Hi everyone, just finished my new creation. BBS02B with a BBSHD core. A few mods were needed but it worked out in the end. Since I was able to bolt up a BBSHD controller housing to my BBS02B case I figured I would also be able to put on a BBSHD motor. Since I was already planning and purchasing spare BBS02B parts I figured try a BBSHD core. If it doesn't work then Ill exchange it for the right part. After removing the rotor from the HD core and bolting the core to the BBS02B housing I figured the only thing that would be different would be the rotor shaft itself. After a couple trips to my local machine shop and 25 bucks later all they needed to do was replicate the BBS02B rotor dimensions to the BBSHD rotor, both rotors were almost identical. After shaving a few mm off the length of the shaft and helicoil it bolted right up. The left side crank predictable hit the motor since the HD is way longer that the 02, I had to modify a crank that came with the bike and grounded down a few mm of the inside of the crank arm itself till it cleared. Now the countdown is gonna be how long the nylon gear lasts. I have a spare so im trying to beat it up as much as I can, we'll see.
On another note...... I use a PR on the BBS02B and now this BBS02HD. Since my commute to work is 8 miles each way the BBS02B got nasty hot(burnt finger hot) at full power but this HD barely gets warm at full power the entire way. Plus I didn't want to give up my perfect chain line in getting an actual BBSHD.
11/20/2018 UPDATE.... Shes been fantastic, pulling strong with no weird noises whatsoever. Going to and from work (8 miles each way) produces noticeable a lot less heat than the BBS02B motor.
11/27/2018..... Still going strong. No issues whatsoever. Full power all the time to and from work and its perfect.
12/17/2018...... Nothing to report still going strong, full power 90% of the time.
12/25/2018..... I broke 2 teeth off the big gear, I'm surprised I broke this part so soon.
01/9/2019...... Installed new gear from Luna and continues to run strong.
03/26/2019.... Running 20 miles a day now.... to and from work. I've installed it all on a new(to me) 27.5 Schwinn Al COMP and she's been great. Ive been swapping the BBSHD and BBSO2 cores a few times a moth to ensure everything works and it does.
