Here's my build:
It's a city E-Bike with a total weight about 17kg!
Before:
After:
It has a 350W Cyclone motor mounted on a homemade steel motor mount. Top speed is about 40km/h in flat area. All in all i'm very happy with this bike!

Hi,
Thanks! ...yeah I'm from Europe; Austria!
... The batteries are LiFePo4. .. I don't like Lipos on E-bikes because in my opinion i think they are to dangerous.

Haven't got any "Before" pics, but the visual changes are pretty minor, so I'll leave it to your imangination. Wanted to have something visually low-key and understated.
24V 25km/hr geared hub motor on rear wheel.
12S 10AHr Li-Po's (4 off 5AHr in 2S2P) in a custom PVC "down-pipe" battery carrier.
I dont mind pedalling to provide my share of the power, so cruising at 35km/hr, it'll do 60-80km range on flatish terrain.
I use this as a commuting bike, standard ride to and from work is 38km, which I can do in 35 mins each way, and total daily usage is average 2200mAHr back into each pack (ie 4AHr per day).
Pretty happy with this set-up, which will serve me well when being particularly lazy on the cummute home (read couldn't be bothered pedalling).

Nice work on the voltmeter there - and on the install!
If you keep an eye on the e-vents section there'll probably be another Melbourne ride soon - hope to see the bike there if so.
Cheers!

Never posted here because this bike has gone through more changes than I can remember (still evolving, so I guess it's still not 'after')
The feel of the ride is amazing and highlights how crucial a quality bike is to a build, it's hard to do it justice so I intend to change into higher grade components which give a better ride.
Pictured the bike has
12s 25c Nanotech (Good but prefer to change into NMC and I have some ideas on how to improve the bad set-up)
40A 9FET (Noisy square wave and throttle needs smoothing)
Clyte H35 (Too heavy, prefer lighter geared motor that reduces un-sprung weight)
I want to change
Motor
Bafang CST, 9speed quality cassette, white DH-rim, compact and clean.
Controler
FOC custom programmed controller matched to my riding style and has both Throttle and Pedelec so it can be legal when I travel.
Display
With this type of ride I prefer nothing and just to focus on the road ahead of me, but a Speedict would be handy functionality.
I have no problem building bikes for the rest of the world, but have found it hard to build a bike for myself.
That's chalked up to not having a target or criteria (or time), measuring success is smiles per ride is a new form of engineering.

Ha! I thought that was actually your bike when I saw it Joe!
Custom voltmeter install - whats that?
http://www.endless-sphere.com/forums/viewtopic.php?f=28&t=18505&start=210
What's old is new again. I'm very glad they offer a better volt range now with two wire units...
Nice work though Joe. Hope you are staying out of this current victorian heatwave - ack!

Heh! Good eyes Sam
Actually still a three wire, using the 5v controller rail to power the meter (splicing off the multi wire throttle cable or else running from a spare connector (such as pedelec))... haven't looked at the two wires for a couple of years, having dumped em for that very reason of too low a voltage range... must get my searches on again
Yerp it is a bit warm... kinda working in shifts, 6am til too hot... then just bearable o'clock 'til 10pm... least until the concrete slab warms up.. then it's visit friends with AirCon

Older Carbon fiber frame.
Re-used FSA crankset.
25 mm tires.
Cute/QQ M128 rear geared hub - 328 RPM @ 36V
15x39t single speed.
15 Amp controller.
36V 12 ah bottle battery - 432 wh.
20+ MPH.
30 miles range with moderate pedaling - 14 wh/mile.
32 lbs.
First build but not the last!
Thanks for all the info!

How much does it weigh? whats the top speed without pedalling on flat ground?

How do you adjust the tension on the chain as it wears out?
And watch out for the freewheel failing. Those 15t AC Racing have terrible reputation..

What's the current draw of the voltmeter, Joe?
Hope not too high and the 12V regulator is not linear.

Apologies for not seeing clearly. Congrats on a really light build. Is 20+ mph with pedaling or trottle only? Reason I ask is I may change my commuter build to 328rpm

Thanks!
It has a 1/8th chain so I don't expect too much stretching. I used a half link to get the right length but I was also a bit lucky with the spacing.
A bit of locktight should prevent the freewheel from falling out! thanks for the heads-up.

Thanks - can't tell if your sarcastic or not
but if you really do want to know they are Crud fenders...I've since then installed the front one too, which was a bit tricky due to poor clearance. I like the fenders as they keep the electronics (and me) drier during and after rain.

With no resistance the wheel will go 25Mph/39kmh but with me on it (155lbs) on a flat surface it goes around 20mph (full charge) with no pedaling and more with some assisstance. Really impressed with the hub.
I've since then tested a 48V and 60V version with a beefier controller (no resistence speed is about 32 and 40mph, respectively). 60V might be a bit too fast....
To ensure that my hub doesn't give out too early I've also increased the gauge of the 3 phase wires (doubled-up the 14GA wires) and filled the hub with ATF fluid to improve lubrication and cooling.
Can't wait for the snow to melt to give it a spin!

Very nice! I am also contemplating a single speed build on a road frame. 39/15 (68 gear inches) puts you at a nice cadence between 18-22mph. How does it climb un-powered with the extra weight? Still ok if you're willing to stand and bang? Do you find yourself wishing for more or less gear when you switched to electric?

I wouldn't say that it climbs that well. I have a few short "climbs" on my commute which I can manage without the e-assistance - although I do a lot of hill climbing on a normal road bike on the weekends so I don't mind the extra effort... In any case, I had gears on it with a different frame before this one and I never shifted and basically left it in the highest gear.
The OLD with a 7 speed freewheel was 145mm which was a pain to put on and off a steel frame. I wanted to use this carbon frame and so removed the spacer to place a SS freewheel reducing the OLD to 130mm matching the stays. I basically don't have the option on that frame. You might consider a narrower hub like a MAC hub if you want gears.

Hey guys,
I am reading since 3 years on this board. In this time I build and drive my self made bike. I try to poste some pictures. The following komponents I use:
- Bafang bpm1 0... 10000 km after 10000 the clutch was brocken
- Bafang CST 10000...15000km it still works
- LiFePo4 cells A123 48V 10Ah
- EB 309 Controller
- Cycle Analyst
Thats it.
I drive every day ca. 10 to 40 km. For more Information you can ask
so far
