Don't need it:ride: 

Then why does the yamaha trials ebike have one? A hydraulic one at that which I find hilarious as they outright refuse to put one on any of their gas bikes.

A clutch is used for a lot more than changing gears.

It could have one but it does not need it. Some implementations use a "clutch" to save battery drain I think and maybe for other reasons. I am pretty sure the Alta Redshift didn't have a clutch.

Holy crap, look at the size of that rear sprocket!!!

The front sprocket looks really small too, like an 11 tooth.

Ya. The gearing needs fixed off drive motor. Lotta guys do a secondary drive sprocket on E motor setups to off set this.

Do you know if the Alta motor had internal gear reduction?

Edit:  Nevermind, it did.

The Redshift's motor weighs 15lbs and pushes power through a 3.5:1 gear reduction.

Shut it.  You don't decide who needs a clutch and who doesn't!

Looks svelte!!!

Looks like junk, same as the current one! An electric with radiators the size of a 450 ICE engine? This thread is dead....

It's just someone Macgivering something together.  Are they supposed to build a motorcycle from scratch just to test an electric motor?

It has reverse!

"SSE Sires Systems Engineering...October 12  · 

Quick status update, it runs and rides! Working through the Sevcon programming has been the biggest challenge so far, and I feel there is still a lot of room for improvement. Having reverse on a motocross bike is also pretty wild! More pics, video, and details coming soon."
