[skyungjae]

it's so difficult to do a before and after picture simply because since my bike is ever changing.

I don't plan on many any drastic changes in the near future, so I guess this could constitute as a potential after picture. :lol:

Link to my build down below in my sig.

Edit April 2, 2013:

Final Form!

Funny how I thought I was done last April. :lol:

I can confidently say that this is the "Final Form!:"

Hi all, first post.

My build is very plug-n-play. All off the shelf EM3EV stuff.

Diamondback Overdrive 29er
10T MAC motor
50V/18.5 Ah Li Ion triangle pack
9 FET / 30 A controller
11T freewheel

My future plans include a Cycle Analyst. I'm too dumb to do much else at this point. I have a lot to learn.

No before pic, but here's one in Flintstone trim:

and mine:

Of course, this is something of a continual project. I'm forever looking to make small changes to free up space, improve the bike, make it more stealthy, etc.

Hi all.. First post and first bike. Got a lot of help in here to order the stuff I needed.

Wanted to build a small, fun, fast, light and "stealthy" bike. The bike is a twenty four seven, light steel frame. 24" Weels. Got two aluminium plates bendt at a mechanical shop to cover battery's and controller. Running at max 5000w and weight is 28kg. Top speed is 70km/h. Still missing front brake(ordered)

-Crystalyte HS3540
-lipo 20s/10Ah
-lyen 18FET controller

 

[Jean Girard]

Very clean, elmarkro. Would be stealthier without the sticker though.

You've got me thinking about painting my bike black.

 

[Elmarkro]

Thanks.. I like what you did with your bike. I have a 29" and was thinking about the same setup.. The flat black made it far more stealth. I might change the stickers but they are pretty much hidden by my lags when i ride it. Big man on a small bike..

 

[Jean Girard]

Touche about the legs covering the sticker.

Painting mine black would do a bit to conceal the battery since the velcro wouldn't stand out as much against a black frame.

Nice burnout

How did you make that triangle battery frame?

 

[Elmarkro]

Nice burnout

How did you make that triangle battery frame?

Its just two aluminium triangles that are bent on all tree sides. They are tighten against the frame, batteries and controller by bolts. I made a sample by cardboard and took it to a mechanical shop. Cost me about 200$. Its really tight and working good. To access the batteries i just open the two upper bolts by wing nuts and the covers still stay on the bike.

$200, they did the cutting and everything for you?

 

[Elmarkro]

Yeah. I just drilled the holes and painted it.

Not sure what you call the kind of mech shop it in english but they do make a lot of metal plate work. Stairs, ventilation, industry etc. They have all the machines they need to do it quick and good.

Nice to see another Overdrive here. Mine should be done by March 1st link in sig to the build thus far. How are you liking the bike itself? I think I only pedaled it once in the driveway before starting the conversion, but did about 13 miles so far on it on test rides. Seat will probably go other than that love it. Did you get a pre laced 700c rim or lace your motor into the stock rim?

When I ordered my kit there was only 26" in stock and I planned on using the stock rim. Now I wish I would of waited 2 weeks on the 700c since the local lbs are chicken to lace it. I think I have it solved though. But rolling with the 26" for the moment.

Hi folks, first post as a noob, first electric bike build.
This was something I really wanted to do, after first seeing Stealth Bomber ads and thinking "Yes please"!
The bike I selected (CBR "Supermoto") was more about the frame than any other component, as it uses a box section 7005 alloy Y-design and I thought it would be very beefy but also easier to bolt components to as it has flat surfaces. As it happened, almost ALL the other components were cheap crap anyway, so i set about replacing them with decent DH bits.


After 888 forks, Sun Ringle rim / hub, Cane Creek 40 headset, Shimano Saint 4-pots, Fox Float R, Crazy Bob's, new seat (yet to be fitted) and a few other bits & pieces like nose fairing with 3200 lumens of Cree headlights, the rolling chassis was ready.


Now the tricky bit - getting the electrics fitted and working - as an electrical theory newbie too, I am entrusting the initial fitting to Simon Askew of "Tank Bikes" (based in Northumberland, England) who is a electric vehicle battery specialist and an E-bike enthusiast.
Hopefully this part will take a few more days and then I can post "after" pics showing the final configuration. Once I have got to grips with the theory, I'd like to modify the frame for a bigger batt. compartment and make it look more integrated.


I'll be using Unknown Chinese make direct hub, 3kw, rewired / waterproofed, with Lyen 18FET controller, 58.8v 15ah LiPo pack, Cycle Analyst v3, regen switch on rear brake , 3- position power switch to help fend off the "5-0" (set for 15mph, 25mph, 40mph approx)
Updates as soon as I have 'em.

Thanks for a great forum everyone - I'm learning a lot. Chris

Bike itself is ok, bought it specifically for the conversion so I was ok with cable brakes and lower-end components. I don't think I'd use it as a regular bike though.

I bought the rim pre-assembled from Paul.

I'm seeing 29-30 mph on flat land just on battery power with a full charge. Not sure how that stacks up versus a 26er. Gonna go poke around your build.

My first build.

1988 Bridgestone MB-4. Old school hard tail MTB. Welded Tange steel frame. No before pictures, but here's the "finished" (are they ever?) product.

12s 12p recycled laptop 18650 cells in a marine ply battery box. I'm pleased at how the box hides almost all the wiring. 65 lbs total weight. "1000 w" 9-C ebay kit.

Roughly $350 in the ebike conversion including batteries and charger so far plus another $100 in incidentals (fenders and headlight).

20mph on the flats, I predict roughly 40 mile range. I think I can get more power from a better controller but it was fun seeing downhill motorists gape in surprise at the fat old man pedaling up the huge hill at 15mph. :lol:

 

[Gypsy]

My newest build is an old Lightning Cruiser I found from a local house run repair shop.

Crystalyte HT35 rear motor
4840 controller
48V 20aH LifePO4 on the rack.
Plan to use some Lipos in the extra space behind the seat tube when I get the funds.

The proud parents...with their ugly but useful child.

 

[winkinatcha]

wow plus 100 for that one Voltron, that is a truly ugly looking beast... I love it

How did you deal with pedal clearance with the smaller back wheel?

I am guessing you jacked it up using a longer rear suspension component... is that right?

Joe

 

[Voltron]

It is a big longer than the original shock... but an unfortunate part of that frame design is the swingarm hits the bottom bracket shell if you go much longer. But since I was just putting it together as an what the hell project, didnt really plan it out too well. Now I know all the things to look for in a frame,,,swingarm clearance for overshocking, room for an even bigger chainring without rubbing (thats a 53, and you can manually flip the chain the inner chaining for hillclimb if the powers out), and beefy from the shock mount to the bottom bracket (bent one frame there). One plus on this frame though is there is a welded cable guide on the toptube that gave a good spot to screw the front end of the battery rail to. I also dealt with the pedal clearance the simple way.. I don't lean over when I'm pedaling :wink:

 

[Voltron]

That scooter motor is terrific btw, having a built in brake saved a lot of hassles, it has an oversize axle, so big flats, the casting acts like a heatsink, and it goes up hill like no other hub motor I've ridden... unstoppable power delivery. It was the same width across the dropouts as a regular gear wheel also, so dropped right in without any frame bending.

Before http://www.reidcycles.com.au/bicycles/create/create-c8-fixed.html#.Ux7Pk4X8mnc
note that the brakes and tyres were garbage.

Mod list - bull horn bars, Tektro brakes calipers (still the wrong size), Shimano SPD mountain pedals, 2 speed sturmey archer rear hub, 1/2 link chain.
new 700x32C slicks with kevlar lining and thorn resistant tubes.
Ebike bits
11.6Ah 48V Samsung pack by EM3EV, 350W 16T MAC and 6 fet controller.
she cruises happily at 40km/h flat no pedaling.
so far little pedaling i get 12.5Wh/km, normal pedaling 7.25Wh/km.

Solar Panel as shown connects directly to the 48V pack no problems, BMS shuts it down when it reaches full charge at 56V or i pull it off at 54V.
Anyone interested its a First Solar FS-382 with 82.5W and VOC of 60V MPP voltage is about 50V hence early in charge cycle pumps in more , as batt voltage rises panel moves away from Max power point and charge current falls off.
at 56V there is only a handful of watts going in hence even if the BMS failed would be difficult to set fire to it

Will post some closer up pics as soon as i get the frame bag to hide all the ugliness of wiring loom.

Bike weight is about 18kg -under 40lbs and with me on it i'm good for 60km+ range at 40km/hr making it a good solution
