Oset 16/24 Rear Wheel Bearing

[abe75]

Hey Guys,

The rear wheel feels really cluncky and not very smooth, taken the brakes off and still the same, only just thought about it being rear wheel bearing, anyone had any issues before?

cheers

Mine does it but I think what you're feeling is a resistance of the electric motor

try without chain

cheers, will give it a go

Let me know. Thats my theory. Would like to know if I was correct or need new bearings

Hey Greg,

ok didint realise but wheel bearings are loose ball bearings rather than fixed, you would think a bike of this cost would have the more expensive parts, oh well.

so took wheel off, cleaned and re-greased bearings, its not the back wheel bearings, it seems to be the motor bearings, do i even attempt to take that off?

cheers

the motor bearings are not to bad to do. just remove both endcaps from the motor once you have the motor apart also check the brushes are in good condition and slide in and out of the mounts freely, I cant remember what size bearings the motors use but they are a very common size. The hardest part is putting it back together and getting the brushes back in. What you need to do is have some strong cotton to pull the brushes into the holders and hold them in place by bringing the cotton out and using some tape on the outside of the motor endcap to hold the cotton, once you have secured the 4 brushes fully into the holders then you lower that end cap back onto the shaft making sure that the brushes go over the commutator, once you are sure that the end cap/brushes have cleared the commutator slide the cotton out of the motor and this hopefully will release the brushes and then push them into the commutator then just do everything back up. Sounds harder than it is.
