I am a doordasher I own two uart bbs02 both have over three thousand miles on them. Controllers are there weak point. You can get BBS02 under $500. I run in all weather conditions. Here what I learned keep the rpm high in high gear. Which means never have bbs02 in a gear that it can not achieve top motor rpm. It will go for ever. Keep you chain clean, lube and adjusted.
You don't have an impact gun? That should have worked w/o resorting to a vise grip.
You got a TSDZ2B, not TSDZ2, which is NLA? Looking forward to see how it works out on your recumbent.

I know its a 2b, I got one three years ago which was a 2b. Just didnt feel like typing a b.
The whole thing was spinning including the round nut with the slot. An impactor wouldnt do anything except make it spin faster. Sheesh..

I run a mild mod with the OSF on my e-bikes to improve rideability, with the TSDZ2(B)s I have covered thousands of miles, my "main" mullet e-bike has a TSDZ2 drive with the axle third bearing mod and a mild tune up has covered well over 3000 miles, my latest is a 29er with TSDZ2B which again with the mild tuning mod and the axle mod. Is the vibration coming from your TSDZ2B drive? I have had this problem, the vibration was coming thro' the frame from the back wheel, the spokes had stretched, so I just rebuilt the back wheel with Sapim Strong spokes, did a mid-drive change to find that out, but did have a spare drive.

Pretty good price. $244 before taxes with free shipping for a TSDZ2B with EKD01, I bought a spare prior to the tariffs for $265 and prices have dropped. We have 4400 OSF miles each on a TSDZ2 and TSDZ2B with no issues that couldn't be addressed with some re-lubrication.
I learned that the odometer resets to 0 at either 9999 km or 4100 miles. I like the torque sensing, but I still want my bikes to give me 100 watts in level 1 with easy pedaling, like a hub motor, so I use the OSF.

The motor that is on the trike (tsdz2b) developed a vibration after it was carried in a bike rack on a camping trip. I added the extra bearings but that didnt do anything to improve the issue. It only seems to happen when there is a heavy torque load, otherwise it runs normally. This particular motor has about 1600 miles on it. I'm not sure what I could do other than to tear it apart and look for something cracked or broken. When I added the bearings I noticed that they were fairly loose on the shaft, can't say that level of engineering impresses me, but hey, I bought another one.
On the new motor/project I managed to get it connected enough to take it around the block a few times. I still need to work on the battery mount and clean up the cabling, but I got it out. I also need an extension cable for the speed sensor but its mounted. All I can say is that it is quite the little rocket ship. At about 60 rpm on the cranks it was doing around 18mph, not bad for a mid drive on 20" wheels. I should be able to button it up tomorrow and go for a better test ride.

Its a Sun EZ Rider AX. Aluminum frame, 20" wheels, fairly high end components for what it was. Weight is about 35 before any mods. They made a steel framed version, that was about 40. There is also a larger version, it has a 26" rear and 20" front and is longer. I also have one of those sitting in the shed. I had a motor on it but took it off to put on the delta trike.

Check out this build by a user here, SteelRazor. Twin motors too.

With that setup I would be using a 60 t chainring and would have a direct drive hub back there.
I love the TSDZ2 on my 42 lb Raleigh hardtail (currently 3286 miles), running great. It could break anytime knowing this motor. Two nights ago I bought as a replacement just in case:
Varstrom EKD01, TSDZ2B 48V500W 42T, Brake Sensor, from Greenergy Choice Store on Aliexpress $286 shipped.
It's now with Fedx, estimated arrival Nov 27
Hope Greenergy is reputable. Anyone bought from them?

Interesting that it has a rear suspension, no front. How does it ride and handle over pot holes and rough terrain?

So I think this bike project is close to completion. Yesterday I pulled off the aluminum angle mount for the battery and painted it black and centered the base for the battery case to bring it more inline.
I also removed the cheap plastic rear fender I got for it and reused an old metal Sun fender I had on hand from the Greenspeed. The biggest problem with the old fender was that it was mounted to the swing arm and there was just too much motion when riding and it jammed the fender into the tire. And holding it on with cable ties just didnt cut it.
So on this fender I mounted a couple of stainless cable clamps and made a U out of some stainless corner braces. I secured the cable clamps with some hose clamps with some heat shrink to keep it from doing too much damage to the paint. Same with the rear U, I used a hose clamp with heat shrink. On a couple of short runs it seems to be working fine, no evidence of the tire hitting it and it is very solid.
On the first couple of test rides, I noticed the motor display was a bit more optomistic than the bike GPS. I had set the wheel diameter to 20. I went back in and set it down to 19 and it was better but still high, 18 seems to be the sweet spot, within a half MPH give or take. I still need to mount an extension for the speed sensor and put a better kickstand on it, but I'm very pleased with how it turned out. It can cruise easily at 15 and seems to max out at around 18. If I fitted a larger chainring up front than I could get a bit more speed out of it, but I think I'll just run it like it is. Handling is very nice, much more nimble than a typical LWB recumbent and the cushy tire in the rear with suspension makes for a smooth ride.
Total cost for the project is about 560 give or take. 250 for the bike, 250 for the motor, about 50 in parts and materials. I have two identical batteries that can be used on 4 bikes since they all use the same mount. Recumbents these days are incredibally cheap considering how expensive they were when new. I guess it's a bit of an aquired taste, but at this stage I would be hard pressed to want to ride anything else.

I'm going to say TSDZ8. It's under $400 and spins fairly fast and has better torque and a better rotor than BBS02.
The chainring adapter is $60, though, and then sprockets and bolts, or there are "Gustavos" for them with the offset for around $70.
(steep, I know)
I've been using adapters and shimming everything over for the best that can be gotten with what's there.
Bah, this build's a done deal, I'm late!
