Get a narrow wide chainring. Also make sure your chain is not too long, as that allows more chain bounce when shifting or hitting bumps.

What is this narrow wide chainring?

Expensive..

you left the engineered, willing to shift easily derailleur chain ring on? full tooth height chainrings don't make the chain so eager to shift..

why not put FD back on and use it to keep the chain on the chainring.. ?
run the stroke limit screw in to center it over that 1 chainring

You are going to need to give more details.

How much USE is on the chain and ring? Does the ring look worn down? What kind of ring is this? Pics? I dedicated 1x ring should not be dropping. Does this happen AS you shift? Does it matter if it is bumpy? Have you checked the chain for wear?

Google it.

It happens when I shift to the smallest cog...Chain is original & probably needs to be replaced...

Is it the Haanjo Metro? I have a Haanjo Metro, and the chain falls off when on the smallest cog, but only when I backpedal. I can live with it, but would be interested if you find a satisfactory solution. It happened when the components were still new enough to have minimal wear.

Yes, the Haanjo Metro. I got it in a trade last year. I can not live with this issue. Thanks! Knowing that it's been happening to you with minimal wear is good info. In light of this, I think I'll send the Dback folks a message tomorrow..I am thinking of getting that narrow wide front ring, as suggested earlier...

I had the same issue, though infrequent, on my 1x11 road bike. Shimano 105 in the back. Solved the issue to my comfort with a WolfTooth Drop-Stop narrow/wide chainring. They are a bit pricey. I have added one of these to my toolkit for good measure.

Other things to check: Is your frame aligned properly (specifically the rear triangle). Is the RD hanger aligned properly. Adjustment of RD may need some tweaking. Easiest may be the chain - perhaps you have too many links. shortening will increase tension and that will lessen the chance of chain drop. Certainly replace the chain if worn.

On a narrow wide chainring the teeth are taller, and alternate in width to match the width of the chain links. For this reason they are only available in even tooth numbers. When you look closely at one it makes sense.

Pre Indexed shifting Chainrings also have full height teeth , friction shifting skills made them work fine even with more than 1 ring..

another option Surly Stainless steel chainrings ,they're reversable to double the wear life too..

It drops/gets stuck in between the chainring and the outside of the guard and usually takes a bit of handling and tugging to get it outta there. I keep a fairly clean chain, but my hands/gloves require a scrubbing every time it happens.

Same thing here. I removed the bash guard. One possible alternative is, there were some washers between the chainring and the bash guard. Maybe removing those washers would still leave enough space for good operation but not enough for the chain to get stuck in between. I didn't try that, but hung onto the washers.

I might try one of those narrow wide rings. Fortunately my only use of the small cog is going downhill, since it's actually above my top end speed on level ground. Between being a pretty slow cyclist, and the aerodynamic penalty of having a relatively high riding posture, I'm never going to be a speed demon on that bike, though it's the fastest bike I own.

OK now that ^^^ was funny :roflmao2:

I had no idea, a doggone front derailleur with no cable on it is cheaper.

Go get a chain guide. Problem solved.

Are you using a clutch rear derailleur?

Pardon my ignorance, but what is that? Here's a pic:

Same as mine. It's not a clutch derailleur. For the sake of others, here's the Haanjo Metro. Yes, mine is bright yellow:

The drivetrain is relatively entry level, though mine has functioned flawlessly except for the issue noted in this thread. For me, it's been extremely comfortable and fun to ride. It's my only multi-speed bike right now.

Reinforcing my earlier recommendation for a Rehook Tool. https://www.rehook.bike/
