Your Creation's Before & After Pics

[AussieJester]

What an unusual looking frame/bike... Why the change from ICE to electric though? Legality issue?
How much less range do you get now (powered alone) than you did with the ICE?

[StudEbiker]

Electric wins again! - Nice battery case at rear frame side like panniers or saddle bags. I appreciate the electric frame geometry so much better... so I guess you won't be needing the stingray (the vette) anymore - jk

-Mike

That's not a Vette. I believe that is a Corvair, which would also explain the handle of "rearengine" which also might explain why he would have an interest in having a bicycle with an engine behind the drivers seat.

[Sturdly]

Hard to tell from the pics. Did you cut up your Cruzebike attachment to move the BB and crankset forward?

[rearengine]

Hey .. Thanks for taking a look.. The frame is MNTB. I went to electric because I didn't like the noise & vibration.. As far as range, I didn't even run a 1/4 tank of gas through it , but we know it would be much farther .. I only ride 10- 12 miles at a time usualy..18-20 mph with the 20" 235 big apple on front.. The battery is setting on a modified rear rack, and a peg on the axle.. The bottom bracket , I cut off of another frame ,and welded it on a flat piece of steel then bolted to the swing arms. The cruzbike kit is on another bike now..The car is a 65 Corvair ( a poor mans corvett ) Take care Bill

PS... Next project

[colby]

Nice bike.
I love your crank idea.

[rearengine]

Colby... It works out real good , easyer on the kneez. Crank forword bikes seem to be coming more popular.. THe way it is mounted makes it reversable also.. Thanks ... Bill

Hi - Have been lurking around these forums for a while researching the best way to electrify my Christiania Trike. Eventually went with an Ezee hub motor kit from ebikes.ca (with great support from Justin and my LBS!). It goes really well and I can now go up hills with a load of children at 20km/h instead of 4 (as long as I keep pedalling!)

That is a really sweet build - my son LOVES it (and wants me to build us one now, 3yr olds - heh).

-Mike

[thatguitarguy]

I didn't take a before pic, but it didn't look that much different. I already had the panniers on, and the brains and power are in the panniers while the panniers hide the hubmotor. If a recumbent can be stealth than this is stealth. People notice that it's a recumbent long before they notice it's electric, if they ever do.

[methods]

Nice. Very subtle.

I am starting to get really excited about the stealth aspect.
If only the 9C didn't whine audio stealth could also be achieved.

[amberwolf]

If only the 9C didn't whine audio stealth could also be achieved.

Does it whine at the PWM frequency or some harmonic/resonance of that? If so, maybe you can use some of the spray-on winding-insulator lacquer to glue them down securely so they can't vibrate. Same thing for the stator laminations (assuming it even *is* laminated instead of solid).

this is the first bike (2007) i built: EB1

48v 12 amp sla
50 amp controller
MY1020Z3 motor
85lb

[colby]

this is the 2nd bike (2009) i built: EB2

4 36v bat836 (soon too be 6. 264a peak)
2 35a controllers (soon too be 1 100a kelly)
2 24v 450w MY1018Z
3 gears on motor side (18-35)
1 speed on crank
50lb

[colby]

both of them...

[bzhwindtalker]

cool bikes! I like the bar you placed under the seat, it breaks the bicycle look

[Microbatman]

Colby
Nice work.
What bike brand is the EB2? Specifically what/who made the frame. Is the frame aluminum or steel?

[StudEbiker]

Colby, nice bikes. Can you post a pic of the "control panel" on EB2. I love rocker switches and stuff like that. Please show us the set up. Thanks!

[colby]

thanks guys!

i really appreciate it.

yeah, they turned out well considering my limited tools and space (hacksaw and a power hand drill) the bracket is kind of my signature for my bikes it definitely has more purpose on the EB1.

i really liked the EB1, but i built the EB2 because i wanted something safer and lighter at higher speeds and have the ability to shift the motors.

the EB1 was heavy as hell and every time you would hit a pothole you thought you might die

EB2 is a 2006 giant pistol 1 with aluminum frame. great bike. hayes hydraulic disc brakes, fox rear shock, etc. here's a link about it:

here's a couple more pics.

charging.



controls:
watt meter
blue=headlight
red=taillight
key=controllers on/off
silver=battery on/off



changes to come:
24" rims with 2.5 hookworms
new custom bracket/battery box and home made seat (kind of like a dirtbike seat)
kelly 100 amp controller...and if the motors die after proper cooling and gearing. maybe a etek/mars or possibly rc. the motors should be fine though (short 4kw bursts with very low gearing) will see though
2 more bosch fat packs (in the mail right now)

thanks for looking

think I'll start a separate thread for this

Giant Trance3 BMC 600 build

Well figured before and after should be done before I had trashed the thing.
Before it was one of these.

Trance-3-Zoom.jpg

Now as an e-bike it looks like this

600Rsm.JPG

After
Building a couple of wheels with 12ga spokes
Upgrading to 8inch brake rotors
Installing a 600BMC rear motor with a crummy axle Déjà-vu
Replacing the MTB crank with a 53-tooth road crank and finding an 11-34 freewheel
Modding a throttle for remote operation
Building my first real A123 pack 2p14s
Installing a rear rack and pack
Fitting fenders that didn't fit.
Putting together a brake motor cutout switch
Modding a Kickstand so it would fit
Putting on a torque arm. and a few goodies lights, speedo mirror ect.

600Lsm.JPG

600R rear half.JPG

600L back half.JPG

Top speed 1st gear locks on at 17mph 2nd gear at 30mph controlled by thumb on the the Shimano rapid-shift front derailleur. Finger lever used to release the locked throttle.
Climbs hills 4mph faster than my GM 500w motor at the same 48V but it is not silent. Cushy ride across the playground, down the dirt roads, off curbs ect.
52lbs with the cable lock, kickstand , 4.6AH bat that gets me near 7 miles at 30MPH. Does not tear my back up like the hard tail Schwinn did.
Still working on;
Battery pack 2
600LM bike light kit
Brake light
5 amp and 8amp chargers as well as 2.8 amp on board.
single wheeled trailer for extra batts and range as well as hauling
lets not forget to replace the hose clamp being used for the torque bar
This build took just over a year and it was done with little use of my damaged right arm. The arm is good enough to ride now so I am doing plenty of it 190 miles so far.
More info on the build viewtopic.php?f=3&t=11478

WOW!!! I Love how you have managed to hide the wires almost magically! I can't see wire ties or anything, how did you secure the main motor wiring? Is it going through passages in the frame like some of the cables do on some bikes?

Beautiful build!! (WE REALLY need clapping/drooling/bowing emotes!!! )

[biohazardman]

I was lucky the rear triangle had holes of the right size and in the right place to feed the motor wires through. Hard to believe when I first saw it. I just had to remove the burrs at the edges of the holes to make it a tight but manageable fit for the motor wires. Wires go into the triangle just behind the kickstand and come out of the triangle and back into the suspension through another factory hole within an inch. There is not much, room for the A123 batteries in the triangle though. Lipo soon to come and they will fit better, take up less space, even with the upgrade from 48 to 60V.

Very Nice! I think I know what full suspension bike to get for my next project, but it's going to be hard to choose since I want an ICE bike too .. hmmm

Very interesting way of making room for the batteries!

I think I might just have to STEAL that idea , I've been trying to figure out where to put 4 more batteries, was already thinking I needed a way to put them on top of the top tube, and your design looks like just the trick, just no trail use right? Hate to see what happens to the family jewels if you side forward off the seat!

[Metallover]

I don't want to interrupt the conversation but here is my build.

I used a mongoose blackcomb, 9x7 rear 9c motor, 12fet 72v 45a controller, 18s 66.6v 10ah turnigy lipo, and I custom made the battery rack.

30-35mph crusing, 37.9mph gps confirmed top speed, uknown range atm,,, I love this bike.
