Do you want a bike that can roll over any terrain - rocks, sand, snow - with ease? The BionX powered Surly Moonlander's fat tires and powerful motor will cruise you right over anything in your path. The Moonlander is what's called a fat bike, named after the 4.7 inch wide (really!) tires that allow it you to float like your riding on the moon!

Though the tires may look big and heavy remember they aren't solid, they're filled with air, and are actually very light weight. The whole bike only weighs about 45 lbs with the BionX motor kit added on. That's the same as most of our BionX conversions. With the motor boost of your very own Moonlander BionX bike you'll be able to climb hills and go distance with ease.

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!
