Many thanks gwl3. Sounds like you'll have yourself a nicely sorted little bike there...

Thanks gwhy. The bike was like this out of the box, so I'll be looking for a repair under warranty - I just needed confirmation that it is indeed faulty, and not just an intrinsic characteristic. D.

Hi. My 5 y/o son has an Oset 16.0 racing and loves spending every spare minute on it. The "throttle" has always troubled me though, and having had no previous experience with e-bikes of any description and no ability to benchmark against other bikes, I need the help of forum members to ascertain whether the characteristics of his bike are normal or not.. From a stand-still all the way to full power the "throttle" behaves as expected and can be modulated well with a corresponding increase in speed at the rear wheel, HOWEVER when winding off the "throttle" from any position the speed/power cannot be modulated other than to eventually fully stop the transmission of power to the rear wheel at the point when the "throttle" is fully "closed". To put it another way the power is variable on application, but remains at the previously applied peak until the throttle is fully closed - there is no variability on the way back down - just stop. My son knows nothing else and has adapted his riding style amazingly well to suit, but the scenario outlined above surely cannot be correct can it? I would assume that the speed/power should be variable regardless of whether one is applying power or backing off. If someone could offer me the benefit of their experience it will enable me to ascertain whether I should be seeking a repair, or a modification. Thanks.
