Shimano motors are often regarded as the most natural-feeling systems because the assistance is very smooth and bike-like. Riders coming from traditional cycling backgrounds tend to love Shimano STEPS systems.

Not all e-Bike motors feel the same. Some are smooth and natural, others feel like a small motorbike hiding inside your frame, and a few can practically drag you up a mountain while you question your fitness choices.

Choosing an e-Bike with understanding what motor it has is like buying a sports car purely on the paint color. What a lot of e-Bike riders don’t know is just how much they differ and what they can do to the riding experience like a car's engine.
The truth is, modern electric bike motors and batteries are incredible, and they keep getting better each year. Most well-known companies do make great motors, but many people don't realize there are huge differences between them.
