The Start Of The Suzuki GT50 Conversion

The bike is going to be converted from 49cc petrol engine to a 3Kw 48v system. The hub motor is going to be the Kelly controllers 3Kw high speed motor. Controller 48v 150A 3kw Kelly Controller. And i am wanting to try and integrate the charger onboard this smallish frame. Soon I'll be able to ride the electric motorbike to school everyday. A couple months ago (more like 2 months ago) I bought a Suzuki GN250, which i was going to use to commute, but after a while of riding it, i found it to be boring. Sold it for NZ$2300. I have been dying to start another project, since i literally just moved to New Zealand. Ok, well lets get onto the project lol.
I'm starting off with a Suzuki GT50, working ICE etc, a lil bit of rust. Not bad for a bike from 1979 :) Bought for NZ$286 ....
Engine coming out:

ENGINE IS OUT!!!!!

At the moment the rego and wof has lapsed out as it has been in storage, so will need to be re registered which will cost a bit :(
So far i have bought this from Kelly Controllers, which I am anxiously waiting to arrive;

Kelly 48Volt Charge Meter                    $19.00   
Throttle Hall 0-5V Twist Grip(WUXING)                $38.00
Optional Waterproof                        $38.00       
F4815-48V/15A Charger                        $199.00   
HWZ Series DC/DC Convertor 48V to 12V 300W            $129.00   
Hub Motor 48V3KW (High Speed)(disc-brake)            $399.00   
Kit for Disc-brake Motor(big)                    $99.00   
Motor Tyre (13-inch motor special) with Vacuum births        $79.00   
KEB48300 150A 48V 3KW                    $209.00   
Low Cost Compact Assembly (KEB/KBL/PM )            $99.00                                                         
                             Sub-Total: $1,308.00 + 277 -----> NZ $2274
Says the high speed motor is rated at 76kmh no load. so should get around 50-70kmh average.

I sold my GN250 for NZ$2300. Giving me enough to buy this. At the moment i am saving up for all the accessories and wire and connectors, which comes to around NZ$150. Once bought, I need to save up yet again to purchase batteries, which accumulates to:

BATTERIES---Scooterparts.co.nz: B-009
4X 12-Volt/24AH  ==============$ 164    Each
Dimensions (mm):
L165xW174xH125          Total: NZ$656

I am going to try to weld a frame around the batteries, using bolts to secure the battery box to the old engine mounts. Making the batteries detachable if needed to be in future, replacement of batteries maybe? I have the idea very very clear in my head and have done a few concepts on paper. I need to make the final design and then I'll post that. I will update on this thread when i do something with the bike, I so far have cleaned up the frame:



Everything will need to be taken off and be sanded down. I.e Rust. Then a coat of primer to be added plus a green sprayed tank etc. Then to get it road legal and more rider comfortable i am going to buy new set of lights all round bike. I am going to be making the wiring harness myself which i will hopefully get right.. lol
No need to ask why i didn't use an etek or similar motor. I have debated that already. I just want to try something different and new, could use creating/converting/selling ev's as my career, and will always need to try new things. :) I really like the bike... It's so slim haha.
Regular updates :)
New ideas would be great and all comments appreciated. thanks
