Mods and repairs on my Rockwheel GT16 - restoration 2021

[s.m.]

Nobody seems to ride the GT16 these days - I do.

Short version: These two pictures show the same EUC-shell before and after.

This is the continuation from repairs-and-mods-on-my-gt16

The last bigger crash caused one broken pedal (fell off when coming home) and a cracked shell plus a bulged motor cover that led to a left-right slipping axle. Me ? No damage - I was sliding maybe 10m from one big puddle to another all protectors where under my clothing, no asphalt. After arriving at home (YES by wheel) I moved my cloth to the trash bin directly because of the 360° dirt and all protectors were visible. I would say 'no blood = no accident'

I decided to not fix it quick and dirty nor to make any compromises.

I started with fixing the shell by using a smell less 2K product that I use for filling and also for bonding. When I need more
flexibility I just use a bit less hardener while with more hardener it results in an woodlike compound that can be sawed, sanded or drilled like wood without being brittle.
The crack was not small - I laminated a slightly bent screw without head as reinforcement and did the same with small metalplate on another crack (the green marking). The two years before reinforced screwholes survived - just one of the screws was slightly bent.

TENAX® button mod:

After making this cool "quick-open-the-hood-mod" with the button connectors I realized the broken pins on the bottom side.
Rockwheel company is dead, so I do not even think about throwing away any part because something is cracked or broken - I decided to make a hook from 1.5mm steel plate and glued it on.

 

I found an old trolley handle from anything and retofitted it for my GT16 since the old one was very outworn.

 

Next step was the Motherboard compartment and wiring optimization - there was some mess
I added a LED voltmeter for never ever having any questions regarding the voltage of my GT16.

This is the outsourced Light part:

The Motherboard does not deliver enough power for all the white LED lights. I used a relay switched by the original frontlights power.
The relay switches a stepdown converter 84V to 12V/5A that delivers enough power for all the LED's instead.

All parts ready to get coated and paint line is prepared:

 

product mixing:

I stored a little bit into a small tube together with some drops of thinner and no hardener for dipping future major scratches.

Paintjob done:

 

Assembly of high quality easy-running bearings and new tire:

 

Forgot to make the pressing plates from 4mm steel, so ...

 

Then reassembling board and shell. the wiring was a very tricky job, I used surgery-tools which made it much easier.

 

I made the motor cable shorter and added a micro-USB plug corresponding to the new board-sided USB-socket I added before.

 

Now everything possible is reinforced, optimized and in superb condition, there's nothing more to do, I think - maybe 100V-mod or 21700 upgrade.

The procedure of pulling the Motor is outstanding easy in the world of EUC's now: I open the sidecovers without tools and then remove
4 allen screws plus 4 other under the footplates - this is easy done in 2 minutes.
After pulling the motorcable and the usb-hallsensor plug I can pull off the motor and vice versa.
There is only one little thing that is not done, yet - but this will be added soon to make it perfect: optimized toolbox and spare tube-pocket inside the wheel, of course.

No Problem...

This was my first healing-session that demonstrates how to fix damage from asphalt in 5 minutes:

I lost/destroyed one of the hood-opener-buttons and replaced it temporarily with a silver sparepart.

result:

I am satisfied with the result. The small scratches are completly not spottable, while the big one is cleraly visible.

Because of the massive abrasion, it was not possible (and not planned) to rebuild the particular texture in one step.
