ZecOO Electric Motorcycle – Images + Specs + Video




Continuing our line of thought about Zero drivetrains being used in custom bikes, here’s the ZecOO, a Japanese-built essentially custom motorcycle built around the Zero drivetrain, designed by Koza Netu.  With hub-center steering, it’s certainly a design dream, maybe an engineering nightmare…  at the very least, a solution for a problem that doesn’t really exist, perhaps.

This is a story that’s a couple years old, though, but the dream still appears to be alive via Cycle World.  Mabye this is just breaking over in ICE bike land.

We searched around for clips of this thing actually under power, and found this.  Somehow, a couple of things come to mind.  The first, is an almost indescribable feeling of watching sort of a guy on a lawnmower pushing a shopping cart.  Second, a review we read back, oh maybe 20 years ago comparing several large touring bikes, and describing riding a Harley FLCH in the “twisties” segment of the review.  “The only thing scarier…” started the reviewer, “…than riding the Harley through the curves, was seeing another one coming at you from the other direction while doing so.”

As they’re advertising 50 kW, they’re likely using the SR powertrain (debuted in 2014). It may be somewhat newer than a couple of years.


I like the side profile, just awesome the way you can just sit up a bit more, more like a moped.

Remove the fairing, add a tray and there you have a freight bike!


Thanks for sharing Ted. Always enjoy the two wheeler articles.

I’m impressed. Really nice engineering and fabrication. Looks good too! Much better than a certain “Tesla” design that has popped up on the internet recently.


I’m a bit concerned that lower front suspension arm is going to touch-down in deep left hand turns.


Being a Harley rider myself, I can only half agree with the above statement. What scares me, is seeing anyone riding in the twisties coming at me who can barely ride in the straight-aways.

As to this design, single-sided-hub-center steering has been something of a unicorn. It’s hard to get all the parts right. It’s not as simple as putting the steering knuckle from a car into a bike, the steering geometry would be completely off. But it looks like they are using an asymmetrical wheel to compensate.

What the heck is with that rear sprocket? That thing is ridiculous.
