    TSDZ2 OSF for all displays, VLCD5-VLCD6-XH18, LCD3, 860C-850C-SW102.

    I’m trying to set odometer to a specific value = 2720 miles. It is stuck on 1689.4 miles. I can set value to zero and that value holds on the display, but if I change to 2720 the display reverts back to 1689.4 everytime. Any ideas appreciated…

    Is there a wiki showing disassembly and parts list for the TSDZ2B with helical gears?

    See post #299. Another ride with air-cooled motor….. I rode 15 miles today on the flat with outside air temp 80F. Average speed was 18 mph. I used highest power level 9 which I have limited to 450 Watts. Cadence was about 90 in slightly lower gear. Scale on graph is off by 2x. Actual max motor...

    An additional note for air-cooling modification. I got caught in a slight rain shower yesterday and thought front wheel would throw water and get the motor wet. It turns out the motor is offset to the left of the frame and not in direct line with the front wheel as evidenced by road worms and...

    I went through all the settings with user manual in-hand. Also reset Odometer to correct value. I did a 18-mile ride and looks like it's behaving. I really like the TSDZ2b with the OSF. Thank you to the team that does the code. A tip of the hat.....

    It seems to be permanently broken. Is there a fix short of reinstalling firmware?

    I have new problem with my TSDZ2 860C OSF version 0.20.1c-4 and TSDZ2 OSF version 0.21.4. I have 1790 miles and the odometer keeps forgetting the last ride. By that I mean… I ride 10 miles and odometer increases 10 miles, but next time I ride it starts at previous odometer and doesn’t remember...

    This should be my last update for air-cooling the TSDZ2b motor. I added three more large cooling holes in the cover so it looks like Swiss Cheese. I just rode at power level 9 (making 450W) on level road at +20 mph for 7 miles and only saw 140F briefly. I was peddling hard... Outside air...

    Next logical step…. I figured as long as I have one cutout for inlet air that is covered by a filter foam, I might as well make more openings to improve airflow. So, I did…. I bought Frost King Air Conditioner Filters, 15 in. x24 in. x3/16 in. Open Cell Foam on Amazon for $2.39. Only drawback...

    I’ve even been thinking about liquid cooling the motor. I know….crazy idea. I wonder if the motor is sealed? Looks like it might be… The speed controller / CPU is potted, so it should be sealed. The three electrical cables that feed out the ring gear side would need to be sealed well with...

    See my post #291 above... So, here we are end of June and temps in mid-80’s with high humidity. Today I rode TSDZ2B OSF with my air-cooling modification and I like it a lot. I was using full power (I have limit at 450W) and rode level ground for 10 miles with stabilized motor temp of 138F. Speed...

    I don't know about V2 controller, but I will advise to buy the "B" model with helical gears instead of spur gears. Good design improvement....

    I have TSDZ2B running OSF 860C ver. 0.20.1c-4. I am having problem with indiscriminate Trip Distance and Trip Time resetting during a ride. Doesn’t happen every ride, but maybe one time out of four. I have trip memories (A&B) to reset at one hour and that works fine. Problem is when I ride…...

    I have TSDZ2B running OSF 860C ver. 0.20.1c-4. I added motor temp sensing and set units in Fahrenheit. Temp sensing works great and appears very accurate. I have problem with graph of motor temp showing 2x actual value. See photo below where motor temp is 134F and graph shows approx 270F. Is...

    My TSDZ2 (ver. 1) started to make noise. I greased and it didn't help. Also replaced blue gear with same result. I bought a TSDZ2B from AliExpress for $291 shipped. This has latest helical gears and is nice and quiet. I had to swap out the OSF speed controller from the original center-drive...

    I don't intend to let that happen. I only ride if weather forecast is dry. I suppose I could take a plastic bag in my tool kit and use some tape to cover the filter in emergency....

    I did a 7-mile ride today to further test the air-cooling mod for the motor. Outside air temp today is +58F compared to -30F windchill last weekend with Bomb Cyclone... I have power limited to 450W and 12A. I again used max power level (9) and one or two gears higher than normal to task the...

    I’ve been thinking about how to clean up the air-scoop for my motor housing. I have a temporary plastic funnel for testing. The front end of the Mini Shark battery has the right shape to scoop air from up-high on the bike frame in a nicely protected spot. I’m thinking of cutting a window in...

    I think removing cover would be a very good test. I will add to my list for next summer evaluation. My overall goal is to keep motor in safe temperature range for the normal routes that I ride which are mostly flat but include 200’ elevation change halfway thru the ride. My riding speed is ~...

    I just did a 3 mile test ride in the “hood”. Too cold to ride normal trail. Outside air temp is 43F. I used max assist power level and kept bike in higher gears to increase motor temperature. Display graph shows 450 watts for most of the ride. Motor reached a maximum temp of 145F. The...

    I’ll be able to measure inlet air temp very accurately, and I think get a good handle on exhaust air temp as well. What I won’t be able to do is detect or measure air flow. Any air flow at all through the motor housing is better for cooling than a closed system. If I measure a difference...
