hi
i,m miguelitro from spain.
my old speed bike is near to return fastest.
i use a pocket bike engine and i need only work in the sprokets , because the 700 wheel have 2 meters and it,s so longer, i need down half.
soon i,ll publish photos
:devilish:
 
hello 5 7 heaven
will try to do it in two steps. intermediate step so I can use for making a dynamo strength:eek:
'll have to do several tests in the development but that is the least of worries me.
the problem is finding the location of gears, crown and chain.


Greetings
 
Pocketbike Parts!

JMO, pocketbike parts are cheap and readily available, thru www.ebay.com or many pocketbike websites. :unsure:

Freeway mechanisms with left-hand and right-hand threads can set up your engine drive thru the bike's cassette or left-side independently. These parts will work with the SBP shift kit too.:geek:

Hi 5-7HEAVEN
Do you have a link where to buy 6 spline sprockets for the 5 to 1
transmission that use 415 chain? or other 1/2" pitch chain?

Looking for 10, 11, 12 , 13 teeth
thanks

I believe Dax has 10 and 11 tooth, and Dave Staton has even more. They use the 410 chain. Probably work with 415 too.
 
i have diferents hardware 58 to 73 teeth and atack pinion 6/8/10 the chain have to types 25h and and bigger (i don,t know metric).
now it,s dark and snowing outside but tomorrow i take pictures and post them
i have many ideas to explain to you

saludos

I talked to Dave and he doesn't have any sprockets that fit

Dax only has a 10 tooth for 1/2" pitch chain and the teeth aren't beveled

Still looking for 11, 12 , 13 tooth sprockets with 6 splines for the 5 to 1 transmission.
thanks

hello guys
this is the idea to change the engine developments.
string types riding the pocket are 25h (no trust me, is too fragile, or so it seems) so I will use thicker chain.
sprockets attack, threaded onto the clutch with Metric 8 mm or 10 mm,
in my case I will use 8 mm, because the axes of the cranks are the metric, and that's what I use as an intermediate step between the motor and the wheel.
the engine is not in the same plane as the rear sprocket so I could use this axis to align all the elements.
tarsier is the crown pocket bike and I had to machine the original hub of the wheel.
a good choice would have been a flip flop hub but here it's hard to get and also expensive.
I prefer the creativity of money.

I'm looking forward to cutting and welding.
