One of the most commonly asked questions about electric bikes is “how fast can I go?”
The legal power output for a road-going electric bike in New Zealand is 300 watts. A 300 watt electric bike will typically reach speeds of 32-35km/hour unassisted. Beyond that, it’s up to you and the power of your legs, or gaining extra momentum on a downhill stretch.
In Europe, the legal power output is 250 watts, which will assist an ebike to a maximum of 25km/hour. If you’re buying a European brand of ebike in NZ, it will most likely have a 250 watt motor and be limited to 25km/hour.
Can I change the factory speed settings?
On some makes and models such as these, the answer is “Yes.” And it is quite easy to do. Bear in mind however that a 300 watt motor is 0.4 horsepower, so even if you override the factory settings to say 40km/hour, a 300 watt motor is still going to max out its assistance at around 35km/hour.
