Partnering opportunity

Lightweight motor for bicycles


A young German company offers an exceptionally lightweight motor that can be mounted on classical bikes. The bike remains lighter than regular e-bikes and can easily be carried. The motor is based on a new patented design. Maintenance requirement is low. Partners are sought for commercial agreements with technical assistance in Europe and for license agreements outside of Europe.

Partner sought

In Europe partners are sought for commercial agreements with technical assistance: Potential partners are engineering companies with market access to the target group in their respective countries and regions. Partners could also be special interest bike shops, who offer retrofitting and tuning services and products. A further possibility would be a cooperation with a company interested in starting a new business area with electro-mobility. The companies should be ready to work with a young company and start on a smaller scale. The partner should intergrate the motor in their portfolio. The German company is ready to share experience, transfer the relevant know-how and assist with first installations. Outside of Europe: Licensees are sought who will organise and manage production and distribution in their respective country.


Cyclists are often undecided whether they should stick to their classic lightweight bicycle or switch to a heavy e-bike. A German company offers a new solution that facilitates this decision-making. They developed the world‘s lightest motor for bicycles. This motor is retrofittable and can be added to almost any type of classical bicycle. The motor weighs only 500 grams. Thus the bike remains a lightweight means of transport even with the electric motor as it weighs only 1/5 of a normal pedelec drive. The motor is designed for continuous operation and optional use. The motor is the only friction drive for bicycles with dynamic self-regulation of the contact pressure. It is not a further-development of the conventional static friction wheel drive but has a fundamentally different design. Its potential for a "standard motor" distinguishes this approach from all current concepts on the market. Two small electric motors are arranged on the left and right side of the rear wheel. The motors wedge at the rim flanks when the motors get started and drive the wheel forward. The motor creates its necessary driving forces largely by itself and follows the guiding principle of: "as much as necessary, as little as possible". At any speed, the motor finds the optimum contact pressure by itself and it does not slip in the wet. When not in use the motor can be folded away completely. Only little maintenance is required. A replacement of the friction ring will be required only after 7.000-10.000 km. This patented invention is different from all other friction wheel drives in the history of the bicycle due to the geometric arrangement of the swing axle with the engine mount and the solution for the power transmission at the friction wheel. Further characteristics that enable the small size of the engine are the wheel circumference, rotation speed and ventilation. The company is presently selling the motor in Germany in small series. In Europe partners, such as engineering companies, special bike shops or similar are sought to integrate the product in their portfolio within commercial agreements with technical assistance, where the German company will assist with know-how and first installations. Outside of Europe licensees are sought who would manufacture and market the product.

Advantages and innovations

The innovation lies in the completely new design. This design enables a small lightweight and cost-efficient motor that has a performance comparable to the engine power of established e-bike drives. The world’s lightest motor brings many advantages: • Easily portable across stairs • Almost maintenance-free • Durable performance • Three motor variations with a universally combinable modular system of brackets.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
