1 kit is left :slight_smile: For someone who wants to go ride now and don’t want to wait for summer :slight_smile:

Everyone else start saving money for the group buy, after first testimonial / responses we will start a group buy thread in pre-order style we collect money and will be making first batch which should decrease the price if we collect enough of people :slight_smile:

Hey, guys after @deckoz struggling we created a new design which should solve a lot of problems. It changes everything mostly:

  • 3 gear system
  • Whole aluminum case
  • 17mm ground clearance

What struggles did @Deckoz have?

Have you solved your tolerance issue with the wheel bearings? I bought a set of cnc hubs from you because my bearings fell out of my Tramps superstar hubs. I mentioned this to you dude before purchase. I was under the assumption that because you did not anodize your hubs the fit of the bearing would be “press fit” but it falls out… Not good enough dude… Unhappy customer :frowning: your solution was to loctite… something that should press fit. @Moderators I already tried to work this out, so buyer beware! dude is sloppy!

What has anodizing to do with fitting a bearing?

What? I explained why tolerances variates because of aluminium, and told that use green Loctite which is made for glueing in bearings it’s better than bearings compressed/squeezed inside.

About trying to work out what did you tried to work out? Because your last messages said I’ll let you know how the rest go…

@e.board_solutions anodizing/painting grows on surfaces.

is it so much? If it grows it makes the bearing sitting tighter no?

Not true. Anodizing take away material. I have talked to a lot of people (engineers and mechanics) and what they all said is that thermal installing of bearings is the best way. warm up the nest and cool down the bearing and it should just fall into it’s space. Once it reach equal temperature it should be nice tight fit. Your new solution looks complicated and noisy probably and more resistance… for high power setup I would go with 15mm wide belts and next stage is some kind of direct drive I believe.

sorry mixed paints grow/anodizing takes away

I agree with you but how many has access to like blow torches and etc, we use green Loctite which was made exactly for glueing in bearings:

LOCTITE retaining products secure bearings, bushes and cylindrical parts into housings or onto shafts. They increase maximum load transmission capability and uniform stress distribution and eliminate fretting corrosion. Applied as a liquid, they allow 100% contact between mating metal surfaces, eliminating the need for more expensive designs, time consuming machining and even the use of mechanical methods.

More than enough… http://allegro.pl/palnik-gazowy-zapalniczka-zarowa-zapalarka-grilla-i6280344677.html#imglayer

Let’s say it works both :wink:

well without anodizing, & kugies hubs the bearings fall out… just like my trampa hubs… trampa claims it is the anodizing that makes it happen… I spoke to kugy about this before purchase. In fact this was the reason I bought his hubs. Just know they are not press fit. They can be made press fit, Like every motor I have ever bought, his hubs are not, the tolerances are sloppy…

As you havent talked that you didnt liked or etc, not even mentioned it. You could had wrote me down, I would had taken them back and returned the money but you didn’t did anything and now wrote that you tried to work out this and u haven’t had luck :slight_smile: @Moderators can look up my messages. Please move this discussion to its appropriate topic.

I agree with @Cobber , it’s common design practice to have the spinning side of a bearing to press fit, Loctite is mostly used together with a press fit or to save a piece that was made wrong, not to be used by design

@cobber I just talked with my father he said that when he shipped the wheel hubs for you none of bearing even fit into them without really hard press. Also he said if you don’t like it and want your money back, don’t even bother shipping them back just cut them in half or hammer them so they would not be usable and send pictures to prove it. We will return the money back. As shipping can be expensive for you. :wink:

Because the way you started this sounds a bit sketchy :slight_smile:

@Pedrodemio I agree with you :slight_smile: Next one will be shipped with bearings needed to be pressed in so they wouldn’t fall out.
