Sockman's build

[sockman]

Its been a while...finally managed to complete most of the stuff and went out for a test...hit 34km/h easily

My component list
Kona Caldera 26" (left only the front disc)
Matt's drive 5:1 reduction
HXT 80-100 180kv
DIY disc brake adaptor with 52T SS chainring
16T freewheel (to be upgraded to WI freewheel)
Simple 100A ESC (6s max) (to be upgraded to either a CC 140HV or 100HV running 12s)
6s 5000mAh lipos
Diy Rack
Simple servo tester (to be upgraded to Magura?)

Very slick. Well done.

 

[Grinhill]

Well done, looks like you have already completed a build very similar to my latest project!

Would love a few more photos from different angles, please.

Do you think it would be possible to fit a V-brake on the rear?

 

[sockman]

V brake is possible...just need a new frame...take em pic now

[sockman]

add stealth...

 

[D-Man]

Wow. One thing I dont get though. How you are going to put your groceries inside the topeak bag with the meat grinder inside. Or are you planning on making hamburger?

Looks to be very similar doesn't it...least you know it will work well :-|

Nice fab work there sockman very impressive.

Recumpence has the servo tester/throttles your after in a 'kit form with assembly instructions too Sockman he also have the HV110 ESC you mentioned....

D-man,
Its a empty shell...top portion will hold the batteries and controllers, the meat grinder area is a metal roll cage...to protect the motor in case i fall

AussieJester,
I'm fabricating a simple throttle now using an old rc transmitter trigger and a servo controller kit...(while waiting for the proper throttle to arrive >1 mth backorder)

just did some testing and the ESC is getting warm when using the new throttle...it seems like its not return to the zero position...just hope it doesnt kill the esc...fortunately the CC ESC will have the option to set the throttle position easily. will have to check with matt if he is selling the CC ESC.

 

[recumpence]

Looks good

Yup, I sell HV110 controllers. I can preprogram them and add input caps as well.

I remember machining that drive!

[sockman]

matt,

your drive is fantastic...will be doing more speed and distance testing after fabricating the throttle ...

just send u a pm regarding the hv110

cheers,
russ
so many parts to buy...so little $$ left...

Great build, Sockman. From your specs you got 21-mph from 22V ? If you were doing another bike, is there anything you'd like to do different?

 

[sockman]

my final target for this build is 70km/h with a range of 80km...and can be lifted with one hand.

things that would be nice
1. seriously thinking of doing it on a trike, for the stability and ease of control and comfort
2. right side drive with shifting

 

[recumpence]

That is cool.

Are you moving this drive to the trike?

Most trikes use 2 inch OD frame tubing. I have two inch drive unit/frame clamp in stock.

You would need a two stage reduction, though, to drop the RPM down enough for right side drive through the derailer.

Matt

 

[sockman]

This drive will stay...will most prob get a new one from you for the right sided build...

have some tots after reading the parallel drive thread...

wouldnt it be possible to fabricate a spline mount for a ENO freewheel to add to a standard freehub,...convert the human power portion to a single speed to the ENO, and the electric power to drive the derailer system (of cos consideration must be given to the chainline)
it will be more logical with less reduction needed and almost no modification to the rear wheel

That is cool.

[recumpence]

Yes and no.........

You will still need a freewheel on the drive system output or you will be driving the motor when you pedal.

For dual independant drive, you almost always need 3 freewheels unless you run a left side second chain or two freewheels on the right side of a hub, which at this point in time, is not possible.

We are working on it, though.
