Your shop has seventeen different differential models in stock and still cannot fix half the trikes that roll in. The customer brought a no-name brand from a defunct factory. The bolt pattern is close but not close enough. You spend two hours modifying brackets only to find the shaft diameter is wrong. We are Xuzhou Kehuan Electromechanical Equipment, and we built the DB-05 universal
Electric Tricycle Differential Box replacement to end this headache. One adjustable mounting footprint, multiple shaft configurations, and broad voltage compatibility mean the DB-05 fits over 90% of electric trikes on the road today, turning a 3-hour guessing game into a 30-minute standard repair.

Frequently Asked Questions
Q: How do I know the DB-05 will fit the trike in my shop right now?
A: Check three things: motor voltage (48V/60V/72V), motor power (500W-1,500W), and output shaft diameter (measure with calipers). If all three fall within DB-05 range, it fits. For unusual configurations, send us a photo of the old differential and motor label via WhatsApp and we confirm compatibility within 30 minutes.
Q: What if my customer has a non-standard controller from an unknown brand?
A: The DB-05 works with most common hall-sensor and sensorless controllers. For mystery controllers, we offer a free controller identification service: send us a photo of the PCB or model number and our engineers cross-reference it against our database of 400+ controller models. If no match exists, we supply a compatible replacement controller from our stock.
Q: Do you offer wholesale pricing for repair shops buying in volume?
A: Yes. Our universal electric tricycle differential box replacement wholesale program starts at 50 units with tiered pricing at 100, 250, and 500 units. Authorized service centers receive free technical training videos, point-of-sale displays, and extended 24-month warranties. Contact us for a dealer application form.
