Ridstar Q20 or X20 H20 - M5 Settings - Display & Controller 

I just got mine!!! Thanks! I hit 31mph.... bike is huge!!! I thought it was a medium size... I'm 5"10 so I'm very happy!!!

I'm 23 miles into mine and I love it! Great investment! Thanks for the great videos!

Dude thx, i was trying to boost power but accidentally messed up the settings and this helped

Thank you for helping me to fix my bike❤

P10 setting is also handy if you want pedal assist to start quicker. I found out that it takes very long for pedal assist to start working in setting 0 (only pedal assist). With setting 2 (the combined pedal assist and throttle) the pedal assist starts with half a pedal rotation, while setting 0 starts at 3 pedal rotations

Hey B Rich, thanks this is really helpful! Do you think that changing to a controller that allows more than 20Amps would be a good way to get some additional speed out of this? If so, maybe you could link a model of controller that would be suitable? Thanks again

Brilliant,most informative and easy to understand video on these controllers I've seen

Happy I found your site. I just bought 2 of these. The shut down when the brakes are used. One the rear break light stays on, we cannot make this one work. Any advice would be greatly appreciated

I just commented about the wheel size setting in another video on this bike. Seeing you have it set to max power it seems like setting the wheel size to 12 in could get it to 33-35 mph. Also it looks like the seat could be modified easily enough to make room for a gas tank battery. Good for distance but top-heavy for off road.

I just ordered a Q20, should be receiving it in about 1½-2 weeks time.

Thenks for everything you do.

i have a ridstart and everything is perfect besides the battery life. how do i get the full 20 minles throttle only. bc when i throttle and loot at the voltage, it’s taking so much power out temporarily dropping to 46.3 and lower for lower initial battery percentage

Is there a way to set the trottle to work only as the walk mode ie 3 miles 5 km/h. In the netherlands it is only allowed to have a trottle as walk assist or and I am not sure as a small boost till 25 km/h. If not if have to remove the trottle.

Is this RIDESTAR comparable to the bk29 Colorway or HITWAY cafe ebike in the to override the speed setting??

Very nice video man! Thank You for making this! Much appreciated. 🎉

Hey GREAT VIDEO IT HELPED OUT ALOT , question my horn isn’t working on my ridstar what do u think the problem is

Hello I bought this bike and assembled it today but I’m having a P07 code I believe there is a short right between the throttle to the motor. Have you had this issue

Hello, is there an easy way to activate pedal assist cause mine takes so many pedals to turn on and by the time it turns on I will be too tired to pedal.

Nice video! I got my e bike yesterday and Im happy about it. Everything works fine, but the headlight and the honk button doesn’t work, even though I plugged it in. Do you know why?

This works for the Ridstar H20 folding bike too. Was able to increase the current limit to max out the power.

Hey do you know how to turn off the break motor shut off or what wire to cut

Hey B Rich! Just got this bike and was working like a charm yesterday and today. As I was leaving to go somewhere, the power shut off when I was at a light and the screen for the M5 display will not turn on. The battery is fully charged and I also have the 20 Amp model. Any suggestions? All of the connectors are firm and I cant find any wiring issues as I did take the seat off and everything is connected. Now none of the electronic components are working at all.Any help is appreciated, Thank you! (Also was running at 12A/48V before this happened)

Hi BRS I have a question the screen says Energy Bar I don't understand how it increases while driving what mod do i need to turn on for that to happen and is it possible at all. thank you

Since the controller can be 60v max, can i change to 60v batter? Would it get me more speed?

hey, i know you can buy this screen separately, my question is can i wire the screen to a modded mx650?

Dude! An outstanding Video!! Thank you so much!!! Going through the advanced settings to the controller was just a huge help. Exactly what I needed. Especially to achieve the bikes fastest possible setting. I really thought I was going to get more power out of it, since I own a Bagi Bike, that only has a Bfang 500 Watt motor, 48V 13 AH battery and it does 31 MPH no problem. I thought for sure this bike would smoke it, because of the 1,000 watt, much bigger, and more wattage motor, yet it did not yield what I expected. Your thoughts......?

I bought ridstar FM-001, and the voltage shows 54V, no matter I changed the voltage level at the setting P03. Do you have any idea for it? Thank you

Hi, i have bought this bike but how can I take off trottle and turn only pedal assist? Thanks for answer

Hey there, thanks for the video! I'm from the netherlands where we have a lot of restrictions to what is allowed on a fatbike. Faster than 25km/h is not allowed, a throttle is also not allowed if it goes faster than 6km/h. Is there any shortcut to reset the speed settings for when i am pulled over by the cops? I can switch off the throttle in the menu, because i will not be using that. But I need a quick reset option to maximize the speed to 25km/h. Thanks in advance!

I have this bike, how I can limit the speed? 30 miles is way to fast for me.

What does the PAS 1 mean on Home Screen? Peddle assist? If so how do you change that?

Hey B Rich! I just got my ridstar and followed your assembly video, and I have the bike turned on but for some reason the throttle is not doing anything. I am not sure why this is the case and I have all the settings the same as this video, but for some reason the throttle is just not working. I know it has nothing to do with the battery as the display and the lights all work, but like I said I just don't know about the throttle. Please, if you can help me at all let me know!

I just got my ridstar q20 and can hit 30 mph but the speedometer only goes 8.9 and stays there even when im not riding it, is there a setting im missing

Hey there, is there a "walk mode" for the bike? So i can push the bike up stairs and have a little assistance.

I really appreciate your content with budget ebikes. Got my Cruz V8 in Cambodia, it's actually more like this Ridstar with the M5, 1000W motor, but with a hard tail, passenger seat and higher handlebar. Unfortunately i can't change many of the custom settings on the M5; the top speed is hard set at 50kph, but thankfully it's already at 20amps. A motor controller upgrade will surely be complicated as well, I'm rethinking that mod. So, what do you think about the throttle on your bike? Mine is very touchy with a limited range of variability, like a half inch of rotation. I need to be careful as the bike wants to do a wheelie with my partner on board!

Witam.Prosze o pomoc.Mam Q20 od miesiąca.Byłem nim zachwycony ale od wczoraj nie mogę go załaczyc.Nie działa LCD.Dodam że światła działają i klakson.Pozdrawiam

My P15 is set to 41 miles and it will not let me change it. What exactly does this setting do? Does it tell you how much battery battery is left with that amount of mileage?

What are the default settings because I changed mine and some of my only go to 6 miles an hour and then I’m going fast but the speed only shows but I’m going faster than six

I just got this bike and it’s awesome but is there anyway to just have the pedal assist off or no?

Does this model auto reset back to the 25kmh (15mph) setting if u hold the minus and the power button together?

Are you able to actually get 31mph out of this bike? My limit is set to 100k and current is set to 20 amps. But the bike refuses to go over 28mph. Tire pressure is good, I'm about the same size as you, 5'8 185 lbs.

I have a similar frame to the q20 but my display is different are all the functions the same through the menu?

i just got one of these bikes i cant get it to start what ever i do and mine doesn't have a start button on the handle bars like yours i need help before i flip out

Hello Brich, a message from the netherlands😀. I drive the Ridstar Q20 now for almost 2 weeks, its really a great bike and thx for your review over the ridstar💪. I am only not happy with the paddle assist, from a zero start its ok but If i want to paddle again after a corner Or something it takes About 9 sec before the engine is kicking in again. I have Watch your settings clip but its still the same🥲. Do you know something else i van do? Thx

Thanks alot for making this videos, very informative. I have a question, i got the Q20 but my battery level stays on the 1st bar even after charging it for over 6hrs before use, any suggestions?

YO dog! how do you do a factory reset!?? Ive read my manual twice. I just got mine built up, Ill post a vid soon, I think it turned out dope! but yeah my settings only go to 16... I'm doing some experimenting so see what the hell all these other ones are so Ill let you know. GET AT ME though plz.

Any ideas if the only time I get motor power is the walk power?

hello Mr. Rich is it possible that you can show us a mod or a hack to go a little bit faster in a ridstar q20, please?

It appears that an ebike would be a worthwhile investment for me. Riding one appears to be an enjoyable experience, and I believe it would be beneficial for personal reflection and relaxation.

does it have any advance settings that allows you to go faster im thinking about buying one but if it goes faster it’ll be 10x way cooler.

Is this a cadence sensor for the pedal assist or a torque sensor?

Thank you very much for making these videos, very informative. I have a question how you change the percentage of the battery in the screen.

I changed my tire settings to 40 inches when I was messing with the settings and I put it back to 32 and now it says my max speed it says my max speed is 7 mph I don’t know how to fix it

Works on the hitwaybk29m uses same m5 controller thanks a million

Hello I just wanted to say thank you for the video. I had one question for you, so I bought the ridstar q20 from Ali express for 740. I got the 48v 20AH and 1500w model. Do you think I got scammed?

Hi tried it on my Ridstar then the battery shows on the bar and will not charge up anymore, have you had that happen?

So if you set it to a max speed of 20mph would this qualify to be a class 2 bike?

Bought the ridstar a couple days ago and it came charged. Now it’s close to dead and the charger doesn’t work do you know how I could fix it

Can this bike go faster than 31mph with pedaling?

I just got mine in, but when I’m peddling, I don’t feel the pedal assist kick in. Would there be a reason for that?

How do you reset back to factory settings i messed with it and my pedal assist is kicking in late

Good Work 👍👍

is this street legal? I see the 5 settings with 5 being 31mph; what are the settings 2,3 and 4 speeds max

Cool, thanks! My q20 is not kicking in the motor when it i pedal, abruptly enough. In PAS5 I have to turn the crank about 8 whole turns before any assist is present. Is this changeable to be more sensitive and maybe kick in faster?

Has anyone made modifications to go past 31? If so what are the methods you used?

Hey, thanks for the video, can I know if it works in rain ?

Hello sir. I just got the q20 and i was messing around in the settings trying to increase the speed and now it only cycles through 3 speed modes instead of 5 how do I reset it to get it back to 5 modes again. Thx

_Hi, what pressure do you use on your tires?!

Mine came in with arrows and M, can’t reach the P settings any ideas?

Can you do a review and an assembly on the Macfox X1 please

My ridstar came with a much smaller screen on the left side. Settings are still the same. Great bike

I was messing around with my settings on mine and now the speedometer isn't working right how do I reset my bike to factory settings

Waiting for the Amyet S8 review!!🎉

Hello Mr. Rich, sorry to bother you, but is it possible that you can show us a mod or a hack to go a little bit faster please?

The ridstar bike has cruise control settings ?

iv tried looking for a fix to the error 10 ? please help

I have this bike. Do you know the part no. for the brake pads? mine are wore out

Why does my ridstar only go 11 miles per hour I set the ah to 20 and the speed limit to 100?

Hi, I've been following you for a few days but I already love all the videos for Ridstar!! I think you know that in Europe (Spain-Fuerteventura-Canary Island) to be able to travel on asphalt roads we have to limit the power, and here you explained how to do it (for us max 250w) but can you disconnect the accelerator cable? this too is essential to be legal. Thanks for the reply

do you think the q20 lite is any different?

Id be pretty annoyed if i took all this time to make such an informative video only to have people in the comments asking to do things that were clearly explained in the video. 😅 Great vid man 👍🏾

I can tell I'm going about 30 miles an hour but the speedometer saying 4 to 5 Mi an hour how do I fix that I messed around with the settings when I shouldn't have

Having Problems with RIDSTAR Q20 front wheel brakes rubbing with tire disk

It’ll be nice if the written list of all M5 settings are listed, instead of vocally only mentioning? Since most of the e-bikes in U.S. come from China, usually with very poor after-sale customer support, manuals practically not usable and helpful, somebody with enough knowledge about the M5 settings to be able to provide online with written list and what alternative values means for each of the settings, thanks. In the last 6 mo since I’m operating my foldable step-through e-bike I have experiencing burning the integrated front light and LCD M5 display, not allowing me to start the el. System. In both cases Aipas mailed me the replacement parts for A2 Elite e-bike and now keep working.

If i change the speed settings to 25km it doesnt change do you know why?

Man this is nice to figure out I was sent the Q20 Lite instead of the regular Q20 I purchased. Cheers for helping me find that out at least. Wild they actually sent me the wrong bike.

How do you enable cruise control? Mine only goes to p16.

Please help my throttle dont work after trying these settings and I dont know how to fix it

I have a bk29 bike, the throttle doesn't work, it gives me E0007 why, can someone help me?

Mines being weird I did everything you did in this video and I can’t get be bike to into full electric

Can you help me with the controls please? Is there a way to contact you?

my bike only works after being in walk mode and then i have to press the throttle then it works normal if i stop i have to repeat

Could you swap the display for a Bafang?

how much mileage do you get on the PAS5 mode

I just got the ridstar from Amazon and it was a nightmare the screen came broken the battery rail was broken the front breaks didn’t work and the front tire was popped I had to fix all that myself

My bike have a code for advanse setings! Please help me! I only going 25 km/h

Yeah well my friend went to go change the brakes and he had a special order of them from the Chinese red star site we cannot find them anywhere else

Hi ,doesn't the fact that it is 23 inches give an error in the speed?

anybody knows the code for new version of m5 display to enter the C parameters..

when i ride the front wheel sounds like knives sharpening i’m not sure what’s wrong with it
