My friend just this weekend installed the quiet gears in his Ultra (CANBUS) which was very noisy. Now his Ultra runs near silent. YMMV.

Oh yeah, I'vebeen working him on that! He's got that primitive rear cogs and derailleur thingy! :)

My riding partner has ridden a Sondors Rockstar with a Bafang Ultra (CANBUS) for the last three years. We've been riding together about 4 times per week. I've always teased him about the excessive motor noise that his Ultra Motor makes. We both ride with SENA Bluetooth communicator helmets and I...

Looks like a Hailong battery which is good. They are widely available.

I don't know anything about those bikes, but on thier parts page it looks like they use the "KT" controllers which are ubiquitous and easily sourced. That's a good thing.

Why don't you share the make, model, and price, and maybe some other members that purchased that make or model can give you some specific insight?

congrats. That motor is a lot of fun.

I almost ride every day, weather permitting. I ride 70% with my my neighbor who has a comaparable eMTB, and 30% alone.

Hey thaks for the feedback. The hub is sweet and I am stoked every time I ride at how precise the shifting is while riding very agressive mtb trails. Never a missed gear, always the correct gear on demand, whether moving or at a dead stop. Yes I was pleased to see the oil requirements were...

I added a second battery 13 months ago using this battery balancer from Amazon. I'm using two 48V 17.5Ah batterys for a total of 35Ah's. It has worked flawlessly.

It's been 15 months since I installed the Rohloff hub on my Luna Z1 eMTB. The hub has operated flawlessly without a single adjustment. I really love this hub and could never go back to the ol' derailleur system.

Nice! Enjoy...

No, there is not, except for you, test driving each bike and motor before buying. I recommend that you purchase from a local LBS. Test drive and compare their offerings.

That's nasty!

It's getting dicey!

Congrats on the change up. The Bafang Ultra is a pleasure to ride. I've been riding the Ultra for 2+ years now on my full suspension eMTB. Zero problems, always plenty of power to get the job done. I rode the Bafang BBSHD for two years prior to that, same power and torque. Still runs flawlessly...

Yes

Considering motors don't actually have a "watt rating" the answer is "no". Watt ratings are BS, and each manufacurer could use differnet measurement standards if they want to. If you are buying a motor, controller, or battery(BMS), you should understand the nominal and peak operating parameters...

OEM Tourque "ratings" are not indicitive of speed. I believe the addmotor is a rear hub drive? Rear hubs can be very fast, and can ramp up speed quickly, often faster than mid-drives. I ride an eMTB with a Bafang Ultra mid-drive rated at 165nm. I have an Aventon Level with a 90nm rear hub motor...

Thanks, good to know
