my EV projects lol

[phillmoore]

hello all lol i know its 306oc but ive seen a few othepr projects on here so i thought id add mine too
well ive been using electric vehicles for a few years now and ive been enjoying every minute of it so i thought id try and build/customize my own now i dont have welding equipment nor do i have alot of space but ive done a few years of mechanics and electrics at college so ive got a fair idea on the basics with that in hind sight im not thinking of going down the complete custom route like building a frame as ive learnt alot about EV's in the last few years of using them that its not as simple as it seems even when you think you've worked everything out , so i wanted to find people who've had experience in building and customizing EV's and so i thought id ask here , so ill just show what ive used, what im using now and my ideas of what id like to build to see if anyone's got any ideas on what motor to use, controller etc

my first EV a sit on scooter which i bought for a fiver as it didnt have a charger and the batterys were dead from a charity shop





i put on the voltmeter on it myself as it was spare, i didnt have an ammeter and was doing this on a budget
from what i could find out its a very old chinese made kids scooter mine had a 190watt motor which did 8mph max ( thats with pushing lol ) and two 12volt SLA batterys
which the batterys i replaced for 50 quid form ebay and after a few months the motor grinded to a halt half way down a hill which was lovely :roll:
so i replaced that with a 290watt motor i used this for a few more months then wanted something a little more faster so i could actually use it on the road without being dangerous

so i got this from ebay its a evo powerboard x1000





disc brakes front and back and suspension



disc brakes front and back and suspension



front mono shock



power indicator with red button for 15A/30A



i had alot of fun on this got alot of looks and as it was electric the police let me use it as long as i used bike signalling and laws etc on the road so i used this for about a year to and from work and on a few occasions took it through muddy trails and once or twice over a dirt jump track near were i live in east sussex which was a right laugh but i did scrape the under side a few times as it only had ten inch wheels
1000watt brushed motor
1000watt controller with switchable 15/30Amps
ten inch tires
front and back suspension and disc brakes
alloy deck and bmx style handle bars
capable of 23mph with me (10 stone) rider on flat ground on 30A mode
3x 12volt SLA batterys
weighs about 40 kg

of course the problem i soon ran into with using this as a means of commuting and pleasure was when it ran out of battery whilst commuting or half way through a trail ride so i realised that id need another means of drive instead of lugging a very heavy scooter home to charge so i looked into electric bikes and bikes in general so that i didnt spend money on a bike that would fall apart after some time also known as BSO's ( bicycle shaped objects : things that look and appear like bikes but arnt due to being so cheaply made that they fall apart within a year or less ) so i looked into downhill/trail bikes and also dirt jump bikes as i know at some point my bike will be going through muddy trails and the occasional offroading that may include small drops ie some punishment to the bike but not alot as one i dont have alot of it around the south coast and ive got an 18 inch titanium bar in my left leg from the ankle up to my knee from breaking it in multiple places two years ago and its basically healed but it cant deal with large impacts without giving me a lovely shooting pain thats quite...fun to say the least but i dont let it bother me whilst i ride as it keeps the leg strong for work and general fitness
hence me wanting an electric bike thats capable of powering me to and from work if my legs playing up and the occasional trail ride at least if not a full offroader

well i bought this bike off my mate for a tenner as he got it from a house clearance so i can choose the base style of bike i want later without wasting money on a brand new bike with the wrong frame



a dirt jump style BSO in a very bad shape



no back brake lever and no front brake at all, the front lever is connected to the back brake



just to point out the tire isnt a white wall tire it looks like it because the back brake was rubbing on the tire to brake not the rim i got it this way so who ever owned it beforemy mate didnt look after it at all

---

and the lack of the front brake assembly

so i went out and bought 90 quid worth of stuff to get it ride-able










i then went and bought a 250 watt front wheel kit from ebay with a 36 volt 10 ah lipo battery and mud guards then fitted them to the bike










ive got the thumb throttle close enough to the gear shift that i can lock it on full power like cruise control for when im on long flats etc, im currently using this to get to an from work and the occasional trail ride but id like to get closer to the power i had with my scooter 1000w or so , id looked at a magic pie 3 motor that did 24-48 volt and 250-1500watt with its built in controller and regenbraking with lipo4 battery etc for 800 quid seemed like a good idea but i dunno what magicpie 3 motors are like or golden motors etc any ideas or suggestions would be very helpuful im in the uk so i dont really want to pay import costs id like something similer to the magic pie 3 with around 1000w+ power/ 30mph would be lovely as i think it would help with my leg on bad days and battery wise if i cant mount it to the frame because of balance problems id use a backpack with waterproof connections etc thanks in advance for any help

and ill add my micro EV scooter projects once ive got some photos as i ve got the bikes battery now mounted in a backpack (some of you may have already seen the pack when i was at ace cafe last ) added to that there's my upcoming solar backpack which i could charge the scooter with or use any other household electric appliance up to a max of 300watt which im planning on using for my trip to the french car show in july

Nice to see you finally got this thread up phill!

Should be a laugh seeing you zip about at FCS on your scooter, might have to ponce it off you as well!

For the benefit of the other members, phill and I have joked about how we balance out each others carbon footprint....him on his leccy scooter at one end of the scale, and me coaling past in the dt at the other!

take the scooter to pugfest and see if you can get a run up the hill
