  1. Hello! do you know if the shaft is a standard one, or a tonaro exclusive part?
    Mine just broke (it snap right off flush to the gearbox) after over 15 000km of loyal service.

  2. i BELIEVE LATER MODELS DO NOT HAVE A CASTELATED NUT BUT A SNAP RING

  3. Could you please let me know the answer for the following question: is the reduction gear (as shown at 5:23 timing of this video) made of plastic / nylon, or is it made of steel ? Are there moving parts made of plastic inside of this motor / gearbox ?

  4. Do you now were i can buy the axis?

  5. Hello Hyper, what an amazing job!. I dont know exactly what the problem is on my bike, since i got it almost for free cause it needed to be repaired. When i put on the throttle, I hear the motor revs – slow – but it doesn’t make the system spin, and i dont feel any push when i am spinning with my hands. I may say that i got it also with broken wires going to the control, so i am not sure what to expect (i just did a test connecting them manually). What is the name of the tool used at 0:20 ? Congratulations and thanks again for sharing. Cordially, Sergio

  6. I’m here because I spelled tornado wrong

  7. question – is this what I need to do when my motor still revs but the tires dont spin? thanks

  8. Hello and congratulations for this video. I just bought a used mountain bike Tornaro. But I see that the front plate is only 34 teeth on my bike. I see that yours is 52 teeth. Where did you find it? Thank you very much. Sorry but I do not know anything at all. Cordially. Bernard

  9. Thank you for the upload – seeing it done made a minor repair for me so very much easier. AAAAAA+++++++

  11. Is the gearbox output shaft supposed to turn counter clockwise with the motor off? My Tonaro gearbox started to make a grinding sound and now the bike cannot be moved backwards because the front cog won’t rotate backwards. I was about to replace the one-way bearing and freewheel bearing but I think my gearbox is the source of the problem. Any advice?

  12. Hello Hyper I only just found your video and it’s very informative, even without audio.
    My hypothetical question is, if I need to replace the electric motor, mine is a little noisy and 200W, with a 250W is it an easy change over or even possible. Tia.
    PS do you have a schematic of the whole motor/gearbox assembly that you could post. Cheers
