OMG!!!

That's the best first post ever!!

I really like the Cannondale, that's my idea of an E-bike

But where are the batteries going to go? Backpack? Rear rack? Under frame at front would be best for handling.

 

[albie]

I second that... its a really awesome clean setup too!

 

[TylerDurden]

Yeah, those are both pretty-mean.

(Like the weemun I date.)

My commuter/offroad bike,I ride it for go to work and in the evenig before come back to home I enjoy riding it on a trail.

Motor: cyclone 360w
Battery: phylion battery pack 24V 10ah with external ETA ripristinable fuse 20A

Cool rig! Do you get good pulling power with that Cyclone? Background looks really hilly.

 

[TylerDurden]

Nice, Beluga..

You carry the batteries in a pack?

Okay I'm just about finished with this one. Throttle wires still hang about because it's too short, going to need to extend it and then zip tie it close to the frame. The bike is a classic folding bike made in 1978, in Yugoslavia. Bought it for 50 bucks. Should have bargain it down since it was a piece of crap. Spur of the moment thing. I literally scrapped everything on the bike, out went the old spokes, tires, tube, hand grip, brakes, saddle, chains, freewheel and rear coaster brakes. Still don't have a rear brake on. Waiting for its arrival. Folding mechanism was a little wobbly so i drilled a hole and drove a bolt through it, no more folding, but solid as a rock now. This suck because it is one of the reason why i liked the bike in the first place. Oh well i have my Downtube for that. Nearly wet myself a few time trying to stop by using only front caliper brakes. This thing does have mounts for rear caliper brakes so i hope they arrive soon.

Now this thing is running on a brushed Crystalyte 409 20" wheel. I have to say, spoking 36 spokes hub to a 28 spokes rim was a bitch. Truing it was even worse. Controller is Yi-Yun 42-3 Modded with IRFB4110 and 200V rated Caps. If i full throttle this thing from stand still it will wheelie easily. It also easily blow through 40A fuse if i do so too much. Oddly, it feel much faster than my Crystallyte 408 mountain bike on 24" wheel. This is running on the same 66V dewalt pack. It does heat up much more however. Got to work and it was noticeably warmer.

This thing is now back from the past, and with vengeance. Had a few racer eat my dust while on this thing.

Edit: It doesn't look like a POS now, but when i bought it, it smelled like cat piss, chains and freewheel rusted and have some brown crusted stuff on it, i think it was cat poop, but i can't be sure. Took a lot of paper towel and washing to clean it. I'm still trying to get rid of the sticky residue left behind when i remove those decals and sticker.

 

[TylerDurden]

Tut...

that is stealth. It looks like a nuthin POS bike (unless you recognize the hubbie. I'd paint it silver).

No before - just after.

Donor bike is a Schwinn Meas disc (ca. 2002)
The rear disc is replaced with a V-brake (I didn't even attempt to fit it)
Tires are Big Apple Schwalbe (26 x 2.35) which barely fit with the fenders.

Motor is a 408
Controller 72V 20A pedal first IRFB4110 mosfets
Battery is a "non-stock experimental" LiFEPO4 48V 10Ah.
(parts are all from ebikes.ca)

The main problem is that the gearing is too low. Once I hit 26mph, I cannot pedal fast enough anymore

Here's my before and after...

I've been lurking about this forum for a few weeks, and I finally decided to share the current state of my project with this fine group. It's a 500W Cyclone kit on a relatively large (approx 59cm from BB to seatpost bolt) traditional Diamondback frame.

My enhancements include a control box that has twin relays and switches. The relays act like a single high-amperage contactor, and the two switches are enable/Off and ON. The enable/Off switch acts like an emergency off and as a primary power switch to help prevent accidental startup. When the switch is in the Off position, the 3-pin XLR port is engaged to allow charging. That will be necessary once I finish encasing the Anderson connectors in shrink wrap and electrical tape for weatherproofing.

The battery pack is a 24v 20Ah that uses the rare NiMH 'M' cells that are larger than 'F' cells. It was custom made by Rabbit Tool in California. I had to fabricate annular interposers to match the 51mm inner diameter of the battery pack mounts to the 33mm diameter of the downtube.

As an afterthought, I'll upload the circuit for your reading pleasure.

I'm not familiar with editing within this forum, so I apologize in advance for any technical or social faux pas.

X5304 Rear 20 inch disc

Basic bike is Forge that was used for parts to move from aluminum frame to

Steel frame

Picked Azonic Steelhead frame due to having flat 1/4 CromeMoly drop outs to keep the X5 from spinning the wires.

Also had custom torqe plate made.

 

[TylerDurden]

MB... keep heading that direction, and you'll wind up with an "ordinary".

No before, just after:

Starting off with a $129 mountain bike from Aldi, I added a Crystalyte 408/4012 hub motor kit from Brett White and 48v LiFePO4 battery pack from Heter.

Installation was completed to enable the first road trials on 13 July.

The hub motor arrived from China on 21 June, but without the controller. Brett was setting that up locally. The battery arrived from Heter on 30 June and the controller and dual winding relay arrived 7 July.

I installed a front and rear mud guards. The rear mud guard was a bit of a challenge with very little clearance to the 2.3" x 16" rear tyre.

Key Project Challenges:

1. Torque Arms. Crystalyte motor Axle is oversized and the flat of the axle is a firm fit in the frame slot. The torque arms supplied align with the slot. I manufactured a bracket from 4mm aluminiym plate to connect the torque arm to the frame.

2. Battery mount. Fortunately the battery case fits in the frame triangle, so I fabricated a plate on which to mount it. To protect the batttery in case I drop the bike, I still need to fit a retaining bracket at the top of the battery.

3. Dual winding switch. Brett supplied a 40A 48v relay which did the trick. I installed this in a wather proof jiffy box which ended up located between the pack rack and seat stem.

Road Trial Results

The bike was successfully launched on Sunday evening 13th July. I was a bit surprised at the spark when I connected the 10A fuse to make the final connection (forgot about the 1000 microF cap across the controller input). But no fuse blew, so I replaced it with a 40A fuse for the first test run.

All important bits worked. To my surprise, with the on/off switch in the on position, the rear wheel turned when I depressed the throttle.

* On-Off switch installed on the controller works - OK.
* Relay switch between the windings works - OK.
* Left (rear) brake switches disengaged the motor, but right switch (front) failed.

Outstanding Issues
There were, however, two issues.
1. Motor cuts out under load. After a few seconds of full throttle under a little load the motor cut out. Releasing the throttle and re-applying it had the motor driving again.

Finishing Touches
- install connector for throttle/brakes/relay switch to controller.
- shorten motor windings power loom between relay and controller.

hi be very carefull that torque arm will not hold aluminum has no strength, keep all nuts tight each ride try not to throttle to hard and read and keep an eye on the torque arm thread:-http://endless-sphere.com/forums/viewtopic.php?f=4&t=5302&st=0&sk=t&sd=a
edit wrote the bit above first thing in the morning still half asleep reread your post I see the aluminium is used as a bracket that should be ok just have plenty of aluminium round the holes, beware of bending the plate. can you post a closeup of the torque arm on the axel with the nut and washer removed for the torque arm thread I need as much info as possable.

Yes in this configuration,with two chainring,the mtb have 18 gear so you can have a good amount of torque and power.
Probably only 10% of my region is flat land .

Here there is a video(not really good sorry):

Hey guys.. here is my nre ride official 2008 pictures"

I used my small cheap 5mpix Lumix panasonic camera. I waited that the sun goes down for better lightning.

Wich one do you prefer?

Doc

 

[deecanio]

i agree with bikeraider, 766 or the last shot, or just maybe 743?


cheers

[geoff57]

hi all
doctorbass have you used wrenches on your bike to stop the nuts coming off are there torque arms under there as well?
great looking bike I see you are not afraid of having duct tape on the bike, that frame colour and that duct tape matches just perfect.

 

[docnjoj]

Doc! U sure know how to get Hollywood shots! Neat bike, a little too fast for my blood!

[Sacman]

DUCT TAPE!
That's how you know it's a MAN's BIKE!!!

BTW Doc I like 768... somehow it's got that MAD MAX look to it.

 

[D-Man]

None. can't see them.

 

[Doctorbass]

None. can't see them.

Now you should be able to see them :wink:
