I need all that power maybe 5-10% of my commute time to be able to keep up with 35 mph traffic. And maybe 70% of that power to keep up with 25 mph traffic about 15-20% of my commute time. I commute on my bicycle almost daily.

No. I'm running mid drive Bafang Ultra with 3000W 240Nm controller (the motor) paired with Kindernay VII gear hub (the gearing system). Bafang Ultra (the motor) connected with the gear hub (gearing system) with the chain. And all that 3000W power with 240Nm torque plus my legs push force go thru...

I use 44T standard Bafang steel chainring (the biggest the frame allows) and 14T Shimano steel 3/32" cog. I could use bigger cog but that would increase the stress on the gear hub I would like to avoid because of the gear hub is the most expensive part of the drivetrain.

I found that my Bafang starts destroying the chain before it is even stretched up to the 0.5 wear mark. What basically happens is it has so much torque it crushes the rollers of the chain. The chain is still fine according to the chain checker, but the rollers look deformed (squished) after just...

I think if you deal with high torque mid drive motors like Bafang Innotrace X1 the only option is to use heavy duty single speed chain with gear hub. KMC eCargo1 EPT also cached my attention. They claim it has "diamond durability" rating and 50% higher tensile strength comparing with industry...

Has anyone tried single speed Izumi Chain V Super Toughness Track Chain (3/32" or 1/8") with internal gear hub? https://www.amazon.com/Izumi-Chain-Super-Toughness-Track/dp/B07YZSPBKN...

From behind and from left side by traffic and from right side and from front by turning vehicles from traffic or from intersections. I was close to such situations multiple times and I saw such accidents. Now, when I have 3000W bike no way I'm gonna ride in the bike lane or on the side of the...

I use Kindernay VII with 3000W Innotrace X1 motor. So far so good. Kindernay VII offers significantly higher gear ratio than Rohloff or Kindernay XIV and you can go crazy fast on Kindernay VII if you have powerful enough motor to crank this bad boy at higher gears. My Innotrace lost juses at 40...

That sucks. That means more danger for bicyclists riding in the bicycle lanes or on the road shoulders along the roads where the speed limit is more than 20mph. It is safer to ride in the middle of the road with tfaffic at 35-40 mph than 20 mph in the bicycle lane or on the side of the road...

Finally I have finished my 80A 52V battery! The motor works! Now I have access to 3000W! It is a monster! The full report with details is here https://www.emtbforums.com/threads/tqfreaks-dengfu-e55-build-thread.32525/page-5#post-480116

Hey evixone, what plug is on your M620 motor and does your M620 motor have original power wires or thicker gauge wires for your 100A setup? When I ordered my 3000W Innotrace X1 motor I additionally purchased XT60 plug option from them but they sent me M620 motor with stock wires and stock plug...

Isn't 3000W option one time purchase? I have to pay for this option periodically?

They set cut off voltage on the motor slightly lower than 0% on display to make sure you won't be in situation when your display gauge still shows some juice but the motor suddenly turns off.

It might. The program might use that value to calculate how aggressively to reduce the power when the battery voltage is close to the cutoff level. Bigger capacity battery allows more power drain at lover voltage level while smaller capacity battery requires more aggressive power reduction at...

So Bafang makes a special controller for Watt Wagons for M620 which is programmed to 2000W nominal and 2300W peak from factory? Why they did not do this before? Is Watt Wagons the only one who is going to distribute bikes with such motors? Are they planning to sale these motors as individual units?

Bafang is going to release new M630 motor with 250 NM torque. I believe this is about the torque of 3000W Innotrace. M630 has same mounting interface as M620 so I guess it is almost direct replacenent https://www.emtbforums.com/threads/bafang-m630-thread.33935/ I'm wondering if Innotrace is...

If for some reason you are going to calibrate the hall sensor position make sure the motor is disconnected from the chain and there are no objects on the way of the crank arms because of the motor will jerk during this process.

Wow. Thank you for you effort! I guess Innotrace got what they wanted. I hope Krasnodar will clarify what is the difference between using this tool and the one is assigned to the server. I can't wait the new battery components to see how strong can pull this bad boy! By the way, how does this...

You mean Krasnodar and Rico work on Vesc app for Innotrace X1 or that person works on such application?

As I understand all the available settings are the same for any firmware as long as you use the same program to setup. I use Kindernay XII gear hub. I use it with 44T Bafang steel chainring (the biggest one fits to my frame) and 14T SHIMANO CS-MX66 DX steel cog (the smallest one fits Kindernay...
