This Electric Dirt bike is made flawlessly. The quality is awesome, the parts used are high quality and the company behind it is very serious China Design and Engineering company.

Their first concept drawing is not far away from production model

So how exactly can they sell it for 2000 + USD and remain profitable?

Because of Aluminium forging (Forging is a manufacturing process where metal is pressed, pounded or squeezed under great pressure to produce high-strength parts. Forged aluminum is ideal for applications where performance and safety are critical but a lighter-weight metal is needed for speed or energy efficiency.).

The Frame – weight: 7,8 kg


For Aluminium forged parts you need to invest more money at the beginning, but afterward, parts are inexpensive and still super smooth looking.

As you will see later on; the chosen components of the bike are HIGH END, but not the latest tech (thats also keeping the price low). The whole concept is made so most of us can afford it, and still, the speed and power is not jeopardized. Thats why Sur-Ron will be the talk of the 2018. We are pretty sure that they are going to crush the Electric Dirtbike market.
