Good, hello

 

This is the new problem after 400km.

I have a big power loss 25-40%.

I lost flat speed and a lot less climbing power. Climb that I did without pushing more than 20km, mtn I must push.

I will control the wiring, connector, omic value of the motor, controller.

I tell you again. A +

30.5A version?

This brake is a dual mechanical / hydraulic, you have more amplitude with brake lever before blocking the wheel. First, you can try original brake to see if it's enough for you.

Thanks, ordered everything. Do I need any additional parts to install the brake calipers and rotors than what is included here?

Thanks!! How big is the difference between the stock and updated brakes? Could you give some details? I'd also like to know, where exactly to apply the termal pad.

@Leito211 welcome.

There is some heating issues with first controller. I don't know if you will have the last one produced by Minimotors, maybe ask your supplier to know. If this not the case, you need to do some thermal improvements, like using a thermal pad if you're not a mechanic.

You will have no problem to achieve your travel, considering it'a 30.5Ah.

Think to check all screws.

You can also consider to upgrade brakes.

Thanks! Maybe you can provide links to parts for complete brake upgrade + thermal pad?

Hi,

Sorry about me not speak french, but it seems to be the most advanced forum on planet earth about speedway 4. I just have purchased an upgraded speedway 4 52v 30.5Ah from aliexpress. I would like to use it for daily commute (2x20km). I'd like to achieve at ~ 38kmh travevel speed average at least. What should I expect? What do I have to pay attention to? Any mods that I must do upfront for safe reliable long term operation? I'm not a mechanic at all, do not have serious welding or DIY equipment. I would also make it a bit more waterproof to use it in rain if have to.

Thanks for your help!
