tahustvedt said:I went for a little test ride just now. 28,9 km long and 324 m elevation. I used 4.1 Ah of 6 Ah available. I rode at assist level 3 and tried my best to apply as little power as possible myself, and just kept the crank spinning to let the motor do all the work, as a worst case range scenario. The peak power was ~560 W according too my Watts Up. Continous power seemed to be at 230-250 W when I was in a steady climb.

Although if you're an old time bike mechanic like me, you can tighten the inner lockring with a stout flat screwdriver and a mallet... Just be extra careful about your paint job. ( older Bafang units have both lock rings notched at 4 places... Newer ones have the 4 notch inner lockring, and a more decorative black anodized 'cover' lockring that has the splined surface of a shimano BB set... If you wrap the aluminum lockring with something like cloth bar tape, you can use a channel lock to tighten that if you're careful )
Other than that, all you will need is a set of metric Allen's, and something that can cut off excess zip ties for your cabeling.
The Bafang spindle fits inside the BB VERY SNUGLY. At first I though I would have to sand or file it out a little.... But its just that tight a fit... Needs a little careful alignment and steady, even pressure to slide thru.

tahustvedt said:It's the 250 W motor and 36 V battery. I have not changed the advanced settings for assist. Advanced setting was set to 3 as default when I looked. I have three assist levels, plus "zero" assist. I have the C961 display unit.

Its just a standard Shimano Bottom Bracket tool.
shanman3us said:OK. Well that sure seems to be good use of the power. It also appears to be quite a clime and then to only use 4 AH. I'll be interested to know what the settings are if you ever decide to make/purchase the programming cable to at least see the programming that is there. Being able to make those kind of changes can make a big difference and has made my riding experience change from fair to excellent.

Nice build. If you want the motor to cut with braking a HWBS should do the trick.

Bafang are telling me that the new 25A BBS02 controllers are due to arrive into their factory next week. After that motors will need to be produced using these controllerss. I would expect that we can receive some 750W 48V BBS02 kits within ~3 weeks from now, possibly sooner. Once a firm date is available, they will be made available for purchase on the website.
