I was going to give this a try, but i was only able to find some old polychlorinated biphenyl based transformer oil that was hidden in the back of a seacan. The newer stuff we use in our 69kv-12kv transformers was sealed away in unopened containers :/ They last changed the oil when i was on...

The title is a bit misleading as its still fairly easy to get m620 UART kits from GBK (and likely other sources). I was hoping for a m620 UART firmware that doesn't have as aggressive of a power save mode than the current stock one has. At the moment, once you drop below 47V (with 52V...

Not sure about any UART full bikes, but i was able to get a current m620 UART motor kit from greenbikekit's website. Included the new rotor design, 1000W, and i was able to use one of my already owned eggriders with it to program most settings. Only issue i've been having is a power save mode...

I only started bike riding because my bus times shifted and no longer was able to make it to work on time. I started with a hub motor, but they wouldn't work with where I live in Canada due to the Hilly terrain and wanting to stay street legal. Also the wheel weight plus being on the heavy...

I forgot to add: torque sensor no longer functioned correctly, would randomly function normally then suddenly activate full on for any rotation at all on the cranks. Would also cause the bike to jump forward for a moment when braking to a stop and letting off the brakes. I replaced those...

I ended up retiring my stealth kit because it is unable to keep up with the wear and tear of a daily commuter even with running at reduced power. Heres how's my commute been in 2023 on the CYC stealth... 1200km - Sprag slipping, motor power not engaging drive chain. (2 months out of commision)...

When i had my BBSHD on an aluminum frame, it did loosen off from time to time, and i needed to keep tightening it with my very accurate beater screw driver and hammer :P This may be due to cold flow from aluminum (not sure if it affects 6061 alloy tbh). However on a steel frame it doesn't...

They really don't have much choice on the clutch rating being less than the advertised rating. Even the best sourced clutch for those dimensions is well under 150 nm

I hated running without brake sensors. With torque sensing, it's easy to put too much pressure on your pedals at a light, you end up causing the bike to try to take off. Sure hydraulic brakes can hold it, but it's unnecessary strain on parts. With Regen braking, you save a ton on pad wear...

I've been contemplating using Dexron III in my CYC x1 Stealth gen 3 mid drive to help deal with some thermal throttling i encounter in long climbs (85C peak). The heat drops really quick once the load lessens, so i suspect it is the ~1-2mm air gap between the outer casing and the motor casing...

the part that wore out is not rated for 150Nm, if you look up the specs of the FE433Z2 Freewheel Clutch Insert Element, it is rated for a nominal torque of 56nm from most Chinese manufacturers, or 78 nm from GMN. Likely this is the intended point of failure. Dimensions of the clutch are...

After 1100 km (1 month of use) it looks like the sprag clutch wore out on my stealth gen 3 motor. Had to put my BBSHD kit back on the bike because it was slipping so much i had to walk up steep inclines. This is with running 800watts and keeping the bike in the lowest gears on hills, so its a...

I got my stealth gen 3 a few days ago. Retired my BBSHD that is approaching 45000 km on it. I'm not noticing the noise too bad, when running on street mode with pedal assist. I still have a studded front tire on, so that is louder than the motor. Compared to a BBSHD though, it's louder on...

Just remember that not all vendors who supply the parts will set it up for being backwards compatible. Im still waiting to hear back if the bearing is a 606 as they said or a 609, as the dimensions they gave are for a 609. Oh and that is me who asked on FB lol

It should be noted that in april 2019, Bafang changed their rotor design on the BBSHD and use a larger bearing on the motor stator lamination side. Because of this, if you break your rotor from one manufactured before this date, you will need to order a complete stator+rotor setup. Here is a...
