Would these tires fit the 3d printed hub? https://www.aliexpress.com/item/6x1-1-4-tyre-for-mini-scooter-with-butyl-inner-tube-good-quality-Pneu-6x1-25/32740915476.html?ws_ab_test=searchweb0_0,searchweb201602_3_10152_10065_10151_10068_10136_10137_10157_10060_10138_10155_10062_10156_10154_10056_10055_10054_10059_10099_10103_10102_10096_10148_10147_10052_10053_10142_10107_10050_10051_10172_10084_10083_10080_10082_10081_10110_10111_10112_10113_10114_10181_10182_10078_10079_10073_10070_10123_10124,searchweb201603_16,ppcSwitch_5&btsid=2ce02bcb-2759-4635-a3f5-28bd66fb74e7&algo_expid=cb8d8a8d-e82d-4f09-9041-abdf962f2df7-13&algo_pvid=cb8d8a8d-e82d-4f09-9041-abdf962f2df7

These are 1-1/4inch in width - the hubs were designed for the wider 2inch ones. It could work but I am not sure.

Got the tyres quicker than i thought. Just waiting for the 3d printed parts now. Might be late next week I get them printed (i have to wait a while, but i donā€™t pay a penny so canā€™t complain). How are they holding up for you @Maxid?

I am waiting for my pulleys to be printed. I kept the tires inflated on the hubs and so far all of them are holding up.

Iā€™m planning on just replacing my 2 front tyres for testing. I can still use psychotiller hubs for the back powered ones.

Can you design pulleys then? Any experience with Fusion 360ā€¦As I canā€™t find a way of designing the teeth and itā€™s annoying me

I am using Inventor for my CAD. Pulleys are made via this: http://www.thingiverse.com/thing:16627

I used that thingverse pulley creator, and got as far as creating the pulley in OpenSCAD, then Iā€™d export it into fusion, but it always imports as something that I canā€™t alter (I wanted to punch some holes for bolts to go through, and maybe add/reduce the thickness in some places)

That inventor thing seems to cost money, think iā€™ll invest some more time in Fusion as itā€™s pretty good, and also free :slight_smile: (also Iā€™ve found CAD ainā€™t that easy to learn, so Iā€™m not enthusiastic about learning another program)

you need to convert the stl file made by OpenSCAD before you can use it in any CAD software. Inventor luckily has a conversion feature.

53

Howā€™s the balance of them?

54

Very tempted to try nematic tyres finding my current setup very bumpy where I live and a few curbs to high for me to go up so going to these would be a good option. Let me know how they go would be good to use the same bolt holes to attach a pulley to as well or combine the inner tyre brace and the pulley into one pice.

What do you think I am doing :wink:

Nice what sort of teeth count is that ?

57

I think 35 teeth

58

Yep 35t - together with the 15t on the motor pulley at 6S and 140kv motor I am going for a 30km/h topspeed

59

THats not far off what I run now but need to find some of the dual pivot like evolve use to help convert easy from street to mtb

@maxid: how long and hard have you ridden your ABS-hubs? I did a test print in my scrap PLA just to check that the conversion to STL in fusion360 didnā€™t mess anything up.

Just wanted to know its worth printing four hubs in ABS.

I just got my printed hubs today :slight_smile: Waiting for bearings and bolts that I forgot to orderā€¦Should be testing them at the front of the board next week

Not at all until now :frowning: - so many things to do and after reading about a recent incident in which the police caught an esk8er not far away from where I live, I am reluctant to use my boards right now. I hope @riva_00 can give you more details once he tested them on his board.

Ahw, that sucks. Is there a translated article about it?

Btw, what infill did you print with? 100%?

I posted it three weeks ago:

infill I donā€™t even know - I just sent the files to the guy responsible for our printer and he got me the parts :wink:
