BBSHD - considerable drag when unpowered?

I've had a BBSHD installed on my cargo bike for about 3 months now, and while I like the system, when it's unpowered (ie I have off or no assist), there seems to be a tremendous amount of drag. When I had this bike set up with a geared hub motor in the front wheel, I could ride it unpowered with no ...

Bafang BBSHD DPC18 display question

I have the Bafang BBSHD and the DPC18 full-color display. I've attempted to tweak some settings like clock, number of assist levels, etc. For some reason if I set assist levels it defaults back to 5 and while it records total mileage and saves that (trip mileage), the assist levels don't seem to sta...

Re: Bafang DPC18 display - battery life - when to charge

I do know there was an issue with the C965 display that it would work with a 52v battery but didn't actually support it, so the battery meter would show it being full for ages, then when it finally started going down a few bars (I got 80-90 miles - can't remember how much it was), the battery was si...

Bafang DPC18 display - battery life - when to charge

When I bought my Bafang BBSHD for my cargo bike it came with the C965 display which I quickly learned does not register proper battery life for 52v batteries. I now have a Bafang DPC18 display which does in fact properly register the voltage. Since installing the new display with a fully 100 percent...

Re: Getting amazing range with BBSHD or faulty display?

I just decided to go ahead and order one of the Eggrider displays. Seems like it's even more functional than the various other full color Bafang displays, and with the phone app/bluetooth connectivity it will allow for easier adjustment of display parameters and I guess even tweaking motor settings ...

Re: Getting amazing range with BBSHD or faulty display?

Yep - checked my docs on the battery. It's a 14s 52v battery with 33g Samsung cells - 28.3 amp hours. I guess if I want *real* data on the battery/state of charge/watt hours used/etc, then I probably need to buy an Eggrider.

Re: Getting amazing range with BBSHD or faulty display?

Now that you mention it, the pack does fully charge at over 52v. I'll have to dig out the testing documentation from when I bought it. It may in fact be a 52v pack. I'm also going to have to dig through the 965 display docs and see if I can find those other settings. I only did enough configuration ...

Re: Getting amazing range with BBSHD or faulty display?

I should clarify since someone mentioned "CA." This is a Bafang BBSHD with a stock C965 display. It doesn't show anything to do with wattage output or watt hours. More than one person has suggested getting an Eggrider display as it's more accurate and programmable than the stock displays. I've resis...

Getting amazing range with BBSHD or faulty display?

So, I ditched my hub motor and installed a BBSHD on my bakfiets cargo bike a couple weeks back. I have over 80 miles on the odometer now and the battery gauge on the C965 display is showing no indication of going down - like the battery is barely even tapped out. The display has those bars that equa...

New- Lekkie Buzz Bars offset 170mm

Got these with my Bafang kit as an upgrade but didn't need the offset. Realized that after I mounted them. Otherwise never ridden, and it's too expensive to pay for shipping to return them. My loss is your gain. Regular retail price is anywhere from $90 to $125. Get-rid-of-them price - $80 plus ship...

CA DPS V3 resize.jpg I switched to using a Bafang mid-drive so I no longer need this Cycle Analyst. The CA has been upgraded to v3.0 specifically to use the multi-position switch. I'd had it programmed for use with a Mac geared hub motor and the MP switch was configured for levels of pedal assist. ...

Re: Controller placement question

I hadn't actually thought about the effect of waste heat from the controller on the battery. Might be a good idea to keep the controller outside the case then. Even if it didn't get hot when it was outside the case before, being inside without the passive cooling might change that.

Controller placement question

I have a pretty modest setup. 12T Mac geared hub Mac motor on the front of a bakfiets-style cargo bike that I'm building. I have a 52v battery and a 6fet 25amp controller. The whole thing only outputs about 1200 watts or so and I don't really flog it all that much, preferring to maximize my range ov...

Re: The most basic demonstration of why you should consider a recumbent..

I'll just add my .02 cents. I owned a recumbent very briefly about four years ago. I was having a lot of problems with bike fit and getting a saddle that was comfortable for the kind of mileage I was regularly putting in - over 120 miles per week with weekend rides frequently 30-50 miles at a time. ...

Re: Did I kill my battery?

Thanks for the concise answer Amberwolf. Since this is an em3ev battery I'd be inclined to think that the BMS should be decent quality, because they build pretty solid batteries. I'm just betting I wasn't charging it regularly enough and it just went dead too far. The charger that came with the batt...

Did I kill my battery?

I have a 36v battery (Dolphin case from em3ev), that is about three years old. I haven't used it in over a year and a half but I thought I'd been recharging it regularly enough to keep some life in it. I thought I'd just give it a recharge but the charger light is showing green, and while the LED po...

Re: 16T Mac motor splayed fork dropouts - what next?

Thanks for the further, enlightened replies. As an aside - now that I've stewed on this a while, I'm pretty sure that the stock Troll fork was out of spec to begin with. I do recall that the dropout edges were not parallel right out of the box, and had an ever-so-slight splayed appearance. Things *m...

Another thought had occurred to me as well - are those Dr Bass torque arms still available?

This is the actual fork I have that will be going onto my cargo bike. https://www.tartybikes.co.u...

16T Mac motor splayed fork dropouts - what next?

So my 16T Mac motor apparently splayed out the dropouts of the fork on my Surly Troll. I was de-electrifying the Troll and had intended to use the hub motor on a cargo bike I'm building. I found out when I went to mount a dyno hub wheel back in the fork that the dropouts were no longer parallel. I w...

Re: Surging under PAS but not throttle?

Thanks for the input. Everything is set up in such a way that the Cycle Analyst controls everything, so you are correct - the throttle and PAS both are getting their input/output the same way. With a full charge for this morning's ride I'll have to see if it does it again. If not, maybe it was a SoC...

So I noticed something kind of funky today with my MAC geared front hub motor. When pedaling I could hear sort of an oscillation sound coming from the motor, and even looking down I could see the power must've been coming uneven enough that the fork legs were showing a slight fore/aft flexing that s...
