Your Creation's Before & After Pics

[AussieJester]

Nice job there mate...little tipz for the seat upholstery (my old man taught me how to recover bike seats years ago was part of his business...) If you have a heat gun or a hair drier set to MAX HEAT you can soften the vinyl and stretch it to remove those creases, if not sitz him out in the sun for 30 minutes ...OH...also a good idea to put a layer or two of Glad Wrap (what its marketed as here in OZ) over the seat before putting on the vinyl cover, this allows the vinyal to 'move' when ya ass sits on it and not grab the rubber and ripz it... Nice bike anywayz well done

I added a new feature to my Specialised and made some other thing better!

I used to have a small switch mounted next to my brake lever for my turbo mode (it control a relay for series to parrallel 33Volt to 66 Volt), I now integraded that in my CyleAnalist(switch under + Green led) + new feature; 2 warning led, Yellow 85 Celcius and Red 105 Celcius motor temp

While I was there, I didn't need the hall sensor (I run a pedal first controller) I took them out and took advantage of the extra space to put bigger phase wire

I'm also replacing the bearing...they are ok...but a bit of play in them and I hate it .

Hewy Almasi, Why not adding a 135Celsius led!

Mine ofted reach that temp when above 3.5kW.. Mine toke sometimes 160+degree and still alive..

This is very conservative at 105 !

Nice circuit for the 3 led

Nice job.
What kind of temperature sensor are you using?

[Doctorbass]

Nice job.
What kind of temperature sensor are you using?

I think he mentionned that he took one coming from a dewalt pack

[Almasi]

Nice job.
What kind of temperature sensor are you using?

I used what i found in the shop...which was a OEM Dewalt Temp sensor. (I tested it at different temperature to find the value vs temp)

I have new clean picture with my new custom made torque arm that use the new stud that I installed for a proper disc brake mount (I used to have cheap 10mm nuts that were getting loose sometime)

I converted a Novara Randonee touring bike using a Cyclone 500W motor. I didn't want to lose my triple up front so I copied the StokeMonkey design:



No freewheeling crank but that's ok with me. Performs great on all the local hills.

Here is the before....

Here are the afters....

Before:

After:


BMC 600 watt hub motor
Crystalite 40A 24-72V controller
Ping 2.0 48V20Ah Batteries (split into 2 packs for pannier mounting)
CycleAnalyst

Speed: 31MPH on flat road.

One year Later:
* Added a new rear air shock to prevent tire hop over the bumps (works great!).
* Moved the battery and controller to the front of the bike, greatly improving the handling.
* Shortened the wires, added thicker phase wires to the motor, upgraded to big Anderson connectors.
* Covered the wires on the frame with matching white tape.

Bike now goes about 34 max. The Ping battery is hanging in there after 2 years and 1000+ miles of WOT commuting. Ok, I do have to accelerate slowly to avoid popping the BMS limiter, but once I get up to about 15MPH I can crank it wide open. Max current is 20A up the big hills.

From Miami's Coral Way Bike Shop (the no-attitude bike shop in town)


single speed coaster brake, steel frame and fork, alloy rims, stainless spokes, Kenda tires,
$200 with included six months warranty (free adjustments)

Now what is next? This bike was fine and easy-gliding as-is. It is good quality, basic bicycle!
Best of all for an e-bike, imo, it is STEEL, where steel counts: a security-plus for curb hoppers and grasshoppers like me.

The next picture to come here in this form in a few days will summarize all the alterations.
It is to be yellow submarine before I'm absolutely finished, or dead, whichever
My world's longest blog thread, nearby here, gives all the stupid details of this fool's ebike build adventures.

[www.recumbents.com]

In the beginning (August 2006), it started with a perfectly innocent Mongoose ($300) pedal/electric motocross bike.


After some massaging (April 2007), it was morphed into a 30MPH recumbent fully suspended commuter. I was able to re-use the rear subframe, wheels, electronics, brakes, etc.


When the cold weather hit, it was time for a fairing (November 2008). This allowed the bike to go 30MPH in all conditions rather than just in ideal conditions.


After 2 years the bike and LiFePo4 battery are still going strong.

My latest build. Just down to the wiring now.

45 pounds 14hp.

Matt

[Doctorbass]

Nice built!!

did you tested the 14hp from the battery? (14 x .746=10.4kW)..

what is the voltage drop at your max current?

Doc

[recumpence]

Actually, the battery can put out more than that. The 14hp I have calculated is controller output.

I highly doubt it will ever see that much power more than 2 seconds while it trys to flip over backward!

I am thinking it will rarely ever hit that much power except for bursts to snap the front wheel up. I normally ride my bikes around 6hp for most accelleration. But, hey, I like the occasional huge power hit.

These cells will probably drop from their 48 volts down to about 43 volts under load.

Matt

[Doctorbass]

Your ebike performance are similar to mine with the 5305 i'm using at 100V 95A.

Usually, I have 6200W on normal acceleration and hit 8500W sometimes on fresh charged cells.

The average power i have at around 65km/h normal ride is around 2600-3300W (5hp)measured on the C-A

Today i've tried one known high hill on Quebec, the speed minimum was 50.2kmh at 4600W... I was right on the max speed limit of 50km/h zone..

On fresh charged cells on the first WOT acceleration the voltage drop to 90V at 95A (8500W) 11.4hp measured on the C-A

What i observed is that by putting battery the lower as possible, the handling of it become very stable,

The battery are 10C rated so the max amp can be up to 230A.. probably at 85V (19.5kW max )and on acceleration i still have enough weight on the front wheel to turn even though at moderate speed.

could you post some videos & more photos showing your build?

recumpence,

Every time I see one of your creations I am unwilling and unable to claim that I'm an e bike "builder". I know I'm just assembling lego by comparison.

[Kaño]

Here goes mine:

Before, ( not the before of before, but before the next picture )

I was a pagan, worshiping the GAS lord! ( wow, that engine was really messy, puagg )



After, I realized I could run by the power of lightning!

[etard]

So sad, it was too late for the dog, the gaslord already took him.

That is one stretched limo, it looks alot cleaner now too. I love it, especially that springer front end. It's a great conversion Kano. Let there be more crossovers!

Is that a geared rear hub?

Whoa nelly, no FRONT BRAKE!!! I don't wanna know, I'm not looking anymore, I'm turning around and walking away...with my eyes still shut.

[Kaño]

well, yes it is a nexus 7 speed rear hub... and as it is an old school style bike, it has no front brake, and the shifter is below the seat!

The " try to stay alive" style!

[Christobel931]

Here's "My first Ebike"... not from Fisher Price

Pretty basic conversion I suppose... works real good. I got the donor bike cheap so was able to get most of the "necessities" right away.

"almost done" Need to shorten phase/throttle wiring.

Aluminum frame and fork... Read many ES horror stories... so now...

This, Surly MTB fork, amped torque arm(not fully secured yet), Kool Stop brake pads. Big Apple tires work as advertised... soak up a lot of the shock.

Topeak MTX with my HTB Battery, and Watt's up Meter, so I know what's up! I think some of the utility boxes mounted as panniers are in the future for security, but at least I can take the big buck battery with me if need be.

This bike is a runner... still breaking in battery, I rode 15 miles yesterday in hilly terrain, only used 6ah from battery. I think I pedal too much!
Motor seems to like running at least 18mph or better so I pedal pretty strong on grades and keep up my speed.

I've had many motorcycles over the years, dirt and street, all long gone now, this bike is just as much fun... maybe I'm getting old

Christobel931

Great job on the build!!!

Looks nice and clean.

Good decison with those Surley forks and using a torque arm. Looks like you did some homework and made the right choice on beefing up how the motor is held in. Using the torque arm and Surly's should help prevent the motor from spinning out and creating damage. Very wise decision.
