Mercane WideWheel dual motor 2019 rebuild

Post by Sinhu » Dec 14 2021 11:23pm

Hi !

I found a beat’n up ww i paid €50 for and decided to make it the project this winter.

Starting with taken the scooter completly apart, and the list of parts needed became long :(

New main controller
Left side rear rim
1 new tire
Headset bearings
Plastic wheelside cover
Break disc
Down part of dusplay housing

Starting with the suspension, remove the «hot glue» used from the fabric and clean everything. Paint the «fork arms» and using a shore 60 filler covering det springs and joint too the torque arm.

All the «squieeking» noises are gone and it feels softer.

The breaks now works as breaks should :) realy sharp and a plesure to use.

The next issue, lights:

New frontlight as the original lights are not so good. A cheap led light 12-80v from aliexpress ($20) and an solid state rely so i can run it without any extra switch.

As i replaced the trottle with voltmeter with a Wuxing 108x trottle, i wanted to be able to see the batt voltage and have a key for on/off

Installed a 2020 pro keyboks and a volmeter

A lot of work there for a widewheel but guess that this one was about the journey ... an ya did an amazing work by the looks of it. Congrats and don't forget to show some shots of her finished and also curious about how it rides compared to a stock one.

It’s tru thats a bit of work, if you don’t have some parts laying around it would be a bit expensive to.

But one thing is serten, switching to hydraulic breaks and do the suspension makes all the difference too this cool little scooter :)
