you can expect to be paid for the bicycle. Refurbished bikes will be up for grabs online or passed on to one of our resellers at a reduced price. Refurbished bicycles are sold on commission and you will receive the agreed upon amount when we have found the bicycle a new home.

Responsible disposal
Should the bike be damaged beyond the point where it makes sense to refurbish it we will buy back the bicycle at a minimum price and take responsibility for recycling the frame materials and components. Our unique material technology (StoneWeave) makes it possible for us to extract the fibres as well as the matrix in a condition where they can find a new life in other industrial products in the plastics industry.

Why make bikes out of wood, carbon and stone?

As designers and engineers we are fascinated by materials and our pallete of material tools here at Coh&Co Copenhagen is quite broad. We began as carbonfiber and composite specialists in the marine industry and have since gained considerable experience in the design and manufacturing of different products, utilising everything from aluminium to stone, now also including our own developed material technology StoneWeave.

Given this background it is therefore not surprising that we at Coh&Co often get asked why we have chosen wood for our WOOCA bikes when we are so clearly open to other materials. Many assume that it is for aesthetic reasons, and although we are flattered by the complement, we believe that the beauty here is far more than skin deep. The beauty is in the ride.

General use and maintenance

Where do I go to have my Coh&Co bike serviced?

For servicing, any good local mechanic would be able to take care of your Coh&Co bike. Our urban bikes are designed to be low maintenance with belt drive, internal gears and solid components, so if you take good care of it we believe you would have a solid ride for a good long while. 

If you live in an area with a Coh&Co ambassador shop nearby, we would always recommend you to have any service done with them. Check our list of stores here. We regularly update it when new shops being added.

Maintenance guides online
When you buy your bike, we will ask you to register online where you will then have access to all the bikes specifications, year build, links to service manuals and so on. The online registration is also what provides you with the Lifetime warranty for the bike. Any custom components like our metal dropouts are modular and should they be damaged or worn, we can send replacements for you or your local mechanic to replace them. 

Which kind of lock should i choose for my Coh&Co bicycle?

We are all afraid of loosing what we love. This also goes for our bicycles, especially ones that we have saved up for and invested ourselves in. Bicycles tend to live a tough life in the city and there is good reason to think about where and how you leave your bicycle. 

We always recommend that if you do have the option to take your bicycle inside with you. In case this is not possible or if you’re out for groceries, we suggest that you lock it to a lamppost, sign post, fence or whatever solid object is nearby using a “chain lock”. 

All of us here at Coh&Co have fallen in love with the textile based chain locks from TexLocks in Leipzig. They offer various lengths and all come with a soft, smooth surface feel leaving your bike unscratched. It even comes with a nice attachment to store the lock underneath the seat or you can wear it over your shoulder as the soft nature of the material makes it a comfortable way to ride.
