Torque sensor driving me crazy

[POregon]

I've had my Mokwheel Basalt for a little over a year now. Haven't ridden it much. I assume the torque sensor is the culprit for causing the motor to surge with a burst of power constantly. I ride with my wife on trails with little to no grade mostly at 9-11 mph. At this speed it's most noticeable and feels like you're getting a little push every time you make one or two revolutions of the pedals. When you stop pedaling even intermittently, it's as though the torque sensor doesn't pick up on when you resume pedaling and take 3-4 revolutions for the motor to begin providing assistance. I did contact Mokwheel customer service - they had me make an adjustment in the internal settings, but this has not resolved the problem. Has anyone else experienced this issue? I'm wondering if I have a defective bike......

PS - I also own a Ride 1 Up commuter bike that has a torque sensor and it's a joy to ride and is smooth as silk with this feature.....

Yeah that sounds like a faulty or old and faulty torque sensor, but i could be wrong.

Let's see wut others say

Hi, so someone on the EBR forums has a Basalt and those from an earlier generation had a cadence sensor in them and not a torque sensor and it seems it is a bit unclear when they started shipping which type. The fellow on EBR was not sent the proper one. On top of that, it appears their cadence sensor is speed based not wattage based, which can be even more stop and go, regarding when it initiates or cuts out. If you give Mokwheel your bikes serial number maybe they can confirm which type of sensor you actually have and then we can try and figure it out.

Than you for your input, I’ll follow up with Mokwheel on that……

I had exactly the same problem on my Electric Bike Company R model I received on 8/19/24. I had ordered it with the torque sensor option, terrible to ride, pulsing, jerky ride. I took it back to EBC and had them take the torque sensor off and it is so much better now.

I have just purchased the Basalt and I had the same experience. I did some digging and if you go into the settings, you can find a setting called "Intensity" which basically is how much power is applied when the motor kicks in (1 through 5). By default is it set to 5. If you lower it, then the power added is not so abrupt. I think this limits the amperage applied to the motor. I have mine set to 2 and that feels less like you are going back and forth from no throttle to full throttle. While it is still far from great, it's much better. There is a speed limiter setting too which I thought would help with runaway power, but it only works for the throttle. So even with the Intensity set to a low number and you are on PAS 1, if you want to only go say 8 mph, you are basically feathering the pedals to keep it at 8 mph. If you press on the pedals with even the lightest force, the bike will just accelerate right up to about 19 mph. Some will say that it has a cadence sensor but it will go slower but you have to press really lightly on the pedals. Where my wife's cadence sensor bike if you do that, it will either go right up to 8 mph (PAS 1), 14 mph (PAS 2), or 19 mph (PAS 3) no matter how slow you pedal the bike, all you have to do on hers is keep your feet going around in a circle...even 1 rotation per minute will make the motor kick in.
