Sascha, Lets start from a better spot. What kind of performance do you want out of this dirt What level do you ride. These are the starting blocks. Alta built a 260+lbsbike with 40HP (using I think Panasonic cells). When they went to the Sony VTC6 cells they were able to get 50HP. These are...

Robert, I can say right off it takes quite the mechanic, fabricator, crafter to build an Electric bike or vehicle from scratch. Not to try to discourage you there is a lot involved. I have built from scratch, and it takes a lot of time and expense to build that way. What Mark has done, has...

Makiman, Yes I know the guy at XtremelectricMX quiie well. His name is Mark, and he lives in Florida. I am in Lake havasu City AZ. He has one for sale right now on Ebay. The same model that I have. I have it running , but with a temporary battery ( only 200A) Here is a youtube of it...

I have a Sevcon Controller on my dirt bike. I was introduced to A gentleman named Richard George to help me get my system up and communicating. The friend who recommended him has used him numerous times, he is good. He used to work for Sevcon before it became Borg Warner, and he can work with...

Thanks Rashid510. I didn't know there wasn't termination in that adapter. DigiKey was out of stock of that item and $33 plus shipping. Amazon had one for for $8 , and will be here in 2 days. Plus they had information on the product. But thanks for the info. I don't have the DVT software...

The owner came and pick up his KX100. He loved it. It's heading up to No Cal. It will be at Hollister in no time. The picture on the back of the RV is of The Over Forty Club at Hollister, and the bike going home. Here is one of his first rides on it

I just bought the IXXAT tool from Digikey for $343 plus tax and shipping $373 total. I just got it and have not got the DVT software yet . I will report once I test it. I am working on a 2014 YZ with the ME1115 motor in a billet gear box, and Sevcon.

I got this Kickstand for my YZ250F and it is super. If the footpeg mounting bolts on the Alta are the same as the YZ250F 2008 ( my bike) this one is great. I don't know if it will clear the swingarm. it clears on my YZ just fine...

@riverin, On some of my earlier batteries, I did what you did, used the BMS for Charging only, but the last one I used the ANT Smart BMS, and used the BMS for both Charge and Discharge. I used the 300A model from ElectroandCompany and for it's size it does an amazing job. but I don't know...

Interesting that you are looking at the Far Driver controller. I am too. My Kelly is trash. just too many other project going right now. The guys at Electro and Company have had some experience with the smaller Far Drivers. Let's keep in touch on what we do and find. I was looking at the...

I just installed this motor , the V3 in a KX100 ( in this forum KX100 Electric Pit Bike) with their controller VOTOL EM-150SP, programmed by ElectroandCompany.co, they do it for a few hundred buck.. It worked so sweet out of the box. A little over 210A 's. Mighte in Ireland (MightE MX –...

So @riverin have you rebuilt you bike yet? Did you get CSI Canada to figure out the cause of the problem with the batteries? Were you able to salvage a lot of the parts? This home building battery maker would like to figure out as many clues before anyone else has a similar problem. We are...

Thanks for all the help building my KX100. I just posted it here on the AltaOwnersForum "KX100 Electric Pit Bike" You have been very helpful. You make these builds really easier. The V3 motor and Votol controller with your programming really is smooth and fast!!!

I built this for a friend in about 6-7 weeks. It started life as a 1991 KX80, was converted to big wheels some where along the line. My friend put new tires on it and had the suspension gone thru. Gave it to me. Now after he get it back, he is going to ride it a bit and the tear it down and...

My friend rode one at Hollister off road park. He was not impressed. Uncomfortable riding position, and the price is stupid for what it is. They are trying to get them for the rangers to ride. The SurRon is so much better for a lot less. or a regular pit bike modified to electric by or with...

Great job Dain. I know how much wok that is. I wish, like you say if we could get one manufactured, and available for 500-600 bucks. That would make builds easier. In the last 5 -6 weeks I built this from scratch. A KX100 Pit bike with a QS138 70H V3 gear reduced motor. What a blast to ride...

As far as resoldering the wire bond back on, some one mentioned lower temp solders. The Tin / Lead 60/40 melts at 374 degrees. ( you can get it at Ace Hardware Alpha Fry 3/4 oz Repair Solder 0.05 in. D Tin/Lead 60/40 1 pc - Ace Hardware). Lead free solder melts at 430 degrees. I built a...

I found this on Thumper talk. An interesting thing. That is one of the most common comments, " But I love the sound of a Performance ICE motor!!" This sounds like you can put any type of sound in your car, or possible outside if your trying to impress some... I forgot the link. αlive -...
