Greyborg Cromotor Hubzilla motors, Sold Out

[RAPHZ400]

I'm happy with the new

[Indubitably]

I'm down for one if there are any left after tending to early preorders and whatnot. In a 14 inch dirtbike rim with a nice fat tire this motor would look right purdy on my rediculously over built 70lb full suspension recumbent. Not to mention that I have an 18 fet lyen controller that has been itching for a good modding for some time now, and this looks like just the excuse to finally go through with it.

What is your source for the 14" rim and is it 36 hole? Im looking for one myself for a fast wind motor particularly if it will take a 14" road tire. What will the overall height of the wheel and tire be?

Hi, yamaha yz 80 motorcross bike. They are 7mm thick and cheap secondhand from wreckers. 36 spoke.

Well, the rim is easy enough, that you can grab off of eBay from any dealer of chinese dirtbike parts ( I tend to favor the "chinese motor parts" eBay store but I think they may only sell built wheels). There is actually a whole wealth of cheap super light generic chinese dirtbike parts that are a little too flimsy to be taken serious by any hardcore motocross buff, and way too over built for any serious bicyclist to consider weighing down their 17lb $3000 carbon fiber tour bike with, but perfect for people like us who are building rediculously over powered ebikes. I just put a pair of dirtbike forks on my semi-recumbent cruiser build, and although the extra 12lbs stings a little on the hills, there is nothing quite like 5+ inches of travel to put the fun factor back in your daily commute (curbs have effectively lost all meaning to me at this point, and thats running a 5302, who knows what shenanigans will ensue once I get my hands on something with even a modicum of low speed torque). I figured, hell, at $60 for the pair, I can always put them on a different bike if I don't like them on this rig.

At any rate, my plan was to rig something custom out of aluminum plate since your spokes would be probitively small in a 14 inch (read 16" in bicycle terms, with a tyre my total wheel diameter should be about 18") dirtbike rim. If it weren't for the motors coming out cockeyed this run I probably would have experimented with attaching the tyre directly to the hub itself, but that will likely be a bit difficult at this point unless I want to upgrade to a motorcycle swing arm to give myself some play in the wheel position. As it stands, I'm still looking at some sort of custom hack to almost directly interface the rim with the hubany way I slice it, and the cromotor will probably obliterate the first few attempts, but this kind of thing is not that uncommon with scooter hubs so it should be doable all the same.

You can most likely do your interface you were talking about, the flanges are now centered due to the new custom made 16mm axles Greyborg designed to solve some problems Here is a picture with the new axle installed.

Sweet, looks like I wasn't paying close enough attention to the updates. Yeah, in that case it should be a lot easier to rig something up that will either keep a very tall baloon tyre snug against the hub or the rim snug against the hub with a smaller tyre. Since we don't have to dish the wheel any more, with the right lining/interface it should be possible to pull the rim taught against the hub if we need to. If the spokes don't need to bear any serious compression load, it should be much easier to fool around with how we use them.

I am glad those changes were made. I don't want to wait any longer! Got a 29er Sun MTX 33 for this guy. Kinda wish I got the 39.

Any chance to still get in on these at the reduced pre order price?

And what would be the chances of getting a few motors directly shipped to Australia?

[chroot]

You can get it from Hyena (Jay), he is going get some hubzilla motors for Aussie region since he was upset for being ripped off from Crystalyte Kenny. He is going different route for better quality control from CroMotor folks are far best reliable reputation than Crystalyte.

I was the one encourage Jay to get CroMotor line for Aussie regional.

It would save your shipping costs.

You need to contact Accountant to find out who to purchase from. I'm only handling USA and Canada.

Just saw it looks like Hyena might be handling Aus.

[gensem]

If its really Hyena, Aussies are in good hands.

I cleaned up my first post to hopefully cut down on some confusion. I'll let everyone know on here as soon as the motors are on their way to me and then once I have them packaged up and ready to ship. People who have emailed me will be notified before I update this post so they will have first dibs. I should have enough to satisfy demand but I've been getting several requests the last few days so the amount left is dropping.

[zombiess]

Got a tracking number, motors are starting their journey to me today or tomorrow.

[chroot]

Nice nice!

[RAPHZ400]

Very very good news

[hillzofvalp]

and?

[zombiess]

And delivery is expected around the 15th. I'll still need to check and repack the motor though so they should be shipping out within 1 week of me receiving them.

[hillzofvalp]

Cool. Are u having a semi and forklift come over?

[hillzofvalp]

do you think the cromotor axle is big enough to be drilled once (.0625" diameter) near the shoulder on each side? This would make retaining safety washers much easier/safer. In practice with a strong enough pin there would be no need for a safety washer and the pin's circumference would lie directly in the same plane as the shoulder of the flats.

You might want to PM Hal9000v2.0 with that question as I'm not quite sure what you are talking about or why you would drill the axle so I'm not qualified to answer.

[hillzofvalp]

Are u using a washer against axle shoulder or the bare shoulder? If you don't use a washer, the shoulders have a tendency at least on 14mm axles to dig into the dropouts, eventually wedging them apart.

On my current motor, yes, on the freewheel side against the axle shoulder (what's a bare shoulder?) to prevent it from binding. On these new motors I don't know because I haven't had one on my hands yet.

Posting some pictures of what you are referring to would be very helpful in me helping you. Did you PM Hal your question, he can probably answer it for you since he designed these axles himself.

[hillzofvalp]

Bare boulder implies not using a washer at all. So you do use a wash,m but only on one side. Why? Side question: does the washer pancake out? Is there much more surface area on the shoulder that this is less of an issue with the 16mm version?
