E-bike central motor
In cooperation with its partners, Domel has developed one of the most powerful hybrid central drives for e-bikes. The 700W power can hold for 200 seconds. The electric drive provides additional assistance to the cyclist when needed. The central drive is used for the extraordinary requirements of mountain biking and where the energy efficiency and responsiveness of the whole set are important. The responsiveness of the engine depends on the intensity with which the user applies pressure on the pedals.
The drive is equipped with an innovative high-efficiency BLDC motor, with innovative construction and technology that enables a long life, quiet motor operation and high material efficiency of up to 87%. The motor is extremely energy efficient in terms of power.
To be used in various bikes
The drive unit is currently adapted for demanding mountain bikers who like to climb forest paths as fast as they descend. It helps the rider with 750W of power and up to 150 Nm of torque, which is as much torque as a small passenger car can achieve.
The drive is versatile, perfect for experienced mountain bikers and those who want to travel a longer distance in a faster time. Thanks to the excellent Domel motor, the drive at the lowest level of assistance is energy efficient, and thus enables users to cycle long distances.
Due to its high power, the drive is excellent for delivery or cargo bikes.
Precise sensors and software enable optimisation that is suitable for lower speeds and higher starting torque. Due to the weight of the bike, the cyclist on a delivery or cargo bike starts to turn the pedals slowly, where even at a very low cadence the motor provides a great deal of help. The motor can then hold a nominal power of 450W for a very long time, which is suitable for a powerful e-bike or delivery bike. Due to all these features, the drive is also suitable for tricycles or quadricycles.
The drive is also installed on "speed" bikes, which are currently becoming more popular. With the same power, it helps the cyclist reach a speed of up to 45 km/h.
Advantages:
- Technological solutions have placed the new drive at the very top of performance in the global market.
- It is classified in the highest quality class.
- The Domel drive has the highest torque on the e-bike market, and has the best weight / torque ratio in this respect.
- The drive software can be customised. It is made in such a way that the buyer or distributor of an e-bike can optimise it on their own, thus making it meet their own needs or desires with regard to the drive. The speed is adjustable according to customer requirements.
- This is the only product on the market where the motor helps at a very low cadence (and thus at low revs).
Development
The development of the e-bike drive was a big challenge for Domel, due to the complexity of the drive unit. The development team gradually upgraded and strengthened its knowledge during this process, and at the same time the drive became increasingly optimised.
As a result of this hard work we have won several awards for this hybrid central drive: a Gold Award for the company Domel, as well as Gold Awards at the regional and national levels for the best innovation from the Chamber of Commerce and Industry of Slovenia. (link to news)
Domel has a range of motors available, designed for a system voltage ranging from 12V to 48V, and with mechanical power output up to 1 kW. Specific design options can be developed in compliance with particular customer needs.
Early collaboration is critical to developing a feasible solution that meets your needs, optimises application performance and minimises risks in relation to product reliability, cost overruns and program schedule. We collaborate with you from the product design stage to commercialisation in order to achieve the overall objectives of the project.
With simulations, our own prototype construction facility and in-house test department, we can implement your initial product idea successfully and take it to series production in the shortest possible time.
More Domel insights:
Let’s take a closer look at why the e-bike is so amazing. It contributes to sustainable mobility and also helps improve the health of individuals and of society as a whole. The option of purchasing a Domel-driven e-bike bearing your company’s logo provides an additional incentive for increasing physical activity. Did you know that we offer personalised bikes? Riding an e-bike can help employees improve their physical fitness, reduce their stress levels and help them on their way towards a healthier lifestyle. They can now incorporate physical exercise into their daily routine, which eliminates the need to spend time at the gym. But that’s not all the e-bike has to offer. Adaptable mobility is another one of its many super powers, helping employees avoid traffic jams and providing them with a fast and efficient means of getting around. E-bikes are perfect for shorter or medium-length distances, and can be combined with public transport for the best results. And let’s not forget about how much money they can save on fuel and parking charges. E-bikes can open the door to mobility and independence for every employee, not all of whom will have a driving licence or a car. Let’s take a look at how e-bikes are saving the planet. Their CO2 emissions are low because they don’t produce direct exhaust gases or particles. This improves air quality. Domel encourages its employees to adopt a healthy and active lifestyle in their free time. It places great emphasis on recreation, to which it gives substantial financial support. We help finance recreational activities away from the workplace, including skiing, swimming and group recreation in sports halls. We also co-finance massages, visits to the sauna, and holiday accommodation by the sea and at spa resorts. We cover the registration fee in full for employees who wish to take part in running and cycling events, subsidise season tickets for the swimming pool, sauna and tennis facilities at Ratitovec institute, and provide vouchers for group exercise, fitness, massage and recreational swimming in Železniki, Škofja Loka and Kranj. During the summer months, we exercise and take part in various events at Selca sports park. Every year we organise an unforgettable employee picnic, which provides a perfect mix of entertainment and sport. In the autumn and winter we organise group recreation, where employees can play badminton, table tennis, five-a-side football, volleyball or basketball for free. There can be no excuse for not taking part in fitness or group activities on grounds of price, as we provide vouchers that keep costs to a minimum. And if you’re a skiing enthusiast, you’ve come to the right place, with low-price ski passes available for the Soriška Planina, Stari Vrh, and Cerkno ski resorts. Every day we make a wide range of apples available for our employees. We do all of this to promote sustainability and our employees’ health. E-bikes are proving to be a key factor in the development of a more sustainable future. Not only do they reduce CO2 emissions, but they also provide long-term benefits for individuals and the environment. The combination of fun, recreation and e-bikes gives our employees an unforgettable experience. We are building a more sustainable future – one that connects us and makes us healthier, happier and full of energy.
