The SHIMANO STEPS e-bike system is designed for optimal function, with each component working together to deliver the ultimate riding experience. Even so, we know that there is a strong temptation for some to “tweak” their ride to get that extra perceived performance. These types of system modifications, though, result in the bike no longer meeting legal regulations for its intended use, which voids its warranty. Luckily, there are ways to effectively increase your bike’s performance while keeping its reliability, longevity and safety intact – as well as its warranty in case something goes wrong.
