The BBS02 was for 68 mm bottom bracket (BB) (or 73 mm with no lock ring) so it wasn't possible for me to space out the motor without really impairing the chainline and exacerbating the symmetry problem. Probably you can overcome the motor hitting frame situation with a 100 mm BBSHD and have the cran...

If you "lose" the front derailleur, you can always shift the chain to a smaller chainwheel by hand in an emergency. However you should have a narrow/wide large chainring to keep the chain from jumping off.

FME = from my experience. BTW, look at the bicyclistxyz web site. There are articles on bike fit by R Schlutz (AIR).

FME (and others that I ride with), switch the pain from knees to the neck area and you'll see why some individuals prefer a more upright stance.

Part of the lack of knowledge regarding "Q" factor may be that many are not aware of or affected by the issue. I was amazed that very few individuals knew there was a difference in distance between the right and left crank arms from their respective chainstays with the BBS02. Seems like the guys tha...

Near as I can determine, the "Q" on my wife's BBS02-equipped with a 68 mm bottom bracket width bike is about 200 mm and the motor housing just clears the chainstays. Doubt that any of Bafang's mid-systems will improve on that.

This won't solve your problem (might make it worse), but even though the "offset" crankarms on the BBS02-equipped bike didn't seem to cause me problems, Lekkie crankarms resolved the situation. Eventually some company will construct a fat bike with a Fazua motor system; can almost guarantee it will ...

You need a different tool for the lock ring on the cassette and the freewheel. Also, make sure the freewheel tool has a large enough hole to fit over the axle on your hub motor (some are made for quick releases and not large enough).

"V" or disc brakes on the front fork will require either studs("V") or a mount (disc) to be welded to the fork or a new fork. Also, disc brakes in the front mandate a new wheel. That wasn't the "homegrown" I thought it was, but the frame looks sturdy and fits you so that's a big plus. I purchased a ...

The Schwinn "Homegrown" (can't tell from the picture) was made by Yeti in CO AIR, and is a great frame. Considering it's your size, jump on it.

If you raise the seat as much as you can, it should be possible to fit a seatpost rack and have room for your bag AFAICT. Seems advisable to have the controller "out in the air" and not susceptible to road debris.

I've ordered at least ten different times from Luna (probably more like 15, but can't remember all of them), batteries, BBS02's , Cyclones and small parts. The one time there was a problem it was rectified quickly and courteously. I met Paul from em3ev at Interbike and he seemed like a great guy and...

On my first BBS02 conversion the gearing was 11-17-28, 8-speed spacing (so, IMO, a stronger 8-speed chain could be used), spaced on the outside end of the cassette which shifted fine, gave a straight chainline (with the middle gear, so the chain was never more than one gear off) and was all the gear...

Went to the Anza Borrego Desert over thee weekend since it was the only place in the socal area without precipitation. 90+ degrees was a little warm though.

IMO, from BBS02 builds, you definitely need to space the support bracket adequately. On one of my builds (73 mm bottom bracket) I tried to affix the "mounting bolt" with Locktite (no room for the jam nut), but it came loose, so I transferred the BBS to another bike. Others have had success, but it d...

Rained for about three hours in the "OC" today; nice little wet down. Maybe some more on Sunday.

Good job; interesting report; I ride MTB and eMTB equally about 2X - 3X a week each. My BBS02 is four years old (so the original controller) and used with the same 52V battery. For me, the programming is fine; using a maximum level three (of nine) on rides of 10 - 20 miles with ascents of 1500' - 30...

Great deal AFAICT since they look to be in good condition and assuming you have a plan for what to do with them.

AFAIK, their sales office is in San Diego, CA; if you can't find a number, probably I have a card from them (would need to find it).

Looks amazing. Great job. I'd suggest a smaller front wheel except your ground clearance is minimal now.

Incredible job, and hope either it helps others by providing a template or you're able to market the concept. Also, (please forgive the diversion) bigwheel, I'm really impressed with what you've accomplished for your son.

Probable you'll need to remove the "lawyer tabs" on the fork too. I would consider two torque arms (look at Grin - ebikesca).

Everyone seems to have good reports on ebikeling and the "1200", which has a 30 amp controller, should go at least 30 mph @ 52V IMO. Luna Wolf @52V, 12 ah (600 or so wh) should provide 30 miles @ 20 mph with you pedaling; faster = more consumption. added after oldwahoo54 - really good point about fo...

Bumps, potholes put a lot of stress on a front fork and the ramifications of a failure might be astronomical. Wouldn't consider anything but a good fork. You can but an excellent rigid fork (Surly or equivalent) for < $75 new or lots less used or used suspension fork for $100 - $200. Why gamble?

Pretty tame SOC. HPC was present with their (IMO) overpriced products, Cake had an exceptionally nice moped for way too much money and M1 Sportechnik had 45 mph carbon jewelry, but still too expensive at $8,000 - $10,000. Nothing exciting at the OEM's, but the new Fazua modular system at <7 pounds m...
