Is it cheaper to go through them? and I guess the rear wheel needs to be different?

What model SRAM do they use?

My HD750 bikes came with the SRAM X-5 9 Speed cassette. Had a bad derailleur (b-screw mount broken) upon shipping.
Sent a few pictures and they had a new one to my front door in about 1 week. My bikes are hub drive Bafang 750, not middrive.
The SRAM X5 is perfect so far... smooth shift and pretty quiet once tuned.
I've had a another vendor contact me a while back about buying some of their MD1000 bikes setup with the 9speed cassette setup. Here's some pictures of they sent me.

This is Really disheartening fellas. My md1000 is clunking at random already too. I suppose I'll pull it apart and see what I'm dealing with. I'm a mechanical person but completely unfamiliar with the design and workings of the SA IGH. In short, this blows. I'm almost scared to ride it now

How much belt tension are you running?This is Really disheartening fellas. My md1000 is clunking at random already too. I suppose I'll pull it apart and see what I'm dealing with.

The parts list was in a previous post (you're welcome
). The SRAM drivetrain arrived today. Fast shipping, nicely packaged new wheel with 9 speed cassette installed, SRAM derailleur, SRAM shifter w cable, new chain, thru axel, chainring and the hangers for the derailleur. Basically, everything needed to convert the IGH belt drive to a 9 speed cassette/chain setup. I messaged Kyle at Bolton about the issues with the SA IGH and he said he had spoken to his contacts and he believes "Bikonit will change to a different hub moving forward". I received no other details so please don't ask. I have no idea if that is also the Leili plan with their version of the MD 1000 dual battery IGH Belt drive bike.
On a side note, I finished some meetings early and decided to get out on the empty bike trail and try and set a new Strava ebike speed record for a 10 mile segment of the 22 mile ride. My average speed for the segment was 26.5 mph and overall is was 21.9 including some time at a stoplight on a 6 lane road that bisects the trail. What was notable about this speed run is that I was in 5th gear, level 5 assist most of the way and had zero mis-shifts or odd noises from the IGH. The "secret" was to at all times, have a light touch on the pedals when engaging the motor and or shifting. It slowed me down a bit and it's not an acceptable solution to the problems with the IGH but it was an interesting test.

The rear tire aligned too?
All of the concerns/complaints with the IGH have been the 5 speed model of the SA. Does anyone know if the SA3 has similar issues with 750+ motors? Thanks

Wattwagons uses the three speed
Indeed.

I could never get the frequency reader to be accurate. Maybe something is broken.
They were offering it but now it is no longer listed on their site as an option for their bike.

I just looked, I still see it as an option for the crosstour
Sorry, I was referring to the two new ones, Hydra and Helios.

I was told by Leili that they are testing a new hub drive but due to the current issues, they will be taking more time testing a new one. It may be awhile before we see a replacement and there is no comment regarding an upgrade path for existing MD 1000 owners. They also said the Bikonit brands are the American version of their MD 1000, MD 750 and HD 750 ebikes so they are the same bike.
I have a new name for the Sturmey Archer RX-RK 5 ... it's the granny tranny.

Leili finally promised to put me chain drive accessories to come. Without a rim. Need to replace hub SA instead.

I already bought another rim with a threaded gear mounting. I was thinking of tuning in a direct strap drive to that rim. So I do a single gear.
Pedaling the cadence with maybe 90-100 motors max. 150
