Re: where can I find a steel front suspension fork?

well even aluminum dual-crown forks eventually fail due to metal fatigue. usually at the stanchion just below the lower crown. so i opted for this rockshox domain w/ steel stanchions

new custom crankset w/ short 152mm arms. i'm getting pedal strikes w/ the "normal" 175mm arms. also added a 48t chainring because 152mm cranks NEVER come w/ 48t :lol:

short arms ideal for ghost pedaling :lol:

Re: New build, BHT mid-drive "direct", custom frame

Well done with keeping the bolt and key/keyway. I hadn't had any issue with the quick-lazy of welding it, till I also tried quick-lazy with removing it lol.

it certainly looks powerful, hows it go on those flats this is where the hub motors shine! those are the volcanic sands coughed up by Mt. Pinatubo in the early 90's (which cooled the earth by about a degree). this hub does well on pavement and hardpack. but terrible off-road :lol: so it's never goi...

Re: Non-overclocked Vector Light Build

Looks cool with the battery showing thru the side panel, be careful of a short! would hate to try to pull that battery out in flames! I always think of that when there are 10x screws locking it in place inside the frame. I'm sure its a ton of fun with that controller, but make sure you have enough ...

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...

Re: MIG Welding questions

so a few months back i went ahead and got a 20lb tank of co2 and regulator. didn't cost much. in retrospect MIG is actually "cheaper" than flux-core since good fluxcore wire is expensive and not copper coated so it rusts, you can't keep it for a long time :evil: just as the OP said MIG does have a "...

Re: OpenEMoto

w/ garage built frames the limiting factor is fabbing complexity as trazor has mentioned. it's easy to design in CAD but the difficult part is actually building the damn thing. so the design goal is "good enough" rather than "best" hence no suspension linkages and such. these frames are tough to bui...

Re: A low-cost e-MTB Production log

too similar to neematic i.e. a ripoff. not good for business to be labelled as a copycat. check out the surron original design. it's easy to come up w/ a totally new design. i've done it with coreldraw in my garage
