Bike: Wired Freedom 2024+,
Motor: Hengtai/Hentach HT-60V-1500W

Long story short, I need the specs for a replacement planetary gearset for my bike. I don't have a gear puller yet to pull this stuff out and take a look so I was hoping someone could confirm this is what I need:

36T Nylon+Steel Planetary Gear Clutch Kit for Bafang 500W/750W Motors - 47.5x12mm Gear with 88mm Clutch Set
Color: Gear Clutch - Left

The motor cable exits from the left side of the bike.

I could also just swap the broken gears on motor 1. I would assume I would just order some 47.5x12mm 36T teeth for that repair.

Quick pertinent damage history of the bike:

Motor 1:
  • Clutch would randomly slip and the motor would whir inside the casing without doing anything. After the motor spun down I could usually rev again and the clutch would catch properly.
  • I 'fixed' the clutch by revving the bike super hard with no load. This caused the clutch to stick permanently, no more freewheeling but also no more slipping!
  • Nylon/steel teeth in one or more gears got damaged 30 seconds from home in one ride
  • Swapped out after ~1000 miles on odo
Motor 2 (Current):
  • Clutch also randomly slips but I found out it's temperature dependent. Clutch doesn't slip when bike is warm. When bike is parked in freezing temps the clutch constantly slips but riding super hard to warm up the motor to >100F usually works
  • I don't think any of the gears are broken yet
  • Display sometimes randomly rounds the temperature to -40F when it's freezing outside
  • Currently around 2000 miles on odo
While I'm 90% sure clutch slip is the issue I can't be 100% sure. I tested bringing just the battery inside vs the whole bike and the clutch slips less while the whole bike is warmer.

Controller 1:
  • Swapped out after random overcurrent errors (suspect this part is actually fine)
Controller 2 (Current):
  • You good dawg!
My rear battery mount also got damaged somehow but honestly with all the crap breaking this is not that important I'll epoxy and ziptie that later.

The bike's over the hill. Very cordial, but the pricing just didn't make any sense hence why I'm asking about a commodity part here and not elsewhere. :mrgreen:
 
If you really like the bike and want something reliable without priority parts. Replace the rear motor with a direct drive hub and I personally believe a mid -drive rear hub combo is the way to go for climbing hills so put a bbshd in the bottom bracket and enjoy the Silence compared to those crazy loud motors.
