as the title suggests this will be a somewhat "low" power build but i'll still try to maximize the thermal capacity of the hub motor which would be the QS 205 35H 5T winding https://www.aliexpress.com/item/32816512376.html

inspired by skeetab's build w/ the funny frame color :lol:

also ordered the Kelly KLS7230S https://www.aliexpress.com/item/32888145048.html

shall be using parts i have lying around:

-Marzocchi drop-off triple 170mm travel
-Rockshox sektor gold 150mm travel
-Marzocchi roco 220mm 300lbs spring
-DNM rcp-2 220mm 550lbs spring

will try 2 wheel size combos:

1) 26" front, 26" rear
2) 24" front, 17" moto rear

jszh vs 26f (Medium).png

i'm taking a gamble w/ these cheap (PHP95 or USD1.86 per piece, landed) chinese cells made by JSZH (jiangsu zhihang new energy). i've cycled a cell and got 97.8% after 152 cycles :shock: that's pretty good cycle life!

3A discharge curve compared to samsung 26F

here's the raw data from the cycle test. in retrospect i set the LVC too low at 2.5V :lol: if you look at the discharge curve it begins to fall off the cliff at around 3.2v. but this didn't seem to hurt the cell at all :lol:


Code:
JSZH 18650 2600mah TEST!
charging time: 2:06 == 126 mins
rest: 0:05
discharging time: 0:54
rest: 0:05
TOTAL: 190 mins == 3.16~hrs per cycle

1.5a charge, 3.0a discharge, 2.5v cutoff

working fine. i'm a kelly noob btw. the pink #7 wire sparks when i connect to B+. apparently that's normal based on the other threads i've read. kelly's wiring diagram also doesn't specify a precharge resistor for the pink wire

speaking of precharge the 1kohm that's included charges way too slowly. i guess xt90-s is OK to use? 17s pack btw, 71.4v max

strange knurling inside the head tube...

also strange that Vector decided to use a full 1.5" headtube. forks that use straight 1.5" steerers are quite rare. the "integral" type headtube is simple to machine, lighter, and accepts tapered forks using an appropriate bottom cup

geometry seems OK w/ this configuration. 26x2.35" front, 17x2.5" rear. i want as small rear wheel as possible since this is a DD hub. if it looks awkward i will go w/ 24" front wheel and the longer dual-crown Marzocchi to maintain more or less the same geometry (the 24" will drop the axle around 1" but the Marz should compensate by having a longer axle-to-crown)

Nice, but you seem to get some bend in the spokes? I plan to have one out, one in of the crossing spokes on my wheel build. But we will see how it goes.. Where did you buy the spokes?

the spokes are from greentime. slight bend is OK. i'll retension after they bed in

here it is w/ 26" front and 17" rear. IMHO it doesn't look too awkward especially when you consider the benefits of having a small rear wheel in a DD hub (and also the advantages of having a large front wheel)

Nice looking build so far. The wheel diameter difference doesn't look bad at all.

That is a beautiful looking battery pack. What is the max current you plan on drawing from it?

Ouch! I would have taken a ride to the hardware store :)

hats off to you

haha but i did! they didn't have the exact size. it's a good opportunity to use the tap & die set anyway, these dies (dice?) get rarely used.

finally got it running! the KLS7230 is too big (obviously) for this build :lol: both in terms of amps and physical size :lol: i might a KLS or KBS mini. i like that these controllers can read the KTY-something-something sensor inside the hub to protect the hub from frying. i hit over-temp twice during this short ride
