Opening up the DM02 and TSDZ2 mid-drives
After I rode 400+kms with the DM02 on the trike, I re-installed the TSDZ2 for 75kms before confirming that I would install the DM02 permanently. Sept. 2023 Took time to open up both mid drives before finally installing the DM02 on the Trike. I now have 1200kms on the DM02

Nicely done, great comparison video!

For the speed sensor: place some thick rubber (cut from say a handle bar clamp seal/rubber) under the sensor mount where it attached to the frame and push it closer to your wheel. I used a piece of rubber that had ridges along its perimeter (for the handle bar clamp to sit within) that worked perfectly. It was ~3/8" thick.

👍I have used that solution on other bike builds, Stacking two magnets on the spoke, was a simpler and faster for me and has worked for 3000+km

Thanks, interesting vid. Yes, I had that nut jam on my DM01 (at 6:30) ... it wasn't easy to get it unstuck!

Its nice to know that a dual chain ring works with the toseven. I have the tsdz2b on my recumbent and will put your motor on a recumbent tandem.thankyou for a real nice video

I installed a Sturmey Archer 8 speed IGH with a 42T 48T chainring. Video is in the work with spring upgrades.

I have both motors as well. I haven’t installed the DM02 yet. I’ve had the original Tongsheng for years and use it every workday (even in the cold winters). I’ve never had a problem with it.

The DM02 runs a lot cooler, I had to replace the torque sensor coil on the TSDZ2 after 3000km, I have 500kms on it stock TSDZ2 and 3700kms with the OSF installed, over 4000km total. The DM02 firmware needs some work, but mechanically I think it is better engineered then the TSDZ2

@wdj935 5 месяцев назад

@@hisforhack thanks for your reply. This is good to know. I do have a slight problem with the TSDZ2. Sometimes it will hesitate for a few seconds before assisting me when going up a hill. It started doing this a few months ago. Im

I had sold & installed the original TSDZ2's for about 5 or more years with very few problems. When the B version came out we had several complaints about how under powered it was. Then we started seeing lots of posts about problems with the various OSF mods people were doing so we stopped selling them. I am curious to know if overall the Toseven in 500 watt /48 volt is improved enough to consider carrying them.

I was looking at getting the toseven but went for the CYC photon instead

@ericfleetwood6744 2 дня назад

What was your experience with the Photon. Is it on a trike? TIA

@manickbarry День назад

@@ericfleetwood6744 no I used it on a Scott sub sport 30. It’s a great kit and the most difficult part of the install was protecting the cables/hose under the bottom bracket from being trapped by the motor.

I'm really curious about the fit of the bearings. I have 2 tsdz2 running at 11amps i think. So 370 watts about. One had water ingress imediately (replaced the controller)now crazy noisy due to corrosion inside. The other had bad creaking bb (still has 2000km later). Is the toseven more serious on the fit of bearings and waterproofing?

@hisforhack 2 месяца назад

My DM02 was a little noisy for the first couple 100km after it was broken in it quieted down. There is a moulded rubber seal around the wires, and in general has better weather proofing. No mid-drive is waterproof.

It looks like you have plenty of clearance there on your BB... I'm looking at using one of these for my wife's bike, but it's a 46mm/pf30 setup (I'd use a fsa-bsa solid fsa adapter). I think a bsa is 34mm ID.. Do you think there's at least 6mm clearance between your bb and the motor housing? That'd be about the difference I'm looking at on the radius for clearance.. Thank you for any insight!

@hisforhack 5 месяцев назад

I believe you with need a offset adapter, Google "Eccentric Bottom Bracket Adapters BB Adaptors" you should find more info.
