Best wheels for sumo robots! Before we were using lynxmotion sponge wheels, but this wheels jumped robot's power to very high level. No need to extra universal hub. They fit directly to our titan 1000 rpm motors.

I use it 4 wheel line follower, they track the route great. And stackable design is very usefull. I tried 3-3 wheels at each side, but unfortunately it made a little weight (traction and manuevering is increased where as)

I am using them at my minisumo (as usual). All opponent robots defeated easily. They hold the ground very well. And don't need to use any extra coupler, hub etc.. nice. I clean with alchol and voila! very slick traction.

This ebook opens a new page in my sumo robots. That made me notice many many mistakes. Getting help from a JSumo, for new projects also priceless.

Recommended!

When will be restocked? I bought last piece months ago and using. For my new project I want to buy more but still waiting. Please be fast Jsumo :)

I won Robofest 2016 Robot competition 2nd place with that chassis. Recommended to all project makers.

I liked the versatility. Gives low COG to robot. Only suggestion is why you don't designing similar chassis for 5 sensors?!

Better price than Pololu. We use it for line follower and mini sumo robots.

I am seeing this gear bundle at lots of Mexican robots, stop selling! :)
