I’ve just seen another kickstarter electric skateboard project called Kickr (17 days left if you’re interested in backing them)

I have to say I haven’t see anyone take  this approach which is refreshing. They’re making systems which can be easily attached to any longboard and mount off the end of axel (removing one of the nuts). Basically they’ve got some sandpaper stuck on the outside of a brushless motor that makes direct contact with the wheel.


Another point of interest is the throttle in the strap that holds the batteries to the board. I have no idea how that works but it sure does look interesting.




Stated specifications:

  • Quick install and removal
  • 20 miles per hour
  • 1100 Watts
  • 6 mile range between charges
  • 2 hour charge time
  • < 5 lbs. Weight
  • Lithium-ion battery pack
  • CNCed from stainless steel and aircraft-grade aluminum

We are confident we can assemble 100 units per month beginning in April.


  • The unique design
  • The price: At $399 plus postage its not a bad price at all. But as with all kickstarter projects your backing development not a finished product.
  • The interesting throttle control
  • The easy on easy off idea

Some points to think about:

  • The way the motor is mounted it looks like it has limited contact with the wheel. The motor isn’t completely cylindrical. Is it going to have the pulling power to get you up an incline or will it just stop and burn a hole in your wheel.
  • As the motor is screwed onto the end of the axel. I would think this could present some problems with stressingthe metal and it would be interesting to see how the design holds up over time.


Check it out and let me know what you think:

      • The friction contact is the real problem! I was using a hard skateboard wheel for contact and my longboard wheel is a normal soft one! U will got to have too much tight contact in order to deliver power however I didn’t even try to go up hill or even do a motor start without pushing first ! Cuz if u do something like that u will definitely start to ruin your contact friction and I’m sure this will also happen with the project there the grip tape will grind doing those situations and end up loosing contact!
