Width between rear dropouts

[NOTTNICK]

Hi,

Anyone who read my desperate post on Monday about the rear motorised hub on my wife's bike may have an idea about this already.

I hope this is OK on a new thread.

I have determined that the malfunctioning hub is generic (brilliant advice from this forum, thanks), so a replacement motorised hub should plug into the current control / battery system. It is a standard 9 pin connector.

Unless I can mend it myself (tools arriving tomorrow) - unlikely. I shall order a new hub and get the wheel rebuilt. My current hub uses a cassette.

The current spacing between my rear dropouts is close to 145 mm. Can anyone advise if this is a standard width?

My priority over cost is time (we want to get out again). The quickest delivery I can find is this one on Amazon, about one month I hope that is realistic - others are up to 3 months!!

Is anyone able to advise me if that hub would be the correct width?

Any advice really appreciated.

With side screw plate these are quite simple to open if they are not rusted by being wrongly fitted or water has ingressed.
Used a rubber hammer if you have tap the axle end on the non cable side or a block of wood and hammer.
If having any issues ask first.
There is little inside to go wrong so either might be chewed/worn nylon gears or bearings.
End drive bearing usually on the LHS is press fit and drives out easily with suitable drift (I use a spanner socket of the correct size). There is a main centre larger dia bearing again not hard to leaver up using a pair of wide blade flat screw drivers opposite each other going around said bearing and gently levering. Whilst at it check the hub bearings for the gears for roughness (usually a pair).
The bearings should have the id number marked on them and are readily available to get hold of.

About 145mm is fairly normal for a cassette motor. It's probably closer to 142mm. Some are a bit narrower, but that won't give you any problems when installing, nor riding.
