Did you buy the pulleys directly from Vex robotics? When i checked they only offered Fedex shipping to my location and it was over 100USD as I am outside the US. I sent them an email but no reply.


#122

the downside to buying stuff like that, as i hope you’re aware, is that parts are next to impossible to find, QC is non-existant, and it could last a week or last a few years… i dont mind spending the money on a product if i know it is going to last.

as for the NESE modules i hear they are good, but for my personal taste they’re too bulky… im building a 12s4p into a Hummie deck single layer w/ b,s and only need a 1.3cm-1.5cm deep enclosure


#123

yes, airless, solid


#124

do sell some with air?


#125

possibly, think this wheel have another tire version, need to check. why? tire will got flat tire, dose solid better?


#126

Tire will have less rolling resistance and battery will last longer. One can solve problem of flat tire with tire goop/ tire sealant.


#127

it is mainly because of comfort.


#128

Please do that! :wink:


#129

If you guys didn’t know, I built a geared drive for this 6x2 wheel.

More info on my build here.

Problem I am having is these wheels drink battery juice for breakfast!! I was expecting 20km range on my mini AT build, looks to me like I will only get about 15km.


#130

This looks awesome. I might do it if I am not satisfied of my belt drive.


#131

I love how quiet belts are but after changing one of my esk8 decks to geared, I was a convert.


#132

Did you find out What was the cause of the rolling resistance you mentioned in your thread?


#133

How about you, do you find it difficult to push with those wheels? I am still waiting for mine to arrive and I hope it is not a big issue.


#134

Might be one of the tubes leaking a little but seems like it’s just bad overall because of the wide contact patch.


#135

Impossible to push like a manual skateboard, I tried before installing the drive. Went one small round on smooth concrete already worked up a sweat.


#136

Damn, I better not run out of battery then. :sweat_smile:


#137

I bought them from vex in the UK, shipping was reasonable…


#138

So I ran out of battery… had to do the walk of shame because it was easier than trying to manually it manually…


#139

well getting 15km out of a 10s2p with 6240mAH is very good imo.


#140

I remember from my evolve bamboo gt with AT setup it had very high rolling resistance, I mean I couldn’t push it easily like street setup. After a push it would stop in 3-4 meters.
