Hm a DIY open source Alta, where the community pulls together. I like that. I wish you the best and hope you can gather enough brain power and dedication to hit a home run. It is really too sad if BPR just will sit on the inventory and patents the picked up from the Alta closing. I applaud the initi...

Didn't take the time to watch that video, but iirc the company behind that tilting front end was also selling a DIY kit of those. So you could refit it to your own motorcycle.If they are still doing that you could have yourself a 3 wheeling Zero any day you like.

Unfortunately with more than three wheels in contact with the ground (or more than three wheels at all, in some places) by legal definitions in many places in the USA, it doesn't fit any of the motorcycle or scooter classes, leaving only the automotive classes (which it probalby doesn't qualify for...

Your dedication to this build never stops to amaze me. Such great work with the swing arm. Water cooled batteries. Man you are going all in on this build. I really look forward to the see videos from the the drag strip.

Electric three wheelers and 4 wheelers maybe? Electric can am side by side?
Really to bad that Alta motor went belly up, let's hope BRP will do something clever and not just sit on the tech.

That will be one heavy rear wheel, the weight alone kind of dictate the tire choices. You need the added layers and stronger side walls from a motorcycle/mx tire to have a longer tire life. I know some will say you save weight by choosing bicycle tire, but as heavy as your wheel is already the weigh...

A Domino throttle should work fine but will need a couple of resistors to make the output in the same range as a hall. The microswitch is not really needed. Over a long time, these had a track record of wearing out. There may be some decent quality hall effect twist throttles out there that would b...

Thinking about this a bit more... I have a digital watch good down to 200 meters. I took it apart about a year ago out of curiosity. There was no coating on the components at all. The ONLY protection was the seals in the watch case. Based on that Casio watch, I'd say that even conformal isn't neede...

I actually do have bark busters or hand guards from my 1st Qulbix build I could use, but the problem is that they really make the bike look like a dirt bike and it may increase the chances of getting bothered by police and I think people may also get more mad in the places I ride because they think...

More messing around with Sur Ron on 20S 100A, ASI controller. Hm. From the look of it on the video you can see the power output got a huge jump up to 6.5kw. But to raise the speed seems to take a while? What is the pants in the seat feeling about mid range acceleration with 20s? Any more kick or ju...

BTW. how do you ride in the winter without having your fingers freeze? Gloves don't seem to help for long. Congrats on your new bike, I am sure you eventually will squeeze more power from this, modding or tweaking. For riding in the cold I find there is only one solution on any bikes or even snowmo...

Don't know how it is with Fet's and other controller components. But from the pc and server world they got different quality on CPU's from the same batch. Maybe it is like that for controller components too? What I am thinking of is that if you buy the higher rated components before putting together...

Well look what Santa just delivered... I didn't shake the box but I think there might be a new Sur Ron X in there! http://www.backyardlivingsource.com/blsguest/jq/surron-x.jpg Don't trust santa, he is old and grumpy. Could be a painting of a bowl of fruits. You need to squeeze the package, shake it...

Hey if you can shoe horn that wheel and tire in place great. Should you see any rubbing you could "shave" part of the most sideways knobs, just slightly so you got clearance. Will look bad ass with such a wide tire. And the sidewall height was nice too, should make for smooth ride.

Hard to tell, most parts are not Alta specific and those can easily be replaced. Controller, bms, and motor might be harder. We don't know yet. But worst case, say a melted controller or a motor burns, it will not be the end of world for you, and the bike will not be useless. Just replace with decen...

Will there be enough swing arm clearance for the widest tire?

Offroader you will notice the difference between hub and mid, and you will be surprised by how much better a mid drive handles big dumps and whoops. As for moto front wheelor vs lighter bicycle front wheel many will say it is a big difference, for me not big enough to ride with bicycle wheel as they...

Is there a pic of the flipside of the pcb with thos 6x6 Fet's?

Yeah I agree. Maybe both Rix and the moderators forgot about that thread? I sure did until you mentioned it now.

Anyone know the status on Alta at this time? Did anyone buy em, did they find investors or are they fighting bankruptcy?
I really hope Alta will continue to live on and keep evolving.

I totally agrre AW. There ain't no sure tomorrow as long as they continue to use this practice. Controller can be a dead brick before winter is over and all your hard earned money sunk into the controller will be lost.

Ok, I might have gone overboard in the rant about this. Lets see what the official mobipus says about this. If the time slot is not for all settings or if it is possible to make changes to controller no matter if you are online/offline have swapped motor or whatever I guess it is not all as bad as I...

Well at least I was wrong on that part, good thing they are not charging money for the time slots. But still, all this risk for future changes is in the hand of the buyer, and the controller can be a dead brick if future software changes are not possible to do due to whatever reason. And that is not...

Apologies for the OT below: FWIW, this type of thing very strongly irks me partly because I have a fair bit of software (mostly for music and sound creation, much of it supposedly intended for professional studio / composer usage) that is unusable for this reason. The companies either don't exist a...

a one hour ticket from the factory ? To unlock the top level of settings (which includes the last option for regen to work) a time activated key needs to be submitted, which gives you one hour in this unlocked mode. I needed to use a VPN to make it think I was in Hong Kong to be in the same time zo...
