As an expert sommelier and brewer, my expertise lies in the realm of wine and beer rather than electric bikes. However, I can certainly provide you with some information on the speed capabilities of the 72v Sur Ron e-bike.
The stock Sur Ron electric bike is known for its impressive speed and performance. With its 72v battery, the bike can reach speeds of up to 45-50 mph (72-80 km/h). This is already quite impressive for an electric bike and is more than sufficient for most riders' needs.
However, if you're looking for an even faster experience, there are modifications available that can push the Sur Ron's speed to new heights. One popular modification is the installation of a custom-built battery with a higher power output.
With an upgraded battery, the Sur Ron can achieve speeds of up to 75 mph (120 km/h). This is an incredibly fast speed for an electric bike and is sure to provide an exhilarating experience for riders seeking a thrill.
It's important to note that such modifications should only be attempted by experienced individuals who have a thorough understanding of electric bike mechanics. Additionally, it's crucial to ensure that any modifications are legal and comply with local regulations regarding e-bike speed limits.
To fully harness the power of the custom-built battery and achieve the desired speed, it's recommended to pair it with a high-performance controller. The stock controller of the Sur Ron may not be able to handle the intense power output of the upgraded battery, so a Nucular controller is often used to bring out the bike's best performance.
The stock 72v Sur Ron electric bike can reach speeds of up to 45-50 mph, which is already quite impressive. However, with the right modifications, such as a custom-built battery and a Nucular controller, speeds of up to 75 mph can be achieved. Remember to approach any modifications with caution and ensure they comply with local regulations.
