Farfle's Race bike

[bzhwindtalker]

Are those the 6s 8ah? Thats probably my next battery buy. How will you secure them to the frame?

Great build!!!
Finally someone putting a full suspension 20 inch bike together that does not weigh a ton and is strong as an ox. Also like the stealth real bike look.
Super job on the swing arm.
Love the idea of just modding the lower arm and keeping the rest stock. Makes duplicating this easier than having to fab a hole new rear assembley.
Who made the swing arm?
Keep up the great work. You have raised the bar.

Thanks mate . hoping it performs as well as it looks! got the rear wheel spinning today, albeit the wrong way

[Jay64]

Great build man. I look forward to seeing it.

Just turn the bike around and hammer the throttle. You might need to get some bar end mirrors or something though.

Good news Battery mounting is done Bad news... not posting anymore pics until the race!

CHICKEN!

CHICKEN!

That's me, maybe one more picture tho...

It that a saw blade you re-purposed as a disc?

I noticed the old fashioned expansion slots/plugs.

[Whiplash]

It does look like a diamond blade doesn't it?!!

Very good eye, it is indeed a saw blade, $20 harbor freight cheapo 12" thin kerf blade, bolted on with the sidecover screws.

Ok, how well does it work?

I've been trying for months now to find something large enough to fit outside the older 9C 2807's diameter far enough to still allow calipers to clamp around it, but hadn't found anything yet. Been trying various motorcycle shops and people who have them, etc., with no luck yet (usually getting laughed at, called a moron, or just plain ignored).

I thought about cutting a circle out of a stainless steel tabletop I have, but it's too valuable to me as a tabletop, unless I simply can't find anything else.

I looked at all sorts of other things I could repurpose, but had somehow not thought of saw blades.

I'm pretty sure I can find one of those used, in sufficient diameter, so if it actually works well with bicycle disc calipers, I'd be happy enough with that. Can't be too hard to cut the right inner circle diameter out of, and drill the bolt holes.

Looks like you will have "some" braking power with this disc and your tire choice

[dbaker]

Now to make the caliper mount

[veloman]

Flip that stem and get rid of the riser bars to get lower. A race bike shouldn't have you sitting upright at all. You wouldn't have as much of a problem with flipping over with lots of torque, and you would be more aero.

[bzhwindtalker]

now that the race is over, could you give more details on this racedog? I saw you had a Kodak playsport bolted on the forks, please upload some HD vids

[Farfle]

Here's a couple pictures of the bike, we are still driving home, but will be here some nice HD video, and a better image of the caliper.

[nicobie]

After seeing the bike in person, about all I can say is that it impressed the heck out of me. Lots of small details well done. Definitely not crude.

The rider wasn't too shabby either...

And I'd really like to know how the sawblade brake disc worked out.

[Thud]

I took this bike for a short spin araound the pits.
The rear brake worked just fine! & I was quite impressed with the pull this motor/battery combo displayed even at the end of the battery cycle....nothing like a twin Rc powerd super bike, but definatly falls into the Performance catagory (with a capital "P") this bike was the one to beat before LFP arived with the murderers row of e-bikes (paulD & his own Golden motored tire burner)

It was fun watching Jay64 scrubbing the tires around the race track for a couple short laps before sutting off due to low voltage & not wanting to destroy Farfles already abused batteries.

I can only imagine how it accelerated with the Lightweight Jockey (ringer ) team farfle brought down to demonstraight the build. Good Job all the way around & the details were all covered. Truley a great build.

Farfle offered the bike up and I got on not expecting much having missed the races, tested the throttle and WRF did it just pop a power wheelie??!! Gunned it and the grin came over me. I handed it to Thud and said you have got to try this bike out! I have to be honest, I never thought a hubmotor would impress like this bike, and on half dead batteries nonetheless. Saw disc worked a treat too, I would have never known it wasn't standard equipment if he hadn't told me.

We want vids man! I want to watch on BIG screen! Lol. See you guys at the Death Race in April!

A couple of race photos of this awesome bike-






I too greatly enjoyed taking a spin up and down the pit row on this fast and well-sorted bike. Kudos to Farfle for building such a balanced, well put together bike, and congrats for the 2nd place finish!

[AussieJester]

I hadn't noticed the 'pegs' you have added, unitli seenz them in the pics with Aiden riding the bike, first i thought they were
your version of crash protectors as per used on faired motorcycles
to help decrease damgae in the event of the eniventable fall...THEN i notice them in the pic
of it on the motorcyle-ishkay stand, very clever Farfle! very clever indeed!...i think they
would also double as crash protectors to, though

Well done too Aiden, great to see a e-wiminez in mixing it with the bois And congrats to
you on such a well presented frocked e-racer Farfle, its a very impressive turned out e-bike with
performance to match..

Congratulations on such a well thought out race entry. Love the way the steel wishbone came out.

Coming in second just proves what I learned in the DR last spring. The rider is the key element, once you have a reasonably fast bike put together. Your gal must be awesome! Clearly Paul is.

[Farfle]

Definatly hooked on racing... next year may include a monster 110kv 200mm outrunner, a whole lotta 4110s and some optical sensors... my wallet is gonna hate me...
