I guess this all depends on How durable your Noggin is ! ? I'm pretty reckless my self, and admit I tend to ignore my helmet which Hangs on the door ... Definitely no excuse for it though. I'm glad you're ok ! ?
Sorry they stuck it to ya ! Food for thought for the Rest of us tho, right ! On a lighter note, Did you know that Fed Ex and UPS are going to Combine companies ?? ... They're going to be called FED UPS !!! ???
It sounds like it has a Cadence Sensor, rather than a Torque Sensor. These determine when Rpm's are applied to your Crank, or the amount of Force applied to your crank or Pedals. Cheaper Ebikes tend to have only Cadence sensors and Some have only 6 Magnets while more responsive models have 12...
