    50cc Scooter conversion

    Well... I thought I should make a quick update. Scoot-ee has now completed more than 500km since going back on the road after the conversion to electric. Nothing major to report (except the previous battery re-configuration work). A video can be found here : https://youtu.be/4QgF20aDRrw This...

    Wow ! Thanks MJSfoto1956 !! That's praise indeed. I'm hoping to put up a link to a YouTube video I've made. I'll try and do that a wee bit later on today or tomorrow. Thanks again.

    So, my original Panasonic 18650 cells, as a 20S4P pack in a 20 cells long x 4 cells wide configuration were, it transpired, simply too awkward a shape to remove and re-insert easily. I designed them this way so that the two packs would lie alongside each other just forward and above the motor...

    Hi SloCo, I think eee291 had grasped my poor explanations in the manner I meant to express them - I most definitely am not thinking of re-fitting a CVT arrangement, just a belt and pulley arrangement a la Zero... but, like I say, with this motor I found I was very limited. Agreed with the...

    Wow ! :O So this is an EV grin ! I'm still picking the flies out of my teeth (yeuch) ! I'm not quite sure where to start. I realise this project was only for a 50cc scooter and by many standards it was pretty simply / basic but I am blown away - not by my work but rather by the result; quiet...

    50cc Scooter conversion

    Having experienced the results of my NOT having done some math (I guess, at the outset, I had just 'hoped' all would be well because it was the simplest solution - not to mention that the conversion itself seemed pretty daunting and I was impatient to start. D'Oh !! ) and having just recently...

    50cc Scooter conversion

    After 'playing about' with the Volt / Amp meter it was time to re-visit the motor 'stutter' and the un-modified clutch. I grabbed my hand-held tacho (nothing special here, 15-oddEuro on Amazon), removed the chain between front / rear sprockets and applied a little reflective tape the motor...

    50cc Scooter conversion

    At the outset I decided it would be really handy to be able to see battery voltage and motor / controller current primarily for test purposes but also whilst riding. However, because I hadn't found a relatively in-expensive meter and because it was simpler at the time and because I really had no...

    50cc Scooter conversion

    Thanks John in CR, Great idea. I THINK there will be sufficient cooling BUT... point well made and taken onboard !! Having very little experience as to how this el-cheapo controller will behave - in respect to both heat and performance/ridability and not wishing to get 'side-tracked', at this...

    50cc Scooter conversion

    On the home straight now ! Just a bunch of wires (all with plugs / sockets on) to connect to the scoot and we're pretty much ready for a dry test ! [1] Throttle / Twistgrip It was day 2 or 3, I think, when I got round to disconnecting the twist grip cable from both the carburettor and throttle...

    50cc Scooter conversion

    This was some fun ! I took some measurements and started designing (SketchUp, again) a replacement fuel filler neck & cap some weeks ago. First I thought I'd use the same Anderson connector as was on the batteries I intended to build (and have since completed). I can't, right now, remember why...

    50cc Scooter conversion

    This week I've been busy with the last major part of the conversion: siting the controller and associated components. The original ICE kit has been removed. The original wiring has been serviced / repaired / updated to remove no-longer required cabling and modified to re-task cabling to suit the...

    50cc Scooter conversion

    With most of the 'boring' stuff out of the way I started off trying to work out where to site the batteries I would be making. Once the site was chosen I'd have a better idea as to final available / required dimensions. I had already played about with weights etc and pre-set any pre-requirements...

    50cc Scooter conversion

    These are to protect the internals form dirt, grit and water ingress as far as practically possible. In the case of my scoot, I have various cover / blank plates to design and fit : [1] Oil pump blanks (I need to design one with a cable (motor) pass-through slot) [2] Starter motor blank [3]...

    50cc Scooter conversion

    I thought that before I start the main / primary EV electrics I should 'tidy up' a little bit first. To be fair, at this precise time, given that I have serious doubts as to the effectiveness (and, therefore, finality) of the scoots gearing, I have decided to carry out the most basic of tunnel /...

    50cc Scooter conversion

    Next came the original / as-fitted electrics and their sorting out and tidying up. Once again, like the strip down, this was pretty straight forward. Unfortunately, the Chinese used a strip, twist, solder and tape method of making joints within the wiring loom. They also had multiple earth /...

    Hi eee291, I just LOVE the look of those JetForce scooters ! I guess they're both using Revolt motors - neat. I was too much of a cheapskate and limited myself to 200Euro of 3Kw BLDC. Look very similar in size, though the Revolts have (at least) double the power at the same voltage (I've gone...

    An update re: my (rather hopeful?) gearing... I'm not sure this will work (given the gearing) but I have to start someplace ! I figure that it will be easier if I can the existing rear variator / clutch assembly (in some modified manner) to pass the drive through the gearbox to the rear wheel...

    50cc Scooter conversion

    Time for an update ! I've made some progress with the motor : The motor controller arrived !! Yaaay !!! Initially, I removed the cylinder head. Once that was done, the swingarm was next. I found it easier to leave the swingarm attached to the scoot for the major kit removal as it helped support...

    50cc Scooter conversion

    Hi Dui, ni shuo de dui, Unfortunately the max power allowed in France is 3Kw / 4.5Hp and I am trying to keep the scoot as close to original / 'in spec' as possible for minimum re-approval hassle. Additionally... it is only for a 15 - 16 year old so 50Kmh would be acceptable, 60Kmh would be (for...

    Hi Bikegirl, Thanks. Sounds even more interesting too ! Here's where I am at the moment; stripped down and ready for some electric kit ! <EDIT> I forgot : I decided (just before the last post :oops: ) to go for a 5A unit - simply because I was trying to keep costs down ! To be fair, a 10A...

    eee291, Thanks for that. Like I say, sounds super interesting. Hope you keep us informed of progress - I'll look forward to that. Good luck.

    SlowCo, Thanks for the encouragement, I'll be back with a load of questions I'm sure. ...and more pics.

    50cc Scooter conversion

    ee291 I was thinking about your Derbi Senda :mrgreen: Please excuse my questions : Super interesed and rather envious; I wish I'd started with a non-scoot although it is (for me) a very interesting project and not too expensive to start-off with. Is it pretty simple to register a converted...

    50cc Scooter conversion

    Hi SlowCo. Thanks for your message. I'm with you re: the CVT belt drive. I 'm leaning towards a chain / sprocket arrangement and am currently thinking of a 17:11 sprocket set-up; the 17 up front, on the motor, and the 11 back aft. I think this should allow a 5000rpm mid-mount motor to drive the...
