Using the Bosch box to charge my batteries makes me feel a bit safer; I also have a fire extinguisher nearby, but just hope I never need neither of them, box or extinguisher ever... I have however inserted a temperature probe in the box and have noticed the temperature rise to 35ºC (91.4ºF) when...

My very modified GUNAI e-bike in one of the very few flat runs over here where I live in Asturias Spain. I'm now saving to get a 20" front wheel so it doesn't look so weird..

I could't sleep well thinking that I could be one of the unlucky e-bikers that burned their garage or even the whole house due to a faulty battery or a bad overcharge. I always charge during the day, but even then, there couldn't be much I could do if one of the batteries set on fire and...

Thanks a lot tomjasz will take a look and find out if I can get them in Europe. Best regards, SpanishFlyer

My GUNAI ShengMilo MX02S came with a sort of torque steel plate on one side, But I was wrong in thinking that that was enough, even after I had swapped the 750W motor for a 1.500W, but I was very wrong... Thanks to the almost sudden squeaky rear brake, after a 37km run, as I arrived home and...

Hi again indianajo, amazed of what happened to you; I thought those things didn't happen in the US... Spain is small compared to your country, but over here we have all sorts of climates and I live in the north, where the Atlantic Ocean brings more water than what we can cope with : ( So you get...

Thanks a lot indianajo, I will surely look for the strongest three way switch. By the way, I've been so busy these past weeks that I had no time to check my mail. I have now finished installing my three 5000W inverters with 36 panels and three Pylontech 3000 batteries and for the first time...

Actually I have already purchased a battery (48V 30A) from Aliexpress and it will arrive whenever it does.... The real reason for asking for advice is on how to connect them so I use one and once it needs recharging I flick a switch and I connect the other; they will never work together. In the...

Thanks for the pics of your beautiful bikes PedalUma; mine looks more like a tractor.... and with the 20" rear and 26" front, it is just as ugly as they can get... ; ) And harryS, both my displays are dead plus one of them stripped open and the USB module removed (see pic). The fact is that...

Thaks PedalUma, I was thinking exactly the same, would never try regen braking ever again; Once I get a new display (hopefully free from the vendor), I will surely leave the parameter 13 to 0 (no braking streght and no energy recovery). What you mention that happened in San Francisco makes total...

Harry, the screen shot was taken once I rode the bike home the second time the bike quit; I started checking everything; the first display I took it apart because it smelt pretty badly of burnt electronics. The only thing I found (as a non electronics expert, by any means), was that the burnt...

Hi again, Just wanted to mention that item 13 on the display is the one that configures the way the motor turns into a generator that charges the battery as you close the throttle and also acts as a sort of brake causing drag on the rear wheel. 0 is not activated and from 1 to 3 goes from mild...

Hi, As I say, I purchased two 1500W kits from CSC with different wheels (20" and 26"). With the 20" on the bike I went out for my third ride, and this time I set the battery charge when decelerating to its minimum (hub motor DD, no gears); I have 1 to 3 options, being 1 the mildest of all...

Dear friend, The bike won't run, but does the display show anything or is it also dead? If it isn't working, it could be a faulty display. In that case if you can grab hold of a display by-pass like the one shown on the attached photo, you can try and have the bike running again (just as a...

I have one brand new one (done 5 miles with it), before installing a 1000W kit that came with its own controller. I'm in Spain if you are interested...

Does anyone know where I can find the Wiring Diagram of the ShengMilo MX02S? After testing the bike with the new 1500W hub motor, I decided to finish the whole wiring installation and when it came to the head light and horn, I found nowhere to connect the double wiring coming from the HeadLight...

I have one and even though it is a great bike for the price, I have a few comments that are not so good but can be sorted out. The biggest one I found is that whatever ShengMilo say, the motor does not produce 1000W and that kills me because I am surrounded by hills and the bike won't make it...

It is like night and day!! with the 1500W DD motor it will almost climb a wall and at no expense of the speed. It has sorted out "most of my problems". I have also included the brake motor deactivation using sensors stuck to the levers, so when I brake the battery is regenerated (to some extent...

I just started my new 1500W motor kit, 0 Km and the grouling noise it makes is quite disturbing; funny thing is that changed the original planetary gear 1000W one, mainly for the lack of power, but I was also looking forward to a totally silent DD motor (I thought). It is nice to know that I...

Have received the new kit with a 1500W motor and exactly the same rear wheel and tyre; now I'm in the process of swapping almost every item since not even the battery connection to the new controller is compatible. This motor does have much thicker wires and the controller is huge compared to...
