Complete mid-drive conversion kit, just removed from my bike. Everything you need to turn a regular bike into a torque-sensing e-bike.
The TSDZ2B has a built-in torque sensor, so it feels like natural pedaling, not on/off "throttle" power like cheaper cadence-sensor kits. Smooth, quiet, and great for hills.
Included:
Tongsheng TSDZ2B mid-drive motor, 48V, with chainring and crank arms
48V 15Ah (720Wh) downtube lithium battery with mounting cradle and 2 keys
Battery charger
Color LCD display with handlebar mount
Thumb throttle
Pair of brake levers with motor cut-off sensors
Speed sensor
Grin Tech "Double Bob" battery mount (made in Canada, ~$40 new); lets you position the battery where it fits your frame
XT60 to Anderson adapter cable
Mounting plate, lockring, and spacers
Pedals
Condition: Used about 10 miles, works great. Battery holds a good charge. [Reason for selling: going back to the original parts on a vintage bike.]
Fit: Mounts in a standard threaded 68–73mm bottom bracket shell. Check your frame before buying.
Local pickup only (can't ship lithium batteries). Cash or Zelle.
