So the information is coming in thick and fast ! so i need time to digest everything . so my photo bucket is fixed for now so i will use this to post progress so watch this space. This is going to be a slow build as i want to tackle each part in bite size pieces .

in answer to some of the questions : i have replaced the deck and fitted a solid plywood deck and grip taped this. this was done on day one of ownership. the last thing i want is to slip of in a corner due to a slippy surface. i have also taken the advice an orderd a thumb throttle as being planted on the scooter will give me full control. I have also picked up a 3 position handle bar switch for toggling the different settings ( jogging speed, traffic speed , and all out hell speed) .

The controller is being planed and developed by EG as this is the brains of the operation and needs to right!
so this is something i am going to read up on for the next .

i plan to research and source all the part after this and lay them out and build it all in one go. Well that is the plan .
Replacing the deck was the first thing I did too. The plastic one was aweful and dangerous.

While you are messing with the deck seal up the battery box so dirt and water can't get in anywhere. Weather stripping is great for this purpose. It's sticky on one side and not on the other. Once you have it supposedly sealed up, spray the scooter down with water and see where the water is getting in. I bet you missed something. It took me 3 tries to get mine to be essentially weather proof. You will never be able to immerse the scooter, but riding in driving rain or through a deep puddle shouldn't be a problem.

Good day to you all , so I have had a bit of time today to fiddle about with my sons EVs and my scooter. For giggles here is our EV fleet lol.

Image

The car has a few areas modified, it runs different 550 motors and a 24v system that is adjustable plus it is also radio controlled for safety. it spins the wheels and runs to about 12mph at full tilt, way to fast for a toddle but is now future proof. The trike is now 12v with a 550 motor and again is adjustable. my son loves them.

So the scooter. First job is to make weather proof and cope with mud and water ingress. So the holes at the base have been tapped up with gaffer tape , the gaps and holes in the chassis and have been silicone up . The deck has been lifted with a few washers to level it off then weather strip has been added to both sides as can be seen in the picture . the result is a very good seal with no major water ingress from the hose pipe. So that is that job done .

Image


I thought I would also add picture of the before I start doing anything else for my refernce as most of the scooter is stock. I was shocked how poor the wiring was it is a joke! This will be replaced along the way.

So Eletricgod has very kindly decided to be my mentor on this build and has offered to support my journey with his vast knowledge and skills . The bare bones of the build are as follows: it will be running a Alien power c80100 80kv motor with support ( purchased) , a 12f “modified and enhanced “ controller with telemetry , 74v lipo set up , running a 219 chain . There will be many little things that get changed and upgraded over the build but I will add these as they happen. All in all this will be a fun scooter when its done and should provide years of enjoyment. The left over motor controller and batteries will go into a kart or scooter build later down the line.

I’m going to accrue the parts over the next few months as there is no rush to get it done (I am poor and have very little money) . The scooter works as it is and does a basic job of moving my bulk around .

i will keep the thread updated i am off for a scoot as i have the day off.

So , I have been picking up lots of little bits from China over the last few weeks such as wires, terminal blocks ,lights, switches ,grips ,bolts, tape ETC but many are yet to arrive due to new year holidays and delivery timescales( photos and info will follow). So the plan is to go with a 20s 20Ah pack made from 5 multi-star 4s packs these should fit in the bay nicely and still give me a little room for wires and other ancillaries. Charger of choice will be something like this:

https://bmsbattery.com/ebike-charger-ev ... arger.html

set up to run 82V so this should give me around 9A of current. I’m continuing to get out on the scooter despite the bitter cold weather we are having here in the UK and very much enjoying the experience. this scooter is now officially slow by my standards granted when it gets to 25 MPH it gets a little more interesting but overall the initial thrill has settled into a complacency . I’m sure this will change over the next few months. That reminds me I need a decent skater helmet.
There really is not very much I can update on at this time but I’m continuing to learn and read on most things Scooter and EV. (baby steps) .
EG your emails of knowledge and information have all been organised now so I can reference this more effectively. You are the ORICAL.

I had a couple of hours tonight to tinker so I took myself off to the garage to see what I could do. So after I decided to fit a smaller rear gear (54 down to 44) to the scooter. So after removing the wheel and a couple of links in the chain I swapped out the rear sprocket and also fitted the original dirt tyre as I mostly take it down muddy tracks at the moment.
Whilst I was at it I removed the pinion gear (10 up to 11) and fitted the stock one giving me 4:1 ( as apose to 5.1:1) . Well I put it all back together and with a full charge I took it out and knowing I would loose acceleration and boy I was shocked this thing was now drawing all the power the SLA 48v had to offer the stock controller and it was slow. It took a long run along a 200m stretch of road to just get up to 22 mph. Where as normally it could hit the top speed (26/27mph) in less than half that . So after putting it away I will be putting back the 54 and 10 back on soon , as this was no fun and won't do the stock battery any good .

Goodnews I have ordered the 219 chain and lube this evening . More parts on the way yippy.

I have now moved to lipo's and i'm running 3x 4s multi-star 16000mah wired in series. This has made a great improvement as there is very little sag and saves a good amount of weight. The scooter is much easier to ride now and is much more manoeuvrable , my advice is ditch the SLAs for lipos . At £45 per pack you cant go wrong!! i am now going to be running my peak voltage at 82 so this should be interesting in a little scooter.

Starting to get excited, as the the modified parts will hopefully be here in the next couple of months! i just have to finish paying for them lol.
Thank you EG for your wise and supportive ways ! you are 1 in a million my friend.

So, a few little things to add to the scooter build:

The first is I have added a MTB 160mm disc and caliper mounting addapter to the front end and after some working out i have managed to fit the disc to the hub. The result is a solid front brake that when pulled alone has no problem bottoming the front suspension out and wants to push me over the bars. The bad part is that in my testing i ran it to full speed and braked hard continuously about 10 times cooking the disc and giving it a very slight warp. But non the less both the brakes work very well and will be reliable for when i add more power.

Second i have tested the 12s 16000mah packs on the standard controller and was amazed at how much range they give over the SLA factory units. honestly if there is one thing you do to your scooter is replace the SLA's with lipo packs! after a hard run of 9.4 miles with my 20 stone of lard at the helm i only saw just under a 5 volt drop over the packs! this was me giving it full speed up many steep hills. plus there was power all the time with no noticeable drop off!


next up i have rewired the handle bars to how i want them for when i get the rest of my parts.

As can be seen i have directional turn signals at the bar ends, new grips, a thumb throttle with voltage output and a 6 button switch cluster set up which will do everything i need ( and also with some spare switches for future upgrades) the controller will be a EG modified power velocity unit ( EG please feel free to add the specs) which will be fully controllable with my phone. along side this there will be a digital "EG" BMS keeping the batteries in check and also the system will be wired up to run 12V for everything but the motor.

Also after a search i found a light green die spring that i have swapped out for the hard stock spring and with a little pre-tension the front suspension now works really well and is much softer that the stock spring. I did have to grind a couple of mm from the bottom to help it clear the frame but well worth the few quid and soaks up bumps like it should. link...........https://www.berger-tools.co.uk/Vl__Ligh ... ight_Load/

so i have a shelf full of bits that are ready for the scooter along with a custom "EG" battery charger.
i have also found this link to be most helpful along my path viewtopic.php?f=35&t=94527

EG if you want to add some tech specs of the parts used please feel free as you have the knowledge around this build.

More to follow soon
