6kg for an ebike frame is not lightweight at all. Downhill mountain bike frame with traditional aluminium tubing weigh less and have to handle much greater forces.

This is not an ebike, it is an electric motorcycle. They are similar, but definitely separate classes. 13 lbs is crazy light for a motorcycle frame.

The thing is this really isn't a motorcycle at all.

The tires are Bicycle tires (cruiser tires for one) not rated at all for the kinds of speeds they are advertising.

The front suspension while rated for MTB downhill use (which puts up with some heavy stress loads) would need to be tested for those speeds as well.

The fact that they are taking speculative pre-orders for a $56,000 product and don't even give out a parts spec on their website is very fishy.

Even though it is constructed from bicycle parts, this would be considered a motorcycle by legal standards in the US. Ebikes in the US generally are not allowed to exceed 20mph, but the motor in this can go well above that limit. I believe the limit is actually lower in the EU[1]. They may have to market this as a motorcycle on this fact alone.

Without DOT approved tires, it's legal status is off-road vehicle.

Hopefully that picture was an early prototype. I can't imagine bicycle-grade parts passing any kind of safety inspection for a vehicle that's supposed travel at traffic speed.

From the photos in the article it appears to be a mountain bike with a electric motor - look at the front fork, the tiny MTB disc brakes, etc.

It is electric moped: https://en.wikipedia.org/wiki/Moped

> Strictly speaking, mopeds are driven by both an engine and by bicycle pedals

More of a scooter than a moped
