I've been riding a TSDZ2 with OSF firmware for 4000 miles. This summer, I installed a Toseven DM02 on a similar bike, both older steel Raleigh 10 speeds. The DM02 is the red one.
I've been really happy with the TSDZ2/OSF. Could not ride the original TSDZ2. Not enough assist for an old guy. Much better with the OSF. After three years, I reloaded the original firmware to se if my opinions changed, No, it's still too weak for someone who has been riding 20A KT controllers on hubmotors. ,The DM02 comes out of the box with about the same power as my TSDZ2/OSF in level one, and is stronger when pedalled harder, . That's my subjective analysis. Quite happy with the DM02,
If you prefer numbers, the DM02 shows the wattage. It shows about 100W with light pedalling in its first assist level. Goes up to 400W with heavier pedalling, In the highest level, I believe 500W is there. It maxes out around 12 amps, so it's not going to go much higher. I think it's a good candidate for a light weight pedelec style bike. Still only half the power of a BBS02, so if you want that kind of boost, look at a DM01,
