Looks good but just make sure the controller doesn't overheat, especially with the added power you'll be putting through it - the original controller had its heatsink as the 'coverplate' with only 200 - 250W.

Hi guys, warmer weather is coming! So I laid 3 layers of fibreglass into my mould, set it off with heatlamps and then removed my new upper case from the mould. Oops, guess the mould release didn't :evil:

Hi guys, got my case together today so I charged the 8S 25C Turnigy LiPos using a charger supplied by Hyena. I then took it for a spin, the details are as follows:

Weather 18oC wind from the south at 33 kmh gusting to 43 kmh (normal for Windy-alla) - ride was about 10% into the wind, 10% tail wind and the rest cross wind on mainly flat ground.
27.9 A max, 888W max, 31.3V min, total distance 3.85 km, 1.6Ah used, 51.4Wh consumed, which is 13.35 Wh / km.

Starting volts was 33.2, end is 32.01V with a max diff between the 16 cells is 12mV. I checked the tyre pressures after the ride, 23.5f :shock: and 28.0r :o - should be 40 min to 65 max.

Max speed was probably about 35kmh and the bike could have gone faster just my legs wouldn't! It's worth noting that into the wind, I could get max spin in 4th gear (24kph?) so this is good.
I'll finish painting the case next weekend ( :?: ) and post pics if you're interested.

Edit: and the Hobby King Oz warehouse now stocks LiPo - woo hoo!

Interested to see your Wh/k with your tyres inflated to correct pressures!

wow, didn't realise Hobby King now has a NSW warehouse. Two of these and two 8s chargers + freight are still cheaper than getting the original NiMH battery pack rebuilt and is lighter to boot... http://www.hobbyking.com/hobbyking/stor ... duct=10870

I bought the same packs only configured differently - these Turnigy 5800mAh 8S 25C Long Lipo Pack. I also bought this charger (for balancing only) Turnigy Accucel-8 150W 7A Balancer/Charger, 2x CellLog 8S and a Turnigy Watt Meter and power Analyzer for monitoring.

AND a TPpacks.com LVC/HVC Parallel adaptor, which I'll be "potting" later this week (mind this took me ages to put together, not because of a lack of skills, but the inability to see the holes in the PCB - gotta get a new pair of glasses I reckon). Tools, wires, Andersen connectors in bulk and I still reckon it's been cheaper than fixing the original battery!

Hi Guys, some piccies

Base is made from environmentally sustainable 3-ply, with locating blocks made from 12x12 pine, wrapped with a layer of fibreglass and painted matte black.

The container is made from celloluse fibre (cardboard) wrapped with 2 layers of fibreglass, with some 3mm insertion rubber at each end. On the rear is GGoodman's LVC / HVC board, potted in resin and glued to the battery container.

The container was then painted black and the batteries were added. I then added a layer of insertion rubber and tightly wrapped everything with black gaffa tape. This should prevent any puncturing of the batteries.

Once i had the fibreglass lid removed from the mould (carefully as noted above :oops: ), it was sanded, smoothed, primed (primer filler) and then any imperfection was filled with "spot" putty, which is sometimes called blade or knife putty.

Once sanded, 4 double wet coats of matte black were sprayed (I had this left over from when I sprayed my Falcon GT in 1980!) The paint was then left to harden until today. I then colour-sanded it with 1200 grit wet & dry, and polished it with "buff and shine" for new duco

Nah just polycarbonate cardboard. Light and strong and not messy. Comes in 2 and 4 mm and probably bigger sizes. Used for election signs on lawns.

Thanks for asking about Joyce. She can get it on 2 wheels if she corners too fast but learned how to shift her weight to control it. She is just about faster than me in the corners. She loves the idea of not having to put her feet down to stop. She is mostly healed!

The corrugated polycarbonate is joined with zip ties or wire but it is fairly hard to glue. Cool stuff. There are several folks using it for fairings and some gorgeous Velo's made from it. Check the search function and there will be tons of info. Here is one with a tailbox and front fairing in progress.

Hi HH,

Yes I'm really pleased on how the enclosure turned out, and it was worth the time and effort just to gain the fibreglassing experience. Although as far as cost goes, it would've been cheaper to buy an Aprilia one and hack it!
Yes, it's shame I broke the mould because I would have taken another as this one had some shortcomings, but I spent some time to fix it up and now it's all good!
HVC / LVC control is taken care of by GGoodman's circuitboard, however I couldn't get the throttle to work correctly when it is wired as per the instructions on page 4 of his manual! So I've left my options open for awhile.

Cheers,
GT

I just want to thank everyone for all the information in this thread.

I bought an Enjoy back in 2002, and after the NiMH battery went kaput after about five months, I just parked it. It was a great bike, I did 2090 miles (~3600 km) commuting to work and back. Although it weighs 68 pounds (~31 kg) I got it up to 38 MPH (~60 KPH) downhill one time. High pucker factor with a top-heavy bike going around corners that fast :lol:

I'm not getting any younger (I'm 38) and gasoline isn't getting any cheaper, so I thought I'd figure out how to get her back on the road and get back in shape!

I was going to buy 20 F cell NiMH batteries, which I can find on ebay for about 14 dollars each, I think I'm going to try to go the LiPO route. Cheaper, lighter and more energy-dense. The electronics seems kind of daunting, but I have a bit of experience after replacing the stock Bosch L-Jetronic engine management in my Datsun 280zx turbo with an aftermarket Wolf engine management system out of Australia...

Hopefully someday soon I can post back with the progress. This thread is really a great inpsiration and knowledge source for me.

Thanks again!

Cheers, -Hugh

I've found that most people here are very helpful, and I'll return the favour if and when required. I'm curious though, why did you buy an Aprilia? I mean, you guys have more relaxed laws and aren't particularly known for using little hammers :P

Interesting thread here, glad there are some people still riding these bikes.

My enjoy had it's controller apparently die last fall. Odd, one day it worked, next it didn't. The battery pack is good, however there's nothing with the key turned. It is pulling current from the battery with key in, but no lights, no beeps, zilch.

Oddly enough though if I plug it in then turn it on it will make a beep beep beep noise. Maybe overvoltage.The other clue is last year it would not turn on, but removing and replacing the battery would get it going. It's not the battery contacts, and I have tried booting the controller on a bench power supply with no luck.

Anyone got a spare controller :-) Otherwise I will probably go to some generic and try removing all the potting goo to see if I can fix it (I can repair controllers; I repair 50kw Dolphin electric controllers in my spare time. But they're not potted, just conformal coated)

Anyone else try to repair the controllers or had this sort of failure? I like the assist mode a lot, and turning it into a generic moped is not my optimal goal (though I guess I could get used to it.)

Hi (and welcome),

Can't comment on the symptoms you're having with the original controller (as it was a long time ago since I ditched mine), but I didn't like the PAS. However, I am willing to concede that I could have had a problem with mine leading to that dislike.

I DO though, like having a throttle to control when and how much assistance the motor gives me :) I always pedal but don't always use the assistance, so it doesn't feel like a moped to me!

Sorry I couldn't help you otherwise

Cheers,
GT

If you look back through the start of this thread I posted a link to an Italian website where someone has scraped out the potting and reverse engineered it. You'll need google translate or something to understand it if you don't know Itallian though.

You might want to try dismantling the battery to check all those internal wiring connections ( there are many).
A dry contact inside there gave me similar symptoms for a while.

Yeah, I was thinking that too but he said he tried it on a bench supply and no luck, so that kinda rules out the battery.


On a side tangent, there appears to be a few 'knock-offs' of the motor/bottom bracket drive setup getting around. I have seen the Gette http://www.gettebikes.com/ and the Tonaro (or Torano?) Big Hit that look similar to the Aprilia drive design.

Remember, the Aprilia controller needs a 12v "control" supply as well as the 24 v "power" input.
czach...did you hook up the 12 v also when bench testing ??
