No riding with 2 wheel power in your post on Mar 2nd?
What you need is anti spin/slip control. You should get with MWKeefer who got his working well enough for riding on ice and snow.

Hi
Until we go with 1 motor because the front one was not ready
Last week we mount it.
If you have some fw for Arduino for 2wd (I remember I read your post about it) please let me know how we can manage for it, I'm curious to test it
Thanks

Wow this is an increadble build my friend! I have never seen anything like this before. I understand that this is a prototype but the austhetics of the batteries is a little crazy maybe you could find a way to incorporate that more as an integral part of the frame.
What iam saying is to make the bike look better you need to incorporate the batteries more into the frame, so that there mass is lower and ceterlized for handling and visual appeal.xranalli said:
Also consider sculpting a fairings to add to protection and aerodynamics.
I am excited to see thus build progress.
Cheers

Nice bike, totally different concept. Is the front and rear disk brake located before reduction gear? What is the gear reduction rate?

Hi
prototype is not finished yet, and it is not the ultimate version
in fact on this prototype we are doing experiments on 2wd, the new one will have better layout to go
outroad.
If you want to test it when will be finish you will be welcome on Italy
or we can send to you a sample...we can discuss about this.

While I love the concept of 2WD bikes / motorcycles (I built one of the first 2WD ebikes about 8 years ago) and own/ride a Rokon 2WD gas motorcycle now, the reality of them has not quite equaled what my imagination imagined.
And yeah, I'd love to have a Cristini, if someone else would write the check.
I wish you good luck with your project.

Hi folks
Hereafter pictures of new front suspension, that in my mind should be more robust and reliable

Nice!xranalli said:
How does the fork geometry and wheel base length feels?

The front is really cool and precise 
. The rear mono needs further improvements. Short wheel base length makes it nicely reactive and easy to change direction. My dogs love it (I cannot say the same concerning their relationship with my 749..)!!

Set up a dirt course on the area in your video. Then after some practice, give it your best and time a few laps with 2wd, and the same with rear drive only. Be sure to break those wheels loose on turns. Let us know which is faster, along with your impressions. ie Is 2wd better, especially once the wheels break loose in poor traction conditions? Is there anything in terms of handling or stability for which 2wd seems to be a detriment?
Personally, I'm sold on 2wd despite not having tried it yet, but the majority seem to think it is some kind of detriment other than the additional unsprung weight in front.

I still have concerns on geometry. What does it make if you let hands off the steer on low/high speeds? Be careful with this tests. :lol:

it looks like it wants to turn left by itself

There is bigger problem actually.John Bozi said:
This is why I can go only about 50kmh on my BMX, up to 70 kmh on my MTB and any speed (tested up to 150kmh) on my moped. All about steering angle.

My MTB already had steep fork (so 70km OK), but with 20" rear bicycle tyre, dropping the back 3" lower, it CAN go much faster. My ass slides off the seat
PS Over 60kmh is ridiculous on any bicycle, so I have CAV3 stop me happy throttle wrist.

Hi folk
We did evolution, following pictures show new part for new prototype
