Hi e-riders !
Ok, so… It almost looks just like I want (except there is still no enclosure ^^)
But I’m a bit disappointed here
I would like to upgrade from urethane wheel to air tire,
so I buy this BoardBumper kit and well follow the video setup (even if I’m not at my 1st build I am a good student!).
But nothing goes easy or aligned correctly with itch other or spin round or fit well.
The wheels bearing aren’t sitting properly in this plastic adapter and there is only some mm sit and the end of the bearing is just not supported (in the bearing adapter) … weird!
you could see the gap
You can make the rim not spinning around on the trucks just by hand, so I couldn’t imagine when you ride on it
When you set the wheel drive is not and can’t be aligned to motor gear, due to design :
- Cause this little 5065 motor got an hole (not keyway) to set the grub-screw in place and hold the motorgear fix on the saft.
- Then the wheeldrive that come on the 10mm axel of the Supercarve hanger can’t be moving forward more than that on the hanger.
I set all like in the vid, then make the wheels spin freely and shaking everywhere making the board bounce ^^
Belt move and come naturally in place, but not the good one :
same on the other side
Always got 3-4mm of the belt outside the wheeldrive …
And it start to rub against the collar of the pinion (sprocket) and the mount …
But here I could solve the issue with another motorgear.
Another big problem with it … the tension of the belt is no longer adjustable !!!
the motor gear is to close to the wheel drive and there is no space to adjust it. Really weird for a AT kit (even if there is many tooth engage) !
I guess this isn’t ridable.
I let the dealer shop and BoardBumper know about the issue, and the response is :
The customer has the gear spaced to far out. It should be aligned with the motor gear. He needs to remove some spacers behind the drive gear bearing.
haha … yes, it’s why I emailed us … and like shown in the picture above ( and that I joined them) there is nothing removable to make some more space from the wheel side.
Also the aftermarket motors and motor gear he is using has different gear placement compared to stock motors and out motors. It causes the motor gear to sit to close to the motor mount. This causes issues trying to align the motor gear with the drive gear. For the belt to run true they must be perfectly aligned with one other.
Ok, so that I already know > to change my motorgear but nothing about belt tensioning.
I got no problem with the Evolve street kit, 38T wheel drive this this same Evolve-like setup…
Did Evolve motor get a long shaft and a keyway? Can one adjust the alignment of the pinion on the motor axis/shaft with the 66T AT kit? Make the belt tensioning possible?
I answer them, since no news, I transferred again my email back on Wednesday.
Plus they did not respond to my cancellation request.
This kit just didn’t worth it …
I make 5km and the belt shred so much that it brake, let me go home with one little motor and the other one spinning freely (yes, I know, I wouldn’t walk all the way and it was the slave motor).
I will put my 107mm back !
too bad I really like how it was looking …
