Removing speed limiter on Aventura-X EV29 2021 (GoldenLion EV2000 US Version)

(If there is already a thread about this, please let me know! I couldn't find anything, but that doesn't mean it doesn't exist. Thanks!)

Hello everyone! I recently picked up an Aventura-X EV29 2021 (GoldenLion EV2000 US Version) and I absolutely love it! It is so fun to ride and super quiet and smooth; my only real issue with it is that I wish it was a bit faster, even another 5 mph would be amazing! After looking all over online, I found a manual for a German version of this scooter (EFO EV2000) and I translated it to English.

When I opened it up it had this controller (Taizhou Shengtong Type: JS1B2000) which is basically the same that appears in the manual I found (I think the one they show is the EV4000 one):



I haven't been able to find much online about this controller. It also appears to be different than some of the other GoldenLion EV2000 scooters. There is also an electrical diagram, and after looking at the diagram and the controller, it appears to be the same. It's a bit hard to read some of the text and I've started to clean it up a little, but that takes quite a bit of time. What do you all think? Is there anything I can do to make it a bit faster/remove the limiter? I will also attach the manual I found if it could help anyone, that would be great! I also found a second manual (also in German) which is basically the same, but a higher end/faster (EV4000?) manual.

I can only say the same things as in many other "make it faster / remove speed limiter" threads for any system:

Does it run the wheel at the same speed offground as when riding?

If so, it's limited in the controller, probably to comply with the laws where it was sold (or intended to be sold).

If not, then it's power-limited, and the wheel probably spins about 20% faster off ground than while riding.

To fix the former, it's likely that you'd have to have the factory programming software for the controller, and know how to use that software to alter factory limiting. (they make this difficult so they won't be responsible for illegal use of their products).

To fix the latter (or the former if you don't have the software), you'd have to replace the controller (and probably the display and any other parts that depend on the controller itself to do what they do). Most likely the battery is only capable of the original performance, so you will probably have to replace that, too, with one capable of the higher power the faster speed will take.

It's also a voltage issue, in that your motor will only spin a certain speed for a certain system voltage**, so you need a higher voltage battery as well as higher power controller/battery.

**if the new controller is FOC, and supports FW Field Weakening, you can force the motor to spin faster by some amount, but it will be less efficient doing this and cause greater heat in controller and motor, and use up more battery, decreasing your range even more than just going faster will.




To find out how much power it will take to do what you want, you can use the various calculators for watts vs speed / etc such as the simulators at ebikes.ca that can take your riding conditions and specified speeds/etc and show you a guesstimate of power usage under those conditions. This will help you look for a controller capable of the power needed, as well as a battery capable of the power for the amount of time/distance that you need it to to get the range you want at the higher speed. ***

***the higher speed takes more power, whcih goes up very quickly even for small incremental increases the faster you're going, and this means your battery gets used up that much faster and decreases your range.

Thank you so much! I really appreciate it! I will take a look. Odds are I will just have to be ok with it, and that's totally fine!

Normal. Based on reading a number of posts, I think less than 5% of the folks want a solution for going slower. How fast is it now (to determine if more power is part of the limitation, if you find the speed isn’t locked).

It gets to around 32 mph (51 kph). I guess if someone wanted it slower that could be good for battery haha
