    Hi Ron here, new to the forum.
    I am located in northern NSW Australia and rode a Yamaha RZ for 17 years and am looking to get back into motorcycling in a new way.
    I am looking for some parts to fix up a Megelli 250r frame I was planning to use on an electric conversion. I am missing;
    back shock
    rear subframe
    both brakes
    chain
    rear axle and blocks
    tail light
    side covers
    front mudguard
    sidestand

    I have an engine liquid cooled which has no clutch or starter which was apparently good i can swap or sell if anyone needs it. Hoping someone here can help with parts.
    Also wondering if anyone successfully downloaded the manual from the resources page? Doesn't seem to work.
    I have 6 lithium LiMnFePO4 batteries from a nissan leaf to use and a battrium BMS, a 48V kelly controller and Mars m109 motor, throttle assembly and a contacter and some cabling already, just putting the bike together, found it in pieces with a complete air cooled petrol powered bike to ride meantime. Need a starter and keys for it to get registration for it.
    Parts for chinese made bikes seem to be hard to find.

    Welcome aboard Ron.. to be able to access info from the resources section you need to be a Premium Member.. there is a link at the top of the Resources section.. just follow that.

    Boy.. that is a big project... seems like you are almost needing everything but the frame..lol
    I am interested in how you are going to run the electrics.. I have seen it done very simply with a car but it didnt go too far before needing to be recharged.. Most Electric drive vehicles have regenerative braking etc to assist in power supply.. so as I say.. its a big job.. and if you are wanting to have it registered you will need plenty of input from an Engineer to satisfy our Government agencies..
    Good luck with it.. I will be watching with interest.

    Welcome,
    sound's like a lot of work there.
    What has your engineer said about it all ?
    What are the spec's on the M109, how many kw's etc

    Thanks Bob for that inspiring link, pretty much what I was thinking of doing. I have just now narrowly missed out on getting the Mars motor kit deal finalised in time and someone else got in before me so still looking for a motor. The kit retails at around 1800 so half that was a good deal. Spewin'.
    The Mars ME 109 is a high torque replacement for a Briggs and Stratton 3.5 Hp internal combustion engine and shares the same bolt pattern so it is a shoe in for your ride on mower and a solar panel shade roof would make it complete. It has about 180 Lb/inch of torque and around 15 Hp peak or 8 continuous rated which would do.
    I might contemplate a chinese hub kit back wheel like that guy used. The hub motor would be easier as it would not need a chain or front sprocket. I have a mount I got from one of the electric motorbike racing guys for two Agni motors, they make Cedric Lynch's motors in India, a nice axial flux design permanent magnet motor, they won isle of Mann on an electric bike with such a setup. I'll have to see what turns up.
    The NCOP 14 is a few pages of requirements and is the national code of practice for alternatively powered vehicles and having already had a conversation with the local engineer, (who charges 800 plus gst to go over it for the engineers certificate required to register it btw,) I think it should be pretty straight forward. I have shown him my electric car projects already. Basic requirements are cutoff switches nearby for emergencies, g force activated cutoff like an airbag sensor to cut the HV contactor, a few interlocks so you can't take off with the charger plugged in or turn it on when the throttle is on, orange HV cables and wiring as per the codes, not going more than 20% overweight or too far different from the original weight distribution and you're away. Wiring is simpler than a petrol motor. The requirements for NCOP14 could get considerably more complex as the OEM manufacturers start to make more electric vehicles but for now it is very simple.
    The manual for the Megelli is great and thanks for help re. parts guys, much appreciated.

    The other suggestion would have been to throw away the megelli and go a real bike: something like a zzr250 can be picked up for under $300, or an fzr that doesn't run for a little more style. I've just heard bad things about the megelli - not that I've had one.

    Have you seen Zero Motorcycles? Already on the market, been around 5-10years. But sounds like an interesting project.

    I really wanted a suzuki rg for vintage modified rego and have been looking for donor bikes for some time, not much for much under a grand around and the frame I have for the electric was surplus to an almost complete bike which I thought might save me some petrol in the meantime compared to driving although sounds like I have to look for the crack in the case first before buying a starter (I was told it was all it needed) before I realised the key was missing and the back brakes don't work... I guess I should have done more research on this very forum about the bike beforehand as I paid 800 for both and the spare frame is missing a lot of bits (despite being told it was a complete bike with the engine out.)
    Most of the problems people report seem to be engine related, if it stops and corners it will do for a donor frame. Parts availability for seals for shocks and brake pads could suck though although it looks likely they could become very cheap common "rollers" soon if the engines don't last...
    There are some motorbike like bicycles (stealth bomber) all the way to superbikes (lightning motorcycles) already available in electric drive and the Zero looks great fun. evAlbum.com has a huge list of conversions to check out, it is pretty mind boggling the stuff people have done. the fastest drag things have been electric for some time.
    I rode in a very fast lead acid powered subaru sherpa in Brisbane that was using the same electric parts (and the same 9 inch motor I am using in my rx7 project) from three cars ago (one rusted, one crashed) and he said he had done NIL to it for maintinece in 27 years of driving and 5 odometers in total. The most inspiring electric bike was the Axel Borg effort from Norway, http://www.evalbum.com/3318
    I was so impressed I bought his book on making the motor.

    If I had the dosh I would get one of these Slovenian glider motors but I might end up making a motor like Axel if nothing cheap turns up by the time the bike is ready.
    http://emrax.com/wp-content/uploads/2017/10/user_manual_for_emrax_motors.pdf
    YASA motors England already brushed me off trying to find out how much and then I realised they recently won the contract to supply their very funky yokeless motors to Bugatti for their new hybrid with three of their toughest in it, one for each front wheel and one for the crank of the v16, hydraulic drive diff for the rear. Completely insane 300kw of electric on top of the ordinary Chiron.
    Fair bit of stuffing around doing the battery box and Battery Management System BMS (Battery Management System made by Battrium based in Brisbane) although if you see the nice photos from the conversion bill posted the link to above the leaf batteries are pretty handily packaged; like sardine cans with bolts through the corners and frames top and bottom of the stacks and all the terminals are under the rubber covers on the ends to stop you frying your leg. I am hoping to fit those bits up top which should work with the Megelli as it has a subframe for the motor I can modify. Here is a pic of the project so far, I have the wheels but this is all that is able to be put together at this point before I find some parts, starting to wonder if wrecking the petrol burner might be the best option or if I can fit good calipers from something else. The swing arm is alloy and surprisingly light although the chunky alloy black bit is heavy as and the front red frame is steel as is the missing rear sub frame the seat is on so it is not all that light compared to an alloy box frame from a bigger capacity bike I suspect. Here is a picture of the batteries too; P1050093.JPG leaf%20battery.jpg
