DM02 ~ the 98% Project ~ ToSeven DM01 & DM02 Series T24 Display Tutorial

A basic tutorial to help new DM0# series motor owners navigate the T24 Display.
There's lots of options, most are best left well alone.
Recommended is setting the Wheel Diameter, Battery Voltage, Max Amps for the Modes, how to set the Speed and Percentage of Power for each Level and how to Save the Changes.
What I don't show, but is worth noting, the FACTORY DEFAULT option at the bottom of the first Settings Menu.

Hi Ian, thanks for posting this, my DM02 is arriving tomorrow. Your videos are going to be very helpful.

[@ianbourne4084]

You're welcom Ken. There's an active community of DM0# users on discord, a web chat forum type space. Feel free to ask my any questions and I'll help where I can.

How does this compare to the tdsz2

[@ianbourne4084]

No comparison now... Hands down better. Until the recent firmware updates, the OSF TSDZ2 was a superior riding experience until you went over 5% but now the torque sensing has been tweaked, possibly with the help of Stancoke, the DM02 is better all round. .. more power, better efficiency (doesn't lose as much power through heat), pretty good ride feel, superior cooling and competitive price. It is the motor I wanted my TSDZ2 to be

@@ianbourne4084 Wow, where is the best place to buy it in the UK. Also what battery suits it best, I'm guessing 52v 20amps?

[@ianbourne4084]

@@Lecia-lithium They're designed for 48v and 48v works fine. The quallity of the the cells and the BMS is as important as the voltage and ah. My size consideration is range for weight. and I'm happy with 48v 15ah, so much so that I'm getting a couple of batteries built that size, one with Samsung cells and the other with LG cells, so I can give a 'commuter's opinion'. With my cheap chinese cell batteries bought with hub drive kits years ago I was able to get about 70kms... I rarely commute that far. Currently, the best option to buy in the UK is the ToSeven store on Ali Express. this is the factory distribrution outlet and not a cowboy outfit.

What is the maximum amps you can use in Sport mode? To7 don't seem to mention this anywhere. Does the display prevent you from setting it too high?

[@ianbourne4084]

It really depends on voltage. I've had mine running ok at 18 amps on 48 volts though To7 recommend that 18 amps is really for 36v and 15 amps for 48 volts. That said, if you get a DM02 the controllers tend to be set at 36v and 18amps as a default for ALL modes - Eco/City/Sport are all the same - so lots of new users have just changed the voltage to match their batteries and not bothered or didn't know how to adjust the amps in the modes etc. I've currently set mine, to run with 48v and 16amps max and with a full 54v in the battery I will get over 800w of assistance for a while until the voltage drops. However, I rarely use the highest settings available. I'm currently running an experiment where I've increased the levels from 5 to 8 and I just stay in one mode, Sport, but then really lowered the power and e-assist levels on the lowest settings so that for general flatland riding at a steady 75 to 80 cadence I'm only drawing 100 to 200 watts. Naturally I've increased the subsequent settings so that the steady cadence and load wattages goes up and by some flook it seems to multiply the levels X 100. - so level 4 will provide around 400w and level 5 will provide around 500w etc. I always set the highest level of any parameter to either 100% or the max I want as the highest of any parameter seems to be the default that all lower numbers become a percentage of... hope that makes sense. ONE essential bit of info is, TEMPERATURE. The motor seems to be very robust but the controllers don't fit very snugly in the housing so there's quite an 'insulating air-gap' around them so they are prone to over-heating. So if you go crazy drawing big amps, the controller will over heat and start to drop the wattage until it cools down.

@@ianbourne4084 Thanks, mate. Do you have more details on the power and e-assist levels you're using? They sound pretty good.

[@ianbourne4084]

@@darrenstribning I'll have a crack at making another video but in the interim, are you on any of the To7 chat sites? discord or what's app? I can send photos of the current settings for power and e-assist

@@ianbourne4084 I thought I replied but it seems to have vanished. Yes, I'm on Discord on the To7 groups. Cheers!
