Rize RX - 2020vs2021 Model?

Any ideas what the major changes are on the new 2021 models for the Rize RX? Do you think there will be a big difference in the user experiences when the 2021 models ship? I am currently in analysis hell but am leaning towards the Rize RX. I just worry they will muck something up with the new model and the reviews will be worse than the earlier model.
 
I’ve ridden nearly 650 miles on my 2020 Rize RX over the past 5 months. I primarily commute 6 miles (one way, couple days a week) on paved back-country roads, but have also taken several week long trips centered around riding 20-40 miles a day split between trails, bike paths, and downtown.

While I can’t speak to Rize support, other than to say I haven’t needed it, I’ve been very happy with my RX thus far.

If you’d like some more specifics on my 2020 RX, here goes - for what it’s worth.

Thing I love the most is how it feels like riding a normal bike, but with a bit more speed. Still feel like I’m getting a modicum of exercise - granted, not as much as with my old MTB, but I’m actually riding regularly, when I haven’t in decades!

Power delivery is fairly smooth (and plentiful). Throttle power tops out at ~28mph, and I can pedal a little over 30 in sport mode with max pedaling effort, but I almost never throttle. I have a e-dirt bike for throttle (and off road). 😄

I prefer to ride between 15-20mph, and rarely move above PAS 1 on anything but longer or steep climbs, where I typically pedal around 8-10mph. 9 speed gearing feels sufficient and can be modulated for level of effort I’m looking for. Love the rapid fire for downshifting 3 clicks, as well as the thumb and finger action for up/down shifts.

One complaint with my bike is a bit of play in pedal engagement. Starting to pedal often feels like some amount of crank travel, say ~1/4”, before hub engages. This could be specific to my bike or I could be misattributing what this actually is. Google search and my non-expert guess is this is due to fewer points of engagement than a higher end bike/hub (or non ebike)?

Brakes are excellent. Plenty of stopping power and excellent feel, with very little throw and minimal effort required. This was my first experience with hydraulic brakes and now other bikes with rim and even mechanical disc brakes feel clunky and squeaky.

Battery life / range seems fine (19ah 48v). Most I’ve managed is 38 miles, down to nearly 0%. I typically ride between 85-30%, around 25 miles - 180lbs rider, PAS1, averaging 15mph, mostly flat. Don't trust the wildly optimistic estimates advertised!

About the only thing I might do differently is consider a fat tire model. My RX is running stock ~2.3” tires and while reasonably compliant on smoother surfaces, it’s a bit jarring on bad roads, and the bike feels too heavy to be pleasant offroad. Bike and battery tip the scales at 72lbs. I’ve only taken it on a couple rutty, downhill runs on stock tire pressure and didn’t feel like the right bike for that type of terrain. I am curious if a Rize RX Pro (or similar fat tire, hardtail) running lower pressure would make the bike feel like it suited every type of riding in a manner I enjoy.

I could go on, but I'm not sure how much that would help since I can't compare to the 2021 model, as you've asked on. I can share that I've ridden a dozen or so ebikes since having picked up my Rize and found they all ride quite differently. That being said, I've yet to ride something I wish I had gotten instead of my RX.

Hope this helps and best of luck on the search!

This is good to hear but can you also turn up the help and feel like you are barely working? I ask because I am looking to get two and my wife sometimes just wants to get from A to B without working hard
Throttle power tops out at ~28mph, and I can pedal a little over 30
Does the 2020 have the same motor as the 2021? Did you have to unlock or tune something to get the throttle up to 28? I thought most throttles were limited to 20mph. I wonder if they tuned it differently because the specs on the website say the 2021 is "Top Speed: 35mph (Throttle)". Not sure if this means the bike is governed to 35mph or if the throttle goes to 35mph. The way it is written it seems the throttle goes 35mph which is nuts.
Brakes are excellent.
Any issues with assembly and the brakes? Someone on another post mentioned to take care when installing the brakes

Thanks for your comment on this. Fortunately for me, I am only riding on the road and paved paths. Definitely something to think about though
That being said, I've yet to ride something I wish I had gotten instead of my RX.
When doing your original comparison, what bikes were you considering instead of the RX? Why did you ultimately go with the RX in the end?
 
RE: 2020 Rize RX: I just used my throttle in a bad rainstorm to get home and I far exceeded 28 mph, running up to the mid 30's. I also regularly ride 40+ miles in PAS 1 Eco and return home with more than 20% battery. Riding environment is very hilly, and rider weight is 225 lbs. I don't think 50 miles in unattainable in the right circumstances, but even this past Winter, I was hitting 40 miles on rides in 40 degree temps.
 
@Kevin8tor is the throttle unlocked for that speed from the factory or did you do some tinkering? I wonder what the absolute worst range would be if using PAS 4-5 the entire time...
 
Also curious if you can change the PAS levels from 5 to 9 in the controller or if you are stuck using 5?
On the 2020, there are only 5 levels in Eco & 5 in Sport. The ability to slice power assist levels up into 9 settings is not actually available, and that hasn't been something that's been an issue. I do believe the display has the capability of showing more power levels, and maybe it's the motor or the controller that is the limiting factor - I do not recall, perhaps someone else does and they can chime in? Nonetheless, I wouldn't describe having 5 levels in each mode, effectively 10 levels, as being "stuck". I have no problem with the assist levels as they are. Eco 1 is good enough for 98% of the riding I do. I wouldn't benefit from 9 power levels when I'm not even using all 5 in each power mode. I almost never go to Sport & only use the throttle in emergencies (typically trying to hurry home in thunderstorms, or heavy rain).
 
I was thinking about it from a "programming" perspective if you buy the cable and use the bafang software. From my understanding, there are 9 levels (plus 0) to program. If you have only 5 levels on the display you effectively can program all nine levels but 5 levels only matter. With 9 levels, you can maybe get better fine tuning. I could be wrong but thats my reason to asking

Absolutely, desired pedaling speed and effort required can be modulated with gearing and PAS levels. What I've found is this effects how fast the bike is traveling, which can be noticeable when traveling with other riders, and require some compromise.
Does the 2020 have the same motor as the 2021?
Yes, same motor, Bafang M620. *Also referred to as Ultra and G510. Zero trouble climbing any hills I've encountered, where I've had friends struggle with 750W hub motors on larger/steeper climbs.
Did you have to unlock or tune something to get the throttle up to 28?
Can't recall if I had to change top speed in the display, possibly - but it's fairly straight forward with not many options.
I thought most throttles were limited to 20mph.
I believe Class 2 designation limited to 20mph throttle, where as Class 3 is unlimited throttle speed and suggested as only legal on private property. Legality was not a factor in my decision, as laws are primarily for people who lack some combination of curtesy, common sense, and/or self control.
I wonder if they tuned it differently because the specs on the website say the 2021 is "Top Speed: 35mph (Throttle)". Not sure if this means the bike is governed to 35mph or if the throttle goes to 35mph. The way it is written it seems the throttle goes 35mph which is nuts.
35mph is doable throttle only. With the added battery voltage, 52v for 2021 vs 48v on 2020 RX, and possible some tuning - I'd guess the top speed is well over 30mph with out pedaling on flat ground.
Any issues with assembly and the brakes? Someone on another post mentioned to take care when installing the brakes
Zero issue with brakes. 600miles+, as strong as they were day 1. No special assembly, no bedding-in performed, or maintenance required for me.
When doing your original comparison, what bikes were you considering instead of the RX?
I compared a ton of manufactures and models, analysis hell as you described it. Spent a month watching/reading reviews, pouring over specs, even made a spreadsheet with pros and cons. Yes, I am a nerd and a bit of a perfectionist. My finalists were: Biktrix Juggernaut, FLX Trail, EBC Model R, Juiced RipCurrent, Surface604 Shred, and Nireeka Prime/Homie.
Why did you ultimately go with the RX in the end?
In the end, I went with the bike that had the biggest battery, most powerful mid-drive motor, torque sensor, and not least of all, was in stock. And, to be honest, I factored in style, perhaps more than I should.

@b1u3 Thanks for the breakdown! Much appreciated. Sorry for the noob question but is the Bafang Ultra (M620) also sometimes referred to as the Ultra Max or is the Ultra Max a completely different motor? I was doing some research on the motor, programming, and such and I noticed a few people referring to a Bafang Ultra Max. Glad to hear you were happy with your purchase. I reserved two 2021 RXs. Fingers crossed they are actually on time for September.

I might be able to share something useful here. I bought the fattie RX Pro (2020), and consider it a mistake. My riding is pretty much all paved, with some hard pack trail and grass thrown in for interest. Bike looks, feels (these are really tall bikes, similar to a 29'er), and handles like it weighs half again as much as it really does. Very noticeable rolling resistance. I'm currently collecting bits to convert the bike to 27.5 wheels.

I have several other bikes (wife and I both ride). After trying several different tires/sizes, all been converted to Schwalbe Super Moto-X 27.5" x 2.4". These tires are the cat's meow. An absolutely great compromise between the fatties and more conventional 2.00" and smaller tires. They not only ride GREAT due to the fact they can be run down to 30psi, they can do that with rolling resistance similar to the Schwalbe Marathon tires I used to run at 60-70psi. There's also a Schwalbe Super Moto-X in a 27.5" x 2.8" size. These have very similar attributes to the 27.5x2.4 tires, and they can be run down as low as 20 psi! I have a set of those for the RX Pro, but haven't run them yet.

My point is, these Schwalbe tires are kinda like a 4" done right for pavement use..... I would highly recommend you try a set before considering a fattie. I'm surprised nobody is talking about them.

Thanks for the intel. I'm really wearing down my rear tire at nearly 1700 road miles. I have the narrow-tire RX, but I do not need knobby, off-road focused tires. I'll be revisiting this thread for tire suggestions in the very near future.

The RX comes stock with 10 levels.

Would the Super Moto X fit a 2020 Rize RX? It currently has 27.5X2.3 tires, but I am looking for a smoother and quieter tire on pavement. Thanks.
 
The RX comes stock with 10 levels.
It comes with Eco mode = 5 speeds, and "sport mode" with another 5 speeds. How the programming is done is explained fairly well in several places you'll want to read, but basically, PAS levels are numbered 0-9 in the programming. Eco (green) mode uses 1,3, 5, 7, and 9. Sport (red) uses 2, 4, 6, 8, and 9.

As far as the ability to run 2.4" tires, I'd pretty much guarantee it. They're just a hair bigger than the 2.3's. The difference is in their construction.....
