The Bafang Ultra M620 is the ultimate motor for your heavy-duty eBike with an incredible robustness, reliability, and power. We have upped the performance specifications to 230Nm and a maximum power output of 2500W, this motor can handle the heaviest loads on the steepest inclines. This is over 60% increase from stock!

With all metal gearing, an integrated torque sensor, ability to use a throttle, and a big/robust motor core, this is the equivalent of a diesel engine in the e-bike world. 

This is the UART version of the motor. CAN version can be found here. 

Available in 48V or 52V versions - you must let us know what firmware you want us to flash prior to shipment.  This will fit other brands as an upgraded motor such as Backou, Quiet Kat, Frey, Nireeka etc but you will have to know which version you have, UART or CAN. The easiest way to tell is to look at your display connector, if it is round, that is a UART protocol, a triangular connector means CANBUS.  

This is a bare motor. Accessories like wiring harness, speed sensor, display, crank arms etc. are NOT included. You need to purchase them separately.  This is a very powerful motor system and would require a battery capable of discharging 50A.

Sturdy rubber ball. Noise maker could be improved
Color: Red
I would have given it five stars because of how much, my dog loved it in the beginning. And shut us up holds true as a sturdy rubber ball. My only complaint is at with one of my dogs being a heavy chewer, she was able to bust the noise making part. The ball never broke open or anything. It just no longer makes noise. You can hear the piece rattling on the inside. The ball itself is still solid tho

POOR QUALITY WHILE OVER PRICED
Color: Brown
Like so many others said, the sound box in this ball is faulty. lasted ONLY for 30seconds. My dog loves the giggle ball I purchased prior so I knew she would like this as well. Well, she did, for that whole 30 seconds. Both of us were so disappointed we could not further our play. Plus this ball was so much smaller than expected for the cost. I would not have minded the cost had this ball been on the ball! Don't purchase this item. Buy the giggle ball instead if you haven't already. UPDATE... Ran across this message at a later date and I would like to thank the sellers at Mewlmart for their response and showing the best business practices as stated in their response below. ----------------------- We sincerely apologize for any inconvenience regarding your order and would like to offer you a full refund for your purchase. If you would like a full refund: please reply 'Full refund'. We hope that you give us another chance. Thank you very much. Best regards, Mewlmart ----------------------- Only thing is I wish I had seen their message earlier, as I believe the window of opportunity for a refund may no longer be applicable. But who knows, they may reach out and still honor it when they review this review. Will update if that happens as it is worth mentioning the extra mile they may take. I am sure I would just then turn around and buy another product from them, giving them another try:)

Indestructible ball….Destroyed my dog’s goals
Color: Brown
I have a golden retriever that would rather watch the world burn with every toy I’ve ever gotten him than play nice with any of them. He burns through toys faster than a cardboard bonfire. However, the trap was set…I bought this as a last ditch effort to show that four legged champion of destruction that he could be bested… I remember it to this day.. It was a Tuesday - raining The ball came in the mail and as I nervously unwrapped and opened it, it was as if he knew a new challenger stepped in the ring as he came barreling towards the front door where I stood. Not today I told myself as I stood with confidence with this ball of justice in front of me. The usual sit and stay kept him at bay until I tossed it to him in which he had turned into a frantic honey badger shaking the ball and chewing ferociously he wanted the squeaking thing inside that doesn’t squeak but sounds like an ugly cry. However, it is next Tuesday and the ball stands victorious My dog has been bested and now understands the chain of command. He respects the ball but will always come back for more until he feels that he has won All in all absolutely buy this for aggressive chews and toy playing dogs.
