LOL.. the garbage man took it today. No great loss. I'm hoping greenbikekit can provide a good steel 48 tooth chainring but I've been waiting awhile. Some of the teeth were higher than others on the ali chainring and no, I'm not confusing narrow/wide for poor machining.

My older Haibike with yamaha drive also has the walk assist disabled.. Very disappointing. Why did they do that?

Ali chainring was poorly machined. Well worth two dollars though! :)

That's odd.. I just sent a large package of narcotics last week with no issues

I've been in touch w/ greenbikekit and they are going to get me a compatible 48 tooth chainring to replace the 44 tooth. With it I shouldn't have to use 9th gear any longer with it's few teeth prone to stripping w/ prolonged use. The chainrings from aliexpress are junk

Now I feel like an idiot for buying a Rize RX for $2899...Oh well, at least I got the bafang ultra motor on it. It's a beast

I got my RIze RX about six weeks ago and have now put over 750mi. on it. No failures to date but a few observations. The bike will run over 30mph with the throttle but I don't like using it do to increased drive train wear and increased battery drain. The 15 AH 52 Volt battery is good for a...

I don't see the point of a shift detector if it can't accommodate for the motor after run. I haven't tried a shift while pedaling but if I stop pedaling, the motor is still running for a second, shift and CRUNCH! Either it's too slow or just doesn't know the motor is running

Here's some for 99 cents...

Can't find the order right now, must not be in the system yet. Dang, I forgot to check that this chainring is for 9 speed. Oh well, if it isn't, no great loss

BTW, I found one on Aliexpress for $2.74 so I bought it. I hope it's round and flat :)

Ha! perfect and thanks!

Unfortunately that chain ring doesn't come in 48 teeth.. Oh well

I have a Rize RX with bafang ultra and shift detector. The cutout doesn't seem to take into account the motor decay/overrun so shifts are loud and not nice. I've learned to wait until the overrun stops to shift otherwise I think the drivetrain would be destroyed. I don't know, maybe the shifts...

I'd love to find one in steel for that price!.. All the aftermarket chainrings I'm finding are aluminum

What brand chainring did you buy? Is it steel or aluminum,thanks

I've read that aluminum chainrings wear out much faster than steel but all the aftermarket chainrings I see are aluminum. Point taken on the guard just protecting your pants. I've not had any issues with the chain dropping and I do think the narrow/wide chainrings help

Thanks, I wasn't aware of the rule of thumb. Actually I didn't expect going to a larger chain ring would be a complicated affair whatsoever.

How many links did you need to add to the chain?

Agreed. I did see an outer guard on amazon but it says it's for 42-58 teeth. It must be very tall and then there's the chain stay clearance issue. Will the stock guard work to protect the chain from coming off with a larger chainring? There's a lot of searching to try and find compatible parts...
