I can ride thru small puddles… But where I come from riding in the rain is like dumping your board (and yourself) in a river…

Sorry for reviving this thread but any plans on releasing the files for the gear drive? Great build btw

ervinelin · January 6, 2019, 11:09am

Having some problems with noise… so will release only when I confident that it works…

So I finally installed the new gears… and man what a difference in the noise!! Instead of some weird howling, it’s just a nice mechanical hum…

These are 60T Nylon gears from KHK

Many thanks to @Linny for helping me machine these to fit the bearing and wheel adapter!

Note, it was a real pain in the ass to machine the gear according to @Linny . I don’t think I will recommend going this route unless you are confident in machining the gear to the specs you need.

you mean the motor gear right?

ervinelin · January 9, 2019, 10:51pm

Wheel gear

Benjamin899 · January 9, 2019, 11:15pm

didnt you buy it? kinda confused.

ervinelin · January 9, 2019, 11:28pm

Yes I bought the stock 60T nylon gear from KHK Japan. Then I got it machined so that it would attach to my printed wheel adapter.

Benjamin899 · January 9, 2019, 11:31pm

ah ok got it.

If lacroix ever came out with a lower cost model similar to this I think it would do very very well.

What do you estimate the total cost for this build was or would be?

ervinelin · January 10, 2019, 10:07am

I didn’t keep track to be honest… And a fair bit of money wasted prototyping too…

ervinelin · January 10, 2019, 10:15am

Gonna need to experiment with them bushings… Was a bit too wobbly when I managed to get some speed…

ervinelin · January 22, 2019, 2:57pm

A friend of mine helped me mill some aluminium motor mounts in place of my nylon ones…

Hopefully the added rigidity will make it run even quieter…

Beautiful, you’re a master

Riako · January 22, 2019, 5:43pm

Awesome work done once again sir !! Hurry a little video then

captclearleft · January 23, 2019, 3:34pm

Very Nicely Done Sir!
Thanks!

ervinelin · January 24, 2019, 11:19am

Haven’t had the chance to really ride it yet… Only had time for beauty shots…

Mich21050 · February 12, 2019, 6:50am

Sorry for reviving this old thread but I really want the stl files for the gear drive I’m talking about the tb 218mm and aliexprss version

ervinelin · March 10, 2019, 10:26am

Board was shelved for more than a month after waiting for my replacement battery.

Upgraded to 10S3P (from 2P) very happy with the improved range, it’s now more than enough for my usual ride. Previously I had to sip amps towards the end of the pack…

rey8801 · March 10, 2019, 12:09pm

It’s really nice. This solution would be the only one I would consider for a AT build since it still looks manageable in size. I mainly use the board to go around the city and an AT solution would help for sure against the bad road.
