ouch. congratulations... enjoy that. :lol:

the hs3540 should arrive next wednesday. should have paid for air delivery!

meanwhile, i cut out 8 working cells on my first ebike battery, a 16s ping, for use on the nanny bike:


at the end, you many notice me testing a puffy lipo cell and then opening the garage door... :twisted: i really need to take a load to recycling, but curiosity got the best of me. it was too dark for the camera in the middle of the alley. after jabbing it for a while and barely a puff, i finally wanted it dead, so i aimed the propane torch at it and finally got it to burn, and very gently at that. here's the remains:
20120426_071627.jpg

it had < 1V, fwiw.

earlier yesterday, i'd heard about an MTB trail at fort dupont in SE DC. most trails in DC are strictly no bikes allowed, so i thought i'd check it out.

15miles total. had to go slow to conserve juice. enjoyable trail ride, especially using low gears, but nothing technical and it all looked the same!

some highlights in here, but the am commute may be more interesting... :twisted:

Awesome! I love the non-chalant gum opening white cruising. You must have some serious trail on that bike to get that much stability. I gotta build a faster bike...

I stumbled into a huge quarry/building site type thing the other day and thought of you. I was sooo tempted to go for a quick squirt around the pit and lauch off one of the big dirt piles but figured the workers would shit bricks and with a scratched gopro lens it wouldn't have made the best of footage :P

yeah, i was a bit discouraged awhile back and stopped posting as much. guess i'm over that and back to my tricks, but they're mostly calculated risks - i'm rarely going for it 100%, execpt for a tight pass here and there. i'm really struggling to come up with a good youtube name to separate the nasty vids. 'badebiker' has been taken... :lol:

Its nice when you have kids to get out in to the solace of the garage and do some ebike work 8) I really enjoyed swapping out an old wheel bearing on my X5 the other night ha ha, I have to go out to fix the clutch on the BMC sat morning, my little boy will most likely join me, its the cutest thing when he sees my bike upside down he turns his little bike over too!

Great to see you back to your old tricks mate :D

Got be kidding binlagin... I can push it alot harder, play with small motorcycles and go away without even being noticed if I dont keep pushing over 40mph all the time in a clean lane.... in the traffic jam I dont go faster than that between lanes for safety but Im sure I could ride even faster without being noticed.
But I live in a big city and laws are done aiming the mass and I hardly see any ebike. I usually respect the top speed alowed and slow down to cross a red light and thats it.

A decent 25mph bike will cost around $1000.
A decent 35mph bike will cost around $2000.
A $1000 35mph bike will get you killed.
Justin we really appreciate what you did!

I'm getting old too..

The scars from what my friend described as a 'spectacular crash' have not had enough time to heal - today hit a tree at speed on my mountain bike (not electric :roll: ), ricocheted towards the river ad hit the 2nd tree in full flight with my back, same spot as 2 weeks ago :twisted: Was hanging off the edge over the water with the bike hanging off the top of the shoe. The rear wheel just touched the water.

Sunnies came off from the first hit on the clavicle. I got up, brushed off and kept riding (a little slower) still took every jump :lol: Two hours later started to have difficulties breathing so went to the emergency department and had an X-ray suspecting a cracked rib. No bad news so far.

No video, but pictures to follow :mrgreen:

PS hope I'm not spamming :lol:

jeez, i'm dizzy just reading that. :( good thing you're made of titanium! :lol:

is it just me or do tight paths in the trees seem a bit hazardous?

and yeah, hy, thanks for reposting your cemetary classic.

Back at college, this was a great place to, um, hang out... :mrgreen: incredible views of the city. choice real estate. Georgetown U owns it and was gonna disintere the graves but has to wait till remaining holders die... so no real disrespect..

meanwhile, i'm starting to play with other controller locations... i need also to consider it being 6fets longer :twisted:

and i'm not fond of existing pack, so going to play w/ some other ideas.. i really don't think i'll need to be removing the pack much, so might fill up the space...

Hey GC, here's the setup I've made out of one long sheet of 6" by 6' of 1mm aluminium. Made a little homemade wooden, sheet metal brake, works like a charm! I'm able to fit 24s, 88.8v, 10ah. I could probably fit 30s in if I changed up the position of some of the bends. http://i.imgur.com/XsV91.jpg

Noticed scars on the trees in the photo, like they've been hit before, or does that just mark the trail? Hope you are ok, get better soon and be out there cheating death again!

Ouch, my trails are usually more narrow allowing only one bike on the path. It keeps you alert and on your toes. You get use to watching for low cut branches and obstacles. Wide open paths with few obsticals in between can put you to much at ease. I hope you were wearing a helmet. I hit one hard during my first year of trail riding with my left shoulder. Trees don't budge and can leave quite a mark. I've been very lucky so far, and have been good at avoiding them as I get better at riding. Lots of body movement and sideways limbos while riding. It's similiar to tree skiing for me, cheaper too. You stay at a speed that you are comfortable with and work on your skills. Due to all the switch backs you can only go so fast, so crashes are usually tolerable. Just like skiing you plan out your path two steps ahead and get into a zone that's quite meditating. There is no room for other thoughts. This is really the main reason I have an ebike.

had you been trying to avoid the caved in dirt perhaps? only to get a closer look?

how's the left arm now? about time for some xrays? collar bone?

uh oh, looks who's stockpiling steel... :twisted:
