About us

We are PearControl s.r.o., a Czech technology company based in Pelhřimov. Since 2015, we have been developing and manufacturing tuning chips for e-bikes. Our goal is to push the limits of performance and the riding experience – which is why our products enable speed-limit removal and allow you to use the full potential of your e-bike.

From the very beginning, we have relied on in-house development, high-quality Czech production, and precise testing of every product. Thanks to this, we are now among the largest manufacturers of e-bike chips in the Czech Republic, with customers using our products all over the world.

Our chips are compatible with a wide range of drive systems – Bosch, Shimano, Yamaha, Brose, Panasonic, and Bafang. Each model is developed with an emphasis on reliability, easy installation, and maximum riding comfort.

We pride ourselves on an individual approach to customers, fast technical support, and continuous innovation. In addition to chip manufacturing, we also focus on developing software and accessories for e-bikes to offer cyclists a comprehensive solution for their needs.

Our vision is to be a long-term and reliable partner for e-bike owners around the world.
