These bottom brackets where designed to allow you to run standard bike cranks on fazua ride 60 bikes. There are several reasons to do this.
1. It allows you to remove battery and motor to have a more similar bike to regular bike for travel(no need to ship battery) or bike parks where motor isnt needed.
2. Fazua has failure rates that are pretty high so you can swap this in while the motor is out for warranty
3. Just a basic insurance plan for if Fazua no longer supports older motors(currently not an issue)
4. If you want to swap in a different diy motor these are 73mm wide brackets so you can swap in motors like bafang, cyc, toseven, tongshen etc

Specifics about this listing. PLEASE READ BEFORE PURCHASE!!!!

1. I had an initial batch that had an error in threads so they are both RH threads for the BB shells. This is able to be rectified by buying two BSA threaded bottom brackets and using the RH thread cups from each and it will function as intended.

2. These are also set for 52mm width at the rear bracket but final production will have adjustable width. This does limit what bikes it will fit so it is up to buyer to confirm the width on your bike.
Bikes that have been confirmed are Transition Relay Alloy, Santa Cruz Heckler SL, and YT Decoy SN. As new models are confirmed I will update but it is still best to confirm yourself.

These are heavily discounted to below cost so all sales are final. Final design prices expected to be $220-240>>> these are discounted to $75
