About this project

Kervelo Bike - Your ergonomic, chain-less, low maintenance bike

With our "upright" bicycles, we have enjoyed the maintenance, the greasy chains and the gear shifting confusion with 2 dérailleurs. For some of us, after the ride, we felt the shoulders tired or got a pain in the back.

Though the existing recumbent bicycles, are bringing improved ergonomic and could be efficient to ride, they don't provide good visibility in the urban traffic. Also riding with the feet above the seat seems not "natural" for many and still the long chain is a maintenance challenge.

As a passionate cyclist and a mechanical engineer, i spent long evenings thinking about how to overcome these challenges, reading articles and making digital 3D models of possible solutions. Finally after the success of my early physical prototypes, i decided to develop further the KERVELO bike and trike to the market, that pionneer bikers would certainly love.

Kervelo brings new innovative solutions

The Kervelo bike has in the front wheel a gearing system with the crank shaft in its center. 

The chain and dérailleurs are removed which means less weight, no need to guess which gear you are using, and hence no endless adjustments of plus and minus screws.

So less weight, no more greasy pants, and easy maintenance.  

No more skipping, jumping, grinding and dislocating chains upon hitting potholes.

The Kervelo bike is a direct front wheel drive bicycle in a semi recumbent position which radically changes the riding style and improves the riding efficiency. With this comfortable position, the arms are relaxed and you can see straight ahead without bending your neck. 

Don't hesitate between the bicycle and the trike : take both !

Initially, the Kervelo frame will offer the possibility of 2 frame configurations : bicycle and tilting trike, using the same interface.

Bicycle reinvented and new opportunities

At the current stage, the latest prototype is very convincing in ease of steering, stability at high speed and smooth handling at low speed.

With our expertise in the front wheel direct drive bicycle, we have reinvented the bicycle and the trike to cover a wider range of use and variants with dedicated bag, pannier, seat or cases.

So what becomes easier and better now:

  • Commuting with the bike with small bag
  • Shopping, carrying goods with large bag
  • Travelling with luggages well packed
  • Commuting with a child on his/her seat 
  • Commuting with a pet in a cage 
  • Riding a rickshaw
  • Riding a tandem 
  • Riding a short wheel foldable bicycle 
  • and...many more! What have you been thinking?

If you are an active traveller and love to take the bike with you to your holiday location, the frame size and the wheel dimensions are designed to fit in a checked in baggage of maximum size and weight (L+W+H =158cm ). You will only pay a normal fee to the airline carrier for this extra suitcase, and the bike seat could well be in your 2nd checked in baggage :-)

  • Gearhub : up to 18 gears ( other variant : 9 or 12 gears )
  • Trike tilting up to 30deg 
  • Cable disc brake front and rear
  • Trike Tilting lockable when standing still
  • Seat adjustable in position and back rest in orientation
  • Bike frame and wheels designed for airlines checked in baggage
  • Bike electrical assistance ( 250W ) with battery on the carrier
  • Bike carrier for bag or pannier 
  • Trike platform for bag, pannier or specific cases

Additional specifications

The geometry of the front assembly has been tuned to minimize the torque at the handle bar due to pedalling. The Kervelo Bike design set up allows you to steer easily, from low to high speed.

When climbing on a steep road, the strong back rest will support the effort reaction due to pedalling. Pushing and pulling on the opposite pedals simultaneously will further ease the steering. 

At "walking" speed, your riding is relaxed and smooth. You can turn tight keeping legs away from the front wheel. The handling is still easy and comfortable with your legs also relaxed. 

At higher speed, as the turning radius is big, you don't need to rotate much the handle bar and the wheel won't touch your leg. The clearance is safe.

Health and safety benefits of riding The Kervelo: 

On the Kervelo bike  or trike, the riding position is comfortable and it solves many challenges from riding an upright bicycle :

  • Neck doesn't  bend
  • Vision straight and full ( Watch the scenery rather the front tyre ! )
  • No more backpain, 
  • Open-wide lungs to breath
  • Arms relaxed
  • Car like seating with ergonomic handlebar
  • Less fatigue
  • Feet in fore front ( Better in frontal incident )
  • Access to get on/off easier than upright bicycle
  • Feet easily on the ground ( Thanks to pedals and seat height )

As covered on .... 

 

 "....Design offers a seating position that combines the comfort of a fully-recumbent bike with the visibility of an upright:"

 

" The Kervelo Project is my attempt to simplify the transmission issue and improve the ergonomics in one solution - in-wheel transmission. "

Time line :

Prototype 4 - Production version  

We have already started the design of the Kervelo prototype 4 which is being developed for production to make the frame stiffer, to reduce the fabrication time and optimise the overall cost.

Below are the realistic renderings of the upcoming production version showing improved geometry and details from previous experience.

Riding test and production start 

This prototype 4 before the production phase, will be tested by different people in various conditions. This will be done to ensure that the performance, the ease of steering and the robustness are well in the genes of the bike.

Manufacturing plan 

Our focus has been and will remain the product development with external expertise adding rapidly value to the team in a tight schedule. For manufacturing, we have teamed up with an experienced and well reputed quality bike producer. It has all the required know-how of precision welding, painting and assembly. With this team, we will manufacture the right quality of the bicycles ( some pro cyclists can confirm : we are with the right people at the right place ! )

To produce the frame and its components with the best quality and in a cost effective manner, specific production tools are required to do the welding and the machining

Funding campaign

The funding campaign with your support will enable the manufacturing of a limited volume of ( 22 ) bicycle / trike for launching the commercial operations :

The budget will include the following activities : 

  • Design engineering bike and trike ( 3D model and 2D Drawing )
  • Manufacturing engineering ( Tooling design for bike frame and parts )
  • Tooling fabrication ( specific welding jig )
  • Production prototype manufacturing and test ( bike and trike )
  • 1st batch production : qty 4 off : July 2016 
  • 2nd batch production : qty 6 off : October 2016
  • 3rd batch production : qty 6 off : November 2016
  • 4th batch production : qty 6 off : December 2016

After the KICKSTARTER campaign:

As described above, the funding campaign will support the final design stage and the production of the first batches ( 22 off ).

The final distribution cost ( custom + shipping ) will be adjusted once the backer delivery location is known.

Depending on the backers wishes, we may have different situation : 

  • Backers with no bike / trike purchases :  production batches go to bike shops for test in Europe, USA  and other location if interest.
  • Backers with all bikes / trikes sold : production batches go to customers. A new production batch will be launched with distribution to bike shops and new customers.

The customers will have a personalized follow up and technical assistance where defect parts will be replaced immediately from our stock and covered by our guarantee.  A detail description of the incident should help the implementation of corrective action.

 The quantity per batch is the current capacity of the manufacturing facility. Our ambition is increase the manufacturing capacity, adjusted with the volume to produce. 

With the respect of our engagement for your delivery, we do prefer to commit to a realistic target rather than missing an unrealistic plan.

Kervelo network and team

After the Kickstarter campaign, we will continue developing the range of Kervelo bike and trike possibilities in order to offer the most enjoyable riding experience.

To help this purpose, we aim to establish an initial retailer network in Europe and USA/Canada where the bikes could be shipped for testing and sales. These will be the places where we will meet you. 

Further marketing initiatives and attendance at bike shows will also develop the Kervelo network with the support of local representatives.

Based on the support from the KICKSTARTER campaign and the enthusiastic feedback already received on our innovative bike solutions, we are strengthening and structuring our team:  : 

  • Manufacturing capabilities to respond to a growing future demand, 
  • Design office to multiply and offer innovations and new smart solutions, 
  • Sales and marketing force to communicate with the customers, listen and understand them.

Risks and challenges

All of our first 3 prototypes have proven the feasibility of the concept.
The last production prototype will conclude the development by optimising the design for the best fit, weight, quality and cost.

A challenge that we have to address is the adaptation of our production capacity to the demand if it grows rapidly and above expectations. 

To mitigate this risk, we have a flexible production facility and has the capacity to build and assemble more bicycles.
New manufacturing resources will be explored to sustain the Kervelo development.

Kervelo brings disruptive innovation and we have an agile team capable of developing and offering product variants for a dedicated bike and trike purpose.

Following the KickStarter campaign and for sustainable growth, we aim to strengthen our innovation and development process through close interactions with our backers and customers.
