Development of E-Bikes
Our Story
At IDbike, we believe cycling should be more than just a way to get from A to B, it should be an experience powered by precision and innovation. Since 1997, we have been at the forefront of e-bike technology, pioneering torque sensors, smart controllers, and complete drivetrain solutions that have shaped the way people ride.
IDbike, is dedicated to bring innovative technology to the bicycle industry. Initially, IDbike focused on development services for bicycle manufacturers, designing custom components such as an adjustable handlebar that allowed the rider to change postition while cycling. However, in 1998, IDbike conducted research to create the perfect electric bicycle. We realized soon enough that and electric bike should not only look like a regular bike but also has to feel like one. Based on these insights, IDbike began developing a new generation of electric bikes.
Development of the first E-Bike prototype:
A Vision for the future (1998-2001)
By 1999, IDbike developed its first full e-bike prototype: The Ebow, a project for Accel Group. The goal was to create an affordable (1000 guilder) e-bike that looked and felt like a traditional bicycle, instead of the bulky, outdated designs common at the time.
The Ebow Featured:
- A rear-wheel motor
- An integrated battery hidden in the frame
- A torque sensor in the rear axle for more design flexibility
One of the biggest breakthroughs was the development of the TMM1 sensor (Torque Measurement Method 1). Through extensive testing, we discovered that the rear axle was the most reliable place to measure torque, as it was free from external forces that could interfere with its accuracy.
This prototype caught the attention of Sparta, leading to the development of the Sparta ION, which debuted in 2001 at the IFMA Bicycle show in Cologne. This was a pivotal moment for IDbike, since our technology and extensive research was recognized.
At first, the Sparta ION was met with skepticism, as many still viewed e-bikes as mobility aids for older cyclist. But as time progressed, people discovered the joy of riding faster, further, and with less-effort, and the perception of e-bikes began to shift.
Revolutionizing E-Bike Technology:
The TMM Torque Sensors (1999-2009)
IDbike quickly became known for its torque sensor innovation, developing five patented Torque Measurement Methods (TMM) between 1999 and 2009.Each version improved upon the last, adressing several different needs:
- TMM1 (1999): Integrated into the rear axle, compact design and efficient power transfer
- TMM2 (Early 2000s): Designed for speed hub cones
- TMM3 (Mid-2000s): Applied in fitness and spinning equipment
- TMM4 (2006): Rear dropout torque sensor, known for its durability, precision, and affordability
- TMM5 (Late 2000s): Designed for chain ring integration, compatible with unmodified and mid-motor bicycles
While some sensors found niche applications, TMM4 became a market standard, used by leading brands such as Stromer, Klever, Opium, and Kettler.
Expanding Expertise:
From Sensors to Full E-Bike Systems (2005-2013)
In 2005, IDbike contributed prototype sensors to JD TranzX E-Drive Systems, further shaping our expertise in torque-based pedal assist. IDbike played another key role in the development of Gazelle’s Innergy e-bike (2006), which later won Bike of the Year in 2009.
2009 was a turning point for IDbike. That years we:
- Developed the Ultra Motor A2B Hybrid, our first project using in-house manufactured sensors
- Began manufacturing the TMM4 sensor in the Netherlands to ensure quality control and stability.
This shift in production was very important, as bike manufacturers had struggled to implement sensor technology correctly, leading to unreliable performance. Brining sensor production in-house allowed IDbike to refine the technology and ensure consistent quality.
Software and Future Innovations:
Perfecting the Ride Experience (2013 - Now)
As e-bikes became more complex and software-driven, IDbike realized that the true key to a natural riding experience was found in precisely tuned control algorithms. Without intelligent software, even the best sensors and motors could not deliver the cycling experience that riders expected.
Today, we dedicate ourselves to refining software, ensuring that every bike using IDbike technology provides a natural pedal response. Innovation never stops at IDbike. Over the recent years, we have developed a range of next-generation torque sensors. Which are smaller, more precise, and highly adaptable to different e-bikes. One of our most significant breakthroughs has been the Super Compact Sensor for through-axle bikes.
This sensor was developed to meet the growing demand for lightweight, high-performance e-bikes, ensuring precision torque measurement without adding bulk.
By continuously refining our sensor technology, we ensure that IDbike-equipped e-bikes provide a predictable, repeatable, and stable ride under all circumstances, regardless of:
- Weather conditions and temeprature changes
- Rider weight variations
- Road conditions and vibrations
- Ageing of the bike or drivetrain system
Today, IDbike works closely with OEM’s worldwide, providing custom torque sensors, intelligent motor controllers, and complete e-bike systems. Every product is designed, tested, and manufactured in-house to ensure the highest level of quality and performance.
IDbike is located in the south of the Netherlands, the heartland of the European E-bike (Pedelec), only 1,5 hours from Amsterdam Airport.
