Specialized Carbon 'Fatboy' and the Bafang BBSHD

[teb1963]

Hi,
I just found this adapter, is this what I need for a BBSHD on a PF30 Fatbike Pro that is 100mm wide

This is my latest upgrade a new rear fender and a topeak super tourist

Mostly for weight but if designed right it can flex for added suspension whereas alloy is just stiff. Still not as good as steel forks. A lot of engineering goes into carbon bike components so the flex well and absorb a lot of road bumps and vibration. When I see cheap chinese carbon clones I doubt they have those characteristics.

I curious about what carbon does for a fork. Different performance characteristics or just for weight and strength?

[Louis]

Thanks, thats an easy home made tool, a great share!

You might want to cut those zip ties flush with a nipper, especially the ones on your seat stays, they can be sharp. Ask me how I know this.... lol.

Nice ride

I have checked

and the frame is a lightweight alloy but the bike originally came with carbon front forks.

It now has Bluto's but the bike was called the Specialized Carbon Fatboy

[Louis]

I'm curious too? Having no experience with cabin frames, the BB looks like it has welds?

[PoweredRide]

Nice bike. Just curious. Where is the carbon?

The PF30 Adapters are a push fit
o i bought a simple tool to get them in properly off Ebay



so they are very tight

I have had no movement so far

[Ade]

The PF30 to BSA adapter(s) you bought - do they just sit in the BB shell? How tight is the fit? The "teeth" of the motor bracket bite onto the adapter rather than the BB shell, right?
I just wonder if they add any support at all to the motor to stop it dropping down once the lock nuts are tightened? If not I guess you need to really righten those lock nuts.

So Took it out for a shake down

Apart from

Seat needs angle changing
right gear lever alignment
right brake leaver alignment

derailleur tuning

all seem mechanically fine.
will check all bolts next

main Issue is the battery cuts out under load

I have to disconnect completely to get system to reboot

I have had this with the battery before
but 5 times on one ride is a bit much and not all under load too

Very nice, its good to see some really innovative professional looking ideas coming along on this forum.

[SulshyBoi]

Its Home Made

A Neoprene Yoga mat and a couple of Roof rack straps Its Hand stitched at the moment but i am going to take it ti get some machine stitching for strength.

cost me £2 for mat and £4 for straps

Ohh and a box of plasters for all the holes in my fingers

But does cover the Triangle battery nicely

[Rodney64]

Nice write up SuishyBoi, good to see a well documented build. Where did you get the battery cover?
