Aprilia RS125 conversion, The Jozzbike

[Jozzer]

Acelleraton is very nice, not quite full on sportsbike, but fast enough for now. I'll get the G-Meter strapped on for some 0-60 runs over the weekend!
Insurance taken care of (thanks Malcom, went with footman James as they were easier to deal with and asked less questions. Carol Nash were £20 cheaper, but the idiot on the phone put me off. Repeated all questions 3 times, and failed to understand WHY "someone would convert a nice bike into electric"!)


I've just put Justins new CA onboard, so I will have some figures for range later. Now its insured, I'll also find a fun bit of road to find the top speed
So far Fech, voltage at 80v, and 20AH only. Still loads of room for batts, I've just got to talk Ian @ lifebatt.co.uk out of some more cells

I lied BTW, I still havn't tidied up, think I'll go for a ride instead! (fortionatly not got many customers to see the state of the place yet!)
More soon!

who did your insurance?

[Jozzer]

Footman James. (as stated above). They will cover converted vehicles for the same premium as the original vehicle it seems. Carole Nash will also cover EV motorcycles...

[frodus]

oh, sorry, the second part popped up at me...

I'll check into it once I get closer to riding mine.

Put your vehicle on evalbum... tons of EV Cycles there.

[Jozzer]

65mph with a reasonable headwind...can do better still..
Steepish hill @ 40 on 3/4 throttle, i'm happy with that.
Still no reading from the CA, I had problems with the current and speedo readings, but I believe I have fixed both (user error ). I'll know in the morn.
I've recharged it a couple of times, and it seems I am putting about 1AH per mile travelled back. That works out close to Malcoms 80wh/mile, which surprised me given the complete lack of throttle control I was suffering from! Perhaps its because its much lighter (must weigh it tomorrow!)?

Anyone who wants to come try it, feel free

Sa-weet! Very cool.

[evmotorcycle.org]

Fantastic!

I am really looking forward to seeing some video on your Aprilia! A great choice bike for conversion. Bet it rips along too! Those lifebatts look complicated with all the wires. Does the bike have an onboard charger? How are you charging it? How long does it take?

Varadero Wheels and Rear Sprocket
This is the start of my Electric Honda Varadero Rebuild. My Alltrax controller looks much larger than the Aprilia RS125 version. It's gonna hog some battery space.

WHOA.. how the hell did i miss this thread !!!

Lookin awwwwsome Jozz !!!! but daym... that garage need cleaning !

[Jozzer]

Those wheels look a lot better than they did in the video Andy Whens the motor due? Whats your budget on bike cosmetics?
I am going to build 2 500w CC/CV PSU's into the tank, giving me full charge in 3 hours or so (for the proposed 40AH pack, currently just 20AH, or 2 hour charge). I need to perfect the BMS first though, since they will be mounted together ultimatly. The PSU's weigh about 1.5 KG, anything more powerfull seems to more than double that weight, and i'd rather have more batts instead:P (for that reason I'm glad then I didn't get the bigger controller too!)

Jozzbike made it to 70MPH today, in a dazzling standing start race against my friend Tony on a 1400CC Harley Davidson roadking He barely kept up, giving it all he could before (thankfully) we ran out of road (or he would have eventually sped past at 100MPH!)

THe CA still isnt entirely accurate, the speed readings are bit screwy and I'm having to set the wheel size by guesswork, but I'm getting readings of 125wh/mile with hard use and constant acellerating/braking. Eventually i'll have to see quite how far it will go, but I'll need to be in a more sombre mood

Best of all, i I put on the G-Meter, and got 0-60 timed at 7.8 secs, 0-30 2.4 secs, and it confirmed the max speed on that run at 68MPH. I'll need to do lots of runs to confirm accuracy though, firstly these G-Meters get a bit confused on a bike, and secondly it was dark and I need to see what i'm doing, so I only made a couple of runs (grinning insanely as I held the throttle full on).

Ypedal, I'm beginning to like the workshop this way (actually, this is supposed to be the "lab", theres a big workshop on the other side of the door littered with bikes, M/C's, a sidecar and anything else I thought looked interesting!). I'm becoming fond of the system. No matter what you want, its always on the floor
Still working on the video side...trying to work out how to mount a cam, and how to bribe Tony's wife to sit on the back of his bike pointing a camera at me! Not to mention a nice sunny day..

More tomorrow!

Hi Steve

Looks great!! and the spec sounds really cool! where is all the cash coming from for those batteries!! You and mark arent running other stuff in from China are you hmm what are those life cells costing per cell? would like a 60V pack of them in time.

That bike looks like it will fly, some video of it in action would be great!! the weather at the weekends looks poor so best you go and film some for us tomorrow!!

Cheers

Knoxie

[Jozzer]

Lol, i've been collecting the batteries for over a year (most of my original KMX pack is in this thing!). DocBass tried to help by sending on M1 cells he had gotton begging, but unfortionatly CanadaPost have kidnapped these (been 6 weeks since they got on the plane, and they havn't landed yet ) Theres only 10AH of lifebatts on this that I bought when the first samples were offered last year. Best to buy packs though, ask Ian (Chopperman) for uk quotes, he'll do the best he can

I'm going to buy some more, could do with selling some of the KMX's I have around here (3!) to fund them though...its a slow and expensive start in this business, and i'm pimping myself at my nightjob for all i'm worth! (Musician). I got me a few customers though, its amazing how many halfdead Ebikes there are in a small town! Plenty to fix...
How about you knoxie, worked hard enough to pay for a conversion to your smelly MC yet? Or new girlfriend still too new?

[evmotorcycle.org]

Ha ha! If you are going to be spending a lot of time on the floor then it makes sense to have all your tools there! The cosmetics budget on the Varadero goes something like this… Think of a nice idea, do it, and hide the credit card statements in the bottom drawer! To be honest it only cost about €300.00 for the wheels to be fixed and the swingarm (wheels) cleaned and powdercoated. Which is not too bad. Mind you the Hagon shock cost €350 also. But it was too nice not to have. Mechanical porn if you ask me!

I am using the waiting time for the motor and batteries to fix up the actual bike. Wemoto.com have been a great source of parts. got braided hoses, replacement indicator lenses and all sorts of stuff for it there. I have everything that I need for the bike now. which is good. I even went as far as pulling the extractor cable from an old electrolux down the recycle centre. He he it has an extra long cable for those tricky plug sockets!

The fairing and tank still have to be sprayed but I am waiting for the weather to improve a bit, Oh and also time to work on my spraying skills.

I am looking forward to seeing those Videos of the RS125 performing man (feeling the pressure now ). Stick your camcorder on a tripod and do a few driveby's.

Oh… What colour you planning to paint it?

Andy

[drewjet]

The Perm motor was my first choice, but then changed and decided to go brushless. Your acceleration and top speed has me rethinking my decision.

Andy, Those wheels and swingarm look SWEEEEEEET.

[evmotorcycle.org]

My aim for the Varadero is simple… Pure unadulterated electrical powered mechanical porn!

Malcolm…

Have you had any more thoughts about going for lithium batteries? Your Cagiva Planet would be even more awesome with the extra range.

Andy

[Malcolm]

Hi Andy. Nice paint job on those wheels. I take it you don't want to blend into the crowd?

Have you had any more thoughts about going for lithium batteries?

Oh yes, lots of thoughts, just not enough cash. I've actually got a dozen of the LifeBatt cells myself, just to try out on an ebike I'm working on at the moment. They would look fantastic inside a transparent polycarbonate housing (smoked perhaps), wrapped lovingly around the Etek...

I don't really need a lot of range – although it would be nice of course. At the moment I'd be very happy with a 20AH 72V lithium pack with a 1-hour recharge. That should give me around 20 mile one-way range (taking it very easy), boost my top speed into the mid-sixties and lose around 20 kg from my all-up weight.

[Jozzer]

Aha...I was looking for a nice long lead! (me cuts lead of the old electric strimmer).

The bike will be painted in shocking lime green, with awfull clashing red lettering....just so it can be noticed at the EV rally's when your there with the Varadero

THe Perm is definitly more powerfull than the Mars motor, but of course has a higherprice tag too! What you really want Drew, is one of Todd's AC motors

[drewjet]

MMMMMM......AC......MMMMMMMMMMMMMMM

Unfortunately =$$$$$$$$$$$$$$

[evmotorcycle.org]

Tesla use a brushless motor and that is superfast. Do you guys reckon the brushless motor will be a quick as the brushed eTek version?

Ha ha AC is the way to go… If I open the door and listen real hard I reckon I can hear the sound of a sweet little RGV 250 piston seizing @ 17,000rpm! A potential future AC powered RGV mega track bike.

Malcolm, how you reckon one of these would look with a smoked perspex fairing encased AC induction motor?

There seem to be problems finding a controller for the brushless Etek that can match the original in power.

Also, that would look very sexy .

[fechter]

I want one! Wonder how fast it goes?

I can't remember. Somewhere around 60mph, depending on gearing.
You could ask Todd at Electric Motorsport. He built that one.

The AC induction motor is extremely smooth and quiet. It also has a much wider rpm range than a permanent magnet motor, so one gear works well.

[Jozzer]

I think it peaks at over 40 HP and his E1 (R1 conversion) I believe was good for over 80MPH...

[Jozzer]

Teh Video

Still trying to get the camera angle right, but time to start posting vids.
Unfortionatly, by the time youtube have done there bit the LCD Cycle Analyst cant be read (on the original file it could), but top speed was 60mph. The bike was using 110 wh/mile being abused like this, 80-90wh/mile is more usual on a longer run.

Enjoy
