If you want an electric bike that can tackle any terrain, the Surly Moonlander electric bike with custom BionX motor is for you. With its fat, 4.7"-wide tires and powerful motor, this burly bike can roll over rocks, sand or snow with no problems. NYCeWheels stocks this awesome bike at a great price.

Though this bike looks beefy, it only weighs 45 pounds, including the BionX motor kit, a top-quality motor made in Canada that comes with a two-year warranty. The frame is built of tough, light Surly 4130 CroMoly steel. This bike's light weight and powerful motor combine to rocket you up steep hills with ease.

As its name implies, the Moonlander has been designed to take you to the final frontier, where no man or woman has gone on an electric bike before - beyond roads and trails and even through snowdrifts. If you're looking for the ultimate off-road electric bike that will also handle well on the road, take a look at the Moonlander.

Features of the Moonlander with BionX:

  • Moonlander frame is made of Surly 4130 CroMoly steel
  • Powerful BionX motor to heighten the joy of riding a bike
  • BionX is top quality, made in Canada
  • BionX offers 2 year warranty on everything
  • Ever ridden through a snow drift? Now you can!

Electric Surly Moonlander The Moonlander BionX, like its name implies, is meant to go beyond where normal bikes, even normal fat bikes, can go. It is designed from the ground up to ride where there are no roads, no trails, no people. Of course it's great on roads too and with a BionX kit on your Moonlander you'll be flying no matter where you ride!
