Non-overclocked Vector Light Build

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
kls7230s.jpg
scratched.jpg
bottom plate is scratched up. is this normal?
adapter.jpg
adapter cable has bare wires coming out :roll:
shocks.jpg
forks.jpg
rims.jpg
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

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: Select all

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

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

frame is here! seems like this is the latest revision :thumb: headtube accepts tapered fork (the included headset accepts both tapered and straight steerers). dropouts are clamping.

thanks Artur for this great frame!

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)

the Grin (www.ebikes.ca) spoke calculation was spot on :thumb:

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)
