A 404 in a 20" wheel at 48v -- are you really planning to ride 50+ kph on that bike?
Hey
Another one!! ha ha nice! yes the brakes will be the weak point, my BMX doesnt stop very well! ha ha, hmm I dont do more than 25mph on it for that reason unless testing.
The BMX is a great platform, total fun, no peddling, they handle very well as they are a short wheelbase and nice and low, Its certainly the most fun ride I have in the stable of bikes here and that includes the KMX so its got stiff competition.
Keep us posted on the bikes progress, pop the batteries on a rear beam rack like my bike, job done, its one sure fire way to get noticed I tell you! just watch for that front wheel on the loose stuff, they spin so easily.
Looking forward to some video and more pictures.
Cheers

I plan to try all sorts of things on this bike, including dual motors.
Yes, it will be high-speed, but i will be able to compare it to the dual speeds and the X5's..
Knox : yeah, the bmx is looking sweet, nice flat dropouts, low to the gruond, light, i'm surprised there are so few around !
I got the controller mounted, throttle, and she's ready to go !
Hi
Yes they are a great platform for a cheap fun e-bike for sure, mine gets used all the time running errands in to town and just having fun in the park, its nice to rest your legs once in a while as I do a lot of normal cycling (I dont own a car) so all my commuting is done on e-bikes.
Yes please post up some more pictures and video when you get it done, I have only seen 1 x more electric BMX that had a hub motor a few months after i made the first video of mine, he was using an xlyte and even had his batteries in a ruck sack! ha ha, nice.
Maybe we will start a trend here, if all the little emo kids started riding them we would be off!! ha ha, those kids don't bother with brakes at all do they! a BMX with brakes? whatever next! ha ha.
Yes please post some follow up pictures, I haven't built a new e-bike for about a year so getting withdrawal symptom's! ha ha.
Cheers

Just wondering if there is a reason you chose to use a front Hub motor versus a Rear motor. I want to build a BMX as well, but I was thinking of using a rear hub motor. I figure a rear motor will give you less wheel spin and better handling. I notice all the BMX bike builders however seem to be using front motors, so I'm wondering what you experienced builders know that I obviously don't.

Front dropouts on a BMX are generally thick and strong... 
reason no 1
I have a pile of front motors on hand, with spare covers for rear conversions, no reason it can't go rear, but for the time being it's going in the front for testing, and i think a bit of front wheelspin in the soft stuff might just be a bit o fun !!!

Alrighty.... just got back from a run !
Damn this thing is fun ... i'm running 36v sla 12ah right now in a backpack..
... but i'm goin to the post office in a few hours to get my new LiFeP04 pack !!!!! that should spice things up !!!

Uhm... i swear that never happened to me before ... :lol:
I usually take months to plan a bike setup, but the BMX has been on the to-do list for a very long time, the execution was all thought out i suppose.

Get a room!
I can't imagine going 20 miles on it as is... i'm going to fit a suspension seat post or something to it eventually. and possibly a disk brake front fork if possible.. ( not on this frame, but my next one !! .. yes.;. there will be a next one !! EMX-2 )
I took it off-road and it holds up well.. it's a rough ride but solid, the 404 is made for a 16" wheel, but i want to try it at 48v 40 amps for fun ... then swap back to a slower motor for the dualie setup ! :wink:

I highly recommend the Cane Creek Thudbuster.
http://www.thudbuster.com/products.html
130 $.. not too bad.. cheaper than some other suspension options..
so that's 2 things i need now.. a CBA II and a thudbuster ! lol..

I too would recommend the Thudbuster. Check out ebay for possible deals.
Are you going to try a 406 on the front?
Selfish interest
on my part , or can you extrapolate from the 404?

The 404 was a bad choice for a BMX, too fast at 36v in a 20" rim.
In a 16" rim it would be great, but i want to run 48v x 40 amps and a 405 or a 406 would be better .
I like a bit of grunt off the line !
The 406 can be next if you like ! :wink:

That would be great Y
Since, I already have a 36V battery pack I would be interested in how that compares to 48V if I understand your intentions.
Did you comment somewhere that it is possible to convert a front hub to a rear by changing the side cover, or did I misunderstand?

i'm wanting you to try a 406 too - but two of them
My Giant currently has a 407 in the front and a 408/4012 in the rear, my single cell LiFe chargers crossed the border last night according to the tracking info.. should arrive hopefully by friday this week ! :wink:
The BMX with dual 406's might work well with dual 40 amp controllers at 48v.
