Motores ligeros para bicicletas


Oferta Tecnológica
Una joven empresa alemana ofrece un motor excepcionalmente ligero para bicicletas clásicas que solo pesa 500 gramos. La bicicleta es más ligera que una bicicleta eléctrica tradicional y se transporta fácilmente. El motor se basa en un nuevo diseño patentado, siendo sus requisitos de mantenimiento muy bajos, y crea las fuerzas de conducción necesarias por él mismo, siguiendo el principio de "tanto como sea necesario y tan poco como sea posible". La empresa busca socios en Europa con el fin de establecer acuerdos comerciales con asistencia técnica, así como socios fuera de Europa para establecer acuerdos de licencia.


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.
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.

Partner sought

Type and Role of 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.
