Title: Electric conversion
Post by: g4s on March 18, 2025, 05:02:37 AM
Hi y'all, at the risk of being run off the site... I am thinking of converting my K 75 to electric. I live off grid and have upgraded the system and have acres of surplus power.
I am meeting lots of resistance to this idea which tells me I am on the right track (if a not too well beaten one.)
Is there a thread on this site relating to this?
I am going to get an engineer to do it here in Aotearoa/New Zealand.
I would be grateful for any advice.
Chur.

Shouldn’t be any reason to be against another form of motor-vation. 🙂 You might check out Marshall Hewitt on IG. He has some conversion experience.

Sounds like an interesting idea, but in the time I've been hanging around K Brick forums I haven't seen anyone build an electric bike out of one.  The wildest I have seen was someone who put a turbo diesel in his bike.

You might be better served by seeking out electric conversion information directly.  But definitely, when you begin the conversion, start a thread here to document your project.

I have seen exactly 1 electric k bike. It was on one of the Facebook k bike groups. Here is a writeup on the bike, and the dudes name is in the article in case you want to track him down

Cheers folks for yr replies.
One of the engineers I reached out to came back with grim news. New Zealand's Land Transport Safety Authority has rules about exceeding the GVM (Gross Vehicle Mass?) for modified motorbikes.
Bit the end just an obstruction.
The K100 sooprvylyn referred to us flash. I'm less worried about looks just so long as it works.

Ural had a 1 off factory E conversion, rave reviews but haven't heard much of it lately.  It used the Zero electric motorcycle battery and motor, might give you some ideas https://www.imz-ural.com/electric

You already own a hybrid. K bikes burn both gas and oil.

For a while mine was electric, but very short range (about 5 miles, just far enough to be a pain), until I figured out that the alternators rectifier had died, she ran purely off battery....

Indeed there are a few people that have done it, marshall hewit being the one with the biggest range on a single charge (160 miles if I recall correctly and a decreased top speed at 120 kmph).
I think he started pre-orders for them as well, converting 5 at this moment.

Dont let your dreams be memes.
Also post the progress and process here.

Whichever direction you want, please keep the 4-pin as an homage to bricks of yore.
