    2 Chainrings on TSDZ2B - is an adapter necessary?

    Thanks for the input on the chainrings folks. Over on the recumbent forum I frequent I know several of those folks have tried double chainrings and the derailleur approach generally means flat-mount with some spacers which works well enough. So far I have a week of use and with the stock 42T...

    2 Chainrings on TSDZ2B - is an adapter necessary?

    If you want to run two chainrings on a TSDZ2B will both rings install onto the existing spider that is part of the motor or does one need to purchase an adapter? I've seen some adapters for both 130BCD and 104BCD but it's unclear if these adapters will allow installation of two chainrings or...

    Is there much market for a used BBSHD with very large 52v EM3EV triangle pack?

    I have not. I bought a TSDZ2B with OSF loaded that I'll be installing on my new TerraTrike All Terrain. For now I'm keeping the BBSHD and will also be keeping the big EM3ev triangle pack battery. The BBSHD will get swapped over to my wife's Trident Spike trike (same make/model of trike I've been...

    BBS02 vs BBSHD - how much can you alter programming also

    So I already have the BBSHD and I know of it's advantages in heat dissipation and torque over the BBS02, however I'm looking for a lighter weight motor. Since I can't afford a Cyc motor (or at least not in the budget right now), I had been looking at TSDZ2B for a lighter motor with bonus torque...

    Any suppliers selling TSDZ2B that will work with 52v battery?

    I want to put a TSDZ2B on my TerraTrike All Terrain recumbent trike and was wondering if anyone knew if the this current iteration has a display and stock firmware that will recognize full voltage on a 52v battery? Or, would I need to flash the open source firmware onto a TSDZ2B stock motor? I...

    Is there much market for a used BBSHD with very large 52v EM3EV triangle pack?

    Just that quick question basically. I'm contemplating getting the TSDZ2B to use with my new smaller EM3EV Super Shark 52v battery - mainly for torque sensing, lower wattage, and lower gross weight of motor. I'm using the BBSHD on a tadpole trike now and it's really kind of overkill. Originally...

    Question about watt hours display on DPC18 for BBSHD

    Thanks Amberwolf. I must've read that passage at least a couple times but it didn't register that the setting was amps or watts. I think watts is probably a more useful setting. I don't still have that Cycle Analyst, unfortunately. However, I had been planning on getting another one and...

    Question about watt hours display on DPC18 for BBSHD

    Okay, so I have a "48v" BBSHD that I purchased a few years ago from EM3EV with a 52v triangle pack. The pack is 17Ah and it was charged to 90% before I took it out for the first test ride, which is when I snapped the photos I've attached. On the display I guess I have it configured to show the...

    BBSHD and Rohloff - shift sensor?

    I've had a couple rides now on the electrified trike, and have found that just the usual pause before shifting is adequate enough, however I find that I must wait a half second longer for the chainring to stop spinning, since unlike pedaling without the mid-drive, *with* the mid-drive the...

    Is there a company that can rebuild a battery into a new configuration?

    Amberwolf - When I first got the battery I almost always charged it to 100 percent to get the maximum range available and even though I knew that charging to 80 or 90 percent would give longer life via more recharge cycles. I justified that with logic that even though I was charging to 100...

    Is there a company that can rebuild a battery into a new configuration?

    The thing that makes me wonder is what the performance of this battery is going to be once I start using it again. It's effectively been at an 80-90 percent storage charge for nearly two years now. When I fired up my BBSHD a few times recently as I'm installing it on this new trike, plugging in...

    Is there a company that can rebuild a battery into a new configuration?

    I want to say the pack is something like 18 Ah? That's what I remember. The more I thought about, the more it just seems like making it work as-is, is currently the best option. Use it until it's used-up and buy a new pack. It's just going to be a LOT more hassle trying to devise and fabricate a...

    Is there a company that can rebuild a battery into a new configuration?

    Specifically what I have is a an EM3EV triangle pack that I purchased back in probably mid-2016 if I had to guess. It actually doesn't have a lot of use on it despite being that old. In fact, the 2 1/2 years it's not been in use at all and all I have done is regularly put a charger on it at the...

    BBSHD and Rohloff - shift sensor?

    So, I've got a BBSHD and in the past I've used it on a cargo bike along with an Alfine 8 speed hub, and NO shift sensor. I learned early on with Alfine hubs that you pause when shifting and I found that the momentary pause before shifting was enough to cut off the BBSHD anyway, so no shift...

    Question about Bafang BBSHD maintenance/parts

    I was able to get a full set of gaskets for my BBSHD (both paper and rubber), as well as some other parts from California EBike. I did have to buy a second nylon gear (didn't actually need it but swapped it out anyway), from a seller off Amazon. The only thing I've had trouble finding was a...

    BBSHD - has always seemed to have high resistance when un-powered - Suggestions?

    Amberwolf - that's pretty much how I thought the geared hub clutch type system worked. However, in the BBSHD, it's clear that all of the various gears are enmeshed all the time which means when the motor is unpowered you're essentially turning all those gears against the inherent resistance of...

    BBSHD - has always seemed to have high resistance when un-powered - Suggestions?

    Update: I ordered spares of gaskets, thrust bearing, an extra clutch and nylon gear, just in case there was anything funky inside my motor. TL;DR - nothing wrong. A little bit of black grease seemed to have leaked through onto the nylon gear but only a tiny amount. I cleaned everything and...

    BBSHD - has always seemed to have high resistance when un-powered - Suggestions?

    For an update - I went ahead and ordered a full set of gaskets for the various parts of the motor shell, also ordered thrust bearings (just in case - mine have side-to-side play but I don't think it's quite enough to warrant replacement), and ordered the freewheel clutch part - the one that...

    BBSHD - has always seemed to have high resistance when un-powered - Suggestions?

    Never had any dragging brakes or issues with wheel bearings. This BBSHD has always felt like there was excessive resistance when attempting to pedal it un-powered. Shifting to the lowest gear should have theoretically made it easy to pedal, but instead it always felt like a pretty noticeable...

    BBSHD - has always seemed to have high resistance when un-powered - Suggestions?

    So I have a BBSHD and for a while I ran it paired to an Alfine 8 internally geared hub. On a few occasions when I managed to run my battery down to the low voltage cut-off I found the bike to be very difficult to pedal, even in the lowest gearing combination that I had. It was like I was...

    SOLD!! NOS NuVinic N171 with everything to rebuild $150 SOLD!!

    Sorry to bump but I want this gone. Now looking to ship anywhere CONUS for $150 with all the extras included. If you want a geared hub that will laugh at the torque you dump into it, this is the hub. The only other thing close to being this strong is a Rohloff.

    SOLD!! NOS NuVinic N171 with everything to rebuild $150 SOLD!!

    Bumping this from my listing from last year. Still have this hub and would consider shipping it anywhere in CONUS for the asking price. It's a heavy hub, so I'm eating the shipping and whoever buys it is getting a better deal, especially with the rebuild parts included.

    Looking to trade my welding rig for a recumbent trike

    SOLD!! NOS NuVinic N171 with everything to rebuild $150 SOLD!!

    SOLD I'm taking a loss on what I spent, but this is new, never-ridden NuVinci N171 hub (purchased for over $100), from an ebay seller, along with a new shifter, all small parts for replacing shift box, shift rod, cog, and even a bottle of the non-Newtonian fluid for whenever you'd need to do a...

    Which geared hub for BBSHD in a full-fat tandem trike?

    Turns out I ended up buying a Rohloff after all. I was having problems with the shifter itself not wanting to effectively pull both cables equally. I'm betting NuVinci never expected someone to use their hub on a recumbent tandem and for it to have to pull cables that were nearly 4 meters long...
