May 15, 20187 yr I don't think the gyro can predict when you need a little more power to lift the front wheel over an obstacle in quite the same way that a torque sensor is going to respond to your input. that's when the inclinometer comes in handy. Both are built into the same chip.
May 15, 20187 yr I'm talking about a pre-emptive increase, once you hit the obstacle maybe a branch on the trail it is to late to increase the torque because you are already over the bars! When I am riding off road particularly when it gets steep and narrow you need to be able to control what is going to happen, not what has already happened. I'm not saying the other systems won't work for some but for me and some others on here they are not the answer.

I'm not saying the other systems won't work for some but for me and some others on here they are not the answer. you do have a point. The gyro system won't suit everyone's requirements but on this, all systems have their critics. That's why earlier in this thread, I suggested that the torque sensor system should also have switchable a throttle. The old BH Neo and Evo bikes had this implementation. The gyro is the way of the future because it has less wiring and intrinsically cheaper to implement.
May 16, 20187 yr VictoryV, you make me feel so old! don't get me started on running a world wide communications hub for international military communications at 50 bits per second. It would take nearly 1 second to send the word Victor! - 1970
May 16, 20187 yr On the original question from the OP. On my ebike that I use for commuting I have a cadence sensor. I much prefer this, for commuting, as I want full power with minimal effort. Effectively I want an electric scooter - it just happens to be bike shaped and has pedals. My e-MTB on the other hand is a Haibike with Yamaha motor. I prefer this for off road use and for leisure use when I want to get some exercise. For me the cadence sensor vs torque sensor question really depends on the individual use case and personal preference.
May 16, 20187 yr Yesterday I saw my first ever throttle in use on a pedelec! A young lad walking his dog (not on leash, on the footpath... ) in San Sebastian. No effort to move the pedals whatsoever just your average electric scooter. A 285€ combined fine just waiting for a policeman to happen!
May 21, 20187 yr I learned something new today. A potential supplier mentioned their 'Inertial cruise system'. Above a set speed, if the user stops pedaling, the bike will maintain its current speed until the user decides to brake or start pedaling again. What do you think of it?
May 21, 20187 yr To be compliant with EN 15194, the power has to stop when you stop pedalling. I've used cruise control on some bikes, but I never really felt comfortable with it. I guess you'd get used to it, but I always found it a bit disconcerting when it engaged when I didn't want it. On the surface and without trying it, I'd say it's one of those ideas that sounds good in theory, but has little practical use other than to save you the cost of a throttle, and only then if there were an on/off button to switch it off when you didn't want it active.
