GNG Gen2 mid drive with Fat bike (100mm BB)

[crashalot]

Hi Guys,

I am thinking of going with this kit on Mongoose dolomite but this one is only for 68mm BB.

If I buy replacement BB cassette that is 100mm will this kit work ?

thx

I sort of have the same question. Looking at the GNG kit it would seem the freewheel slides over the square spindle. If the Dolomite has a conventional square spindle I would think the GNG parts may fit on the stock BB.

Anyone know what type of BB the Dolomite has stock?

I love my home built Ebike but it is pretty out of reach for the majority. I was thinking a mid drive fat tire would be a nice simple way into the Ebike world.

I'm pretty sure with a bunch of spacers for the motor housing and a 100mm square taper bb it would work. I mounted my old gen 2 on 100mm by cutting the motor plate and adding a bunch of washers to space it out.
