Sur Ron X Bike Review
It is quite heavy for an electric bike but fairly light for a dirt bike.
Sur ron x bike review. They didn t use any. Also known as the firefly or just sur ron. We review the new sur ron bee lightweight electric motorcycle. The breakdown to me the sur ron is as close to the perfect motorized two wheeler that fits right between a full suspension mountain bike and a small displacement ice internal combustion engine bike.
The most significant upgrade is its state of the art sine wave controller which makes it quieter and more powerful with much smoother throttle response. Other than the above items the x bike is the same as the standard sur ron with the added above features. The sur ron is built on a custom aluminum dirt bike frame that weighs in at about 110 lbs 50 kg. With a 6 kw 8 hp mid drive motor using a two stage reduction for higher.
