Can you share contact information for Bridger at EBMX - I have the same shuddering problem and also bought my controller from Grit Shift.

That TM frame with very minor modifications could house a huge battery and be made very easy for battery swaps - since TM is a smaller company I wouldn’t it be great if they sold a rolling chassis made for the QS 138 motor.

I’m jealous, would love to ride Glen Helen with other conversion bro’s - this fall I’m making the trip to join you guys.

So do you lower field weakening or raise field weakening to improve range for higher speed.

So lowering field weakening improves range on the street - I thought it was the opposite. I ride more than 50% on the street where more range is typically needed.

I lowered the field weakening setting to 25% on the EBMX X9000 V3 and sensor wires separated from the phase wires - a big improvement but full power starts (hole shots) with good traction still shudder the motor.

Is your 15 mile range just the spare battery or is that combined range using both batteries. I struggle to get 20 miles range with 96volt and 4.6KWh battery.

For your next build you can go with this connector.

Curious why you have two power connectors on each battery, also what is your battery spec.

I had a FarDriver ND961000 controller on the same motor and sensor wires were right next to phase wires. I never had a shuddering problem, I had random cut out problems which were far worse, but never motor shuddering.

I separated the sensor wires from the phase wires like Helienduro mentioned above, it made a big improvement but didn’t totally solve the problem. Lowering the max power setting seems to eliminate the shuddering. So I think i am able to just live with it. Thanks for the set up tip.

I have this index finger trigger throttle for regen set up on my conversion bike with an EBMX X9000 controller. It’s great when street riding to use for braking. I don’t use it off road because it is more like an on / off switch and it’s hard modulate and to use going over whoops or cornering...

I have the same controller and the same studdering problem - it happens in a hole shot situation every time - full acceleration with good traction - if I lower the power level it stops - I will try the sheathing, do it put it on the sensor wires or the phase wires.

I will check out dirt tricks, Amazon / ebay didn’t have smaller ones

Common rear sprockets are 48-51 tooth - smaller rear sprockets are surprisingly uncommon - also changing gearing with front sprocket is much easier.
