I build my own bikes and I definitely used to go faster on average when I had a more powerful motor and/or higher limits. I’ve done trips on the 1.5kW Tangent where I’ve averaged 45kph. These days I ride small 250W hubs, limited to 700W (overpowered) but with pedal assist that tops out at 2x human power. That way I can’t go much more than 400W continuous. At the same time I get high torque when starting from a stop. Which is more or less what factory ebikes with torque pedal assist do. I now average 25-28kph.
