Hi,

Sorry, can you tellme what connector do you use, for you charging ? Are your positive and negative trow the connector ? Or just the balance wires? Are you happy with it ?

Thanks,
Luis.

Dlogic · Dec 18, 2013

The socket used for charging is made by Harting and has 42 pins. I pass all the balance wires through this and use 4 pins for the - and + leads.

Finally, the lights are finished and so is the electrical harness.

All that remains is one single piece to fix the headlight on to, this is currently being manufactured.

The blinkers sit at the handlebars end and can be controlled via this aluminum box machined just yesterday.

The switches functions from left to right

1. Blinkers ( left/right)
2. DC-DC converter on/off
3. Regen button ( Green of course )
4. Headlight 3 way control switch ( High beam/off/low beam )
5. Speed limit switch ( 45 km/h and 4 Kw )

Got rid of those bicycle handlebars and installed a motocross one. Gives better control over the bike and keeps me sitting more upright and thus comfortable.
The rear red light shines brighter once the brake lever is pulled.

The Stealth Bomber just had to be chosen as a reference for this custom built version. I believe it´s the worlds most desirable e-motor-bike. Still without any competition and going strong. Keep it running John! :mrgreen:

Just did another test ride today. Love the regen. Incredible that when using it from roughly 87 km/h to an almost complete stop it generates about 3,1 Kw of braking power.

Beautiful Dlogic. You set a great example for all of us.

What caused you to settle on a right side kickstand? After 45 years of kickstands on the left, I'd probably fall down just trying to mount the bike from the other side.

Dlogic · Dec 19, 2013

The kickstand sits on the right side because the spring loaded street legal stuff for the left wiggles up and down when ridding over rough terrain.

My right side version folds inwards and locks tightly. It also looks more stealthish as it hides under the swingarm instead of sticking out and stretching over the rear wheel.

The German Tüv however want´s the spring loaded self retracting version on the left side. There´s one waiting in my workshop to get fixed to the bike today. After they hopefully approve the bike as street legal it will be replaced by the right side version once again.

Allex · Dec 20, 2013

Superwork you have there!
How did you connect brake levers to activate brake lights?

Dlogic · Dec 20, 2013

Hey Allex, the hydraulic hose was cut to insert an hydraulic pressure switch.

Finished the bike today!! Next year the Tüv will do the final inspection.
Made the head light clamp out of sheet metal

Then welded the pieces together.

Here´s the resulting piece attached to the light

Please welcome " Cube ". ( Custom Bomber ) :mrgreen:

Emoto · Dec 20, 2013

Great!! i hope you get as many hours and more of pleasure as it took to make it

Dlogic · Dec 20, 2013

Thanks, so far it rides like a dream. The winter and bad weather are causing a desperate wait for the summer to come back fast. :mrgreen:

Just finished uploading a profile of the bike on Ev-Album

Dlogic · Dec 21, 2013

We had a wonderful winter day with lots of sun inviting both bike and builder to go for a ride to a nearby castle.
A total distance of 43 km was ridden in absolute tranquility on an almost deserted bike path.
I was frozen stiff upon coming back home.

Only 9,7 Ah were used for the trip and 0,874 regained using the regen function.

cwah · Dec 21, 2013

Amaziiing

voicecoils · Dec 22, 2013

Congratulations on finishing the bike!

Dlogic · Dec 23, 2013

Thanks guys. To overcome boredom a new build has just been started. It´s time to use some of the many components that are cluttering up my workspace. :mrgreen:

E-Bike #5.
This time custom everything. My own design.

1. Pinion P1.18
2. 98 cells
3. Custom frame
4. X-5405 ( hopefully coming next year )
5. Motorcycle rims
6. Full suspension
7. Visible electronics as a design element.

But first it´s time to enjoy x-mas and party with my friends at our place entering the new year together.

morati · Dec 23, 2013

Beautiful build Martin!

Looks nice and tidy! i built a liscensed bicycle 6 years ago gas :oops:

but it was alot of work-hassle doing it.im a hack using hacksaws and files,youre build is pro!

best ive seen to date,excellent work dlogic.

Dlogic · Jan 3, 2014

--Thanks to Beast 775 and all the others for the positive feedback. :mrgreen:

Although officially finished, one is never satisfied. So this time it´s the rims and tires i don´t like.
Not that they don´t do what they where made for, but they could do much better.

That´s why some 18 inch Excel rims are on their way to my home, custom cut spokes and these Heidenau tires that have already arrived.

They will replace the Maxxis Hookworms.

Dlogic · Jan 9, 2014

Just finished drilling the side covers to vent the motor.

The 38mm holes have been covered by 8 aluminum discs manufactured on my lathe featuring a total of 608 small 3,2mm holes. These prevent big debris from getting inside. :mrgreen:

Motorcycle spokes are already here too. Once the 18 inch Excel motorcycle rims arrive it´s time to lace up the wheels.

The front hub has been modified to fit these bigger spokes.

Dlogic · Jan 11, 2014

Reassembled the motor. It runs nice and cool now at 8,7 kw/h.
The Excel rims should finally arrive next week.

torqueboards · Jan 11, 2014

This is awesome! Thanks for sharing your build and journey. I definitely like the small BMX style looking bikes better. Great shop skills too wish I was that good!

Did you actually buy a milling machine, lathe and tig welding system?

The battery medics $12 on HobbyKing definitely work well and I actually prefer them over the $30 astro blinky and the Common Sense RC Balancer $20. In the beginning the HK battery medic they seemed like there was a burning smell but after a few times using it. It works well. I've ruined a few batteries as they became unbalanced after a run and I would charge them straight and they would just remain "unbalanced" for the entire time. Not until I figured out that after a run it's best to plug each battery into a battery balancer to get the voltages all the same per cell and then re-charge. Now all my batteries work great.

Wow the turn signals and brake lights are awesome! You are street legal! lol

Dlogic · Feb 5, 2014

Yes, she rides on Heidenau 18 inch motorcycle wheels now.

Handles so much better then before with the bikes tires.

Here´s the old 24 inch front wheel with a Maxxis Hookworm tire compared to the 18 inch Heidenau K65. The wheel diameter is almost identical. Top speed is still the same. :twisted:

zener · Feb 5, 2014

Beautiful!

Can i ask how much Cube now wights? (with or without battery {what battery is it?})
Was the upgrade to MC tires and rims required for the TUV?

Dlogic · Feb 5, 2014

Thanks.

The bike did get a bit heavier with these tires and rims. Current weight is 57 Kg.

Bicycle tires just don´t feel save at these speeds. Furthermore they never transmitted the security and control these babes do. :mrgreen:

Heidenau approves these tires for a max speed of 195 km/h and an axle weight of 180 KG. :twisted:

Architectonic · Feb 6, 2014

Still think it's brilliant.

There might be a modest market for kits of the blinkers/brake lights BTW...

madin88 · Feb 6, 2014

Very tidy and clean build. Respect to the self made frame!

what battery configuration do you have? sorry but i could not read it out..
I like the turn signals in the handlebar. No need to put a second pair of turn lights to the rear. They will be also seen good from behind.
Is the metal sheet under the rear light a holder for a coming number plate?

57kg is a bit heavy i think, but aside from this its perfect...
